I love my Comby dearly, but it does show considerable 
pincushioning, at least to my eyes now. I was oblivious to this 
until a friend mentioned that the STL 2x2x2 viewer of German 
make, shown at the spring Kansai club meeting here, is 
relatively free from this distortion. This viewer seemed much 
less ergonomic to me (but the two slide holders can be 
individually rotated), needs adapting to work with Realist 
mounts, and lists for 80,000 yen (~$750) in Japan. Japanese 
prices are often ridiculously high for specialist equipment, but 
the lenses are very fine. FWIW, I now see pincushioning in 
Realist viewers if I look, but usually I'm too absorbed in the 
views to notice or be bothered.
