hey guys

i was wondering if any of the canon mirrorless cameras are good for plane photography i saw the m5 or the m50 or any for that matter?

i saw a video of a guy taking pictures with the m5 and it looked good apart from the af it was having trouble focusing on go-karts going 30-40 mph and these planes would be going over 100

so if anybody has a mirrorless camera does the af work well with it? or should i wait a couple years before making a purchase.

thanks in advance
