I have this scheme. I'm attempting to replace my expensive cameras w/ cheap ones, w/o giving up image quality. So far so good, and my next step in the process is to replace the Super Ikonta III w/ Novar w/ a simple Zeiss Ikon Nettar. This one ran all of $20, shipped, and has a very different lens. It's an uncoated Novar 75 6.3 Anastigmat in a Klio shutter. When I got it the shutter was DOA and the lens was super cloudy. I took it apart, cleaned up the elements (tiny!), flushed the shutter w/ lighter fluid, cleaned up the blades w/ Q-tips, and its fine now. Getting the rear element out was tricky, as it was held in with a simple wire C clip which promptly popped out into the air when I was removing it. Took me an hour to find it, and it had been lying on the couch not 2 feet from me all that time. The camera is limited by the simple shutter that tops out at 1/200 (an actual 1/150). In bright sun w/ Tri-X and a yellow filter it was stopped down all the way, but in less light I was able to open it up a little. Turns out no matter where the aperture is set it's crazy sharp. I had to back off on the sharpness quite a bit in PS. It's a little too contrasty for my tastes too, which is pretty strange for an uncoated lens. The Nettar is much lighter than the Super Ikonta, but I like the IQ of the Super better. Still, this Nettar may be a keeper because it does such a good job. One thing that puzzles me is the aperture settings. If I set it wide open (f6.3) it looks fine, but if it's set to f22 it isn't stopped down all the way. You can actually push the selector way past f22 and the lens will continue to stop down. So I have no idea where f22 really is, and if someone has any ideas I'd be grateful to hear them. Here's my day in New Smyrna Beach w/ the Nettar and Tri-X, and a yellow filter and hood. At home, it was souped in D76 full strength at 70 degrees for 6 1/2 minutes.
