Canon sharpens its image with 5DS R (hands-on)
The 50-megapixel models in Canon's EOS 5D series of full-frame cameras aren't expected to ship until June, but Canon released some preproduction versions, one of which I got to shoot with for a couple of weeks. According to Canon, the photo quality isn't final yet; while past experience tells me that it probably won't change much, keep in mind as you read and look that it's all subject to change.
With 50-megapixel resolution and anti-aliasing-filter cancellation, you'd expect the 5DS R to be the sharpest Canon yet. Take a look at what a preproduction sample of the camera yielded.
