True, but I argue that focus distance is actually more important. Simple geometry dictates that the closer the subject the more any movement will negatively impact the result. It's easier to shoot a 50mm at infinity and 1/25" than it is at the same speed with a 28mm at 3 feet. Link to post Share on other sites More sharing options...

It is something that I noticed with IBIS effectiveness: it depends on the subject's distance. FWIW, an effective IBIS needs focus distance, which is a problem with M lenses. Here is an interesting post by k-hawinkler on GetDPI about the effectiveness of IBIS as it relates to subject distance. 1 Link to post Share on other sites More sharing options...

Precisely where I learned that lesson as well. IBIS is far more effective at long range... one can often hand hold effectively for multiple seconds... but focus at minimum distance under similar lighting, if you rely solely on IBIS without using proper technique, it's virtually useless. 1 Link to post Share on other sites More sharing options...

Thank you so much for your kind words.🌿 50mm f/0.95 ASPH Noctilux-M, M11 This shot is inspiring me to shoot with more with this lens. I have not shot my Nocticlux 50mm /0.95 on my M11 yet. I've been only shooting it with my SL2 because of the focusing ease. I'm going to try on my M11 with the Visoflex this weekend.

Excerpt from your link: « In the case that the lens does not provide electronic communication, the user can manually enter in the focal length. But in that case, the camera can still only have the focal length input, and not the focal distance » Sure but it's still better than no IBIS at all no?

However, it is not feasible to get the best possible stabilization without the focal length information. I wonder whether SL2 owners see a significant reduction in stabilization when they use M instead of L lenses. Link to post Share on other sites More sharing options...

Effectiveness of IBIS also decreases with focal length, so quite a few variables at play. IBIS on my SL2-S is rock solid w/M lenses at close distance, though. It makes a huge difference for me 🤷♂️ Link to post Share on other sites More sharing options...

As I see it, the 60MP BSI sensor was just considered to be the best option. I do get the sense that there has been a change in the decision making for the M system. The pixel binning seems to me to be a compromise to deal with handling the increase in pixels. To my mind, that signals a shift for the M digitals from reasonably accepted and stable technology to the more adventurous, bleeding edge end of tech. While I am comfortable from what I’ve seen and read that achieving sharp images isn’t the problem many of us feared, the M11 still feels like a odd development to me. There is much to love, but it’s almost as if Leica added the big capacity sensor, then had second thoughts. 2 Link to post Share on other sites More sharing options...
Jeff S Posted May 14, 2022 Share #499 Posted May 14, 2022 Technology seems to be increasingly driving specs and marketing (including pricing) in top end Leica M products. We see this in top M lenses now, too, as a Leica presentation revealed that the 35 APO M Summicron was initially spec-ed with the standard 70cm MFD, and only later in the development process, the tech side of the house said that 30cm could be achieved. The process was halted and the lens design was reconfigured, and no doubt the price point was adjusted. Who knows if Leica can now meet the demand and maintain quality and reliability while pushing the tech envelope (in a very compact M package). But maybe we’ll eventually see how this was meant to integrate, as even more new tech allows, and as overall product lines evolve. Jeff Link to post Share on other sites More sharing options...
