Retreating to an earlier point in this thread, the reason I prefer a camera to a metallurgical scope for this sort of thing comes down to working distance.

My setup has an effective resolution of a couple microns at 5:1, which is more than good enough for most work, but also has a working distance of 40 mm (from the front of the lens to the plane of focus). In contrast most scopes are down to a few mm at most at that sort of resolution. I don't think I would have been able to capture the shots of Iwasaki float toothing that I recently posted on the forum-that-you-no-longer-frequent with a scope. At the very least it would have taken significant fixturing to place the plane of focus along one of the diagonal cross-channels, whereas moving the camera around the file was pretty simple (though admittedly I used a geared head and XY micrometer stages on top of that).

Note that camera magnifications and scope magnifications are very different things, because a camera at 1:1 is already heavily magnified compared to the human eye. My setup is probably equivalent to a high-quality scope at 100:1 or so.
