jaques Posted August 15, 2017 Share #241 Posted August 15, 2017 Advertisement (gone after registration) There were very subtle mechanical differences between the models in the past, and it happened before that specific lenses could have problems with certain camera models, but this was in the M2/M3 era, as far as I remember. Tiny little things can be of importance, small differences in size can prevent locking. Nothing too serious I’d guess. I wonder if Leica engineers are aware of all these differences … Oh, and the digital Ms differ widely from the old analog Ms. Well, it is not the mount itself that differs (or at least not significantly), but what is behind it. You can’t mount the Dual-range Summicron on any digital M, not even on the M10 (with its protruded mount). Maybe it is something in this regard with the M4 and the 7A. you can mount the DR summicron- but only at the close focus setting though (from memory). I did it years ago on an M9, can't remember the details just now Link to post Share on other sites More sharing options...

For the Dual-range Summicron on the M10 you might have a look: https://www.l-camera-forum.com/topic/269876-m10-can-be-used-with-somni-50mm-dr-full-range/ If the M4 was different in some regards it's astonishing that nobody ever seems to notice or to mention it - before the "7artisans" lens appeared.

There’s just not enough room behind the mount in the M10. Even if you can only nearly use the DR, this is not enough for practical use (and it depends on the individual DR you have). I think Leica engineers could have done it, but it seems that they don’t care (because some people are right that you don’t need the DR anymore, but for me it is one of the most essential Leica lenses of all time).

UliWer Posted August 15, 2017 Share #245 Posted August 15, 2017 Sorry - but did you look into the thread about the Dual-Range Summicron on the M10? Link to post Share on other sites More sharing options...
adan Posted August 15, 2017 Share #246 Posted August 15, 2017 The thing with the 50DR on the M10 is that it is borderline - and some lenses work, but some apparently do not, just due to sample variation. I had one that just barely worked - at infinity, you could sense that it would jam and bind if it been asked to focus any further, but it WOULD reach infinity. There was also a focused position that made mounting more difficult (I can't recall now where on the focusing scale, or whether it was with or without the goggles - eventually swapped mine for a 75 f/2.4 Summarit, which offered identical close-up ability, plus 6-bit coding). 1 Link to post Share on other sites More sharing options...
caugustin Posted August 15, 2017 Share #247 Posted August 15, 2017 Advertisement (gone after registration) Sorry - but did you look into the thread about the Dual-Range Summicron on the M10? If it worked for some, nice. I did a test with my DR on an M10 and it did not fit (not enough room behind the mount). Simple as that. And what I saw was "it mounts in close-focus mode" or "my one does only focus up to 10m" etc. What else should I look for? Link to post Share on other sites More sharing options...
greg_may_ Posted August 15, 2017 Share #248 Posted August 15, 2017 In the few pics I posted a while, the one with the brick wall, did you notice anything? Soft corners and swirl don't offend me too much. Dog does look like he needs a tickle though. Others images have made me happy enough with what the lens can do, time will tell if it works for me.

caugustin Posted August 15, 2017 Share #249 Posted August 15, 2017 If the M4 was different in some regards it's astonishing that nobody ever seems to notice or to mention it - before the "7artisans" lens appeared. Not astonishing at all – as long as the small difference did not affect anybody, they don’t notice (and therefor don’t mention it). Now the 7A stumbled about a detail that wasn’t on anybody’s radar before. Now at least the folks at 7A know about it … Link to post Share on other sites More sharing options...

I have the 2.4/75 Summarit too (by now), and it is a really nice lens – but better suited to portrait than for what the 50DR was made for. I do prefer the image rendition of the 50DR (the Summarit does have its virtues, but it is just different), and it is the more universal lens (at least for me). The 7A could be a nice addition for low-light (were soft edges do not count). I’m thinking about a combination of my 2.8/35 Summaron (distortion free, good for all sorts of subjects), 1.1/50 7A (technically inferior, but of high practical value in some areas) and the 2.4/75 Summarit-M (visible pincushion distortion, but good for close-up and portrait, and with a nice overall image rendition).

Robert E Posted August 23, 2017 Share #251 Posted August 23, 2017 "Unfortunately, and despite all the Chinese expertise, extensive r&d and exhaustive qc that apparently went into creating this thing, so we're told, it seems it does not mount correctly on a Leica M4." While it's sad the lens does not mount on your M4, that still leaves a lot of other Leica models out there that it does fit and work wonderfully on. Many owners of digital Leica models are really enjoying this lens and the bargain price. So let's not discount it just because it has one fault. On my M-P 240 it has been producing wonderful results and you just have to love the quality and results that are so close to it's Leica counterpart that costs thousands more. I'm just as much a Leica lover and aficionado as most on this board but there comes a time when you just have to be prudent with your money. 5 Link to post Share on other sites More sharing options...
honcho Posted August 24, 2017 Share #252 Posted August 24, 2017 .......there comes a time when you just have to be prudent with your money. Whether your purchase is 'prudent' or not will depend very much on the glue that holds it together and your own definition of being prudent. Time will tell. It's good that people seem to be enjoying it, I hope it doesn't turn into another Hyperprime farce. I wonder why those who have bought the 7A might not have previously considered the CV Noktons or ZM c-sonnar and planar. They are all proven, wide aperture lenses with known characteristics, performance, quality of materials and construction and cheaper alternatives to Leica, if cost is the main driver (which I doubt it is). I'm not dismissing the 7A, but sometimes it's prudent to wait and see. 1 Link to post Share on other sites More sharing options...

jaques Posted September 8, 2017 Share #254 Posted September 8, 2017 OK so my lens arrived- out of the box I was happy with the weight, feel, focusing smoothness. Focus was ever so slightly off- it took me half an hour of fiddling with the included screw driver to get it closer- I think I am just off by a very small fraction now- it gets harder to make adjustments in the sub mm range. Took it out for a spin- I'll let others judge the results: Welcome, dear visitor!
