Canon RF 800mm f11 vs Sigma EF 150-600 (C or Sport) w/ Sigma 1.4 TC (1401)
Has anyone taken a close look at the image quality and usability(focusing etc) of the Canon 800mm f11 vs the Sigma 150-600's with the 1.4 TC? I own the Sigma and am considering the 800 as a lighter native RF option with an EOS R. thanks in advance
