No problem.
I misread your post

I am selling an excellent SMC M pentax 50/1.7
pm me if you are interested

I found the problem.
The new CS6 has new default preference for image interpolation.
In CS5 the interpolation method is Bicubic(best for smooth gradients), but in the new CS6 it is set to Bicubic automatic. This was causing the problem for me. I went to Preferences -> General -> Interpolation method Bicubic(best for smooth gradients) and all is fine now.

This automatic bicubic interpolation just don't work for me. Here is an example for just resized pictures, on the left is with automatic(default) and the one in the right is with Bicubic(best for smooth gradients).



The default method for CS6 tends to create this 'over sharp' effect by using that automatic interpolation, which just looks like CRAP.

Still RC is better than beta

Hi there...
someone have it and don't use it?

offers considered!
I have two 50's so i should get rid of one

week end bump

RC-Release Candidate means not official.. which means that they won't seed it through the update channel until it goes "final".
RC is still good to use as it's not beta and doesn't have unknown bugs and issues like alfas and betas.

In very good condition.
All works well.
I cannot see fungus so i assume there aren't any.
Comes with no name uv filter, back cap and i will check if the front cap is OK.
