kuchars22 Posted December 10, 2022 Share #1 Posted December 10, 2022 Advertisement (gone after registration) I’ve bought said lens and the focus ring goes beyond 0.7m, ie it doesn’t fall over the centre scale of the aperture range. Rather the “0.7” falls in the right side of the scale between the 8 and 16 marker. Is this normal? Welcome, dear visitor!

Advertisement Posted December 10, 2022 Posted December 10, 2022 Hi kuchars22, Take a look here 50mm summicron v5 - is this normal?. I'm sure you'll find what you were looking for!
Jean-Michel Posted December 10, 2022 Share #2 Posted December 10, 2022 Hi, This is perfectly normal. The rangefinder works all the way to the hard stop. If you have an EVF or live view on your camera you can verify that for yourself. 1 Quote Link to post Share on other sites More sharing options...
kuchars22 Posted December 10, 2022 Author Share #3 Posted December 10, 2022 So it would still be 0.7m MFD? Quote Link to post Share on other sites More sharing options...

lct Posted December 11, 2022 Share #5 Posted December 11, 2022 Don't worry, most M lenses (Leica, CV, Minolta), including Summicron 50/2 v4 and v5, are more or less like that. Only exceptions i know of are Zeiss ZM lenses and Konica M-Hexanon, as far as my copies are concerned at least. The M-Hexanon 50/2, for example, is very close to the Summicron 50/2 v5 but its focus ring has a stop at 0.7m. Great lens BTW. 1 Quote Link to post Share on other sites More sharing options...
Huss Posted December 11, 2022 Share #6 Posted December 11, 2022 Normal. Mine does that too. Quote Link to post Share on other sites More sharing options...

It is 0.7m MFD where the rangefinder can focus to. Closer than that it disconnects, even though the lens focuses a little closer. Quote Link to post Share on other sites More sharing options...

You can accurately measure distances using the engraving on a Leitz/Leica "M" lens. The engravings are correct distances. The distance measured is from the film/sensor image plane to the point focused on. Many "M" cameras focus a little closer than the stated close focus distance.. Why not try an experiment: Put a meter/yard stick under your camera/lens & set the lens to 1 meter/3 feet. Then put something on the stick/on the end of the stick at 1 meter/36 inches. Then slide the stick so that the 2 rangefinder rectangles match with the camera/lens on top of the stick. This will also show you where the film/sensor plane is. Then slide the object down to 0.7 meters/28 inches & refocus to see if it measures correctly. Then turn the LENS to the closest distance that it will focus to & slide the focusing object to the point where the 2 rangefinder rectangles match & read the distance. And, please let us know what it reads. Best Regards, Michael Edited December 11, 2022 by Michael Geschlecht 3 Quote Link to post Share on other sites More sharing options...

Yes I have the evf2 and not had problems focusing at near hard stop distances. The reason for my question is that i just bought it from ebay, the focus ring is a bit rough at the wider end, as if it’s going over a few bumps. Its more noticeable when the lens is upside down so the aperture distance gauge is pointing downwards. So as i was videoing the fault for the seller, I then noticed the 0.7m wasn’t lining up.

It is actually the nicest feeling lens that I have, and from what I have seen, this is how the Summicron V is. It’s one reason why we buy Leica lenses! Even my old Summicrons from decades ago are smooth. I don’t know what is up w yours but I wouldn’t want it. Is there any sign of impact damage? Perhaps the previous user used the focus ring to grip the lens to release and attach it to the camera. Quote Link to post Share on other sites More sharing options...

Perhaps the previous user used the focus ring to grip the lens to release and attach it to the camera. possible. the red dot is missing but i’ve seen that before, and some anodising off the aperture ring. It’s hardly noticeable when the lens is in the normal “upright” position, but more noticeable when pointing down or upside down, not that i would photograph inverted, but proves that the problem exists when weight of the helicoids press up against each other in certain positions. I got it cheap (£700) and is still very useable, so will get it serviced anyhow. Quote Link to post Share on other sites More sharing options...
Molokaio Posted January 11, 2023 Share #16 Posted January 11, 2023 Also mine goes beyong 0.7m Mine is from 2002, super smooth. All the lenses I have are super smooth, also older ones. Maybe yours just needs CLA. 1 Quote Link to post Share on other sites More sharing options...
TomB_tx Posted January 11, 2023 Share #17 Posted January 11, 2023 When I bought a new v5 Summicron the focus had quite a rough feel over part of the range, unlike the v3 I had used for decades. I remembered a Leica rep back in the 1960s say that the thread clearance on Leica lenses was much tighter than other makes (which used thicker grease so you wouldn't feel the slop), and that many Leica lenses needed to be exercised a lot to "wear in" the helicoids. So I spent a few evenings constantly moving the focus back and forth through the range. It became perfectly smooth and light. OTOH, I also have a used v1 Summilux that is quite smooth in normal (horizontal) hold, but had a definite "catch" with the camera held in vertical format. Otherwise the lens is fine, so I decided to live with it rather than invest in a CLA. (I don't use the Summilux much.) Since yours is a used lens I'd suspect something similar - but you can try exercise and see if it helps. 1 Quote Link to post Share on other sites More sharing options...
kuchars22 Posted January 11, 2023 Author Share #18 Posted January 11, 2023 Going to keep it as it is - it’s not bothering me much thinking about it now - perhaps i was aiming for perfection being my first leica lens, but it doesn’t detract from the overall use. You barely feel the problem Quote Link to post Share on other sites More sharing options...
