Canon's EF-S lenses don't mount on the 1.3x and 1x crop factor format
cameras.
That's my point.
Ah, I thought you meant in the Pentax model ... the DA lenses will
mount and function on any K mount body, but they won't cover the
format in all cases. FA and earlier lenses will all mount and cover
16x24mm format.
Canon EF-S lenses will only physically mount on EF-S compatible
bodies (300D, 20D, 350XT), EF lenses will mount on all bodies.
BTW: the Pentax DA14 will cover a 24x24mm format, max. I'm planning a
little project using it on the MX body, where it will be a fixed f/22
lens with 81x81x100 degree HxVxD field of view. That's sufficiently
more vertical FoV than a 20mm lens... Should be fun.
