Canon has added to its EOS 5D range with the launch of two 50MP cameras, the 5DS and the 5DS R. Both cameras offer high resolution full frame shooting, primarily aimed at stills photographers. The only difference between the models is that the 'S' has an optical low-pass filter, while the 'S R' has a self-cancelling filter (AKA the R produces a sharper image.)
The two cameras will exist alongside the EOD 5D Mark III, acting as dedicated high resolution cameras primarily intended for studio, landscape, and wedding shoots, rather than the all-round capability offered by the existing model. The Mark III still trumps the S and S R in terms of maximum ISO, and continuous shooting speed, which for me is the only real downside of the 5Dsr. I enjoy shooting astro-photography and the 5Dsr has the same ISO range of the 5D Mark ii. There is no such thing as the perfect camera for every occasion and with the amazing amounts of detail that the 5Dsr captures, I couldn't be happier.
Here are the images from the first week of owning it. Luckily, I managed to get it just before a visit to San Francisco and Sweden.
