The Zhong Yi Mitakon 135mm 1.4 Speedmaster is a very rare and also unique big aperture portrait lens. So far only ~100 have been made and trying to find useful information on it is more than difficult, so with this review I will try to change that.
After the success of their compact and affordable f/2.8 zooms Tamron has released a small family of f/2.8 primes: we already reviewed the Tamron 2.8/24 Di III OSD, this time I check if the Tamron 2.8/35 Di III OSD is a good performer.
Most images in this review can be found in full resolution here.
So far the only native 28mm prime lens is the Sony FE 28mm 2.0. Now 7artisans is offering a version of its 28mm 1.4 M-mount lens with an optical design adjusted to the thick filter stack of the Sony cameras. This is the first 7artisans lens reviewed here, so let us find out what this new manufacturer has to offer.
Update 01/21/20: added sharpness infinity chart for Leica M10 and a few additional information regarding its use on a rangefinder camera
Since the introduction of mirrorless camera with shorter flange focal distances the usage of vintage lenses grew rapidly. With full frame bodies like the Sony A7R II or newer with 42 or 61 megapixel, it is interesting to know whether those lenses are still usable on those cameras and can be a cheap alternative for the manually focussing photographers out there.
