Originally posted by AfterPentax Mark II Well this certainly points you in the direction of a bad contact between lens and camera. By mounting and dismounting you probably clean the contact a little bit, just enough to work for a short time. This sometimes happens and I had it once with my K-7, a thorough cleaning of the contacts and the problem was solved. As for the remote control I never use it, but with the KP you could try to fire the shutter by the use of a smart phone and a program called image sync I believe. It could be that the remote control that seems not work as it should is causing the problems.
And as said before by Wadge22, when using a tripod turn the SR off. It can cause problems if you don't and it is one the problems that Ricoh warns you for in their manual.
Hope this helps.
It has nothing to do with the SR, but thanks for the input. The SR would possibly give a soft image due to constant correction; this goes way beyond such an issue. This is a massive out of focus image. if you look at the images I post of my camera collection, you will see nothing, but studio shot images up to 20 second exposures. The lens will not correct its focus, because it is in a controlled environment with nothing to correct against. Just because you are mounted on a tripod does not indicated SR should be shut off. That is an issue of time and condition. I completely understand the concept, and I can assure you the issues I am now experiencing have nothing to do with SR. Thank you for the input, it truly is appreciated.
