jaapv Posted June 12 Share #121 Posted June 12 Advertisement (gone after registration) The lenses I miss in this discussion are the Zeiss ZM lenses They seem to have faded into the background a bit but some render quite unique. For instance the Distagon 35/1.4 is an unique lens that provides a kind of transparency that no other lens does. 1 1 Link to post Share on other sites More sharing options...
Advertisement Posted June 12 Posted June 12 Hi jaapv, Take a look here SL 28-70 f2,8 on June 12?. I'm sure you'll find what you were looking for!
sebben Posted June 12 Share #122 Posted June 12 Would love for Zeiss to join the L-mount alliance. I don’t understand why they aren’t already in it. Zeiss I feel gets the rendering best despite all the technical mumbo jumbo that people like to judge lenses by. 2 Link to post Share on other sites More sharing options...
beewee Posted June 13 Share #123 Posted June 13 (edited) 9 hours ago, SrMi said: From DPR: "The optical design is remarkably similar to the Sigma Contemporary 28-70mm F2.8 DG DN lens. However, given that the MFT charts are substantially different, the two lenses seem to perform differently." This has been removed and as someone in the comments noted, they’re actually quite similar if you look at the 10lpmm curves which both Leica and Sigma published. The other curves differ because Leica publishes MTF curves for 5/10/20/40 lpmm whereas Sigma publishes curves for 10/30 lpmm. If you linearly interpolate between Leica’s 20 and 40 lpmm curves, you’ll get something remarkable close to Sigmas 30 lpmm MTF curves.

Sigma's Contemporary lens only offers weather sealing at the mount, not throughout the lens." Probably worth paying extra for us at least 🫠 That may be true for you Seb, but I don't live in Iceland anymore. I live in denial. 2 Link to post Share on other sites More sharing options...

Jeff S Posted June 13 Share #127 Posted June 13 Advertisement (gone after registration) The guys from Leica Miami have tested the new lens against its Leica siblings (24-70 and 24-90), and will discuss their findings in tomorrow night’s episode of Red Dot Forum Camera Talk on YT.

Sure, but they will do a live demo with test shots for others to judge (to the extent that shooting charts and teddy bears matter). 1 Link to post Share on other sites More sharing options...
scott kirkpatrick Posted June 13 Share #130 Posted June 13 How does DPR know the optical design shapes and MTFs for the new 28-70? I can find a sketch of the lenses but no MTFs on Leica-USA's site. I have some situations where a light zoom would serve. The hefty sized 24-90 has never appealed and gives pretty weird distortion at the fairly wide end. Looking at charts it seems its outstandings are concentrated at the long end. If this new fellow is really a beefed-up, rebranded Sigma, I'd just want to know if it is a GOOD Sigma.

jaapv Posted June 13 Share #131 Posted June 13 The sigma donor design is a very good lens, clearly designed to be a daily workhorse. Link to post Share on other sites More sharing options...
kiwidad Posted June 13 Share #132 Posted June 13 Yes absolutely! Already sold my 24-70 aka back breaker and use a 20-60 as a stock lens and if I need low light theres always the 50 or 85 1.8 lenses The size and weight and range of this lens (show 28-70 for years on 35mm) mean less back pain at the end of the day for me!

All zoom lenses that don't do EVERYTHING internally breath in foreign particles at least thats been my experience even with leica stuff! Link to post Share on other sites More sharing options...
Jeff S Posted June 13 Share #134 Posted June 13 (edited) Yup, I would have preferred internal zoom with 28-70, even with higher price, although this would have lengthened the barrel. Edited June 13 by Jeff S 1 1 Link to post Share on other sites More sharing options...

My experience differs, with outstanding performance throughout the range after processing as normal in LR Classic (and ImagePrint) and viewing my prints. If anything, I found the 90-280 (now sold) marginally better at 90, but with no practical difference in prints. The lens also has OIS and better close focusing ability than even the latest close focusing M lenses. I sold my SL75 APO as well and use this lens as my workhorse on the SL2 as a complement to my M system. Couldn’t be happier, other than size and weight (and lack of internal zoom), but a whole lot more compact and less expensive than carrying 6 primes, or even two. Different strokes. 1 Link to post Share on other sites More sharing options...

Maybe the added new rubber gaskets around the extending part of the barrel to stop dust that are not present in the Sigma version... Link to post Share on other sites More sharing options...
TL3 Posted June 14 Share #138 Posted June 14 I like the red dot forum testing videos, they’re pretty informative given that they probably only had a few days to come up with it. I have to give them props, they are quite good at spinning lower performing lenses into something positive, and encouraging my GAS. Link to post Share on other sites More sharing options...

They will take 2 hours of your time after which will not be smarter, but may feel better. Edited June 14 by la1402 2 Link to post Share on other sites More sharing options...
