The Japanese firm has introduced two new references within its range of RF mount lenses, the Canon RF 50mm f1.8 STM Lens and Canon RF 70-200mm f/4L IS USM . These are two new optics that replicate what are “two of your most prized EF lenses “for the new mount, expanding the family of lenses available for your Canon EOS R full-frame mirrorless models.
The first is a new version of the classic 50mm luminous lens that promises “quality without compromise”, while the other is the conversion to the RF mount of a versatile telephoto lens widely known for its portability. So classic are the EF lenses from which they are based that both have their own nickname: ‘ nifty fifty ‘ in the case of the 50mm, and ‘ Cocito ‘ in the case of the telephoto lens. Therefore, both optics would be the new ‘ nifty fifty ‘ and ‘ Copito ‘ in RF mount.

The new RF version of the Canon EF 50mm f/1.8 STM is, as we say, the classic lens with a standard angle of view that provides a perspective close to that of human vision and with an aperture of ƒ1.8, very useful for all kinds of situations but especially suitable for disciplines such as portraiture, Thus, always according to the brand, ” it is perfect for enthusiast photographers who are switching to the EOS R system. Photographers who want to shoot everything from portraits to landscapes, from day or night, they will be able to achieve incredible image quality.”
In addition, according to Canon, “an entirely new optical system” has been incorporated that is based on six elements in five groups with several PMo (precision molded optics) aspherical RF 50 lens. In addition, it also features Super Spectra coating technology, which creates “a harmonic color balance that reduces flare and ghosting, as well as chromatic aberration “.
On the focus side, it features an STM motor “for flawless AF performance” and its body has been redesigned “for photographers to shoot in comfort “, incorporating a click less lens and focus control ring, ” so photographers can exercise intuitive control over camera and focus settings, while viewing the subject .”
Its minimum focus distance is 30 centimeters (five less than the current EF version), its diaphragm is of the circular type with seven blades (and, of course, it promises “beautiful bokeh”) and its filter diameter is 43 mm. regarding its dimensions, it measures 69.2 x 40.5 cm and weighs 160 grams (very similar numbers to the EF version).

For its part, the telephoto lens also presented today belongs to the L series (the most professional of the house) and is a telephoto lens with a standard focal length but which stands out for its brightness ( ƒ4 at all focal lengths) and, above all, for a compact size and lightweight . In fact, Canon points out that it is “the world’s shortest and lightest f/4 interchangeable lens in its focal range “, offering ” amateur” and professional photographers high performance, flexibility and a compact design to suit different genres, from wildlife to sports, from travel to portraits .”
The truth is that its 695 grams of weight and 11.9 cm in length allow the brand to show off its chest, since they claim to have achieved “an incredible reduction of 32 percent compared to the equivalent EF lens “. On the other hand, it incorporates a reversible lens hood “that fits perfectly in front of the lens, allowing photographers to store it without problems when moving from one photographic setting to another “.
As for the optical system, the lens employs 16 elements in eleven groups and “incorporates additional enhancements such as Air Sphere Coating and four Ultra-Low Dispersion (UD) lenses “to deliver “improved image quality “. Its diaphragm consists of nine blades and, as we have already said, it has a constant f/4 aperture “which provides extraordinary booked […] and incredible detail “.
Also of note is the minimum focusing distance that drops from one meter in the EF version to 60 centimeters. On the other hand, it incorporates Canon’s five-stop optical image stabilizer, which can go up to 7.5 stops combined with the Canon RF 50 and EOS R6. As for the AF, it incorporates a Dual Nano USM motor that promises “incredible continuous focus levels “.
Finally, its body incorporates a shock-resistant fluorine coating ” providing the high durability and robustness of Canon L-series lenses ” including thermal protection coating, ” as well as a dust and water resistant construction, which makes it very practical to use in both extremely hot and cold climates .”
