Cosinon lenses are sold under other different labels as
f.e. Revuenon, Porst, Exakta, Via Brillant and Carenar a.s.o.., inspite the start aperture will be perhaps by approximately 3.0 - indicated 2.8. It doesn't matter. 
They are all 4/4-element constructions
++ very good center sharpness wide open
+++ Sharpness is excellent, especially at f 5.6-11 from center to midframe 
+/++ no remarkable center CAs
o/+ some few edge CAs wide open, disappearing nearly totally stopped down
++ high contrast
++ nice colors
highly recommended for this low price
75 LP/mm = 150 black and white lines per mm is a semi-professional value (with Fuji APS-C 24 MP-sensor)
same values for 24 and 28 and 50 mm Cosinons

| Pros: | sharp, lightweight | | Cons: | slower than other 2.8 | |
Got this one in mechanically bad condition together with an old camera body for almost no money.
Very small and lightweight for a 1335/2.8 but IMO also slower than my other 135 2.8 lenses. So effectively may be more something like f=3.2.
Gives nice sharp images, but I did not use it that much because aperture is broken in my copy and all in all I prefer the COSINON AUTO MC 135 2.8.

| Pros: | fast, sharp, good built quality, relatively compact | | Cons: | long max. focus distance, (no ‘A’ setting) | |
I got this lens together with an old camera and some other random lenses quite cheaply. So I definitely payed much less than this lens is worth.
It performs pretty good and its nice built quality make it a pleasure to use. Due to its wide apearture f/2.8 it is very nice for people photography!
taken with K5 at f/2.8, ISO 200.
