…So I’ve been shooting with full-frame cameras for 17 years now and here we are in 2019, when full-frame cameras are taking over the popularity contest and Sony in particular has been killing it in well earned reviews, why would I even consider switching to micro four-thirds – a sensor size that is tiny compared to a full-frame sensor? Why would I leave the Sony a7R3 with it’s 42MP (and just announced Sony a7R4 60MP camera) and switch to the Olympus OM-D E-M1X and it’s tiny 20MP sensor?…
The Micro Four Thirds sensor system co-founded by Olympus and Panasonic over a decade ago is particularly well-suited to documentary photography and moviemaking as well as to the wildlife photography practised by Matt Seuss.
Recent M43 cameras like the Olympus OM-D E-M1X and Panasonic’s DMC-G9 with their multi-exposure high-resolution modes have become attractive to landscape photographers needing to produce big, really big, prints and I look forward to high res evolving rapidly so it is more applicable to in-studio and on-location portraiture as well.
Meanwhile I applaud Mr Seuss’ choice to invest in Olympus’ excellent M.Zuiko Pro prime and zoom lenses for M43 cameras including those made by Olympus and Panasonic as well as Blackmagic Design on its Blackmagic Pocket Cinema Camera 4K.
Olympus’ M.Zuiko Pro lenses are excellent for stills and video, especially due to their manual clutch focus mechanism with hard stops at each end, a feature I wish to see on all lenses for cameras in all sensor formats from now on.
It has been good to see Panasonic finally get the memo on manual clutch focus with their first M43 attempt at including it as a key feature on the Panasonic Leica DG Vario-Summilux 10-25mm f/1.7 Aspheric zoom, a lens I have been hoping would eventually appear ever since I invested in the Micro Four Thirds system.
Last month at the CP+ show in Yokohama we spoke to executives from several major manufacturers, including Sigma. In our conversation with CEO Kazuto Yamaki we discussed his plans for future L-mount lenses (and cameras) and some of the challenges of supporting multiple mounts.
I am looking forward to seeing and trying Sigma’s Art collection L-mount prime lenses scheduled for release sometime this year and that are adapted from the company’s current DSLR Art collection offerings.
One major bugbear of new mirrorless launches such as those of Fujifilm APS-C and medium cameras, Panasonic’s Lumix S1 and S1R 35mm cameras, and Panasonic’s Micro Four Thirds cameras is the relative paucity of lenses.
Canon took 30 years to come up with its near-complete DSLR lens collection and it may well take Fujifilm, Olympus and Panasonic almost as long to flesh out the many gaps in their lens collections.
Professional photographers and cinematographers rely on the availability of large lens collections for their cameras in a way that amateurs and enthusiasts tend not to, especially when relying on prime lenses for their optimum optical and mechanical quality.
I would love to see Sigma creating lenses for Fujifilm X-mount APS-C cameras given there are so many glaring holes in Fujifilm’s lens lineup, and the same desire applies to professional-quality lenses for use on Blackmagic Design, Olympus and Panasonic M43 cameras.
Panasonic and its L-Mount Alliance partners Leica and Sigma have done well to aim at releasing enough lenses to satisfy those contemplating investing in the L-mount camera system, and it is pleasing to read that Sigma will be working on smaller and more affordable L-mount lenses in due course.
Meanwhile those of use needing focal lengths that Fujifilm does not offer for its X-mount and G-mount cameras may need to bite the bullet and rely on adapted EF-mount lenses instead of the much-preferred native X-mount and G-mount alternatives that simply do not exist yet.
I am still hoping for a professional-quality alternative to Fujifilm’s too-quirky, too-slow Fujinon XF 18mm f/2.0 R prime lens with its 35mm sensor equivalent focal length of 28mm, a staple optic for many documentary photographers and photojournalists, me included.
“At a time when Olympus and Panasonic lens prices are going through the roof, Sigma offers these three f/1.4 ‘Contemporary’ lenses at sensible prices. Do they sacrifice sharpness, focus speed or build quality to price? Having owned, used and reviewed – many Sigma lenses over the years, I didn’t anticipate any nasty surprises and I didn’t find any. There were some nice surprises, though….”

Former Fleet Street press photographer David Thorpe is one of the least-known yet most-respected YouTube reviewers with a speciality in Micro Four Thirds system cameras and lenses, though I suspect he will be bending that speciality soon with coming reviews of Panasonic’s Lumix S-Series S1 and S1R 35mm sensor format cameras and lenses.
I have no hands-on experience of Sigma lenses whether prime or zoom, though I was lucky enough to inspect Paul Leeming’s Sigma 18-35mm f/1.8 DC HSM Art zoom lens with Canon EF-mount that he has adapted for his Blackmagic Pocket Cinema Camera 4K and was impressed enough with its optics and construction that I am hoping to buy one of my own some time soon.
Clearly Sigma has something good going for it with its membership of the L-Mount alliance alongside Panasonic and Leica, and Mr Thorpe’s review of these three Sigma Contemporary collection prime lenses supports that impression.
With their 35mm sensor format equivalent focal lengths of 32mm, 60mm and 112mm, and fast, wide maximum apertures of f/1.4, and very reasonable pricing, these three lenses look well worth considering for use in stills photography.
I am now looking for some hard-core technical reviews of them for consideration as video lenses too.
My current impression of Sigma’s Contemporary lenses is that they are designed to work in connection with in-camera and image editing raw processing software for correction of any possible optical distortion, whereas Sigma’s Art lens collection that includes the 18-35mm f/1.8 zoom is reportedly designed to the finest of optical standards to obviate the need for correction in software.
That aside, I have been looking for a medium telephoto portrait lens for Micro Four Thirds for some time now, and Sigma’s 56mm f/1.4 DC DN C may well fill the bill.
I originally got into portrait photography with Nikon’s Micro-Nikkor 105mm f/4.0 lens and focal lengths closer to 105mm in the 35mm sensor format are my first choice for work in the genre, so the 112mm equivalent of the 56mm lens is not a bad approximation.
The Sigma 56mm offers the advantage of a wide aperture to blur distracting backgrounds if necessary.
Similarly, I discovered long ago that my preferred main focal length for immersive documentary and photojournalism work is 28mm in the 35mm sensor format, and Sigma’s 16mm f/1.4 DC DN C with its 32mm equivalent focal length is not too far from that.
I like to be able to use my lenses for cinematography and photography, and prefer lenses that perform well in both applications given raw processing can correct optical distortions in still images but non-linear editing software cannot do the same for video.
My favourite raw processing software for raw files shot on Panasonic cameras is DxO PhotoLab so I am hoping that DxO has added camera-and-lens profiles for all three of these Sigma lenses for recent and current Lumix cameras to its database.
Off to DxOMark and time to drop into some camera stores to touch, try and shoot some sample pix with these three lenses so I can crack some raw files open in DxO PhotoLab, DxO FilmPack and DxO ViewPoint.
“At the CP+ show earlier this month in Yokohama Japan, we sat down with senior executives from Fujifilm. During our conversation we covered everything from the upcoming GFX 100, to plans for APS-C and why the X100 still occupies such an important position in the company’s lineup.
Our interview was conducted with three senior executives in Fujifilm’s Electronic Imaging Products Division:
Toshi Iida, General Manager.
Makoto Oishi, Product Planning Manager.
Shin Udono, Senior Manager of the Sales and Marketing Group.…”

“Moving to the smaller, lighter, less expensive Panasonic Lumix Micro Four Thirds cameras has made my photography travel life much more enjoyable. Gone are the days of carrying around 12 pound lenses. Getting the most from the smaller systems I’ve started following what I call the Micro Four Thirds Triad. This first video, of my two-part series, explains the cameras and lenses needed to follow the Micro Four Thirds Triad. Watch this video to find out how you can downsize and still get the most possible out of these smaller cameras that save you cash and physical pain. Part two will be released shortly that explains the last part of the triad which is software. Software that solves most problems we have with the smaller cameras so you can produce images that compete beautifully with the larger full frame systems….”
It is timely that wildlife photographer and Panasonic Lumix Ambassador Daniel J. Cox has released his two video about the Micro Four Thirds triad – cameras, lenses and raw image processing – when Panasonic’s Lumix S-Series 35mm sensor format cameras have been announced and are now showing up in touch-and-try events at camera stores around the world.
There is plenty of life left still in the M43 sensor format for photography and video, and many M43 users will doubtless be resisting the temptation to swap over to the larger 35mm sensor format, also misleadingly known as “full frame” and “full format”, and its consequently larger, heavier and costlier cameras and lenses.
I have yet to experience the pleasure of touching and trying Panasonic’s Lumix S1 and S1R cameras and lenses, and am looking forward to several touch-and-try events in Sydney CBD camera stores next week.
Right now I do have some years of experience using Panasonic’s excellent little M43 camera and lenses, as well as Olympus’ M.Zuiko Pro professional-quality lenses, for photography and video, and can attest to the high image quality that can obtained from the M43 sensor format.
When I first tried out M43 cameras and lenses, I was struck at how well-suited they are to documentary photography and photojournalism due to their small size and oftentimes innocuous appearance quite unlike that of the big and heavy DSLR cameras and three-zoom-lens kits of which my former magazine and newspaper colleagues still seem to be fond.
There is nothing wrong with larger cameras, as I amply proved every day during my editorial photography career when I would rely on 4″x5″ sheet film, 120 roll film and 35mm rangefinder cameras far more than I did on the regulation 35mm analog film SLRs of the day.
The Panasonic Lumix S1R with its almost-50 megapixels of resolution, for example, is an intriguing proposition for shooting portraits to be printed extra large for exhibiting in gallery shows.
But meanwhile Daniel J. Cox is sharing some good advice in these videos on how to produce image files large and detailed enough to print up to 24″ x 36″ for exhibition and sale to collectors.
I can attest to the quality and speed of using Mr Cox’s number one raw processing software choice, DxO PhotoLab, as well as the utility value of ON1, Inc.’s ON1 Resize 2018 software which is also available as a component of ON1 Photo Raw.
I note that he lists Phase One’s Capture One Pro as his second choice for raw image processing and image editing, and can attest that it makes a great choice when processing Fujifilm X-Trans image files which are, sadly, not supported by DxO PhotoLab.
I often carry a Panasonic M43 camera alongside a Fujifilm APS-C camera, most often my X-Pro2 along with my Lumix GX8, for their distinctly different ways of seeing and recording the world, and it can be difficult to tell which picture was shot with what camera when processing both in Capture One Pro, especially when applying film simulation styles from any of 1stylespro’s three collections – Portrait Styles, Film Styles or Film Styles Extended.
“…We’re in Dubai, where Fujifilm is showing off pre-production and prototype samples of three upcoming lenses – the GF 50mm F3.5 – a compact, lightweight standard lens for medium format – the XF 16mm F2.8, and the XF 16-80mm F4 – both of which [were] designed for the company’s range of APS-C format X-series cameras.
Click through for an exclusive first look at all three, including detailed specifications….”
As time is inching towards the release sometime in the first half of 2019 of Fujifilm’s Fujinon XF 16-80mm f/4.0 “travel” zoom lens it is terrific to get some idea of its size and features and other it may provide a solution for own needs as a documentary photographer and videographer.
I am self-funded, only able to carry a small amount of hardware on each project, and must work within ongoing limitations – thanks for nothing, Australian banksters, for blowing our refinancing out of the water after you were found out for your crimes by the Royal Commission into banking.
I must be able to get the most out of the hardware I carry and it must be able to help me create good enough movies and videos without the benefit of cases full of equipment, assistants and crews, and the big budgets that I never had anyway when working as a magazine editorial and corporate photographer during the analog era.
Gaps in their offerings
As two relatively new camera and lens systems, Fujifilm’s APS-C sensor format X system and medium format G system still have gaps in their offerings, especially for documentary types like me who prefer to rely on fast prime lenses with all the manual controls that can be had.
Not to say that I do not appreciate zoom lenses now that their optical, mechanical and image quality are so good nowadays.
I also use and love Panasonic’s Micro Four Thirds cameras and Olympus’ M.Zuiko Pro lenses, with my most-used lens being the Olympus M.Zuiko Digital ED 12-40mm f/2.8 Pro zoom lens and, had it been released at the time I bought my first Panasonic camera, I may well have chosen the Olympus M.Zuiko Digital ED 12-100mm f/4.0 OIS Pro zoom lens instead.
Slower zoom lenses are fine so long as you supplement them with moderately wide and moderately long fast aperture prime lenses for available darkness documentary work and portraiture, and Olympus offers three of them in its M.Zuiko Pro range at the moment, with more to come I hope.
Going fast to begin with
At the time I bought my first interchangeable lens Fujifilm camera, the company did not offer a standard zoom lens like those above made by Olympus or their Panasonic equivalents, so I invested in a Fujinon XF 23mm f/1.4 R and Fujinon XF 56mm f/1.2 R, well answering my fast aperture moderate long and wide needs.
Another longstanding need has been for a professional quality 18mm prime lens equivalent to 28mm in the 35mm sensor format and 14mm in the Macro Four Thirds sensor format.
With little sign of Fujifilm offering such a lens any time soon, I have had to consider other possibilities including adapting an EF-mount Sigma 18-35mm f/1.8 DC HSM Art zoom lens to X-mount, but this solution is best suited to DSLR-style cameras like the X-T3 rather than the rangefinder-style X-Pro2 that is much more effective for hardcore immersive documentary photography.
My interest in the coming Fujinon XF 16-80mm f/4.0 R OIS zoom was piqued when I borrowed a Fujinon XF 18-55mm f/2.8-4.0 kit zoom lens for my first tryout of the X-T3.
I loved its 18mm widest focal length, rarely used the lens at 23mm and 55mm as I was also carrying my X-Pro2 equipped with either of those two lenses, and would have loved access to longer focal lengths than 56mm for those times I could not get close enough.
DPReview’s hands-on with the Fujinon XF 16-80mm f/4.0 R OIS WR zoom provides a reasonably reliable impression of the lens in its shipping form and confirms it has a marked, clicking aperture ring and weather resistance, though no manual clutch focus or, probably, no clickless option.
The X-T3’s firmware offers the ability to switch focus-by-wire from non-linear to linear so I will be giving that feature a tryout during my current X-T3 loan period over the coming days.
Two out of three
Two out of three ain’t bad for the Fujinon XF 16-80mm f/4.0 R OIS WR zoom.
As I am not a fan of the neither fish-nor-fowl 16mm focal length, equivalent to 24mm in the 35mm sensor format, the Fujinon XF 16mm f/2.8 R WR “Fujicron” lens is not on my wishlist which is topped by the Fujinon XF 14mm f/2.8 R annual clutch focus prime lens to tackle the ultra wide end of things and has a 58mm filter diameter, meaning I can easily add a knurled brass Breakthrough Photography step-up ring for my neutral density filters when shooting video.
Although I would prefer to have a set of wide-aperture manual-clutch-focus primes for all my documentary moviemaking and photography, the Fujinon XF 16-80mm f/4.0 R OIS WR zoom would provide a range of my most-needed focal lengths – 18mm, 23mm, 27mm, 56mm and 70mm.
In 35mm sensor format terms, that is 28mm, 35mm, 40mm, 85mm and 105mm, and a limit of 120mm at the long end will account for those rare times my feet are unable to do the zooming.
Fuji Rumors has republished images and information about the northern hemisphere fall aka autumn 2019 (southern hemisphere spring 2019) release of the XF 16-80mm f/4.0 R OIS WR including these from Japanese website capa.getnavi.

There are other lenses available that receive good reviews and are suitable for architectural photography though they are too ultra-wide for documentary photography, the Samyang 12mm f/2.0 NCS CS X-Mount at 18mm equivalence and Venus Optics Laowa 9mm f/2.8 Zero-D at 13.5mm equivalence in the 35mm sensor format.
If only one lens it is to be, then the minimalist option makes sense as I rather like the Fujinon XF 14mm f/2.8 R’s 21mm equivalence for figures in landscapes, emotive close-up documentary shots, and architectural and cityscape work.
This lens will need Fujifilm’s VF-X21 viewfinder sitting on top of my X-Pro2 as a 14mm field of view falls outside the X-Pro2’s 18-56mm optical viewfinder bright frames and the X-Pro2’s EVF is not what I would like it to be.
Will the X-Pro3 improve upon that and other weak points?
If there is budget enough, then of course I would prefer the maximalist option camera and lens plus upgrading my ageing post-production facility.
The X-T3 plus grips and two zoom lenses, with the addition of my three current 23mm, 27mm and 56mm Fujinon prime lenses, makes a good Super 35mm video set-up combined with Fujifilm’s X-Trans 120-rollfilm quality stills.
The Fujinon XF 10-24mm f/4.0 R OIS is an ageing lens design, however, and lacks weather resistance and appears to be at its best optically speaking from f/8.0 rather than closer to f/4.0.
I want to see Fujifilm bring it up to current standards with a Fujinon XF 10-24mm f/4.0 R OIS WR zoom that will make a great match with the coming Fujinon XF 16-80mm f/4.0 R OIS WR zoom lens, giving the equivalent of 15mm through to 120mm in the 35mm sensor format.
I have been trying out a Fujifilm X-T3 loaded up with the latest firmware in order to shoot some HLG video footage and further try out the camera’s radically improved autofocus functionality which will reportedly be getting better again in a future firmware update, possibly in April this year.

Fujifilm X-T3 with VG-XT3 Vertical Battery Grip and Fujifilm XF 8-16mm f/2.8 R LM WR lens.
The first X-T3 I borrowed was half silver and half black while the current loaner is all black, and what an unexpected and pleasant difference that has made.
I made great use of the silver X-T3 in a two-day documentary photography project and shot quite a bit of footage with its Eterna and F-Log picture profiles, on location in available darkness and the brightest of high UV sunlight.
Each time, halfway through the day I would notice my eyes becoming sore and by day’s end the soreness would be unbearable, especially in my right eye.
I am ambidextrous and tend towards right eye dominance though that is not exclusive, and with DSLR-style cameras always use my right eye to view through their electronic viewfinders.
I had attributed the unaccustomed soreness to the slowly worsening eyesight of my ageing myopic eyes, and had feared the worst for my eyesight despite recent eye tests showing expected slow, steady but not marked deterioration in vision.
I wondered whether using an EVF camera might be the cause of the soreness given I own two Fujifilm viewfinder cameras, an X100 and an X-Pro2, and use their optical viewfinders in preference to their EVFs.
But then I also have two Panasonic Lumix EVF cameras, one viewfinder-style and the other DSLR-style, and have never experienced problems like this with either of them.
This week, after extensive use of the black X-T3 for shooting video and stills, I am reluctantly coming to the conclusion that the silver X-T3 and its highly reflective silver-coloured magnesium upper body might be the reason for my previous and constant eye soreness.
I have had no eye soreness with the black X-T3 at all.
Of course, this observation about the difference between the two versions of the X-T3 is a deduction and not the result of any form of scientific test, but it is something worth thinking about when I am in a position to invest in my own X-T3 and the coming Fujinon XF 16-80mm f/4.0 R OIS WR zoom lens.
I had been wondering whether my eye soreness was the product of the EVF in the X-T3, and was worried the problem might rule out investing in an X-T3 or any other DSLR-style Fujifilm camera, but the electronic viewfinder clearly is not the source of that problem.
I used the black X-T3 in a wide range of lighting conditions throughout the weekend, in bright high-UV sunlight, deep shade and in poorly-lit train stations and experienced none of the eye soreness that I had when using the silver X-T3.
I have been asking Panasonic, either directly or through friendly staff members, to ensure that new lenses for its Micro Four Thirds system cameras have manual clutch focus built in for years now, always without positive result. Until now, sort of…
The very first M43 lens I bought for my first M43 camera was the Olympus M.Zuiko Digital ED 12-40mm f/2.8 Pro standard zoom lens, and besides its many excellent optical and mechanical qualities, the biggest reason I chose it over Panasonic’s own Panasonic Lumix G X Vario 12-35mm f/2.8 II Aspheric Power OIS standard zoom was its manual clutch focus mechanism.
Coming from decades of relying on non-autofocus, non-autoexposure cameras equipped with manual-only prime lenses, I was not ready to fully commit my photography and cinematography practises to focus-by-wire prime and zoom lenses without hard stops at both ends of the focussing scale.
There have been many times in recent years when the only way of achieving fast and deadly accurate focus has been manually, with my 12-40mm M.Zuiko Pro lens most often on my Panasonic Lumix DMC-GX8 rangefinder-style camera, in conditions where my focus-by-wire and autofocus-only lenses have let me down.
With the 12-40mm, all one needs do is snap the focussing ring towards myself, rotate it a little until the required part of the image pops into sharp focus, then shoot.
Manual clutch focussing mechanisms offer a surety of fast, repeatable, accurate focusing that autofocusing does not and, and when I was considering investing in Fujifilm’s X-System cameras and lenses, I was pleased to discover that it offers three manual clutch focus lenses.
I wish that every Fujifilm Fujinon XF and GF lens had manual clutch focus just as I wish the same for all of Panasonic’s Leica and Lumix M43 lenses.
That lack of manual clutch focus in the latter lens system heavily tipped the balance for me towards Olympus’ M.Zuiko Pro prime and zoom lenses and I hope to be investing in more of them soon.
I had thought that Panasonic was impervious to the idea of manual clutch focus for any of its lenses, until perusing photographs of the first three Panasonic S-Series lenses and discovered that, lo and behold, two of the three have manual clutch focussing mechanisms.
Thank you, Panasonic!
I hope that many more S-Series lenses will follow this fine example.
Panasonic Lumix S 70-200mm f/4.0 OIS and Panasonic Lumix S Pro 50mm f/1.4 lenses, both with manual clutch focus
Panasonic Lumix S 70-200 f/4.0 OIS telephoto zoom lens with manual clutch focus.
Panasonic Lumix S Pro 50mm f/1.4 fast prime lens with manual clutch focus.
Aperture ring on the Panasonic Lumix S Pro 50mm f/1.4 lens
A second welcome feature of one out of Panasonic’s three new S-Series lenses is the aperture ring on the Panasonic Lumix S Pro 50mm f/1.4 lens.
My ideal lens form factor for documentary stills and video in all sensor formats would include manual clutch focus to supplement the choice of linear or non-linear focus-by-wire, and an aperture ring with the choice of clickless or clicking stops.
