macusque Posted January 31, 2007 Share #22 Â Posted January 31, 2007 28/1.4 Summilux asph, thanks Link to post Share on other sites More sharing options...
grober Posted January 31, 2007 Share #23 Â Posted January 31, 2007 The front element and housing would be so big that it would block most of the viewfinder and the cost would be up there with the 400/560/800mm R lens with the focusing unit (somewhere in the $10000+ range) and just how many people would buy one. Â Ed's point is proven, of course, by the tremendous cost delta between the Zeiss and CV 15mm lenses. Â Yes, a Leica 24 or 28 lens at f1.4 is highly desirable but how practicable given the high cost it would need to fetch and also the large intrusion into the M8's viewfinder it would surely have. Â My next lens will be the 28mm Elmarit-M (to replace my current 50+ year old Canon lens.) Â -g Link to post Share on other sites More sharing options...

jaapv Posted January 31, 2007 Share #25 Â Posted January 31, 2007 The IR cut filter in the lens I think, it a must-do for Leica. And fast.... Link to post Share on other sites More sharing options...
pklein Posted January 31, 2007 Share #26 Â Posted January 31, 2007 I too would like a 28/1.4--the M8-equivalent of the 35/1.4 ASPH. But, supposed Leica came out with the rumored black & white model digital M. Because of the lack of color filters over the sensor, it would be, I suspect, at least a stop more sensitive. So what you lose on the lens end, you'd gain back with the sensor. Plus, no Bayer-pattern artifacting, every pixel is devoted to resolution, and best of all--no magenta!

frc Posted January 31, 2007 Share #28 Â Posted January 31, 2007 This is the Digital Forum, I know. Having refused my M8 when it was offered to me I don't belong here anymore;-), I know. Although this thread is not started on the Film or Customer Forum, I would like to mention that an f1.4 28mm would also be a very welcome lens to me as an available-light film-shooter. If the size would make it an intrusive viewfinder-blocker there's always the external viewfinder to help us out for framing. It would be a cool tool for indoor reportage work.

carstenw Posted January 31, 2007 Share #29 Â Posted January 31, 2007 I think I would rather have a 24/2 Asph than a 28/1.4 Asph... It would certainly be more doable. f/1.4 is rather a tall order even for a 35. How many really good ones are there in the world? 2 (L and Leica Asph)?

carstenw Posted January 31, 2007 Share #30 Â Posted January 31, 2007 If the even smaller 4/3rds system is anything to go by, the lenses are not especially small, fast or light. Â The mount-to-sensor distance on the 4/3 system is huge, around the same as Canon's EOS mount, I believe. That is one of the worst mistakes in that system design, since it forces heavy retrofocus design, which makes for large wide-angle lenses. Link to post Share on other sites More sharing options...
LJL Posted January 31, 2007 Share #31 Â Posted January 31, 2007 I am with Carsten on the 24/2 ASPH idea. That would be a great lens for indoor reportage, as well as street work. Going to f1.4 creates lots of challenges for size, cost and ultimately quality. Yep, a 24/2 ASPH would float my boat. Â LJ Link to post Share on other sites More sharing options...
Eoin Posted January 31, 2007 Share #32 Â Posted January 31, 2007 It's nice to dream and express our desires for wider faster glass, while something in the 24-28 range at f/1.4 would be ideal for those gigs in a neon lit bars and such like, I wonder how they would compare with their existing 1-2 stop slower siblings in terms of quality at smaller apertures let alone price and viewfinder intrusion. Â I guess I'm saying if Leica can give me a faster wide of the same quality at at the same price point, count me in, otherwise I'll make do with the very capable equipment I have already.

Leicaiste Posted January 31, 2007 Share #33  Posted January 31, 2007 I will prefer a 28/1,4 for two reasons:  - the 28mm frames are more confortable than the 24mm on the M8.  - the 28mm frames are available in the MP/M7 finder.

manolo Posted February 1, 2007 Share #34 Â Posted February 1, 2007 Yes please. Â Canon has a 24/1.4 FF. I don't see why leica could not make one for the M; or a 21/1.4 with a 60mm filter thread and external viewfinder. Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted February 1, 2007 Share #35 Â Posted February 1, 2007 New lenses would be for my choice 16 2.8 , 24 F2, Noctilux in 75mm F1 or even a 1.2 to replace the Lux. I would not mind a 28 1.4 but it needs to be as good as the f2 cron and that maybe tough to do . Oh and a lens that has good close focus Link to post Share on other sites More sharing options...
LJL Posted February 1, 2007 Share #36  Posted February 1, 2007 Yes please. Canon has a 24/1.4 FF. I don't see why leica could not make one for the M;  ....and it is nearly 3.5 inches in diameter, without hood, and wieghs about 1.2 pounds. And that is considered "compact" for a retrofocus design with AF. However, the edges and corners looks like viewing through a Coke bottle or something....not very sharp, even on the 1.3x cropped sensor of the 1DMkII. So, a fast wide can be made, but is it going to perform well?  I am with you on wishing for some faster wides, but at the same time, I really would not like to see the image quality sacrificed. If you use the Zeiss 15/2.8 as a referece point, a Leica 24/1.4 would probably be astronomically expensive and require an external viewfinder also. They could whip up some magic and put something out that is smaller and less costly and does deliver edge to edge sharpness, which most would "expect", but I am not wanting to hold my breath that long  LJ Link to post Share on other sites More sharing options...
jrc Posted February 1, 2007 Share #37 Â Posted February 1, 2007 This may sound a little stupid, but I don't think weight and size amount to much in a very wide-angled lens for the M8. So what it if weighs as much as a Noctilux? I carry a Noctilux quite comfortably, and it seems light compared to the Nikon lenses on my D2x. It's not like it's 20 pounds. As to size, Michael Reichmann notes on his review of a Voightlander 15mm that "depth of field runs from five feet to infinity when set at the hyperfocal distance." In other words, you don't really need the rangefinder. Â So you could make a chunky 15mm, set that puppy at X, and unless you were trying to shoot somebody's eyeball, never touch it. Maybe.

LJL Posted February 1, 2007 Share #38 Â Posted February 1, 2007 John, You are probably correct, but I do think an f1.4 aperture is going to behave differently than the f4.5 on the CV 15, no? Â I agree with you that the M lens sizes are very reasonalbe compared to any of the DSLR lenses. (I do have to carry a 1-series with a 400 f2.8 lens, and that rig is nearly 20 pounds!) The point I was trying to make is that for a lens to be that wide and fast AND sharp, it would most likely have to have a lot glass and some diameter that would interfere with the onboard viewfinder, so an external viewfinder might be needed. The only other issue that may come into play a possible problem is how to accurately focus a very wide angle lense with a large aperture and that will have a shallower DOF than something like the CV15. I have been shooting with the CV15, and while you do not really need to do much more than set to hyperfocal for distance shots, it does require a bit more effort if you want closer things in focus. Given an f1.4 aperture, I think that would become more of an issue for critical focus in closer and wide open. Just my thinking on this. Â LJ Â P.S. Just did some calcs.....a 24mm at f1.4 shooting at something 6 feet away has a DOF of just over half a foot for the 1.33x crop on the M8. That could require some accurate focusing for wide open shooting. Link to post Share on other sites More sharing options...
