Advertisement Posted November 21, 2016 Posted November 21, 2016 Hi MediaFotografie, Take a look here SL 50/1,4 data sheet online. I'm sure you'll find what you were looking for!
jrp Posted November 21, 2016 Share #2 Posted November 21, 2016 Well it may be new on the website, but it was written in July. It looks like the new lens is as good as it gets centrally from the widest aperture, even close up, and stopping down improves that edges a bit, although it is hard to tell how much of that is field of focus curvature.

dancook Posted November 21, 2016 Share #4 Posted November 21, 2016 The SL is digitally corrected, do these diagrams ignore this? Link to post Share on other sites More sharing options...
scott kirkpatrick Posted November 21, 2016 Share #5 Posted November 21, 2016 The SL is digitally corrected, do these diagrams ignore this? Since they no longer give the distortion and vignetting curves in the technical data, I presume that the document assumes they are corrected in the camera or in post-processing, following the instructions "baked into" the DNG file. or in the final steps of creating an in-camera jpeg. I'm more curious about the absence of the several pages of depth of field charts that used to be in these documents. Especially since Peter Karbe has said that sharpness falloff in the new Summicron-SLs is tuned to be the same as in the Summilux. So it would be interesting to see how they now specify depth of field. Except they don't. scott Link to post Share on other sites More sharing options...

dgktkr Posted November 22, 2016 Share #7 Posted November 22, 2016 Advertisement (gone after registration) The Apo-Summicron MTF Diagrams look better. http://en.leica-camera.com/Service-Support/Support/Downloads?category=93719&subcategory=&type=&language=all OK. But shouldn't there also be a comparison with the Summilux M 50mm f/1.4 Aspheric? As far as the MTF curves indicate, it appears that the Summilux-SL 50mm f/1.4 Aspheric is a bit better than its M brother and it has autofocus. If one would rather have better definition at the expense of being one stop slower, then the 50mm f/2.0 Summicron-M Aspheric might be a better choice. Unfortunately, for the time being, one doesn't have the option of a 50mm f/2.0 Summicron-SL (with autofocus). dgktkr Link to post Share on other sites More sharing options...
John Black Posted November 22, 2016 Share #8 Posted November 22, 2016 Wow, you guys are being really kind - did you notice the weight? 1.065 KG...!... I knew the lens would be heavy, but hoped it would keep under .8 KG. I knew that was unrealistic, but still hoped I look forward to seeing how the Leica 50 Lux SL compares against the recent Sony 50/1.4 ZA for the A7 cameras.

John McMaster Posted November 22, 2016 Share #9 Posted November 22, 2016 Indeed, it is a similar size and weight to many of the S lenses! john Link to post Share on other sites More sharing options...

orc999 Posted November 23, 2016 Share #11 Posted November 23, 2016 I was really about to just preorder it, the more then 1kg is killing it though, need to reconsider. MTF looks great. Of course in it's defend the otus is even heavier and has no AF mechanism to accomodate. Link to post Share on other sites More sharing options...
jrp Posted November 23, 2016 Share #12 Posted November 23, 2016 Not clear where this lens would be worth carrying. Yes, it is two stops faster, but the zoom has OIS. So it is really a special effects (narrow field of focus) lens. Taking portraits at f1.4 is not usually very useful, as only (part of) an eye will be in focus, so the field of application is narrower still.

steveBK Posted November 23, 2016 Share #14 Posted November 23, 2016 How are we a full year into the SL system and they haven't figured out how to release a lens weighing less than 1kg? Meanwhile we have mirrorless medium format coming out with leaf shutter integrated lenses @ 500g coming out. Link to post Share on other sites More sharing options...
John McMaster Posted November 23, 2016 Share #15 Posted November 23, 2016 The Hasselblad lenses are much slower.... john Link to post Share on other sites More sharing options...
LD_50 Posted November 23, 2016 Share #16 Posted November 23, 2016 The SL system obviously is not designed to be light weight. It's not that it hasn't been figured out. You can shoot M lenses on the SL or the M system for lighter weight and smaller size than what is offered by just about any FF system. It was figured out decades ago.

jip Posted November 23, 2016 Share #17 Posted November 23, 2016 Indeed, it is a similar size and weight to many of the S lenses! john The 70mm 2.5 Summarit-S WITH central shutter weighs 835 grams without the hood. Link to post Share on other sites More sharing options...

MediaFotografie Posted December 5, 2016 Author Share #19 Posted December 5, 2016 ...here's a quick comparison of Summulix-SL, Varia-Elamrit-SL @50mm, Summilux-M, Apo-Summicron-M 50mm and Otus 55mm. My thoughts: Summilux-SL looks very fine - except of 40 LP sagittal; what did Peter Karbe do there? the Vario-Elmarit-SL is impressive I think we will see real world examples in the next days.
