I noticed a couple of dealers have a pretty good deal on the IIIf classic camera, the mini-Leica. Some questions on it: 1) Is it fixed aperture? If so, does this mean you need to use 25- speed film? (IE, sunny-16 rule with f/5.6 and 1/250 works out to 25- 50 speed) 2) It appears that some or all of the Minox film is Agfa products- any guesses as to whether this will still be available for any time? 3) Seems like they've made several of these mini-classic cameras, but I'm not seeing much on ebay. Did the other models sell well, or were they flops? Any guesses on reliability? 4) Do any of you routinely use this or other 8x11 cameras? Or are they more in the gadget-on-a-shelf category? 5) I don't see much info on the film cartridges used. Are they like a mini-35mm cartridge? Are they reusable if you slit your own film? And does anyone actually do this? 6) I noticed a Beseler minox negative carrier on Ebay- are these things rare as hen's teeth, or do they show up pretty regularly? 7) Looks like Minox lab processing is available by mail order- how is the quality? Thanks!
