So, now I have inexplicable urges to get more Zeiss stuff (Zeiss acquisition syndrome). I already have a very nice Super Ikonta BX with a meter that's even accurate, and it has a coated Tessar in Synchro-Compur shutter - all the good stuff. The lens is amazingly sharp, even wide open. Now I'm thinking about the III. Why the III? Looking at online auctions, it seems that the IV gets all the attention. I'm not sure why, as it has the EV shutter/aperture system, and the selenium meter. The III is basically the IV without the two features that are most likely to be annoying: i.e. the EVS interlock, and meter. The BX is beautiful, but heavy. But what advantage would I really have in getting a III to go with my BX? Just lighter weight? Before someone mentions it, yes I also have a Super Ikonta C, so I do have the ability to make 6x9 images too. So guys, please talk me out of spending more money on getting a III when I've already got a nice BX. Thanks.
