Leica 35mm Elmar f/3.5

I picked up a Leica Elmar 35mm f/3.5 lens on the auction site the other week, it arrived yesterday. It was CLA'd by Youxin back in Nov 2017. The glass looks good, but the focus and the aperture are both really stiff. They are smooth, but much harder to operate than my 50mm Elmar of the same era (or any other lens, for that matter).

It's enough that I would consider returning the lens, or sending it back out to Youxin or Dag to look at.

I'm just curious...he showed me the receipt from Youxin, so I believe that it was looked at already, what could cause this?

Thanks,
Brad

Most likely lubricant. Probably it was CLA'd and left alone, without use. Probably exercise a bit (a day or two?) to see if it improve?

My Elmar 35mm is quite easy to focus but aperture is a bit stiff. Probably would need a CLA on the future.

All the Elmars 35mm f/3.5 are a bit stiff; it is normal; they're small lenses, but have a double focusing thread: one for pulling the optical unit in and out and the other for moving the rangefinder curve. All Leica lenses - except 50mm lenses - have double focusing threads. This is because the rangefinder is standardized for 50mm lenses. The movement of the rangefinder curves of all other lenses must somehow be compensated to mimic the 50mm lenses.

Thanks Erik. That wouldn't apply to the aperture adjustment, correct? Because that is also stiff, and again, while smooth, it is somewhat difficult to move.

Yes, but the lever of the aperture is also very small. However, I've seen 35mm Elmars with very smooth aperture levers. If the glass is clear, I would leave the lever as it is, but if there is haze - normal for such a small lens - the lens needs servicing.

Gotcha. And yes, that lever is small.

I think I'll send it to Youxin. I think that I can trust him to let me know if I'm correct that things are too stiff or if it's to be expected.

I have had one of these for two years. It was stiff to focus and set the aperture and still is. If I use it regularly, both loosen up slightly. Since the images it produces are stellar, I'm going to leave mine alone. Have you shot with yours yet?

It's on my camera now, I've taken some shots with it...haven't finished or developed a roll yet.

It's not really fun to use, as stiff as it is right now, so I'm not sure where I stand on it. I see what you are saying. But I'm leaning towards seeing if Youxin can do anything. And if he can't....it's probably going to find a new home.

The Elmar 35mm is an excellent lens.

Erik,

I think you could make any lens produce excellent results.

I wish that was true, but the Elmar 35mm is really a very good lens, even by todays standards.

By the way, any idea why is common to find haze on this lens? Mine had it as well. Most of the ones I've seen have it, even on otherwise perfect examples. Lubricant?

I had the 3.5cm elmar when I had my IIIa and M2 (which I believe you bought the M2 from me on ebay Punkzter) and the hood that I used for it, while not being the proper hood I believe it allowed me to easily adjust the stiff aperture as it had the cutout for it and you move the ring on the front of the hood to easily adjust it.

If, less than two years after the last service, you decide to let someone else try his hand, I can wholeheartedly endorse DAG. My stiff 35mm Elmar f/3.5 returned mechanically perfect and silky smooth, and remains so a year later. It’s a pleasure to use and the results are something special. Mine is coated, from the last batch.

The lens is very small, the lubricated mechanical parts are very close to the optical elements, so the evaporating solvents deposit on the lenses easily.

That aperture control hood seems really awesome. I'm guessing it's the VALOO? Did you have any issues using that with the 35mm lens? It's designed for the 50mm right?

And yes, I did buy your M2..small world.

If the lens has been serviced recently wouldn’t the helical lubricant be some synthetic that out gassed less or not at all? Do modern lubricants still have that problem?

To be clear, I think that Erik was answering a question that would refer to lenses that had not yet been serviced. My lens, which was recently serviced, does not have any haze issues.

The VALOO works fine on the 3.5cm Elmar. There is some minor mechanical vignetting just the very very edge of the corners. The hood is a good match.

Yes, this is what I experienced with that hood on the 3.5 Elmar, but in no ways was it really bad.

How's that M2 holding up? Good I hope.

I always understood that VALOO was primarily for darkroom and close focussing attachment use with 50mm Elmar. Although handy for adjusting the aperture it is comparatively heavy and (in my opinion) spoils the balance.

I agree with Michael here. The FOOKH is the most beautiful shade for the Elmar 35, but not only for the Elmar 35, also for the Elmar 50 and the Summar. It is wide enough for even the thickest fingers to change the f-stop.

Erik.

I never got on with the 3.5 35mm Elmar, maybe it was a poor example or more likely I am a poor photographer. However...when I sold it I kept the FOOKH.

This in Leicashop is my favourite 35mm though mine is not in the same condition....nor did it cost that much!!!

I didn't realise it has its own specific code number.

That price was a shock, I'll think twice before taking mine out of the house...

Like the old adage "Ships are safer in the harbour....but that's not what they were built for."

Yes Summarons seem to have taken a jump lately. Elmar 35mm on Ebay seem to range from $200- $1000 USD.....(the latter price being quite a stretch IMO)...i may have paid $150 for mine.

Erik,
Don't you mean the FLQOO, which is the hood that you illustrate. The FOOKH is the later hood for 35mm Summaron and Elmar.
The FLQOO you have mentioned in other posts as your favourite is what you illustrate and was introduced in black in 1936 for the Elmar 3.5cm.

Yes, you are right, the large one is the FLQOO and the short one is the FOOKH.
I'm getting old I guess.
For the Elmar 35mm f/3.5 the FLQOO is the best.

My 35mm Elmar focuses very easily and smoothly, and the aperture is very easy to change. It was serviced by DAG earlier this year. One that is stiff in focusing likely needs serviced, that is not normal.

On my Elmar 3,5cm f3.5 lens which is scaled in "metres" and is a war-time lens, Leitz seem to have "gone over the top" with engraving focusing marks
on the distance scale.
Most examples of this lens have 13 engraved marks.
They are 1, 1.25, 1.5, 1.75, 2, 2.5, 3, 4, 5, 7, 10, 20, infinity.

My lens made in 1941 (Serial No.570569) is engraved with 18 marks.
They are 1, 1.1, 1.25, 1.4, 1.5, 1.6, 1.75, 2, 2.2, 2.5, 3, 3.5, 4, 5, 7, 10, 20, infinity.
I wonder why they have engraved the 5 extra marks ?.
I have just noticed my 5cm f3.5 Elmar (Serial No. 571829) also (1941) is engraved the same.
Why are the extra distances needed in war-time. Any ideas anyone?.
