Having made the fatal mistake of holding one, I may be the proud owner of an EOS-1D Mark II N next week.
Apart from the banding issue at high ISOs when combined with AI servo, and potential autofocus mis-calibration, are there any other issues I should be aware of, or look for, when testing the body in-store?
Also, are non-Canon batteries a safe option? The original is around AUD 300, while I can get a similarly specced afterm-market one for almost a tenth of the price. Do you know of any reputables brands/sites to buy them from?
Thanks, folks
