Mega-megapixel! Meet world's highest resolution DSLR

LOS ANGELES- Camera manufacturer Canon is taking a leap of faith that photographers want even bigger files, and way more resolution than they're used to getting.

The company in June will release updates to its beloved 5D Mark III camera that ups the resolution from 22 megapixel up to 50.5. Two new models, the 5DS and 5DSR will sell for $3,699 and $3,899.

The cameras are aimed at pro photographers who shoot advertising and other commercial work that ends up on billboards and the like.

This is a major move for Canon, as the 5D Mark III found its popularity with both pro wedding and event photographers, and more vocally, filmmakers who started using the camera to replace camcorders. The image sensor on the 5D Mark III is 20 times the size of that of a camcorder, and provides a sleek, cinema look for video.

The current file size on an uncompressed photo in the 5D Mark III is 15 megabytes, so the new files will easily be 30 megabytes each. Photographers buying the new 5D camera will want to spring for extra hard drive storage along with the camera.
