Engadget - Remember the NEX-7? Ever since a days-long shooting session back in September, Sony's prized mirrorless cam has eluded us -- and the rest of the world. As you may recall, the flagship Alpha ILC was hit by the Thailand floods, resulting in delay after delay, eventually missing the holiday shopping season entirely before resurfacing late last month. Another week later and our beloved Sony Alpha NEX-7 has finally arrived, ready to take on the streets of New York City. So what exactly is the NEX-7, and why does it cost as much as a mid-range DSLR? First off, the 24.3-megapixel APS-C ILC captures, well, 24.3-megapixel images, offering the highest resolution of any mirrorless model on the market. Its APS-C sensor is identical to the one found in Sony's A77 DSLR, measuring larger than Micro Four Thirds and on par with most full-size digital SLRs.
