Canon STM lenses have very quiet autofocusing making them great for video but are slower at getting focus compared to USM lenses. STM has to do with Stepper Motor technology, and the power comes from the camera body, not from the lens itself. The Canon STM system was developed specifically for filming video. In the latest version of the DPP manual the following lenses are recommended for what I assume are focus breathing reasons: RF35mm F1.8 MACRO IS STM, RF50mm F1.2 L USM, RF28- 70mm F2 L USM, RF24-105mm F4 L IS USM EF16-35mm f/4L IS USM, EF24-70mm f/4L IS USM, EF100mm f/2.8L MACRO IS USM, EF180mm f/3.5L MACRO USM i Think these recommendations Compare Canon RF 24mm f 1.8 Macro IS STM Lens vs Canon RF 24-105mm f 4-7.1 IS STM Lens vs Canon RF 15-30mm f 4.5-6.3 IS STM Lens vs Canon RF 14-35mm f 4 L IS USM Lens Press ‎ ↵ Enter ‎ for Accessibility for blind people who use screen readers Has rounded aperture blades. Canon RF 24-240mm f/4-6.3 IS USM. Sony FE 24-240mm F3.5-6.3 OSS. Similar to the number of aperture blades, rounded blades affect the way the light gets through to the sensor. Rounded blades, often only found on more expensive lenses, improve the appearance of the out-of-focus areas.

Canon RF 85mm f/1.2L USM. Canon RF 85mm f/2 Macro IS STM. It comes with a lens hood so that you don’t have to buy it separately. These are used to block strong light sources, such as the sun, from the lens to prevent glare and lens flare. Lens hood is reversible. Canon RF 85mm f/1.2L USM.
