My Sigma 150-500 (K mount) and Pentax K5 IIS are satisfying. I was just curious as to when the pixel shift technology is going to perform as a feature. If the pixel shift technology performs on a tripod shoot in a scene at 200 shutter speed of a mountain or if it would work at 1000 shutter speed shooting a flying bird is basically the question I am posing. If it would not operate at 1000 shutter speed is a true characteristic of the pixel shift technology, then it does not. Obviously tripod only shooting only is not my only goal if I want to shoot handheld. If the feature is not going to be intended for handheld action shooting when a user is using proper settings otherwise, and/or it is limited to a tripod user as has been stated, then it would only perform in that way. I did not see it as being effective in only certain situations, when I first read about it I assumed I could look forward to possibly higher resolution levels because of it during any type of normal shooting.

Originally posted by stevebrot Both pixel shift and the in-body SR use the same mechanism, but they are not the same thing. Until the camera is actually released into the hands of reviewers, I don't know that it is possible to say what state the camera will be in when pixel shift is in use.
All that being said, my understanding is that pixel shift is intended for on-tripod use with both camera and subject stationary. Birds in flight would not be one of the intended applications.

Thank you Steve. That is the information I was looking for. Please note that my last post was done before I saw your answer (it was not referring to you). I agree also that until actual release of the camera and reviews, the specific performance of the pixel shift function and related information will be more available. I will be able to see any more specs I need most likely then.
