All these shots were in jpg, without any PP, provides a good contrast, but I read that some copies have some problems to get focus, in my case I found regular in fact was a very quick review, the focus ring feels very smooth but the body very heavy, heavier than the camera itself.

The first thing I noticed is that the Vivitar 28mm/2.8 and the 2.5 have very LARGE front glass elements - compared to most 28mm primes I know of!
The front glass element of those Vivitars are even bigger than the Yashinon 50mm/1.7 so I mistook them for 50mm/1.4 lenses...

yeah, you're right, although at first glance appears to be identical, some very small variations among them, besides being both too heavy, not bad.
