i'm kinda annoyed by how large the diameter is on the 58/1.4 shell that my 45mm is in though, so i might switch it to a 55/1.7 as well

I wonder if the 55/3.5 macro would work for the 90...

it might, i like the 55/1.7 though because it's narrower than all the 55mm filter thread rokkors. i'm not terribly excited yet about having the 90g either to be honest.
I was thinking it might be great for close focusing whith the macro helicoid, I don't know if IQ will hold up at those distances.
the 45mm will have a longer spacer between the mount so they'd be easy to tell apart. i like the idea of two identical handling lenses though.

I haven't made it to the machine shop to make the spacers yet, but I can post pictures of the lens disassembly if you'd like?
Sebboh,
I'd love to get a look at the disassembled lens (so far I've only found pics of the left-over parts but not the optics/aperture group itself) and maybe some measurements needed for transplanting it to the donor body. I've been playing with the idea of "frankensteining" a 45/2 or 28/2.8 (or, ultimately, both) for some time, and getting an idea of the necessary work in advance would be very nice.

i'll post a how to with pics for disassembling the contax g 28/2.8 and rokkor 55/1.7 showing how the two can be mated. the 45/2 disassembly is pretty much the same.
it'll probably be over the weekend though, i'm rather busy today.

Anything you care to share will be greatly appreciated.
Are you using a lathe to turn a spacer or some other method?

Just got a Nikkor 55/1.2 AI. It seems way sharper wide open than the 50/1.2 and also better than the older 55/1.2 pre-AI. I guess they had to do some compromises when shortening the focal lenght, due to Nikons large flange-to-film distance. So this might be the best of the bunch, except for the Noct-Nikkor 58/1.2 of course.

I did have a spanner wrench, so i used two small screwdrivers . I started from the rear removing each retaining ring and glass element. The rings were not real tight. The last final element didnt seem to have a slotted retaining ring- that glass i broke out. I never had to dissamble any part of the front or rear lens mount.

Hmm, I am finally getting around to this, and mine appears to be different than yours. The rear element had a retaining ring, but after that there are no more visible retaining rings front or rear. I guess I will have to remove the bayonets and see what else I can find.

I was wrong. The next element had a spacer ring which was not fastened, and with a bit of jiggling, it just fell out. Then there was another retaining ring, and then another spacer and another element which fell out. Now the only one which is left is the one at the very tip, and it looks like it should unscrew, but I don't have the right tool for this. I am considering ordering it...

Old Sigma Apo Macro 180/2.8 1:2 -1,35kg and 82mm filter thread.This beast is all manual (Contax/Y mount).Basing on my current experience with it's smaller sister Sigma Apo Macro 180/5.6,which is a very good lens,I think I should be pleased with it.

I finally managed to find a Zeiss ZF.2 85/1.4 for a reasonable price, and I am impatiently awaiting it now.
It arrived, and is generally in really nice shape, but unfortunately there is a small scuff on the front element (and some sticky residue on the focus ring, which I can easily clean). I wrote a nice email to the seller, but since I got lucky on the price, his attitude is basically that I can send it back if I want. I had to wait a long time to get a decent price on one of these, so I am inclined to keep it, though. Sigh.

I haven't bought any new lenses in quite sometime, however I think I am getting the bug again. Of course at this time I have a NEX5 and A850, and am thinking about converting to only one system or the other. Its tough for me, because both systems have the pros and cons. I am leaning towards the NEX - with the eventual aim of purchasing a 5n, 6, or 7.

Voigtlander Nokton 58/1.4 SL II-I'm curious how good (or bad ?) it is versus Z series Planars - 50/1.4 and 50/2 Makro,plus the rest of my 45-50-60mm stable.
