Stefan-S Posted December 27, 2009 Share #21 Posted December 27, 2009 Advertisement (gone after registration) What about a googled 2.8/180 apo asph? And a TATE 4/75-90-135? Link to post Share on other sites More sharing options...
Advertisement Posted December 27, 2009 Posted December 27, 2009 Hi Stefan-S, Take a look here Most Likely New Lenses. I'm sure you'll find what you were looking for!
Ivar B Posted December 27, 2009 Share #22 Posted December 27, 2009 If I were a gambling man, I would bet on a new 50mm Summicron ASPH, as both the 50mm Noctilux and the Summilux lenses are now aspherical. This would seem to be the most logical move for Leica, especially in view of the full-frame M9 introduction and the 50mm being a "normal" focal length. Anybody for starting a "next lens" pool? I asked Stefan Daniel the very same question, and he replied that he had asked the designers the very same question. The reply was apparently that - yes, there is no problem with improving the 2/50, but not without a considerable increase in cost. If the 2/50 were to cost as much as the 1.4/50, I doubt that many would buy it. We also learnt that the 1.4/50 far outsells the 2/50. Link to post Share on other sites More sharing options...
novice9 Posted December 27, 2009 Author Share #23 Posted December 27, 2009 And the performance of the 24 is not exactly stellar, say user reports. Which user reports are those? Funny, everything I have read from users states the lense is indeed stellar. Would be very curious to see where these reports are, if you wouldn't mind pointing me in that direction. many thanks.

Well, Ivar, I guess that settles that, so I am now officially out of the "fortune telling" business. Thank you for this first-hand information. It is interesting to note that the much costlier (by 80%) Summilux is outselling the less expensive Summicron. Now, who wants to make the next guess?

Ivar B Posted December 27, 2009 Share #26 Posted December 27, 2009 John, I only say what we heard in May, but at the time we also learnt that there would be no full frame digial M any time soon, which was clearly incorrect, so who knows. Stefan Daniel did indeed say that he thought the M lens line up was more or less complete, but that they were looking into the 1.4/35 ASPH due to the focus shift problems.

rosuna Posted December 27, 2009 Share #27 Posted December 27, 2009 Advertisement (gone after registration) The Summilux 75mm never was a top seller. A new Summilux 75mm ASPH may be smaller than the old one, but I think it is difficult to reduce the size including floating groups. A lens so fast may be difficult to design with APO specifications.

novice9 Posted December 27, 2009 Author Share #28 Posted December 27, 2009 Would Leica Camera do? Just look at the MTF curves. The old man who survived the Age of Hype Yes, but you said user reports. All user reports I have seen reflect that the lens is indeed stellar. Link to post Share on other sites More sharing options...
Marty Posted December 27, 2009 Share #29 Posted December 27, 2009 About the necessity of f1.4 - even if one is not convinced by the light-gathering benefits, the beautiful way the Summiluxes draw wide open is unlike any other aperture. Link to post Share on other sites More sharing options...
UliWer Posted December 27, 2009 Share #30 Posted December 27, 2009 Would Leica Camera do? Just look at the MTF curves. I just had a look. The MTFs for the 21/24 mm Summiluxes are not really much worse than those for the current 35mm Lux Asph. - in some respects you could call them better.

The old man who survived the Age of Hype A photograph of MTF curves looks like s**t anyway. The images of real objects, though, look pretty darn good. Seriously, MTF is just a part of OTF, which makes it rather limited as a quality parameter. Link to post Share on other sites More sharing options...
UliWer Posted December 28, 2009 Share #33 Posted December 28, 2009 Ah - that's what you mean by 'stellar'. I'd call it 'acceptable'. The old man who suvived the Age of Hype I did not call it "stellar". Though I might call it acceptable if a 21 or 24mm lens at 1:1.4 showed MTF-curves similar to a 35mm which has always been regarded as very good.

Do you think you could explain a bit more what you mean by this? What is OTF? Link to post Share on other sites More sharing options...
jaapv Posted December 28, 2009 Share #35 Posted December 28, 2009 OTF is Optical Transfer Function. MTF is a contrast/resolution (frequency) graph that is calculated in the focal plane only. Drawback: It does not say anything about the rendering of spatial objects, as most photographic objects are, nor about the rendering of OOF areas. Those are just the things that are important for a super-fast wideangle, thus the MTF curves don't say much about the Summiluxes 21,24 and 35. Nor can it be compared for different focal lengths, or even different brands of lens. OTF is a three-dimensional of describing lens performance. The problem is that it can only be evaluated by real experts, certainly not by me, and is thus seldomly used. Link to post Share on other sites More sharing options...
novice9 Posted December 28, 2009 Author Share #36 Posted December 28, 2009 Thanks. So then is it fair to say that the contrast and resolution of the 24 regarding in-focus areas of the image are fairly mediocore (as per the MTF charts) and not as good as the 21?

Bo_Lorentzen Posted December 28, 2009 Share #37 Posted December 28, 2009 Good Grief.....! Guys, who cares about MTF charts, lets get back to photographing with these lenses Ultimately these lenses are as good as the guy pointing the camera. and if that guy need shockingly thin focal plane on a 21mm - well then this is the ticket. Personally I am more concerned with the physical size of the new crop of lenses, and am likely to pick slightly slower lenses to get something more pocketable. .

thrid Posted December 28, 2009 Share #38 Posted December 28, 2009 I would put my money on... Summilux-M 1.4/28 ASPH This should be a no brainer, but it will probably cost as much as a kidney transplant. Revised Summilux-M 1.4/35 ASPH Based on the Lux-M 1.4/50 ASPH, with floating element. From what I know they are related. What I would also like to see: 4/28-35-50 Tri-Elmar ASPH Sure would be nice to see this lens return to the stable...

Summilux-M 1.4/28 ASPH This should be a no brainer, but it will probably cost as much as a kidney transplant. ... I don't see a 28mm Summilux. It would cannibalize the 28mm Cron and vice versa. As it isn't so improbable that we might see a new Tri-Elmar 28/35/50 this would mean Leica had 4 lenses with 28mm. It's obvious that Leica has problems to keep the production of their already large variety of lenses in line. So I think it would be more reasonable to substitute current versions with new ones than to add new types. Link to post Share on other sites More sharing options...
