All true. And ideally the camera would know what the 'right' crop is for each lens and do so automagically, (in green mode anyway). But I don't believe any other camera maker does that, please correct me if I'm wrong, so I think it will most likely be a 'safe' crop that makes sure all DA lenses will work as expected. I think the option to NOT crop would be great, I'm not so sure Ricoh will take the risk of getting bad press/comments on a camera that takes vignetted pictures. Not everyone has the experience to know what is going on, and those who don't are often the most vocal.

But we are speculating on possible features or non-features of a purely speculative camera..............
{Edit: I think I was wrong 10:55pm] Actually I think they can and do crop specific chipped lenses just as they process specific Lens Corrections based on the lens identifier.

The same argument about risking bad press could be made about AF Fine Adjustments. They are an example where incautious use will results in consistently bad images. But they are provided.

I did not know that. So different pictures would be cropped to different sizes depending on the lens used?

Also true. Although in this case you actually have to DO something to mess things up, not just put a DA lens on a FF camera.
I guess we will find out what Ricoh thinks about this if/when they ever build a camera that requires us to worry about it...........

I was curious so I read around a bit. Actually I think I was wrong. When in Auto crop mode a Nikon FX camera will recognize a DX lens and use only the center portion of the sensor. It would make sense for a camera where the algo has programmed lens corrections in place to use as much of the sensor as possible (eliminating vignetting) but I don't think they do that.

I thought Nikon autmomatically crops DX lens when on a FX body.
This is true. However, automatic crop can be turned off on the D800, and a 1.2 crop mode is available too, along with a 5:4 aspect ratio.

Well. If one had dinner with the Pentax Rep tonight and looked at the new toys this coming holiday season. One would be be "full" of quick expectations if you are a Pentax DSLR user. One would not let go of K ff lenses very quickly. Read between the lines. Of course One may have been "spot on" with the timeline of the 645D , but what was is is ?
Look's like 2014 will be a full year from now, even though it was "Fully" seen with a K-3 proto late summer. Damm they have it but won't produce it. From what I understand there was more of a need for processing speed @ a half frame per second more. Probably the K-3 II df. If anyone wants to sell their F series lenses I'm still buying big time. Just not the 35-80mm LOL.
