I realize this will vary from lens to lens, but what is the median size of 
the projected image circle on the Pentax lenses you are familiar with? I 
suppose one should take the smallest value if the projection changes size 
with aperture.
My reason for asking is that I think it would be nice if the shake reduction 
technology could be assimilated into a 24x36mm DSLR, but I've always been of 
the impression that most 35mm camera lenses don't offer much coverage beyond 
the 35mm frame. It's what I was taught when I was learning the nuts and 
bolts of photographic theory.
