Not really. Lots of K-mount lenses can be found many places... Regards Jens Bladt http://www.jensbladt.dk +45 56 63 77 11 +45 23 43 85 77 Skype: jensbladt248

As much as it is a nice feature, it's mostly irrelevant if you don't already own a lot of older Pentax lenses. When I bought my DS, I bought a bunch of A and M series lenses to figure out what I really wanted. One by one, I've sold them off as I bought the current, latest series lens in the focal lengths I wanted. You only get all the features of the body with the latest series lenses (F, FA, DA) and I didn't see anything so special about, say, the A50/1.4 that the FA50/1.4 doesn't provide, and the FA model provides more. I can see buying older lenses like this as a way to get a good lens that you can't afford a new one of, but overall the new lenses in the latest series outperform the older ones. > A member with a Canon 20D said "Oh, Canon's can do that too".

It works with an adapter, if you can find one. You need an adapter to fit M42 lenses to the Pentax DSLRs too. So Pentax direct lens compatibility goes back to 1971 where Canon goes back to 1984 or something like that. A good thing is that the Pentax adapters are easy to find and do not need to have any optics in them. But there's no point ... Better to think of it that the EF series EOS lenses fit all the EOS series Canons, the FD series do not, and the EF series lenses provide all functions on all EOS series bodies. The FL/FD series lenses fit the Canon FL/FD bodies. Canon switched over 22 years ago or something like that. Canon owners with a big investment in FL/FD lenses whine about it all the time still. The only 'hiccup' in Canon EOS lens compatibility is the introduction of EF-S series lenses for the small sensor bodies. For whatever it's worth, the lens mount change was one of the things that gave Canon an advantage in their body designs since. The EOS mount is larger and wider, allowing more freedom in optical design, and has state of the art camera to lens communications couplings.
