I feel the selenium meter adds a noticeable amount of weight, and so I leave my IIIA on the shelf while I use the IIA and a handheld meter.

It took me only a few minutes to get used to the Zeiss Ikon Contax, and I love the camera, love the lenses and love the results.

I like the IIA better than the II, simply because it's a smaller camera.

As for an odor, that sounds like some other issue. Zeiss Ikon cameras have no untoward odors, aside from what happens with leather.
