New 35mm Summilux Question

[richfx]

Advertisement (gone after registration)

Can someone explain how the lens shade on the new 35mm ASPH, when installed, seems to slide over / around the edge of the lens beyond the aperture dial where filters are screwed in when the aperture dial and edge of the lens barrel appear to be the same diameter as the lens shade? Can't figure out how this works unless the trim piece in front of the aperture dial is removed or somehow becomes recessed when the shade is screwed on. Perhaps photos of the lens on Leica's site and elsewhere are creating optical illusions.

Thanks,

Rich

The lens comes with the hood screwed in place. Unscrew the hood and you see the male thread for it at the front end of the lens. With the lens comes also a protective ring that screws on that tread to protect it in case you do not want to use the hood (which you damn well should). When the protection ring is in place on the lens, its outer surface is flush with the outer surface of the lens mount.

 

The lens is normally illustrated without the hood, but with the ring. Hence the confusion, I think.

To "visualize" what Lars said - the colorized orange areas in the image below are two interchangeable parts that screw onto an EXTERNAL thread around the front of the lens. Having no effect on the internal threading for filters.

 

Leica introduced the screw-on shade of this type with the 16-18-21 TriElmar in 2006, and has also used it for the 18/24 Elmars, 21/24 Summiluxes, and the Summarit lenses.

 

Cosina/Voigtlander pioneered the technique (among recent Leica-mount lenses) with their 50 Nokton and 75 Heliar around 2001. Except that - to keep Lars happy - they did not include a protective ring. One HAD to use the hood or leave the threads exposed.

 

It can cause confusion. I "saved a sale" for a local store after the saleman and customer had spent 20 minutes trying to fit a hood onto a 75 Summarit, not realizing they had to take off the protective ring. They'd given up, and the customer was going out the door, when I twigged to what they were talking about and showed how the ring came off. Customer left (again) having bought the shade.

Aha. Mystery solved. Thank you very much Lars and Andy.

Nice work Andy. Two pictures can say more than c. 150 words, even though they are mine.

This must be a new idea, I don't think any of the other lenses with a screw-onto lens hood have the spare ring.

I didn't know there was a spare ring to replace the hood... is there a part number for it? If it came with the lens, I didn't see it.

[gjames9142]

Funny because I just bought one to go on a version 4 elmarit 28, as per a poster's recommendation, and tried for about ten minutes in the store to get it on. I finally managed it. There were, of course, no diagrams or instructions in the box it came in.

Musta got it from the D-Lux 4/5, where you remove a ring at the base of the lens to install the adapter needed to use lens accessories.

 

Insidious, these Panasonickers.

 

 

Now we can lose front cap, hood, and lens front ring. Good thinking, Leica!

 

 

Thanks for the question and answers. I had no idea this was going on.

 

 

BTW, Andy: great false-color work! Nicely done!

Regarding this fairly new concept of outer threads for a lens hood that can be covered by a ring, if not using the included hood...does anyone know if the Summilux 21mm f1.4 lens came with this ring to cover the outer threads for the screw on hood? I don't think so, but am not sure? In anndition, I believe the 21mm f1.4 Lux takes a series VIII filter. IS the filter for this lens simply drop in the front of the lens and the hood sandwithces in the filter or does the series VIII filter actually screw into the lens dn then the hood screws on...much like the new 35mm f1.4 asph? Thanks!

Well what do you know, I found one in there!!! I have had the lens since July and never knew that protective ring was in the case under the alternate snap-in lens cap.

I have had the Elmar-M 24 for a while which has a similar but not interchangeable hood. Mine, a very early one, never came with the ring, I don't know about the Summarits. maybe they do have it since the hoods are not supplied as standard?

[adan]

Thought I'd posted this but must have forgotten to hit the button:

 

Summarits come with the protective ring in place (which is why the folks in my fable were having a hard time finding the threads for the hood). It looks just like part of the barrel.

[hoppyman]

That makes sense. Personally I think that Leica Camera should have included a ring with the Elmar 24 as well. I shall drop a line to Customer Service and see if I was just unlucky.

There was no such ring in my SX24 box and it came with the hood screwed on the lens...

I have a UVa filter for that lens and it works as you describe it.

The 21 Lux does not have a ring to cover the outer thread. The front element protrudes beyond the end of the lens barrel. Therefore only a brave or stupid person would use the lens without the hood, though I see no reason not have the hood always fitted.

 

The Serie VIII filter drops inside the hood and is secured between the inside of the hood and the end of the lens barrel when the hood is screwed down.

 

The 35mm Lux takes E46 filters which screw onto the end of the lens barrel, and the hood screws down over the lens barrel covering the filter.

.............. The 35mm Lux takes E46 filters which screw onto the end of the lens barrel, and the hood screws down over the lens barrel covering the filter. Mark

 

Mark yes that is so, with the qualifying comment that only the Leica E46 UV or UV/IR fits inside the hood. Other brands do not. This has been discussed in other threads.

So people that want to use other filters need to remove the hood and then use the internal filter thread for filters and/or third party hoods if wanted.

[D&A]

Thanks for all the replies regarding the outer threads of the 21mm Lux compared to the new 35mm Lux asph. I too have heard that only a Leica UV or UVIR (as Geoff and others pointed out) will fit under the new 35mm Lux asph's hood. Sooner or later hopfully someone might come across a B+W or other good 3rd party filter with a thin enough retaining ring, that will also work with this lens and original hood.

Hallo,

Look here: Interesting Leica gear

[richfx]

That is unfortunate. I use B+W 007 filters as protection on all my lenses with the M9. Wonder whether their slim mount model would work with the new Summilux and hood, although they don't currently offer it in 46mm. To my knowledge, Leica doesn't offer a strictly protective / clear filter. They or someone else should to fill this need.

Where exactly is the hang up mechanically speaking with not being able to use non- Leica filters on the new 35mm Summilux?

Rich

[lars_bergquist]

The outer diameter is a little bit too large. The hood can't slip over them.

 

I must say that I am not an admirer of this hood attachment system. If I want to use a polarizer on my v.2 35mm Summilux ASPH I have to interminably unscrew the hood and then use the lens with the thread bare, unless I choose to interminably screw in the protection ring (which I must remember always to bring along) until I remove the filter, interminably unscrew the ring and interminably replace the hood.

 

Leica should have used a quick-action bayonet for the hoods. This system works admirably on all the Zeiss ZM lenses and also on several new C/V lenses. Come to think of it, that is maybe the reason why Leica can't use it ...

 

I should add that I am using the lens without a UVa filter. This cuts down on reflections. This served me well the other night when I made several exposures lighted only by candles (see the "how do you change/view your shutterspeeds?" thread).
