wlaidlaw Posted July 11, 2019 Share #3 Posted July 11, 2019 In contrast to their weird camera, I might well be in the market for the 14-24 lens, price dependant. Wilson 1 Link to post Share on other sites More sharing options...
frank_dernie Posted July 11, 2019 Share #4 Posted July 11, 2019 I remember an interview with a Leica lens designer many years ago. He said it is easy to get the performance if there are no size and weight constraints. That 35mm f1.2 is a never-take-with-me lens. 2 1 Link to post Share on other sites More sharing options...

The 45/2.8 appears to have a manual aperture ring and I assume that the "A" setting enables in-body aperture setting as well as auto-aperture. Pete.

Looks like both of the prime lenses have aperture rings from the photos. In the days of the Panasonic-Leica FourThirds SLR lenses, they had aperture rings that were simply inert on Olympus bodies where the FT bodies were designed with aperture controls. Can't tell from the photos how these Sigma lenses work on different L-mount bodies, of course. Link to post Share on other sites More sharing options...

Pete, I have plenty of wide angle MF lenses. The SL's AF with joystick is so accurate and flexible I very rarely use MF on the 24-90 on my SL. I would imagine the same would apply for a 14-24.

It will have autofocus but I would put money on it in every other way your 50mm Summicron coming out tops, unless you want 45mm FL. 2 Link to post Share on other sites More sharing options...

Or $3,000 spare change to spend on something else... I love my 50 APO and my Noctilux and my SL50, but a compact, auto-focus f/2.8 in native L Mount is to me a good example of how right the L Mount Alliance is shaping up to be. It's great to be able to pack out one's lens arsenal without it being a massive financial decision every time.

NigelG Posted July 15, 2019 Share #18 Posted July 15, 2019 I’m wondering if the 45 could be a good fit with the TL2 + 11-23 as a minimal AF travel kit rather than my 50lux + adapter + EVF.....assuming it will work on the TL/CL Link to post Share on other sites More sharing options...
wlaidlaw Posted July 15, 2019 Share #19 Posted July 15, 2019 I was amazed to see that the 35/1.2 has 17 elements in 12 groups. This is much more like the Zeiss philosophy than Leica, whose nearest equivalent the 35/1.4 M FLE has just 9 elements in 5 groups. No wonder it is the size of a bazooka and weighs 1.1kg. The other feature on the new lenses that I find a considerable disappointment and it might even be a deal breaker for me, is on the 14-24 wide angle zoom. Because of the design of the barrel and the bulbous front element, fitting of front filters is not possible. For wide angle use for landscapes, I would very often mount a polariser and/or a stopper and/or a graduated ND or graduated coloured filter as well, all in Cokin P or Lee 100 holders. I know that Sigma have made provision for a rear sheet type filter but that is not even half an answer. Wilson 1 Link to post Share on other sites More sharing options...
thighslapper Posted July 15, 2019 Share #20 Posted July 15, 2019 Ditto ....... for me no filters means no use. The beauty of the 3 Leica zooms is they all take 82mm based filter holders making everything interchangeable. 3 Link to post Share on other sites More sharing options...
