With the newly introduced RF 50mm F1.8 STM fixed focal length and the RF 70-200mm F4L IS USM Zoom, Canon continues to expand its lens portfolio for its mirrorless R system. Compared to its EF counterpart, Canon is talking about a 32% reduction in size with the new RF 70-200mm F4L IS USM. The weight is 695 grams with a length of approximately 11.9 cm. This makes the RF 70-200mm F4L IS USM the lightest and shortest lens in its class worldwide.
The RF 70-200mm F4L IS USM offers a 5-stage optical image stabiliser, has an ASC coating (Air Sphere Coating) and four UD lenses (Ultra-low Dispersion). The close-up limit has been reduced from 1 m to 0.6 m compared to its predecessor. The aperture consists of 9 blades and, like all L-series lenses, it is equipped with appropriate dust and splash protection. The filter diameter is 77mm.
The new Canon RF 50mm F1.8 STM is also quite compact with its dimensions of 69.2x 40.5mm and a weight of 160g. Compared to its EF counterpart, it is approx. 1mm longer with the same weight and a smaller filter diameter of 43mm (EF=49mm). The minimum focusing distance was reduced from 0.35 to 0.30 m.
The focusing unit of the RF 50mm F1.8 is still driven by a Stepping Motor (STM) which promises particularly quiet and constant focusing, especially for video users.
Both lenses will be available from December for the following EIAs:
Canon RF 50mm F1.8 STM: 225,- Euro
Canon RF 70-200mm F4L IS USM: 1.755,- Euro
