thank you for this great review and the guide how to get the most out of this camera.
I think that user experience with M11(M) and now Q3 (ie with 60MPs sensors camera) may indicate:
M camera version with in-build electronic viewfinder and image stabilisation (IS) would make it better, even stronger work horse when coupled with sensor of 60+MPs. It would provide up to 5 stops improvement related to “ISO performance”. I note you hardly use shutter speed slower than 1/320s even with 35mm lens, to ensure sharpness of final pictures. With in-built IS up to 5 times lower ISO setting could be used to achieve yet better results in low light situations – one of key selling points for this camera. I note that to ensure tack precise focus you also relied mostly on use of EVF given details that 60MPs sensor can reveal and is made for. In the low light situations where this camera offers the main competitive advantage EVF is a must for focus anyhow. Even if RF had to be eliminated from such a camera it could still be called “M” for “manual”. I note that many photographers use M lenses on SL cameras (for small factor and weight advantage these lenses offer compared to their SL counterparts) and appreciate focusing and IS mechanism of SL bodies. This coupling I believe is suboptimal solution (perhaps splitting hair a bit here for most use cases) in the world of Leica where we pay hefty premium for excellence to be achieved via M lens – M body matching manufacturing perfection. I would not hesitate to bet on that demand for such camera would exceed that for M11M and hence no bigger risk for Leica company business to take than they are used to taking already…

I shoot 2/3 of my work in black and white, but own a M11 and still don’t know if this investment worth the financial effort or maybe saving my dollars for the future SL3 (2024) is a wiser option.

Here, I’m just referring to the exposure slider in Lightroom. Each whole integer number represents one stop. So, if I’m pushing 3 stops that means that that exposure slider is set to +3.00. Hope that clarifies.

We talked about diffraction limits with the 60MP sensor on our Red Dot Forum Camera talk M11 Monochrom episode. Definitely best practice to avoid stopping down past f/5.6 for most shooting on the M11M. I found that stretching to f/8 for times I really needed the extra depth of field was still okay. But for sure, I would not recommend f/11-f/16, as there will be noticeable diffraction and softening of details.
