Meanwhile, Canon has announced the full-frame 5DS (and a variant without an OLPF called the 5DS R). Their big feature is 50.6 megapixel resolution, but not only do they max out at 1080p video, they’ve been stripped of the 5D Mark III’s perfunctory
microphone headphone port and HDMI output.
So, just to be clear, Canon charges you ¼ the cost of a 4K video camera to remove a thin plastic film from the sensor of your 1080p camera that’s all about resolution.
I know there are a few people who need crazy high resolution (and far more who think they do), but I’m not one of them. I’ve been having a blast shooting stills with my 12.2MP full-frame Sony a7S, having picked up a razor-sharp, if rather unsexy, 35mm F2.8 lens for it. Here’s an example—click through to see it at full-res, along with a few more shots.
Thanks to Gordon Lang of Camera Labs for pointing out that DP Review had it wrong about the microphone port being removed—it's actually the headphone port. He also clarified this:
Also the 5DS R adds a low pass cancelling filter, rather than removing the existing OLPF. It's like the D800 and D800e. 3yrs ago!
