I briefly played around it, did not have much time really testing it but it is a very camera that people love precision instrument, photography and afford will likely want to have one, and get one. Leica without doublt produce professional quality cameras but only small percentage of its users are working professionals, but this is like many professional tools, musci, cars, many many things, a tool designed to produce professional result does not restrict non-professional to own it. I will love to have one, although I am certain I will not get one for now, but I wish well for those who will buy it, becaue it is because of them (pro and non-pro) to sustain a camera maker such as Leica to continue be an active topic.
MR did a fair review, and very useful review. For studio work, I see the S2 a strong faship camera, the tested tethered performance is not ideal, but I think it is a matter of tweak of firmware and software, it should and I beleive it will work a lot better than that.
