Hi Doug
Both photos are amazing – superb quality all round.
It looks like the non extender version has very slight coma at the extreme corners, and did I see evidence of mirror slap in the full size x1.4 extender version? The full size version looks as if it has some (very) faint double stars reminiscent of what I used to get without mirror lock up?
Great side-by-side results though and I had to pixel peep the full sized versions to notice the above stuff.
Cheers
Dennis
