Canon finally opens up RF mount

SIGMA is releasing six APS-C lenses for Canon EOS RF mount, thus widening the choice of glass for Canon’s previously ‘closed’ RF system.

First to hit the market is the Sigma 18-50mm F2.8 DC DN, equivalent to 29-80mm on Canon APS-C bodies and available from July. In autumn, Sigma will release the 10-18mm F2.8 DC DN, followed by four prime lenses, each with a fast F1.4 maximum aperture – the 16mm, 23mm, 30mm and 56mm.
