Had a chance to go out today briefly to take some quick snaps with the ZM25 and Hoya +1 closeup filter combination. These were shot using the techart autofocus adapter in automode with the focus are set to the centre. The shots were made from approx 50 feet away with the lens set to infinity/
My SLB-50-5000PM was received from OptoSigma a few days ago, also.
Just so you know, OptoSigma applies the anti reflective multicoatings themselves. That's why the above label says -1500P, the uncoated version, and "M" is added to the label.

Hello Jim, Thank you for the info. Just to confirm, the lens I just recevied with the letter M written on the label means it has been coated ? ( See image on the last post on page 44 of this thread)
P.S. initial f5.6 before and after corner test shots looks pretty good.

Looks good. Thanks for posting this. I hope to get out this weekend and test mine
I recieved the Zeiss ZM 25/28 hood today, it's pretty expensive but very well made, it looks very good on the ZM25. One thing I am noticing is that I'm seeing a bit of mechanical vignetting in the extreme corners, I think it's related to the thickness of the Hoya housing, need to test it a bit more.

Yes, that is correct, your lens is multicoated. I confirmed this with OptoSigma. I was referring to your photo in my post.
I'll get the hood Monday. I got my final setup for the ZM 35 . Thin 49,49-55, thin 55-52, 52mm Retaining ring. I set infinity one Gold shim removed the rest. Using the Hawks ad
Recently I got a cheap used ELPRO4. It has a 55mm retention ring that can catch 50mm diameter PCX.
Here is my setup. Now I can use G21's original front cap.
G Biogon 21mm + 55mm Blank Filter + SLB-50-1500PM(reverse orientation,rubber tape adhered on the edge for centering) + ELPRO4's Retention Ring
I haven't tried this for the ZM35 but this may help you.
Hello. How are you applying the rubber tape, around the circumference of the SLB-50-1500PM? I noticed my SLB-50-1500PM seems to move around in the step-up ring and was wondering if it could be stabalized. Rubber tape seems to be a good solution.

I have ordered a silicone 50mm o-ring, 2mm thickness. Will let the group knows how it pans out.
The 5m seems to work quite well with 35 'lux fle. From a quick snap shot out of my bedroom window yesturday, corners are exceptable wo. If anyone interested will do a head to head comparison with the ZM 35/1.4.

I cut it into 3mm x 10mm pieces and just put them on three different positions of the SLB-50-1500PM's circumference. To fit the blank filter's diameter, I stacked 2 pieces for each position.
Good news, 5m pcx on Zeiss ZM and 'lux fle 35/1.4 with TAP, I don't need to take out any shim. In fact I'll have to put on additional shim if I want infinity hard stop.
Okay the Hoya +1 filter looks to have a slight vignette at F8 shooting the sky. To me it looks a little to deep the ring itself. Comparing it to a UV filter ring I have looks to be slightly longer and if I can figure out how to take the glass out and move over to the UV filter ring i think it will eliminate the vignette. The question I have is it looks like the Hoya ring maybe a pressure retaining ring and not a screw. There is only one slot in the retaining ring which leaves me to believe its a push in pressure ring. What i may do is grab the 4+ closeup and try that first to get it out so if I scratch that one who cares. But if someone has the Hoya can you look at it and tell me what you think. Im going to run out and test it now and so far it looks to be the easy answer and i can still use my hood with no problems at all.
Okay it is a pressure retaining ring. I got it off the +4 but now the lens falls through the other ring. Dang
I cut it into 3mm x 10mm pieces and just put them on three different positions of the SLB-50-1500PM's circumference. To fit the blank filter's diameter, I stacked 2 pieces for each position.
Thank you. I thought I'd try the same with Gaffer's tape. So far seems to be a snug fit. Also looking forward to what teerrash concludes with the silicone 50mm o-ring.
I think you're right Guy, I checked one of my UV Hoya filters vs a Hoya close-up and the later is 3mm. deeper, that explains the vigneting that you're seeing. I guess that they put a thicker rim in close-ups to protect the glass, which is curved and protrudes on the front. Maybe Zeiss should have used a 49 or 52mm. thread on this lens, but rangefinder lenses weren't intended to be used with close-up filters, so Zeiss can't be blamed either.
Starting from scratch, probably it will be better to buy a 52mm close-up filter an use a 46-52mm step up ring The glass of a 52mm. filter must have aprox. the same diameter of these Proxars, which don't vignette on the ZM25. Of course, that excludes the use of the Zeiss original hood so, no free lunch.

The lens curvature on the Hoya is pretty significant, I think it also would make it difficult to use the original ZM lens cap on the original Hoya, mounting the Hoya lens on a 46mm thin filter housing would definately prevent you from using it.
I just ordered a 46mm normal UV and thin UV filter. Im not worried if the lens extends past the mount since i will have the hood on it. The vignette is very slight so even 1mm shorter might just do it.

I'm taking a different approach, since I already have the +4 sacrificial Hoya close up lens, I ground the front of the housing (approx: 1mm) using a belt sander and polished it up with a fine emery.Looks pretty good, I'm slowly going into "Choppy Land"
