I have a Fujifilm camera and decent lens that can do 600mm FF equiv is not cheap. I’m wondering what is the best option for bird photography at that range? There are some tiny 1/2.3 compact cameras like the Sony hx99 that doesn’t seem too good. There also seem to be an option of picking up a m43 camera with a 300mm (600mm equivalent) lens. What is everyone’s favorite options?
The current generation flagships and top prosumer mirrorless have action AF probably close enough to on par vs the previous flagship DSLRs. However, anything below that level may still be pretty slow for fast action.
