So, what does Canon have to offer that might be a reason to change? IS & USM. If you need/wants quiet af and is on your long lenses, that may justify a change. 888888888888888888888888888888888888888888888888888888888 I think that canon offers more high end lenses than Pentax does and there are more possible optical designs with the EOS lensmount specification, it is a much larger throat....
They also are a few years ahead of pentax in DSLR development, which is an asset if your cosidering one of those bodies....They are already in the 3rd or 4th generation bodies. 888888888888888888888888888888888888888888888888888888888 What might Nikon have to offer a person to change? More-solid PJ-grade bodies. If one needs/wants this then there would be cause to change. 88888888888888888888888888888888888888888888888888888888888 If I had to start from scratch, I would probably go with EOS mount over Nikon. EOS was/is more capable and Canon/Nikon are both pretty capable in terms of the optics. This brings up an interesting question. NIKON has offered reasonably affordable DSLRs for a few years. DID THEY abandon basic features of their earlier F mount lenses for zero technical reasons or improvements like Pentax has just done with the ist D when they introduced their DSLRs? I doubt it. 88888888888888888888888888888888888888888888888888888888888 What does Pentax have to offer? Best optics. Limited, FA*. Pretty much all in the shorter focal lengths. (Nikon users might argue some specifics, but the whole range of Pentax optics, both current and past, are clearly outstanding.) If this is what one needs/wants, Pentax is a consideration. 888888888888888888888888888888888888888888888888888888888888888888 While Pentax certainly makes some very fine optics and has for a long time, I beleive that Canon and Nikon are both committed to and have been producing some very fine optics also. Pentax does not have any real advantage in this dept. as far as I am concerned. Yes, the older KM lenses were and are fantastic quality and for pentax to discontinue support of these fine lenses for no technical reason or improvement is absurd if they are not changing the mount. I contend any camera that doesnt support basic aperture sensing of K/M lenses is not a KMOUNT camera. If it is no longer KMOUNT, why??? OMISSION, no technical or economic reasons as that has been proven in very cheap (ala k1000) film SLRS.
