Test du Canon RF 70-200 mm f/2,8L IS USM : Une (R)évolution de taille. Le Canon RF 24-70mm f/2.8 L IS USM est ainsi très similaire à son prédécesseur. Il possède un diamètre identique (88,5 mm)… mais s’avère 10% plus lourd. Ceci en fait le transstandard le plus encombrant en face des offres Sony et Nikon.
Attached to the APS-C sensored EOS 7D, the EF300mm f/2.8L IS USM once again puts in a strong performance, scoring a DxOMark score of 17, relative to the EOS 7D’s resolution of 18megapixels. Equally, the Pentax lens scores very well, managing 15 compared to the 16.3megapixels available on the K-5.
