D3100 is missing some features I loved about the D5000....
29 November 2010
Summary: I already own a Nikon D5000 and ordered the D3100 because of it's lower light capability and better HD video capability. HOWEVER, I was disappointed that some of the features I loved about the D5000 have been omitted with the D3100. The D3100 has no "scene" mode - ideal settings for beach, snow, autumn leaves, pets, etc. This mode was replaced with a "guide" mode... not needed if you refer to the manual and if you are familiar with the camera.
Summary: its a very compact camera in the dslr range, about the same as the d3000 or d5000 in weight and dimensions. but, the features on this beginner level camera are amazing. id highly recommend this camera to anybody who wants to move beyond point and shoot into slr. for a camera that was supposed to be equal to canons xsi, this is amazing. 1080p video, high ISO ranges, sleek body design, and a 14.2 mp sensor makes for a great camera, even for professionals.
