It is a great lens and it works quite well on the DSLRs too, my only criticism
is that its inherent geometric distortion ("moustache" barrel in the centre
tending to pin-cushion towards the edges) can make architectural shots look
pretty wonky (technical term). Fortunately when digitized the distortion can be
virtually negated using a re-mapping tool such as PTLens.
