Seems to be a bit larger the 28mm Summicron

The area that hits the rangefinder mechanism of the camera looks different. Probably part of the mechanism to reach the assumed minimum distance of 0.3 m?

My WATE is the only lens that goes below the usual 0.7 m for M lenses and you can feel a short but obvious resistance in the spiral walk when focusing below 0.7 m.

The M rangefinder is limited to 0.7m - or a tiny bit closer - regardless of the lens used. The apparent increase of the lens movement to 0.3m is for use with EVF/live-view.

The "resistance" in the WATE (and probably this lens) is mostly there to remind RF users that the RF is no longer operational and trustworthy past that point.

(I also wonder if it actually takes another half-turn of the focus ring to get down to 0.3m from 0.7m - that may be Photoshop-fiction just to make the new feature obvious in the illustration).

Leica has been - variable - in whether the focusing cam is brass with visible threads, or a plain black structure, with or without visible threads. At least as far back as the original Summarit set (2007).

It is also interesting that there is now a knurled focusing ring, and not just a tab on the numbered ring. Leica did that once before, on the brief-and-rare 35mm f/1.4 Aspherical. Again, that may have to do with the extended focus range. Because at 0.3m, the "tab" would be on the top of the lens, and hard to access with a finger-tip anyway.

The far protruding rear lens - or just it's edging - looks strange.

If it's real and not a PS mock-up I'm thinking Italian Flag since it looks like the rear element would very close to the sensor.

I just looked at my 28mm Summicron: the rear element protrudes as well - other than shown on the photo in #104 - though not as much as shown in the "photo"(?) of the new 35mm. 

A close rear element must not necessarily cause the "Italian-flag" problem. The diameter of the exit pupil is most important.

RE: rear element protrusion. Don't panic, people! (Geez!)

- Any reason it would not fit (with the standard added depth of an M-TL adapter) on a CL?

- I believe "Italian Flag" problems** depend on the position (not the diameter) of the exit pupil. And in any case, this is a 2021 lens - it will come from the factory with 6-bit coding (and associated firmware upgrades).

- Since I credit Leica with more intelligence than, say , the average field mouse, I am sure they know exactly how large their rear caps are, and engineered this lens for compatibility . ;)

- Just for reference, here is a full-length portrait of the current 35 Summilux FLE - looks like the APO-Summicron protrusion is within 1mm of the same.

** For newbies not aware of Italian Flag syndrome - it refers to reddish and greenish/cyan stains on opposite sides of full-frame color digital pictures made with wide-angle Leica M lenses. Which Leica has fixed ever since 2009 with the 6-bit lens-ID coding, and in-camera firmware-processing adjustments based on the "known-lens type."

2009 picture with coded 21mm Elmarit, but "not quite ready for prime-time" original M9 firmware.
