(1) The LCD is not articulated. My experience with Nikon and even image review on the S2, is that without
articulation, the LCD is not very useful in daylight "in the field." So, the "live view" may not be practical.
Also, the resolution of the LCD is less than desirable. I would have expected 1+ MP as a minimum. Also, note
it is not sapphire glass. The camera is 25K, so I do not believe these are too much to ask for.
(2) 50MP may be only "10 % more" IF you crop to 3:2 ratio. BUT, many compositions work as well or better
square or 4:3, in which case, you would be using all or nearly all the 50MP, so I would respectfully disagree that
50MP is not significantly better than 37 or 39. I make very large prints, every MP helps.
(3) From a creative perspective, it would be nice to have the ability to do multiple exposures as well as very
long exposures... as far as I can discern, neither is possible.
