Macro in the Leica World

[uskanb2n@ibmmail.com]

I would appreciate it if folks would comment on the various lenses used
for Macro & copy work in the Leica system. I have a M-2 with in addition
to the usual 21, 35, 50 & 90mm lenses, a Visoflex II and bellows and a
Leicaflex SL with 35 & 180mm lenses

The only remnant of my Nikon outfit is an F body and a 55mm:2.8 Micro
Nikkor, the only Nikon lens I have owned which has been really
satisfactory. The only thing is this is another heavy body to carry
around for a limited use.

I have been told that the Visoflex is preferable for copy work over the
Leicaflex & R series due to being a 100% view focusing screen.

I have an adapter for the 90:2.8 & 65:3.5 lenses for the bellows, Is
there one for the old style 90:2 Summicron? If there was would the lens
be any good for copy work? Which 90:2.8 are they talking about on this
adapter & would it be a good copy lens?

I do both a fair amount of both copy work and field work: copying flat
art for my wife and a couple of friends and photographing botanical
details with the macro lens as semi-abstract images... I rarely go
close enough to want an extension ring on the Micro Nikkor.

What are the differences among the versions of the 60:2.8R? Do they
focus as close as the Nikkor (1:2) before resorting to extension tubes?

Thank you for wading through my ramblings,
