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?
I’m not sure if this is viable or too expensive, but we do like Sigma and use their lenses professionally. This has just been announced: https://camerajabber.com/sigma-launches-100-400mm-f5-6-4-dg-dn-os-c-for-fujifilm-x-mount/
It might be a bit slow at the long end though for birding, but I’m sure it’ll be razor sharp.
