Crazy good camera. Went from 7D and 5D Mark 2, regretted nothing. If you are tired of dragging on a big and heavy DSLR, this is a clockwise choice! Less than I thought fit in the pocket of the winter jacket without any problems. Taken on a SIgma ART 30mm f / 2.8, the bell photos become. Cruel image quality, easy to handle, very smooth, quick AF .. Where are the disadvantages? :) The live view mode is so pretty well compared to Canon's junk mode which is so incredibly slow. Rotate screen is really good to have, personally does not touch it. Will NEVER go back to the mirror camera. No problems with the sensitivity and function of the buttons, they are good and work well in my opinion, but not professional photographer.
