I challenge the assertions above, that (1) technique and (2) quality of lenses are that much of an issue.
Firstly, while the technique used to keep your lens stable will always be an issue, and probably more so in a camera with such a high resolution, the effective
resolution of this camera is little different to that of a Nikon D7000, and less than that of a Canon D60/7D, given that they use cropped sensors, especially when using a lens with a similar focal length.
Secondly, and taking into account the use of a lens with a similar focal length on each of a DX and FX camera, you will get a much wider perspective in the FX-captured image. As such, should you wish to have a similar image perspective from an FX camera as you get from a DX camera, you would either need a lens with a focal length of 1,5x (or in canon's case, 1,6x) on the FX camera, or crop to DX size (a bit of a waste of all those pixels
Thirdly, lenses to resolve a 16mp image in DX in the case of the Nikon D7000, or an 18mp image for the canon D60/7D seem not to have been an issue to date. Why then, should resolving a 36mp image on a full-frame sensor, which does have a similar pixel size and
improved light-capturing ability, cause additional concerns with the quality of the lenses used?
Note that three of the major benefits of a high-resolution sensor are the ability to:
- print bigger pictures (I would suggest that few would really exploit this benefit to the full);
- crop further than would otherwise be the case;
- down-sample pictures to final output size required and in-so-doing, resolve many other issues that cannot be achieved as successfully with an image from a lower resolution camera.
This does not imply that there are no disadvantages to high-resolution cameras, but I would still like to have the opportunity of exploiting the benefits of a D800 to the maximum.... Pity the bank manager says NO!
