hmzimelka Posted July 30, 2022 Share #1 Posted July 30, 2022 Advertisement (gone after registration) Hi all. Something recently struck me as a little odd when registering my new Summicron-M 50mm 11826, is that I thought it was the Version 5... but Leica seems to classify it as version 4 (IV) Anybody know why the lens known as version 5 is classified as version 4 by Leica?

a.noctilux Posted July 30, 2022 Share #2 Posted July 30, 2022 I would not worry for the name of version. depending on criterias of numbering, optical cell or whatever many Leitz or Leica lenses are designed by order number which is more precise than versions ( as here ...Leica Order No. - 11819-black, 11826-black, 11825-silver, 11816-silver, 11624-titan, 11619-silver (S), 11615-silver-50yr from Wiki version IV (same optical cell) began life in 1978 a while back with so many "order numbers" since then 1 Quote Link to post Share on other sites More sharing options...

TomB_tx Posted July 30, 2022 Share #4 Posted July 30, 2022 There were 4 optical versions of the 50 Summicron, so in that sense the latest is version 4. However, the mechanical mount was changed during its production to the current "built-in hood" style, so many call this version 5, even though the optics didn't change. 2 Quote Link to post Share on other sites More sharing options...

evikne Posted July 30, 2022 Share #8 Posted July 30, 2022 Same with the last version of the 50mm Summilux pre-ASPH. Some call it v3 and some v2, because the optical recipe is unchanged. Quote Link to post Share on other sites More sharing options...

hmzimelka Posted July 30, 2022 Author Share #10 Posted July 30, 2022 Yeah, ok. This is making some sense now with regard to optical design being the same, hence V4 naming. This is what searching for 11826 and 11819 on club.leica-camera.com returns... Welcome, dear visitor!

kivis Posted August 11, 2022 Share #11 Posted August 11, 2022 I think the tolerance and ergonomics a bit better on the V5, but you can't go wrong with either one. 1 Quote Link to post Share on other sites More sharing options...
RexGig0 Posted August 11, 2022 Share #12 Posted August 11, 2022 (edited) For a bit of trivia, here is a link to Erwin Puts’ page on the 50 Jahre Special Edition, with Version IV optics, that bears some external resemblance to the earlier Rigid. To be clear, the 50 Jahre part refers to the fiftieth year of the 50mm Summicron lens. I really like the aesthetics and ergonomics of this one. https://photo.imx.nl/leica/lenses/lenses/page92.html Edited August 11, 2022 by RexGig0 1 Quote Link to post Share on other sites More sharing options...

Also it has a focus tab and is significantly more compact. It has no built-in hood though and was not natively 6-bit coded. Matter of taste but i agree that one can go wrong with neither. Here Canada made v4 and v5. Welcome, dear visitor!

When I was assessing the v4 / v5 models I preferred the smaller form of the v4 and, with a 12585 hood fitted, found there to be less vf blockage than the v5 with hood extended. The v5 is also 25% heavier than the v4. But yes; all said and done it really does come down simply to individual preferences and either one will be a stellar performer.

Matlock Posted August 12, 2022 Share #15 Posted August 12, 2022 I have the v5 in both M and LTM and I find them both great performing lenses, 1 Quote Link to post Share on other sites More sharing options...

Just curious as last time i checked i got 235g for v5 and 215g for v4 + 12585 hood. 20g difference would make v5 10% heavier more or less. No big deal but my favorite version w/o hood is the bare v4 (200g?), especially the German variant whose coatings look identical to v5's. 1 Quote Link to post Share on other sites More sharing options...

No, lct, the 12585 wasn't included in my calculation so I agree that my percentage was unfair. My Fault! Philip. 1 Quote Link to post Share on other sites More sharing options...
