new 35 cron clicks past f/2

I guess it's the kind of problem where someone spends good money for 'legendary quality' and receives something they feel is less than legendary quality.

 

That said, I recently purchased a used 35 cron asph and it had this same issue of moving past the end f stops. I was originally concerned. I also just picked up my brand new 50lux yesterday and it does the same thing (woohoo got it a month early!). Its just weird because I also have 2 cv and 1 zeiss lens and they stop at the ends. Thankfully it is a non-issue.

 

Personally I plan to just shoot and consider having them adjusted if i need to send them in for a differen reason.

I'm sure that if you send such a lens to Leica you will get it returned unaltered with a terse note: "Konstruktionsbedingt". I.e designed this way

I genuinely don't understand the tone of some of these responses.

 

I also noticed this particular 'feature' in about 50% of my lenses, and it hasn't ever worried me. But I totally understand that someone 'upgrading' from another system might wonder whether their brand-new lens has some fault which needs fixing.

 

We have to get a reality check and realize that a single one of these lenses can cost way more than the vast majority of people will spend on their entire photographic equipment. And when a new Leica user buys into the M-system they don't expect the front of a lens to wobble or aperture rings to click past the marked settings, and so on.

 

I therefore fail to see why they get this dismissive attitude - a polite explanation is all that's required.

It is just a fact. I got such a response when I sent a Vario-Elmar in because the zoom ring does not run smooth - in fact el-cheapo notchy.

Thank you so much for this comment. It is exactly right on target. I have never owned this lens before. No lens I have ever owned does this. I bought a new lens, and was merely wondering if Leica's INTENT was to make the lens this way. I want to thank this poster for relaying my thoughts.

As is mentioned it has to do with the design, it isn't as a result of some kind of poor assembly but a necessary "fault" to get the aperture ring to function and feel as it should. Ultimately the mm or so that it rotates past f/2 probably can't and/or shouldn't be altered as it would change the feel and free movement of the ring itself.

 

If this is the only thing inherently "wrong" the Summicron 35 ASPH then be happy that you own one, because 1/2 a mm is a lot better than any alternative.

It's about tolerances. Metal (which Leica lens barrels and aperture blades are made from) expand and contract depending on the climate. I guess many people coming to Leica these days have come from cameras/lenses that didn't even have aperture rings!
