I’m liking the Canon M50 and purchase it. Will my old T3 and T5 rebel lenses fit the M50? I’ll be taking some travel video, portraits and maybe some sports photos. Pros/Cons?
I am going to upgrade from the canon T3 and T5. What is the next best option after that under $700 that would have wifi or Bluetooth and is compatible with my 75-300mm lens?
