Info on Leitz 90mm f2.8 R lens

[eduardo_pacheco]

This is a follow-up on my earlier WTB post for a lens hood and series

7 filter retaining ring for a Leitz 90mm f2.8 R lens (first version,

serial # 217xxxx). This lens has a so-called built-in sliding hood,

which I believe is held in place by the filter ring which screws onto

the barrel's male thread (51mm according to my measurement with

Vernier calipers). Or does the filter ring require the hood to secure

it in place (as in the 28mm f2.8 R first version)? I'm actually not

too bothered about the hood, the most important thing would be to

have a filter in place to protect the front element. I would be

grateful for any information on this.

As furnished from the factory, the hood is held in place with a ring that has series VII on the outside end. There is then a series VII or 54mm filter retaining ring which holds series VII filters in place.

If you are missing the inside ring that holds the hood in place, the only option is to have one made or get one from Leica,not a likely option.

Eduardo, ver 1 Elmarit-R 90 uses series VII filter with retainining ring

#14161R.<p>

The series VII filter + retaining ring 14161R clear the lens hood; in other words, they are independent on the two section lens hood.<p>

You need also lens cap #14133

You can use Series VII filter with retaining ring 14161 without

the hood.

If you don't need the hood, you don't need cap 14133, which fits the

lens hood. <p>

I don't know what cap fits the retaining ring 14161, which has a outer diameter of 54.9mm; the inner side of the 14161 retainer rim is

tapered and has no thread for filter or cap.

I think you are missing the problem. The hood is held on the lens by a ring that is NOT ment to be removed and will NOT hold a filter. It extends with 54mm or series VII female threads. Evidently this ring is missing along with the hood. Without this ring the hood would pull off when extended.

 

the 14161 series seven filter ring screws into the missing part and will hold a series VII filter in its recess. No threads are provided at the outer end of the 14161. Generic adapter rings were made years ago that had female threads at the outer end so more stacking was possible.

 

If you need further clarification, please advise. Third try is the charm.

Thanks a lot for your advice. It looks like I just may have to live with the limitations of this lens. That's probably why it was so cheap, only 100 pounds. Leica UK said they might be able to obtain a retaining ring from Germany, I'm not sure if they meant the hood ring or the filter ring. The lens is older than I thought, serial #2171482 is supposed to be from about 1966. It's amazing it's still in such good condition, apart from the missing hood.

Eduardo,

 

Buy a 54mm to 55mm Step=up ring. This iwll allow you to use 55mm filters (choice of BW or Heliopan filters) Then you can use metal telephoto lenshood from BW or Heliopan also. It may not be original, but hey it will do the job.
