>>>Are there any limitations of the lens mount? Of course there are limitaions to the K mount. One of my least favorite is the loss of auto apeture when using M42 lenses... It's design is based on covering a 24x36mm piece of film. There's no reason to design a lens mount for a digital camera for this specific size frame - other than to retain the same relative magnification when using existing 35mm lenses. I would happily accept a 1.6 magnification factor on my existing lenses for the ability to use a F1.8-2.4 24-90 (35mm equiv.) zoom or an F2.8 600mm - this is something that becomes much more of a possibility when you only need to cover a smaller than 24x36 digital sensor... All of your lens designs get smaller and lighter, too... >>>>...This system will feature an entirely electronic, all-new lens mount. I agree that jumping on this band wagon might be a good idea for Pentax but I can't see why it should exclude digital solutions for the K-mount. That would be shooting themselves in the foot. Psl >>>>>> It doesn't exclude K mount at all. My fantasy Pentax digital camera mount retains complete backward compatability (except for magnification factor) with all existing Pentax lenses - including M42 - by using a much shorter back focus and electromechanical adapters. I agree the engineering would be difficult but not nearly impossible - it's also a much easier task with an electronic lens mount (on the camera side)... Finally, auto apeture (without my spotmatic) with my M42 lenses! And a "digital solution for the K-mount" Yep - I want a new Pentax digital camera mount to make using my favorite Super Takumars easier....Hey I'll NEVER give up my film based cameras - I'll use my K mount and M42 wides on my old Super Program...
