I would suggest that this lens is "known" in the firmware, and as you mentioned maybe some dirt corrupted the reading of the real lens and the camera just thought that a lens having this "new" code was attached.

Zeiss announced a Otus 1.4/100 after the Otus 1.4/85 came out a while ago, which is also not a small lens.

The 1.0/35mm apparently coming from Zenith (isn‘t there a Switch watch brand, too? How come the lawyers let the brand names coexist?) probably obstructs more of the viewfinder‘s frames, which are bigger for a shorter focal length.

So whoever must have such an object should not give up hope imo.

The Russian lens is a Zenit. Your wrist watch is Zenith. Same same but different.

For those with an investigative mindset and/or too much time on their hands: The maximum number of possible lens codes is only 64 (2^6). Thus one could either 

a) with a lot of patience paint dummies of all the remaining unassigned lens codes and attach them to a body with the latest firmware or

b) solder an array of tiny dimmed LEDs onto a cheap experimental electronic circuit board, position them in front of the lens code sensor in subdued ambient light and try out all permutations of on/off.

One never knows, what yet unannounced Leica lens gems  might creep up in EXIF data

You need to move the lever for frame selection as well, since the lens detection and so the writing in the EXIF depend on the 6-bit-code together with the position of the frame selector.

I just tried with the coded 50 Summilux asph and the frames for 90mm - but didn't get any entry in the EXIF.

We have to know which lens Paulus used and can perhaps try with the frames.

A 90 mm f/1.5 at a minimum focusing  distance of 0.7 m, presupposing a conservative circle of confusion of 0.3 mm, would have a DOF of about one milimeter to each side of the true focus point. A very useful and much needed lens to take portraits of a single eyelash🙄. This will be difficult to achieve without EVF as viewfinder blockage will amount to total eclipse.

The downside would be the two strongmen aides needed to carry around the lump of glass for you, and the bodyguard on which the insurance company will insist due to the expected retail price😂.

Sadly, in real life, the rumour on this lens has been condensing since about June. But to each his own...

This lens will definitely hit the market next year. No doubt about that. But it will be part of the Noctilux family.

.. but EXIF says it's a M 240... it hasn't frame lever. Btw… a lens that is in the firmware ought to be also manually selectable (or not?) … my M240 hasn't Summilux 90 in the list (but I probably haven't made the latest FW update )

OK, then it is 192 [ 3x(2^6) ] options. Will have to wait for the weekend😂

Noctilux AS COST ZONE…  but the "official" Leica Poster baptized it as Summilux… which is logical given the aperture...

Yes, but even without a frame lever, there is an internal selctor for the frames, which is triggered by the lens. And even if the code of the "90mm Summilux" was read due to some error of the coding, the right frames for 90mm must have been triggered as well, otherwise a 90mm lens could not show up.  

There are some hidden entries for lenses in the menu. I think it was 01av who found an entry for a 14mm lens long ago, which has never materialized since. Rumors about the 90mm Summilux came at the same time when the 75mm Noctilux was presented.

Yet the absolute aperture (entrance pupil) would  nicely fit into the nocti range:

50/0.95 = 53

75/1.2 = 62

90/1.5 = 60.

Yet, I agree that the EXIF data in this post, the lens poster and the recent rumors all point to a „lux“ designation. It may depend on what retail price their marketing department would find achievable. Or, they already have a 32 element 5 kg 90/1.1 on their drawing board

It’s simply the last information I have from an official Leica employee. But I couldn’t care less. It’s far away from my desired focal length.

I like to always carry a tele with me outdoors, but I find my Apo Summicron 90 asph not lacking in any respect. And that one is at the upper limit of weight/form factor that I personally find acceptable on an M. Moreover, DOF with 90@f/2 is already thinner than with 50@f/0.95.

[luigi bertolotti]

90 mm is personally a focal I have always used a lot…  but (apart obvious rea$on$... ) cannot imagine how could I enjoy f 1,5... still have never been confident of using my Summicron wide open…

True… which makes to repeat our question to Paulus… which lens had you on ? Which frame did you see in the VF ?

 

[lct]

At full aperture, a 90/1.5 lens would be out of the accuracy range of all Leica rangefinders but M3 and 0.85x M6 i suspect. Better use an EVF or a magnifier with such a lens.

Just happened to see this in Lightroom, I don't know what it means.

It probably means the camera got the 6-bit code of the lens wrong. Maybe the lens wasn't properly attached; it didn't fully click into place or it was slightly beyond the proper position in the mount, so the code wasn't recognised correctly. Which lens did you actually use?

In any case it means that the rumour about an upcoming Summilux-M 90 mm 1:1.5 Asph is correct. Obviously the camera's current firmware knows this lens yet. And no, it won't be part of the Noctilux family. Noctilux lenses are members of the Noctilux family; this one is going to be part of the Summilux family.

No. What would be the point? For example, the 28mm Summaron-M is not in the list of my M9... because all 28mm Summaron-M lenses are coded. I guess only older lenses of which uncoded examples exist are manually selectable. This makes sense.

Why do you keep repeating what has already been posted? What is the point? Do you think that the exif data magically changes because you open it on your computer?

[ianman]

Looking again at the exif data, something is bothering me.

It indicates "Summilux-M 1:1.5/90 ASPH." and yet, when I look at all the other coded lenses, the nomenclature is different. In the list provided on this page, the nomenclature is familyName-M + focalLength + maxAperture + info. With this "new" lens, it is quite different with the maxAperture preceding the focal length and being written 1:1.5 instead of the f/1.5 format. Taking the standard notation format, the exif should read: "Summilux-M 90mm f/1.5 ASPH."

This may be nothing, or it could be that someone (not mentioning any names here Paul 😉) is playing an elaborate joke. After all, it's very easy to modify a files exif data.

Hallo,

Look here: Leica M
