Hello, I have just recently got back into serious photography and purchased a K3 with an 18-135mm.
I also have just also bought a smc M 1:4 200mm lens off ebay that is in perfect condition inside and out visually, I was so happy it was pristine looking.
Oh dear, then i took some pics and the quality is very poor. I tried all the apertures, fast shutter speeds, very careful support and squeezing the button, for not pretty results.
Anyone that thinks they may know the problem, I'd like to hear from?
Hopefully I have attached 2 sample pics, but this is a first attempt
Thanks for looking
Carl
