Pros: contrast and size

Cons: Nothing

Opinion: Great optics, the most loved in what was my OM kit. The sharpness is very good, for comparative tests like the Nikkor 20 f3.5, but what really makes the difference is its contrast, rich in shades with subjects that 'come out' from the images. Another of its merits is the possibility to focus at a very short distance: 20 cm, at the limit of the macro, which allows beautiful images set of flowers and insects. I don't know, and it would be nice to know, how it behaves on a digital FF mirrorless with all its IR filters in front of the sensor that literally 'kill' these 'old' optical projects, but no doubt it's one of the lenses to consider for that job.

Pros: size and weight, 49 mm filters, optical performance.

Cons: Exceptional "only" f 8 and up.

Opinion: I found a review in "The Photographer" many years ago, with the attached diagram risolvenza that says ".... also in terms of performance this tiny fisheye can be considered one of the finest examples of its kind. Exceptionally good early as f from 5.6 up to 2/3 of the field, only the extreme angles leave something 'to be desired at wide apertures but improve with decision af 8 eaf 11, where you will reach the maximum efficiency and a remarkable uniformity throughout the frame. ... "rnrnDa remember that this lens protrudes only 3 inches and weighs 180 grams, with filters of 49 mm! It 'was the lens I used more, whatever the occasion. rnMi is inevitable to think that today, to have the same angle of view on an APS-C camera, I have the dimensions and weight of a 14 or a zoom lens Samyang 10 -20, so it seems a big step back.
