I do about 95% bird photography and the RP is just not cutting it. I was looking to upgrade to R5 but not sure if my sigma 150-600 will work well with it. Anyone have much experience with this combo?
I have the C version and it seems to work well for me. I keep up with the Sigma updates. It works better with my R5 than it did with the 5DIV I had. It's not perfect, but it's an $1100 dollar lens and can be had for less if you watch for sales.
