[QUOTE="semibovinian, post: 3037008, member: 76467"]Back in the days of film, I used to do coin photography with a Nikon camera. Of course, film coin photograhphy was a pain in the neck because of manual focusing difficulties at around f/8 with a blacked-out split-image focusing prism (and also no immediate feedback, no auto white balance, etc.) Around 1998, I stopped using film, and started scanning in coins -- the average scan at that time was better than all but the best film photos. (My modern scanner is terrible for coins, though). Around 2004 I got a Canon 10D and tried a few coin test shots, but focusing was even worse, with the crummy viewfinder screens (no split-image prism at all). You did get immediate feedback, though, which helped. And, no more film. I continued scanning coins before they went to SDB. Everything changed when I got a Canon T2i with tethering and magnified live view on the computer monitor. The resulting photos were so much better than the scans, and there was no longer any problem focusing. Also, by that time focus stacking software was commonplace, for closeup shots. I stopped scanning coins, and eventually had to reshoot everything. BTW, I used to do astrophotography with an H-alpha modified 30D, but thankfully I missed out on astro with film. TL;DR -- use a DSLR with tethering and liveview for focusing.[/QUOTE]
