SrMi Posted February 8, 2023 Share #21 Posted February 8, 2023 Advertisement (gone after registration) 4 hours ago, LocalHero1953 said: The 24-70 zoom is reportedly not a straight rebrand of the Sigma equivalent, but with one element made from a different glass, and possibly different coatings. Leica might do the same with these. A number of people here seem to have chosen the lighter 24-70 over the 24-90. I was puzzled at first, reading the rumours, but I guess Leica can see a benefit in getting punters hooked on the Leica habit: (1) making a decent margin on whatever they pay Sigma/Panasonic and (2) a stepping stone to the more expensive in-house apo versions. It keeps the Leica lens release programme going while they work out whether they are going to issue the wide angle primes or not. I would also be interested in a longer prime than 90 - I use the 90-280 a lot. Whether a fast 135 or 180 apo lighter or smaller than the 90-280 is feasible is another matter. The Apo-Summicron-R 180 was 2.5kg! But a 135mm Apo-Summicron under a kilogram would be interesting. I would also like to see a 135 or 180 as long as they are not too heavy. The R 180/3.4 is only 750g. Batis 135/2.8 is less than 700g. 2 Link to post Share on other sites More sharing options...
Advertisement Posted February 8, 2023 Posted February 8, 2023 Hi SrMi, Take a look here Leica 35/2 and 50/2 SL ASPH lenses?. I'm sure you'll find what you were looking for!

Batis 135/2.8 is less than 700g. Since I have the 90-280 already and can live with its weight (while still grumbling), a new lens would have to be significantly faster to make me want it as well or instead: 3.4 wouldn't be enough, and probably not 2.8.

Those Panasonic lenses are built to a target price. Leica can make changes to the bill of materials that wouldn't be justifiable in a sub $1,000 lens. 1 Link to post Share on other sites More sharing options...
Planetwide Posted February 8, 2023 Share #24 Posted February 8, 2023 (edited) I own the Panasonic 85mm F1.8. It's a nice lens for the price. Good bokeh, and quite sharp, but it has significant CA on the OOF highlights. It has been optimized for focus breathing, and consequently suffers, in absolute terms, for still photography. The size would accommodate a redesign of the elements. I hope that Leica can replicate the look of M Asph summicrons. My wish would be for the 35mm/F2 to replicate the V4 summicron. Rebadging lenses is ok, but I agree, where is the 21mm? Leica seriously needs to throw the SL line some love...

Planetwide Posted February 8, 2023 Share #25 Posted February 8, 2023 Something just occurred to me. If Leica can create a very good line of light weight, and characterful F2 lenses, then this would set the stage for a L mount Q/M style body. 1 Link to post Share on other sites More sharing options...
bandrews Posted February 8, 2023 Share #26 Posted February 8, 2023 Just got the email through from Leica. Looking forward to seeing some reviews. The original lenses were too big/expensive for my tastes. 3 1 Link to post Share on other sites More sharing options...
oldwino Posted February 8, 2023 Share #27 Posted February 8, 2023 Advertisement (gone after registration) Repackaged Lumix primes, which are very good lenses. Not convinced the extra cost for the better build quality will be worth the price difference. I’m sure there’s better QC too. 2 1 Link to post Share on other sites More sharing options...
nicci78 Posted February 8, 2023 Share #28 Posted February 8, 2023 is this the new purpose of L-mount ? Rebadge Lumix S & Sigma DG DN as Leica SL lenses ? Will be get a rebadge S5 mark II as SL3-S soon ? Link to post Share on other sites More sharing options...
LocalHero1953 Posted February 8, 2023 Share #29 Posted February 8, 2023 (edited) Well, there they are: Summicron-SL 50 Asph and 35 Asph, at half the price. Now on Leica's website. The question mark can be removed from the thread title. Edited February 8, 2023 by LocalHero1953 Link to post Share on other sites More sharing options...

BernardC Posted February 8, 2023 Share #32 Posted February 8, 2023 Comparing the specs for the 35, Leica's version weighs 400g, Panasonic's is 295g. The 10Lp/mm MTF is significantly higher for Leica's version: it just crosses the 80% at the very edge of the field. Panasonic's MTF goes down to 70 for the sagittal line, and the spread between sagittal and tangential is much bigger. Unfortunately, the two MTFs just have 10Lp/mm in common (Panasonic shows 10 and 30, Leica shows 5, 10, 20, 40). I'm sure that people will discuss whether or not these differences are valuable to them, but it seems that this is not just a "re-badge." 5 Link to post Share on other sites More sharing options...

BernardC Posted February 8, 2023 Share #35 Posted February 8, 2023 The MTF is quite different, but I can only find it in a pdf on Leica's site. Maybe it's the same construction with better mechanical mounts, or maybe the glass composition is different (or both). Link to post Share on other sites More sharing options...

The difference in the mtf curves could just be the difference between measurements at 1.8 vs 2.0. The number of lens elements, aspherical surfaces (6) and special glass (3) are the same for the 35’s at least. Will have to wait and see.

Stuart Richardson Posted February 8, 2023 Share #39 Posted February 8, 2023 Rebadge or not, Leica might have designed the Panasonic lenses to begin with. They have done a lot of work for Panasonic lenses in the past. Just like a lot of Leica zooms were designed by other companies. At the end of the day, it is the results and build quality that matter. For the value minded, the Panasonic primes will be there, and for those who want better build quality, but don't want the heavy, pricey optical perfection of the APO Summicrons, they can get the new ones. I think Leica has also learned their lessons from the Summarit line of lenses too. Don't differentiate and market them as a budget line of lenses. Even if they are still great, people will instinctively not want to buy them. With these they are integrated into the lens line, and buyers can just choose the lens that suits them best. 15 Link to post Share on other sites More sharing options...
tom0511 Posted February 8, 2023 Share #40 Posted February 8, 2023 (edited) For me the Summarits felt like a bargain and real Leica lenses. Now rebadget lens for four times the price.... it is nice to have options, but it seems high in price. In the end what counts (to me) is how they deliver (IQ, speed, quality) - so lets wait and see. I was possitivly surprised by the "Leica" 24-70 SL lens and use it more often than the 28-90. Edited February 8, 2023 by tom0511 Link to post Share on other sites More sharing options...
