jplomley Posted January 1, 2020 Share #21 Â Posted January 1, 2020 Advertisement (gone after registration) Very odd given the zooms are silky smooth. My 16-35 is like butter, my 75 is just ok, but nowhere near as nice as the 16-35 mm 1 Link to post Share on other sites More sharing options...
Advertisement Posted January 1, 2020 Posted January 1, 2020 Hi jplomley, Take a look here SL APO Summicrons stiff focus. I'm sure you'll find what you were looking for!
Daniel81 Posted January 2, 2020 Share #22 Â Posted January 2, 2020 It's my biggest disappointment with my SL 75 . . . one would think for a lens at that price, manual focus would be buttery smooth. Â Its not. Â It is stiff and not only stiff but moving in and out of focus is a jerky and non-reproducible experience. Â Massively expensive lens - the MF is a technical failure as far as I am concerned. Â Otherwise, of course, stellar lens. Â How could they get this so wrong? 3 Link to post Share on other sites More sharing options...
Renata Posted March 8, 2020 Share #23  Posted March 8, 2020 Today I tried manual focus for the first time since I bought the 35mm APO-Summicron-SL one year ago, and I couldn't do it. The focusing ring doesn't turn at all. Stuck! Is it supposed to be like this? Link to post Share on other sites More sharing options...
Exodies Posted March 8, 2020 Share #24 Â Posted March 8, 2020 Is the camera the SL1? Is it the latest firmware? Link to post Share on other sites More sharing options...
LocalHero1953 Posted March 8, 2020 Share #25 Â Posted March 8, 2020 (edited) See my post #3. The SL 90 was returned by Wetzlar to Leica London, who decided, without checking with me, that it still wasn't fixed, and sent it back again. I received it back home a couple of weeks ago, and it is now fine. Leica must know this is an issue. If it's a problem with your lens, send it back under warranty.

Jon Warwick Posted March 8, 2020 Share #28  Posted March 8, 2020 (edited) I was trying a demo SL 90mm Summicron in a dealer, who himself commented how stiff the manual focusing was and the lens might need to be sent in for fixing. Hopefully it was just a teething issue, but now recognised and fixed in later production cycles, rather like the flare was on the initial M 50 APOs? Disappointing nonetheless, I’m always amazed these things don’t get resolved in beta testing.  Edited March 8, 2020 by Jon Warwick 2 Link to post Share on other sites More sharing options...

Superb optics, no complaints. Jeff Link to post Share on other sites More sharing options...
MarkinVan Posted May 19, 2020 Share #31 Â Posted May 19, 2020 My SL35 has been a total delight since the day I opened the box and is the most consistent lens on my camera. 1 Link to post Share on other sites More sharing options...
RMF Posted May 19, 2020 Share #32  Posted May 19, 2020 Nothing but great things to say about my SL 50 Cron; it’s very smooth out of the box in manual focus. Link to post Share on other sites More sharing options...
Photoworks Posted May 19, 2020 Share #33  Posted May 19, 2020 I am having issues with the zoom ring of the 24-90 . it gets stock sometimes and doesn't go in any direction.. focus still ok.. so disappointing. got the lens used and didn't the day I got it. I don't ever want to send in because it is going to take so long to get the lens back Link to post Share on other sites More sharing options...

I am looking to get a 50 SL - and want to ensure that I get an unproblematic sample in this regard. Link to post Share on other sites More sharing options...
nicci78 Posted June 17, 2020 Share #36  Posted June 17, 2020 Crazy ! Thanks for sharing the issue. Summilux-TL 35 and APO-Macro-Elmarit-TL 60 have buttery smooth focusing ring. They are both made in Wetzlar too. What's the problem ? Made in Germany TL lenses have aluminium focusing ring. But APO-Summicron-SL have rubber ring. Is that the problem ? Link to post Share on other sites More sharing options...
georg Posted June 18, 2020 Share #37  Posted June 18, 2020 I had an early Apo Summicron SL 90 for testing, it was stiff with a strong stick&slip effect and slight squeaking. I am pretty sure it's an issue with the rubber sealing, newer lenses I tested were just fine. The ring underneath the rubber is aluminium as well, but the sealings are a big difference to TL lenses.

lx1713 Posted June 20, 2020 Share #38  Posted June 20, 2020 My 35, 50 & 90 are very stiff when I bought them a few months back. They have gotten much smoother with usage. 1 Link to post Share on other sites More sharing options...
AZach Posted June 20, 2020 Share #39 Â Posted June 20, 2020 SL APO-SC 90 (purchased 03/18) always smooth, no sound. Link to post Share on other sites More sharing options...
Boojay Posted June 20, 2020 Share #40  Posted June 20, 2020 (edited) SL 50 APO - date of manufacture 29/11/2019 - smooth and quiet SL 90  APO - date of manufacture 15/06/2018 - absolutely dreadful, stiff and noisy - impossible for MF - will be heading to Wetzler when things calm down.      Edited June 20, 2020 by Boojay Link to post Share on other sites More sharing options...
