I've had my IR converted K100ds for two years now and have been happy with it until recently. Last month I was shooting with the DA*50-135 and I started to notice that with tightly framed subjects (in the viewfinder) the resultant image was shifted to the left a bit (an annoying bit to be clear). I first thought this was me but as I'm seeing this now all the time, it's clearly the camera and I'm also noticing that the focus is soft as well. (I could post pictures of this but the difference is between the viewfinder and the image.) AFAIK this wasn't a problem until recently but I don't have any older images that I could compare with because I only use this camera from time to time. So I'm wondering if any one else has seen an issue like this with their IR camera.
I'll add that this camera was supposed to have the focus adjusted for IR. Most likely it's got to go back to the shop but I'd like to know if this is a known issue or just if I'm the lucky one...
