I've been using a couple of Nikon APS-C format cameras for several years now.
My newest is the consumer level model D3200. It's 18x24mm sensor has a pixel count of 24.1 meg. At regular ISO levels and in a variety of situations, it delivers some of the sharpest images I have ever seen in my own work.
One of the things I had yet to try out, tho, was the high ISO mode.
