Our friends at Popular Photography just posted a thorough test of the thoroughly awesome Sony A77 DSLR, the better-in-every-way followup to last year's A55, which PopPhoto actually declared the Camera of the Year. It's got a brand-new 24.3MP sensor, the world's first electronic OLED viewfinder, and, most satisfyingly, an overall rating of Excellent in PopPhoto's tests--no mean feat. Oh, and it's $200 cheaper than competing Nikon and Canon models. Read the full test here.
