Pros: Colors. Almost non-existent distortion. Sharp from f5.6 up

Cons: Full opening not sharp

Opinion: What can I say? Considering age, it's a wonderful view. the absence of distortions or almost has incredible. The colors are full, saturated without ever being excessive. Great reading in the shaded areas.. and it's no small thing. Very good sharpness,but from F5.6 onwards. At full opening F2.8 is very soft especially you have edges. A slight vintage flavor, but not too much. I use it with satisfaction on Sony 7R and it gives beautiful images, with a slight vignetting, easily corrected, but which is sometimes pleasant. He suffers a little backlight, but given his age, I don't think we should be so demanding. The blurry is pleasant, it is not kneaded like many current wide angles. It is not very cheap, it can be found around 300 euros, but it is money well spent. N.B. M49 screw attack

Pros: Exceptional lens, very distorted, little light falling to the edges, sharp. Last but not least, M42 screw adapters cost very little and are good.

Cons: If we really want, the impossibility of using all the digital camera cameras. Pretty complicated to repair, if needed (sooner or later you will need to clean the diaphragm blades, do not run away, unfortunately).

Opinion: A lens you can no longer do when you buy it. Even second-hand is not economical, but you will soon notice superior quality both in the lens itself and in the results it can achieve. It offers excellent sharpness across the framed field and almost three-dimensional spatiality, color rendering is very well balanced. Anti-reflection treatment is good for the time when it was produced but absolutely not very excellent, so when shooting it is necessary to use the appropriate methods to avoid unwanted reflexes and unwanted hairs.
