Regarding MTK's 7D question, from above:
The second one I purchased, as a pre-owned item from a local camera store, tends to front-focus with most lenses. With my 100L Macro IS, however, it works fine, and so that combination remains together almost all the time. As I acquired the second 7D to minimize changing lenses while at work, anyway, and the 100mm is my most-used lens, this is not a problem; I have not bothered to try micro-focus adjustment with other lenses.
I have, thus far, been unable to get firmware updates to work, but that is probably a reflection of my quite shallow understanding of computers. I cannot blame the cameras for that.
The 7D is certainly sturdy, certainly much tougher than a original "Classic" 5D, though "tank" is probably a better description of the 1D-series. On that subject, I just won the bidding on a 1D Mark IIN, which appeared very clean in the auction photos, and is supposed to have a very low shutter count. I am awaiting its arrival. I will probably order a battery for it Monday, as I doubt the originai will still
perform optimally. This will give me sufficient MP for my work photos, a very high level of weathersealing, and a second memory card slot, for instant back-up. The APS-H sensor will be a compromise in size, between full-frame and APS-C. It should be interesting!
