I couldn't come anywhere close to yours hand-held at 200mm. Smears all over - even at 1/1000 hand held. How do you do it?
Is there that much of a difference between a Fotodiox MD adapter I used, and the $250 pentax K one?
For hand held shots yes, I believe the Pentax adapter does make a big difference, try the same lens with a tripod first. From what I understand the electronic shutter on the Q and Q7 takes 1/13 of a sec. to capture all the lines in an image even at 1/1000 sec. The camera captures the first line at 1/1000 sec then saves it, then captures the 2nd line and saves it the save takes the time the process takes 1/13 sec to capture the image. If something moves during the 1/13 exposure camera or subject the lines do not line up
With a shutter in the adapter the entire image is captured then saved
Remember I only get about 25% keepers hand held at 200mm
