I have a Rokkor X version that I think Jim converted prior to my buying it, it looks to be in better condition than mine.
I used to have the 35/1.8 before I lost it.

Lenses for the test continue coming in.

Tamron SP180/2.5 LD-IF
Vernon 180/3.5 Edonar

previously purchased:
Leica 180/3.4 APO-Telyt-R
Nikon 180/2.8 ED AI-s

SMC Pentax-A 28mm F2
Summicron 50mm

Much getting-to-know time over the weekend is planned.

Minolta 100mm f2.0 AF
Minolta 28mm f2.0 AF

Rollei Distagon HFT 35/2.8.

Yasterday I received Rollei-NEX adapter and did quick comparison test of Planar 50/1.7 C/Y versus recently acquired Rollei Planar 50/1.8 HFT.The IQ differences are insignificant.w/o Planar C/Y has very slightly less CA and veiling.Stopped down it is tiny bit contrastier.Rollei OTOH has closer mfd - 45cm vs 60cm.

Rollei lenses with Zeiss brand names are in fact as good as C/Y Zeisses but 40-60% cheaper (my mint- Planar cost me 49 Euro+shipment).This encouraged me to try Distagon 35/2.8,which I expect to be as good as Distagon 35/2.8 C/Y that I got.

White the optical part of the Rolleis are often as good, or close, at least some of the lenses have inferior aperture blade counts, down to an amazing minimum of three, so unless you shoot wide open all the time, you may get some undesirable boke characteristics.

I bet you could have got the Flektogon's working perfectly. They are very simple to disassemble. My blades were sticking occasionally, a good clean, and mine is now flawless.

Usually you can't lose pulling them apart and seeing whether it is possible to clean them.

Yes,but I think classic Zeiss constructions like Planars,Distagons,Tele-Tessars and Sonnars have similar number of the aperture blades.I don't remeber how it goes with Mamiya made Rolleinars but it's easy to find.

My HFT 50/1.8 Planar has 6 blades like C/Y 50/1.7 and very similar (not so pleasing) bokeh.Here is shot w/o on the NEX5N:

You're right.They are mechanically simple,but being impatient and not very handy at tools I'm usually avoiding home fixing.

Picked up a Nikkor 24/2.8 AI-S today, along with a new Canon 50/1.8 II. Both are alt for this NEX shooter.

First lens acquisitions in months actually, and paid for by the sale of the last, a Nikkor 85/3.5DX VR Micro I bought in September.

Picked up a P. Angenieux 135/2.5 Type P2 No 371xxx

Stumbled across three OM lenses in good shape yesterday:
50/3.5 macro
35-70/3.6
300/4.5

Now I just have to wait for the OM>NEX adapter to get here next week to shoot some test shots.

All of them are very decent.Maybe 300/4.5 lags a bit behind because of it's long mfd,CA and softness wo,but all in all nice purchase.

Yestarday I managed to buy MC W.Rokkor 28/2.8 - the last one to complete series of late MC Rokkors from 1973-1977 that I have.Now among other MD Rokkors/Plain MD lenses I enjoy 24/2.8 MC+28/2MC+28/2.8MC+35/1.8MC+35/2.8 MC+50/1.4 MC PG+85/1.7MC+135/2.8 MC+200/4MC - the best Rokkor series overall IMO.

Peire - Thanks for the information on the 300. I'm still looking for a few wide OMs and keeping my eyes open for fast Rokkors at decent prices.

Waiting for an Olympus Pen F 42mm f1.2 and a Pen F to XF adapter to come in!
I'm really excited/nervous to see how it preforms on the X-Pro1.

those weirdos in the distagon 35 1.4 thread really love that rollei

The crocodile shot was brilliant!

Reposting, by LeadyGonzales:

Yep - that sure is a great shot!

Ordered a Canon 6D today, I miss using my C/Y lenses (35/1.4, 50/1.7, 100/2, 135/2.8). I considered a used 5D2, but I recon the newer sensor is a tad better all over. Looking forward to it.

I think i have bought too much stuff last month

1. Minolta MD 24/2.8 (the 4th or 5th copy i will try, none of them could justify the legends minolta fans sing about this lens) 35/2.8 (i really liked the mc version but the friend who borrowed me his 5dII took it on his trip around the world), 135/2.8, MC 300/5.6 (i don't expect much but we will see, couldn't find any source about it, the Minolta 200/4 MC is quite sharp)
   
2. Canon FD 100-300/5.6, 50/1.8, 70-210/4, 28/2.8, 50/1.4, A1, T70 (i placed low bids, not expecting to win)
   
3. Samyang 35/1.4 230pounds, new @amazon.co.uk
