What lens is Canon 6d suitable for? I used to have a18-135 50-1.8. Solution.

6D is a camera in Quan Huafu, which can only use the lens with EF bayonet, but not the lens with EF-S APS-C format. So your old 18~ 135 lens can't be installed on a full-frame camera like 6D, so you can only use a 50F 1.8 camera.

Quan Huafu suggested that EF 24~ 105 F4L should be USM, EF 24-70mm f/2.8L II USM and EF 24-70mm f/4L should be USM, which can be used as common hanging lenses. Other focal lengths such as 16~35 or 70~2 10 can be selected according to your own subject.
