Thanks Guy for all this insight.
Indeed MF is a different beast and we should know that. I am aware of that and I am maybe in the very lucky situation that I do not have any of these systems right now and can choose from the scratch. So for me there are 2 fixstarters (Hassi and Phase ) and then there is the S System - maybe.
It finally will be also a price decision for me and of course availability and trust, as Leica as a company with their products has let me down very often - in several areas. And yes, maybe you are right and they do a lot of processing and correction already in the body of the S2 and not in external SW.
It was the post processing I saw yesterday first time for MF and it just cam to my mind that I would not like to do all these corrections manually, but decide for a certain lens which corrections to apply automatically and whenever a photo taken with that lens is imported, the SW applies these corrections automatically. It does not make any sense to me, if I prefer SW edge sharpening plus CA, then to do an individual select by photo.
But as I also mentioned, maybe this is a bit too hysteric and I should not pay too much attention.
Finally I was (am) very pleased with the results and I also learned one thing for sure - for the moment I can survive with 39MP and this makes back prices much more interesting - be it Hasselblad or Phase
Please continue commenting here, I am learning incredibly much from all of you!
