David, I have the same inclination to mess with the focus whenever I zoom it to 35mm. Sometimes I think I can improve focus, sometimes I don't. Given the inconsistent nature of my observations, I've figured it was focusing error...on my part. <g>
Let us know what you find. Perhaps the lens can slip out of alignment over the years? Regards, Bob S. [EMAIL PROTECTED] writes: << Both you and Alan Chan state the same thing. I'm going to run a quick test with whatever film I have remaining in the LX right now (HP5) and see. In the viewfinder it looks like it goes a bit out of focus as I zoom out to 35 (after focusing at 105). I'm not sure whether this is reflected in the photos as the last time I was out using the Lens (with Jeff and Frank @ our August TOPDML get together) the images were still in focus after the fact. So.... I can live with the "it looks out of focus" in the viewfinder @ 35mm as long as the images remain sharp. I'll perform the test with the lens wide open at f3.5.

David, This lens is not varifocal. You should be able to focus at 105 and zoom to 35, all the while staying in focus... >>
