Originally posted by roy my main reason for not buying DA lenses.. eventually threre will be a FF. it'll probably have an option to shoot in aps-c format tho.
This is true. It would be a firmware tweak to extend use of APS-C scaled lenses to a FF sensor. If (when?) Pentax releases a FF, 35mm camera, I'm sure this would be a given feature to accomodate its growing DA line.
Having said that, you would still have the limited visual real estate and would likely use the lens less than FF lenses, at least I know I would. I've resisted the DAs for this reason. There are a lot of FF lens options out there for Pentax, perhaps its worth looking into these instead.
