Current 35 'lux ASPH price is $4,495, so not that big a jump. "Bigger" and "floating elements" - not for me - but maybe it will produce some used stocks of the current (for the moment) design.

 

Kinda hard to believe, but the 35 'lux ASPH is actually the oldest lens design Leica currently makes for the M except for the 50 f/2.

Well, I have a 50 lux asph and well as a 35 lux asph. while they render differently, the 35 is certainly no step-child to the 50 -- yes, i am lucky, my version has no material focus shift. so while the new 35 will draw differently than the current version, i don't believe it will render better than the current version, focus shift aside. but had i not been fortunate enough to own an excellent 35 lux and was in the market for one, i sure wouldn't plunk down 4300 for a lens that might have the dreaded focus shift (even if the problem is greatly over exaggerated).

Jeff, there just seem - emphasize seem - to be some problems to the FE designs so far that pop up again and again. Either stiffness in the focusing due to the extra helicoid, or oddball focus problems. I explained my gut feeling in response to this thread: http://www.l-camera-forum.com/leica-forum/customer-forum/111976-summilux-24-backfocus.html

A local store has a used 75 'cron that simultaneously back-focuses at infinity and front-focuses at 1 meter or less. And seems to have more CA than other samples I've seen. I just have this sneaking suspicion that the FE helicoid has jumped its track by one thread.

 

As nice as these lenses are when they are behaving, I just don't trust the FE systems to stay aligned and tracking with the rest of the lens. At least for RF use.

A new Summilux makes sense and the 35 is the oldest Aspherical lens and the oldest Summilux in the lineup. At the same time the 75 Summilux was disccntinued without replacement. There may be more of a gap here than in case of the 35 mm. Sure enough 35 mm is the prime lens of RF cameras, so it gets updated more often - assuming that image quality can be improved. Let's wait for a Summilux 35 and 75. It will happen eventually, the question is when.

Gentlemen -- may I humbly point out that (a) it is a forgone conclusion that a new version will come soon, (B) that -- given (a) -- improvements will be made, © that the most urgently demanded improvement is elimination of focus shift, then (d) this will entail floating element construction, because that will be less expensive than two ground and polished aspherical elements, and (e) such a lens, being more complicated than the present version, will be (1) slightly larger, and (2) cost more ... what's the to-do about? These are the plattest of platitudes, the truest of truisms.

 

I am already in line for the lens. There are more interesting questions to discuss, such as ...

 

• Will there be a new 50mm Summicron ... or will Leica Camera conclude that four 50mm lenses are one too many?

 

• Can anything be done at 135mm, where Leica provide finder frames for a lens they say can't be used at full aperture?

 

• Will they produce a 28mm Summilux? ...

 

• ... or/and a 21mm Elmar?

My own impression is that the present line-up of Leica lenses is already overcrowded with the minimum of 2 versions from 18 to 90mm and already three versions for focal lengthes which are not in the center of customer's demand (i.e. 21 and 24mm).

 

So it would surprise me if they introduced any additional versions which aren't already represented today.

 

A new 50mm Summicron will depend on the costs/price ratio of an aspherical version. If they can realize it under 2000,-€ we might see it, if it would cost more, the Summilux would always cannibalize it.

 

28mm Summilux seems to be a gap, though it would reduce sales for the 24 and 35luxes causing Leica more trouble with producing different expensive versions for one and the same sector of the market. I stay sceptical.

 

21 Elmar - only if they kill the Wate. I don't see a real market for 4 Leica 21mm lenses besides the different Zeiss and CV versions. The M9 reduces demand for wide lenses.

 

75mm-lux: only if Leica likes many more threads over here and elsewere with people complaing about mis-focus etc, etc.

 

Lars' question about 135mm seems to be the most interesting one. I am sure they won't get back to the idea of a goggled version. To reduce the present formidable Apo-Telyt to a 4.5-Hektor would make no real sense - just to tell people: now you can use it wide open??? There might be some option camera-wise with a bigger magnification of the viewfinder like the 0.85-version for film-Ms. Though I think the market is too small and still too many cheap and good second-hand 135mm Leica lenses around to stir much interest on the producer's side.

 

I rather see a pause for several years for new revelations of M-lenses. There are other fields to care for by the optical department (S, X, and perhaps post-R).

Especially as the "impossibility"of using the 135/apo wide open seems to be rather conservative, to say the least. Users report no problems at all, rather the contrary, simple to focus on the M9 wide open.Unsuprisingly, as the DOF difference to the 4.0 versions is small, and those are "approved" by Leica.

Well, I'd prefer to stay conservative with my reports - though I don't know the M9 and Leica's recommendation to stop the lens down should not be understodd as them saying it is unusable wide open.

The primary reason I linked to post is that there was an estimated arrival date and price, whether right or not. The rest, as you say, was already beat to death.

 

No matter to me...35 Summicrons have sufficed for decades.

There was already a new Summicron 50. But it was too expensive to manufacture, too heavy and IQ-improvment was only marginal. The 35 SLX asph. then was made based on this optical formula and knowledge.
