i've spent hours yesterday with a friend's camera and something struck me that i didn't notice earlier when i first saw in store...
the 4 buttons above the LCD on the top are now micro buttons compared to the big round buttons on the Mark II
the previous buttons seemed to be more qualitative and left no space, therefore gave the impression of better weather sealing
the touch was also more accurate, more comfortable
on the Mark III, these have become "micro buttons"
quality of manufacturing seems lower and they do leave a huge space, enough to get dust or sand inside...
and the touch seems less easy than previously
to actual owners, how do you feel about this ?
