Mike Burnhill, Professional Imaging Technical Support program manager, Canon Europe, said: “The EF system goes back 27 years now and some of these lenses available today were designed back in the days of film. The technical demands of digital cameras on lenses has meant there has been a need to update lenses over a period of time to match newer cameras’ capabilities.”
“The EOS 5DS and EOS 5DS R have the capability to produce a stunning amount of detail and in order to resolve all that fine detail then obviously you need to make sure you are using the best lenses on the market. To get the best out of these cameras you need to put the very best piece of glass in front of the sensor.”
“The optical advantages of these new generation of L series lenses are considerable.”
“They include a higher resolution and the ability to resolve more detail, better edge to edge sharpness and higher contrast thanks to better coatings, and less loss of light caused by internal reflections.”
“While the Digital Lens Optimiser function in Canon’s Digital Photo Professional software will reduce any chromatic aberrations to some extent, we still recommend using the latest lenses for superior results.”
“Everyone has a slightly different perspective on how they view the world but as an example the EF1635mm f/4L IS USM is an ideal general lens and much sharper than the old EF1740mm f/4L USM it replaced, for example. Likewise the EF2470mm f/2.8L II USM is a superb lens for photojournalists.”
“As a general rule, any EF lens introduced after 2010 would be an ideal starting point to fully exploit the detail from the EOS 5DS and EOS 5DS R.”
“We recommend anyone looking to upgrade their lenses to go to their nearest Canon Authorised Dealer where they should be able to see the quality for themselves. With the launch of the 5DS and 5DS R, rather than bundling the camera with a standard zoom we are running a promotion allowing
the customers to select a lens from a selection of recommend lenses to be purchased together with the body at a discount.”
“Canon recommends the following lenses for getting the best from the EOS 5DS and EOS 5DS R”
