A couple of quick notes:

• A fellow enthusiast tells me that his M6 half case won't fit the Zeiss Ikon.
• The dimensions of this camera are very close to the Zeiss Ikon Contax II from the 1930s. The prewar Contax is a really great camera with a huge 90mm rangefinder base (the Zeiss Ikon's is 75mm, effective 55.9). The rangefinder is so wide that coupled with the infinity lock, you need to develop the "Contax grip" so you don't block the rangefinder window.
• I was thinking of my own torture test: Put the camera into a light padded bag and kick it down the stairs. Yeah, I think I'll hold off on that one until I can test it with someone else's camera.
• These are slotted lens shades, but as expected they do intrude in the lower right corner of the viewfinder. You don't lose much with the 50mm Planar, but it causes problems when trying to frame with the 25mm Biogon. This might be another reason to go with an external viewfinder. In the shot below, keep one thing in mind: There is no vignetting in the real viewfinder. This simply is not being able to get the digicam close enough to the eyepiece. The view through the finder is very bright, and there is no corner shading.

The shot above is with the 50mm Planar mounted. The 50mm Planar and 25mm Biogon are roughly the same length from mount to shade bayonet. If you consider that the view for the 25mm Biogon is roughly the entire frame, you can see why an external viewfinder is the best option for this lens. And you can also understand why the finder is recommended for both the 25mm and 28mm lenses. In many cases, the loss of the lower right corner of the viewfinder isn't an issue. However, with verticals, it became a bit trickier.

• I'm not a big fan of the offset tripod mount. I think Zeiss could have moved the mount closer to the center. However, that idea would have required a spacer of some type. Maybe Zeiss could have revived the Contax foot. Or maybe not. With a little work, I think this camera could have been fitted with a motor drive, and possibly still can.

I rescanned many of the Agfapan APX 100 shots. I batch-scanned all 72 shots, but I wasn't satisfied with the quality in many of them. So I went back and re-scanned a good number of them. Also, the scanner's auto-framing process severely cropped all of the shots.

I'm going to try to get in a bit early and do some shooting on Pittsburgh's North Side – another old community that has its ups and downs. Wish it wasn't quite so cold right now.
