Same lens. It's farther away from the sensor (and mirror), so interiors 
for OCT18 lenses are not a problem.

A lot of light was creeping in. I took the same pic a minute later with 
the Canon lens and it was pretty dark - looked like it was a good 3 
stops under. If you want, I can post a few more photos from then as well.

Interesting. An adjustable mount would basically do the same thing as 
the focus wings. But could it be as accurate? Hmmm.
