Interesting . Wonder why the price changed back or maybe I just looked at the bp-scl7… for sure on the bp-scl7

Yes, the BP-SCL7 is $380, which is more relevant here, given it’s for the M11. The BP-SCL6 is for the SL2/3, Q3/43, etc.  Sorry for any confusion.

It seems like the M11-Series firmware update is obsolete soon, just like the M10-Series. It’s not fair that M10 and M11 customers won’t get any further updates.

I am wondering what 'new tricks' the cameras can do. In my experience, up to the M10 (I don't have an M11) they are all working beautifully. Even as far back as my M8's, no issues. So what benefit could I expect from upgrades?

More M lens codes supporting Elmar 50mm F3.5, Summaron 35mm F2.8/F3.5, 90mm F3.5, 135mm F3.5 and more...

I'm not aware of Leica 90/3.5 or 138/3.5 lenses, but Elmar 50/3.5, Summarons 35/2.8 or 35/3.5, or Summarit 50/1.5 have never got a Leica code since they were long discontinued when 6-bit coding has been implemented. However a good question could be to know if owners of discontinued bodies are entitled to claim for firmware updates about new Leica lenses that did not exist yet when their body has been discontinued.

So why do manual lenses not also have this hot focus issue? Is it perhaps just long focal length lenses?

Manual lenses certainly do show this issue. Lots of manual fast, long lenses (e.g for sports, wildlife, etc.) were designed to focus beyond infinity as they were developed (1970s). 180 f/2.8s, 300mm f/2.8-2.0s, 600mm f/4s, etc. They could not reliably focus to infinity otherwise.

Yes, physical length plays a role, since the change is caused by the coefficient of thermal expansion - which is a multiplier or percentage.

I.E. if a metal lens tube 15mm long will expand .01 mm with a temperature increase of X, then a lens tube 600mm long, of the same metal, will expand .40 mm with the same temperature change X.

Interesting that plastics/polycarbonate have higher CTEs than brass or aluminum - may explain why certain plastic AF lens barrels need more - leeway - (more overshoot available) than M lenses.

The advantage of composites is that the designer can control the expansion of the barrel by structurally combining materials with different expansion coefficients. There are experiments  ( probably not (yet?) in lens design ) with heat-shrinking material. This is of much interest for my field of dentistry as the shrinkage and expansion of composite filling materials is a real problem for the longevity of fillings. 

M lenses reduce the problem by fixing the optical cell to the rear of the outer barrel, thus limiting the expansion to the inner barrel. With longer and more complex lenses this is not feasible.

Im curious if the M11-V allegedly will use the same maestro 3 sensor like other M11 series since the visoflex is probably a good example how much it can take in terms of liveview capability, it’s still limiting compared to what’s on the markeT

The Maestro 2/3 processorsshould be capable of running EVFs - Leica SL and Q cameras had proven this since first generation. But probably the Visoflex is using a less performant interface (or the bandwidth had been dialed down for reliability or power saving reasons).

The original Visoflex of the 240 could not be upgraded to the newer and better Olympus made by Epson variant as Leica could not get it to work through limitations in processing power. Before blaming Leica, at the time the firmware was provided by a division of Zeiss. A large division that even provided the weapon systems software for F16 fighters.

Of course.. just how good the experience on M11 i wonder

The two biggie reseller in Ny had them in stock on evening and in stock the next morning. The just made a buttload more profit!

They won't make any profit unless they sell them 😁 I don't imagine anyone will be buying a battery for $380 that wasn't worth the $200 it was before. Most will wait to see if/when the tariffs are reduced or lifted.

[...] Additional M lens code request for Summarit 50mm F1.5 and Elmarit 24mm F2.8 if possible.

There is no specific 6-bit code for the Summarit 50/1.5 that was discontinued in the 60s if memory serves. It has similar vignetting as the Summilux 50/1.4 v2 AFAIK so it can be coded as such (000101) presumably. I have no experience with it though. As for the Elmarit 24/2.8 asph its 6-bit code is 011001. See coded flange below. FWIW.

What specifically?   Just updating for updating's sake would be meaningless.
