Sigma Art 135Mm

[Glass] Has WR for my Sigma beast, 40mm Art!

[0.435 lb] Excellent, very useful accessory for Sigma ART users

[Full-Frame] sigma art is my go to. all their lenses are so friggin stunning I can't even. just buy it.

[Leica M] This adapter was optimized for all of the sigma Art line of lenses, and I have not have problems with any of the L lenses I tried.� One of my favorite lenses that does not experience a great amount of aberration is the 135 1.8 and the 50 art.� The others show the distortion around the edges as these lenses were made for full-frame, and not Cropped MF.� �The manufacturer has included an update port, and has already made a couple of improvements through firmware updates, like more compatibility with tamron lenses (at launch it would not recognize tamrons at all), and Improved start up time when turned on and engaging the lens.� The adapter uses the camera's battery so unlike some of the other adapters it doesn't require a power source.� Great build - metal, and feels like the sigma art lens finish.� Lens feels secure on the adapter, and did not bind or get stuck and I have been using this for about 6 months aggressively.� �It has its quirks, I have seen some complain about theirs being too tight or non-functioning on arrival, but BH only provides quality products and adds that level of credibility to an overseas manufacturer/distributor.� Highly recommend.

[6.5 x 6.5 x 5"] Just unboxed the brand new Sigma 135mm f/1.8 and it is a superb piece of glass. All ready shot several hundred images and its performance is unbelievable. Worth every penny Sigma wants for it.

[1/4"-20 Female] I use this along with the Sigma 18-35mm and the venerable Nikon 50-135mm aid and they combine to cover a full range of incredibly fast and sharp lenses for the BM camera. The adapter fits well and functions smoothly with a click less iris. The Speedbooster investment is a no brainer - it turns the BMPCC into one of the nicest production tools in the business.

[Autofocus] The Sigma 135mm f/1.8 DG (Nikon F mount) is the sharpest lens I have owned - no focus problems, great build, nice colors

[0.205 lb] Sigma has already built a solid name with the Art series so no need in bragging about how good this lens is, it's a Sigma Art lens!

[3.155 lb] Sharp to the edges and built sturdy like other Sigma Art lenses. This is a go to lens for us!
