Canon Europe has released a list of recommended lenses for use with the EOS 5DS and EOS 5DS R cameras. Essentially they are concerned that some older lenses may be out-resolved by the new camera’s 50.6 Megapixel sensor.
As widely rumored, Canon has announced the EOS 5DS and RDS R SLR cameras. Both feature a new 50.6 megapixel full-frame image sensor and Dual DIGIC 6 Image Processors, with the 5DS R not having a low pass filter. AF is provided by a “61-Point High Density Reticular AF array” including up to 41 cross-type AF points and the EOS Scene recognition system. Native ISO range is 100 to 6400 and HD video is 1080p at up to 30p.
