Thanks to all for the info. Looks like I'll be searching for the 60 mm. I have noticed that there have been a number of different versions of this lens produced. The early versions appear to have a extension/adapter that allows 1:1, and the later version (with the ROM) does not come with this adapter.

Is there any discernable optical performance difference between the early and late versions? To get 1:1 with the later ROM version, do you have to purchase that Macro Adapter?

I noticed in another post, mention of "window seals" requiring

replacement on the R4 bodies.

I looked at mine, and all the foam light seals are

noticably "sticky". How do I go about getting these replaced and who

can do this?

I have an R4 body and the 90 mm Summicron-R F2 tele lens. I would

like to get a macro focus capability, and would like some input as

the most cost effective way to do this.

So far, I could

(1) purchase a Bellows -R and use my 90 mm lens

(2) purchase a macro lens like the 60 mm Macro Elmarit-R 2.8

(3) purchase the Macro Adapter R and use with my 90 mm lens

Which option would give the most flexibility? The bellows and macro

adapter seem to be the cheapest (about $200 used), but I am not sure

what focus/magnification I would get with the Macro Adapter and the

90 mm. The Adapter allows normal aperture metering (does not require

stopping down the lens for metering), whereas the bellows does not.I

also have a 180 mm F2.8 which I could use as well. Will I loose

aperture speed with the bellows and Macro Adapter?

However, since I don't have a "normal" lens (I have 35 mm and 90 mm

F2s), the 60mm would provide some capability at a much higher cost.

Any other options? Thanks in advance for any input.
