Samyang AF 85mm f/1.4 RF

Canon rf 85/1.2L
Sigma 85/1.4 art
Canon ef 85/1.4L

Tytułowy Samyang rf 85/1.4 wg mnie ostry, ale niektórzy piszą, że jednak nie

Mam też nadzieję, że w końcu Sigma też wejdzie do gry i nowa 85/1.4 DN (pod sony) też wyjdzie dla RF-a. Jednak ART to już kawał kloca. Szczególnie na adapterze.

Canon RF-mount
Canon's RF lens lineup thus far has shown a distinct focus on the needs of professional users, with many of its first lenses belonging to the premium 'L' range.

Canon hasn't opened up its lens mount to other makers, so there's limited third-party support available at the moment. If the RF mount gains anything like the popularity that the EF mount did, it's extremely likely that other companies will find a way to offer autofocus lenses, but widespread third-party support for RF may be some years away.




Diagram covers autofocus primes and high-end zooms in the 14-200mm range. Lineups correct as of September 2020.
Canon currently uses a variety of motors in its RF lenses: primarily using the company's fast, smooth 'Nano USM' technology and the ring-type USM motors that underpin most of its high-end DSLR lenses. These ring-type motors appear to work pretty well with Canon's dual pixel AF system but aren't always the smoothest or fastest, especially given that they tend to be used in the lenses with large, heavy lens elements that need to be moved.

The RF 35mm F1.8, meanwhile, uses a small stepper motor, which makes it noticeably slower and noisier to focus than the best of Canon's other mirrorless lenses.
