Competition news: Canon RF only “partially” opened their RF mount to Sigma and Tamron

Canon did a Canon thing and managed to disappoint even when sharing what should be good news! Why do I think that?

Today Sigma and Tamron announced the launch of their first RF autofocus lenses, but they are all APS-C. There is a strong suspicion that Canon has allowed competition only in the APS-C segment, focusing on the profitable and much more attractive Full Frame lens line.

This means that large lenses such as the Sigma 50mm f/1.2 FE or the Tamron 35-150mm f/2.0-2.8 FE will NOT be available to Canon R. This gives a competitive advantage to Sony, Nikon and the L-mount system.
