cela veut-il dire que l'on ne pourra pas traiter les raw avec capture-one?

un détail sur lequel j'aimerai des infos quel temps de pose maximum est il possible de réaliser?

Non, le format étant le DNG. Capture One les traitera mais il n'y aura pas de profil spécifique S2 livré en standard.

32 s mais il y aussi une pose B. Je ne sais pas quel temps est permis.

je doute sérieusement que tu puisses dépasser les 800 iso, comme sur tous les autres boitiers et dos MF.

Leica was able to do binning through Maestro in firmware. They just weren't totally happy with the results, especially at higher ISO, and decided to postpone this. It may show up via a firmware update down the road. Interestingly, higher ISO can also be achieved in two other ways. The first is to slow down the read speed of the sensor output from 24 Mhz to 12 Mhz. The signal has less noise, but the frame rate would drop by half. Similiarly, the second approach is to cut from 4 channel output to 2 channel output. This also would help in reducing noise, and making matching the readouts easier as well. Just like option 1, this would also drop the frame rate by half. But, either of these approaches could potentially gain one stop of ISO. Leica is looking at the possibility of one or both of these options down the road as a firmware upgrade. My feeling is that most users would probably prefer 0.8 fps at full resolution rather than 1.5 fps at 1/4 resolution anyway.
