Has digital camera development hit the wall?

Tom, To be honest the GXR is feeling dated. It has indeed hit a wall simply by the fact that it is an older sensor. To supplement the GXR and GRD I bought a Pentax K30 and a kit lens (it's my family snapshot, "soccer dad" camera). That sensor is better in all the right ways. The A12 units still work fine of course, but they could work just a little better, and I'd be a lot happier.

That said, I just bought a new GXR body because one of mine broke and the screen on the other one is all scratched up. I'm not giving up yet. Presumably, any new units can be used on the current body. I also want to see a new body with built-in EVF, though.

I'm pretty much done with the Mount unit. I have trouble focusing accurately and it's just easier for me to use the A12s. I may sell it and the Leica 28mm lens. I know some believe that the Mount unit is the best GXR unit and is what really makes it a viable camera, but IMO that's not true. The A12 50mm is a gem and the A12 28mm is very, very good.

Besides the K30 I'll wait to see if and what Ricoh does next. Their silence is odd - either show that you are at least working on something or state that you are done.

But no, digital cameras have not hit a wall - Ricoh has.

* At least the K30 is still in the Ricoh family And it's a great camera, and it's nice to have an OVF again.
