Canon EOS-1D X Mark III
I purchased the Canon 1Dx Mark III in February 2020. After the exceptional performance of the 1Dx Mark II, upgrading to this camera was an easy decision. The 1Dx Mark III has two more FPS (16), 191 AF points vs 61, 1000+ shots in RAW vs 170 and a new DIGIC 9 vs DIGIC 6 processor. The Mark II is also 32% heavier, so losing weight with the Mark III is a nice advantage. Battery performance is better at 2850 shots vs 1210. The Mark III also has WIFI and smartphone remote control. Some other minor Mark III advantages worth mentioning are illuminated buttons and better LCD resolution (2100k dots vs 1620k dots. The only con is that the Mark III now takes a new style card, Cfexpress. Although this card enables faster write speeds, they are currently very expensive.
