David Thorpe: A Look At Three Wide Aperture Sigma Lenses For Micro Four Thirds

“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.
