Canon have kept a tight reign on lenses for their RF mount cameras. But now Sigma have announced they are about to start making RF mount optics. The first is to be the 18-50mm F2.8 for crop sensor coverage. Here are some details.

Best wishes and good photography.

SIGMA launches interchangeable lenses for the Canon RF Mount system…

SIGMA CEO Kazuto Yamaki is pleased to announce the upcoming launch of SIGMA lenses for the Canon RF Mount system. This will allow photographers to use high-performance SIGMA optics natively on a Canon mirrorless camera. The first six lenses to be announced are designed for crop-sensor cameras.

A high-performance standard zoom for crop cameras

Small but perfectly formed, the 18-50mm F2.8 is the ultimate portable standard zoom for crop-sensor mirrorless cameras. With an equivalent focal length of 27-75mm on an APS-C camera the lens is well-suited to a wide range of photo and video applications, including landscape, portrait, street and architectural photography. It can also be used for macro-style photography owing to its impressive maximum magnification ratio of 1:2.8. 

A constant F2.8 aperture makes it easy to achieve blurry backgrounds, which is ideal for shooting attractive portraits and close-ups. Autofocus is exceptionally fast and quiet thanks to the lens’ stepping motor, which can be particularly useful for shooting video or for capturing fast-moving subjects.

Weighing less than 300g, the 18-50mm is easily portable enough to be carried around for casual day-to-day shooting, but thanks to its outstanding optics, fast AF and wide aperture, it is more than capable of delivering professional-quality results.

End.
