Everyone seems to be concerned about Bokue with lots of discussion, but I see very little about how well dof is handled and how well the camera resolves at infinite. I see lots of images of landscapes where the trees in the distance have turned to mush! Let have some discussion on resolution at infinity. So far my D800E with a 24mm F1.8G seems to do a reasonable job, but is there anything in a compact camera that works well with good atmosperics?
I'm guessing you mean the 28 1.8G? If so, when I owned that lens and the D800E, I ran a few tests against the Sigma DP1M (which is similar with regard to focal length) and the results were surprising with the DP1M actually outperforming the Nikon D800E+28 1.8G in some areas of the frame. Part of this was down to the 28 1.8G which seemed to have some field curvature when focused at infinity. Given that experience, I think the only current compact camera to suggest would be one of the Sigma DP Merrills - and the DP1M if you need a wide angle. Both of these Sigma's will outperform the RX1 at base ISO, particularly when used for landscape type subject matter.
Tariq, do you have any side by side comparison shots at different distances and apertures between RX1 and DP1M to back up that statement?
Also not all landscape is done at infinity focus.
Just addressing the question of the OP, which was specifically about infinity performance.
No, I don't have tests with the RX1. That said, it does not seem at all likely - and there would be no reason to believe - that the RX1 would be capable of outperforming the D800E, even with the Nikkor 28 1.8G (which is no slouch stopped down between 5.6 and F8). Therefore, it would seem to follow that the DP1M, if capable of at least matching that performance (D800E+28 1.8G), would likewise outperform the RX1. Nothing against the RX1, which would be a much more versatile camera overall than the Sigma DP's.
