The new Canon EOS 5DS DSLR offers the first full-frame sensor camera with image resolution higher than 50MP. The camera is the successor of the Canon EOS 5D Mark III, which uses a 22MP sensor and was introduced in 2012.

It's not long since conventional photographer wisdom stated that no-one needed more than 12 megapixels. However, after Nikon reignited the megapixel race with the D800 , and with 250-megapixel cameras on the horizon, pixels (along with sensor size) are once again where it's at.

With a huge pixel count – find out how Canon's new 50-megapixel DSLRs shape up in our Canon EOS 5DS / 5DS R review. Canon made headlines earlier this year when it introduced two new 50 million pixel SLR models to its line-up, smashing the previous highest resolution model (the 36 million pixel Nikon...

The image quality of the 5Ds is amazing but it did not came as a surprise. With 50.6 MP on a full frame the pixel density is very similar (actually a little lower) compared to APS-C cameras like the 70D.

The new Canon EOS 5DS and 5DS R both feature the same body as the EOS 5D Mark III, but with a drastically higher resolution 50-megapixel full-frame sensor. The cameras are both capable of shooting at 5fps.

50.6 megapixel full-frame sensor; 5fps continuous shooting; Rapid focus and shutter response; High quality 3.2inch screen; AWB with white priority gives good results; Mirror Vibration Control System; USB3 - useful for transferring large files; Customisable picture style options for better results,...

The Canon EOS 5Ds is a 35mm full-frame digital SLR camera with a 50.6 megapixel sensor, the highest number of megapixels ever seen in a full frame sensor. Key features include a 61-point auto focus system with 41 cross-type points, 150k pixel RGB+IR metering sensor with innovative flicker detection...

I've been using a 5DSR for a few months now and I honestly love it. There are downsides. It's insanely expensive. The closeness of the pixels in the sensor mean that it sometimes can't capture movement, such as hair on a portrait subject in a breeze, whereas a 5D mark iii wouldn't struggle at all to...

Nice solid built camera. The 50MP sensor lets you do a lot of cropping and still have great results. Battery doesn't last as long as it did in my 6D and the ISO range is not as good as my 6D either. However the big file size is what I really wanted - the other issues I can deal with.

‘That's more megapixels than most photographers will ever need,' we thought when those cameras first launched. ‘Surely this longstanding war of technological willy waving is over?'

For a long time in photography circles, there were two rival camps – those who swore by the versatility of the DSLR and image purists who lay their allegiance to the superior quality delivered by medium format cameras. The Canon EOS 5Ds could well be considered the bridge between the two.

Superb image quality; Excellent build; Familiar controls and layout
