(Canon RF 14-35mm f/4L IS USM) The transmission result from the DxOMark set of metrics. Transmission refers to the amount of light that reaches the sensor through all of the glass elements of a lens, with a lower TStop signifying more light. Finally ready to upgrade form my Fuji system and trying to decide on my first lens(es) for R5/R6. Really struggling deciding between getting an RF 24-105 f/4 + RF 35 f/1.8 for bokeh/portraits, or instead, pony-ing up and getting an RF 24-70 f/2.8 + RF 70-200 f/2.8. I mostly like to do a lot of travel, portraits, landscapes, and cityscapes. 하지만 모든 유저들이 고급 렌즈 군인 l 렌즈군으로만 라인업을 구성하기 원하는 것은 아니고 가볍고 쓸만한 줌렌즈를 원하는 유저들의 니즈에 부응하기 위해 지난 4월 'rf 24-105mm f4 - f7.1 is stm' 이 발매되었습니다. 화려한 스펙을 가진 l 렌즈 라인이 아니어서인지 The Canon RF 85mm f/2 Macro IS STM is a nice small lens, weighing only 500 grams. It measures 3.1 x 3.6 inches and balances very well when fitted on a Canon mirrorless camera. The low weight is Canon RF 85mm F1.2 L USM Lens, Black (Image from Amazon) Canon STM Autofocusing in-Detail. The Stepping Motor is becoming widely used, especially in budget Canon lenses. When looking at STM vs USM, STM has generally been considered the better option for video. This is because it provides smoother focusing that is less jarring than USM. Has a metal mount.

We consider a lower weight better because lighter devices are more comfortable to carry. Canon make various lines of lenses and they all have their place. USM, STM, Standard (DC / Direct Drive). I will be comparing the Canon 50mm f1.8 STM with th In terms of light transmission, the Canon L series lens is obviously a brighter lens and therefore delivers a better score at 1.6TStop. But although the new Canon lens and the Zeiss lens have the same theoretical aperture of f/2.8, the Canon is 1/2EV brighter than the more-expensive Zeiss lens: the Canon measured accurately at 2.8 whereas the Zeiss tested low, losing a half stop and coming in .
