Interesting. I wonder if anyone else has observed this and can verify.

Among other things, optical configurations are a weakness for me. So
let me ask this: the spot would be more prominent because of the larger
film coverage, right? 35mm film would probably show only the hot spot
area. Feel free to slap me around on this, it's how I learn. :-)

Statements like the one above lead me to attempt to find out more
before I look away from the 106 FSQ. It sounds alsmost perfect except
for the damn hot spot. However, I use Supra color negative in a 35mm
format, so that might possibly make things workable from my point of
view. What do you think?

Thanks for all the input so far, both here and off-list.
Alan
