I bought a EOS 5D back in the days with a EF24-105mm f/4L IS USM lens. The camera died recently so I bought a used EOS 5D Mark III. After shooting a few shots, the camera wont work with the EF24-105. The camera works fine with my old EF70-200mm f/4L USM but not my EOS 6D Mark II EF 24-105mm f/4L IS II USM Kit . Review. Product Highlights.

The Panning scene mode reduces subject blurring and blurs the background when the lens is mounted to the EOS M5/EOS M6. The EF-EOS M Mount Adapter is required to use this lens with the EOS M5 and EOS M6. mrM6N.
