There were a lot of camera announcements in 2018. Panasonic rebased the Gh5, and announced the full frame S1 and S1R. Canon released the EOS R and announced the EOS RP.
We are expecting Sony to update the a7 III line.
The trend is clear. Mirrorless, full-frame cameras capable of 4K video have become the new standard.
Is full frame needed? Does it solve low light problems of crop sensors, or introduce new issues?
Do I need to upgrade? What do these terms mean?
