One more question
I still in my bag several older style Russian lenses
I used before with K-20/ manual/
But what about k-3?

I also use a number of manual lenses with my K-3 and K-5II. Works like a charm. In order to facilitate manual focus I substituted the custom focus screen for a Canon S-type from Focusingscreen.com (plane, no markings), but that is not a must.
