The 600D is feature rich, pleasant to use and of course takes beautiful photos, the value is impressive and it is hard to be disappointed by such an apparatus. I own the 5dII barrel and before I had the first 5d and I must say that the 600d is almost as good as with the addition of HD video. From 100 to 800 ISO we see little difference with the full 5dII format. MOST / 'Excellent image quality, even at high ISO settings. Dynamic Good, enhanced by the use of highlight tone priority. 'Articulated LCD perfect for video and the macro level with the ground. 'Ability to remotely control Canon flash units in slave mode. '1080 quality video with an external microphone jack. 'Good battery life and comprehensive software suite (RFP ...) LEAST / AF slow screen mode and no tracking AF in video. no AF micro adjustment, very annoying with all these problems back and front focus increasingly common even on L barrel, yes! 'Custom functions somewhat complicated and often useless, especially for a beginner. (I had mistakenly programmed the lifting of the mirror for a few minutes and I thought the unit failed) 'Raw lack a direct dial button and the second experts devices while the DISP button on the top does not serve me, cannon engineers should follow the Pentax K5 for example on the position of depth of field test and other . 'A little small for large hands, advised grip.
A final tip: In video mode do not forget to disengage the stabilization because of the noise it generates.
