Sony’s full frame mirrorless A7 series series has gone great guns since the get-go, with photographers ditching their bulky and weighty DSLRs and switching to more streamlined mirrorless cameras in increasing numbers. Sony’s A7 Mark III, which we’re looking at here, could itself be viewed as the junior partner of the A7 lineup, but it’s still a formidable option.

Canon, by contrast, could be accused of being rather slow off the mark. Yes, it’s had its APS-C sensor EOS M system for a few years now, but its heart never really seemed in this mirrorless ‘lark’. That is, until the arrival of its full frame EOS R system in late 2018, since then joined by the EOS RP and EOS Ra, with apparently more to come, including a more ‘professional’ example.
