Has a metal mount. Canon EF-S 18-135mm f/3.5-5.6 IS USM. Canon RF 24-105mm f/4L IS USM. A metal mount is generally superior to a plastic mount as it is more durable. weight. 515g. 700g. We consider a lower weight better because lighter devices are more comfortable to carry.
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
