I find it interesting (for my Protracted argument) that Leica went with front
close up glass instead of rear tubes like all the other companies did as the
attachment to bring their 100 2.8 apo macro from 1:2 to 1:1!
On the long run a macro specialist would be doing it to thier macro glass from
both ends!
Plus a bellows.
Why don't i have a bellows by now? I'm a big boy!!!! Full enough of hot air maybe?
Now that I'm getting a Viso (from Dan Post) the bellows could be an obvious soon
to come thing!
