Nice. I have a 300mm. It doesn't reach out as far as I'd like.

Could look at teleconverter but keep in mind f stop loss
Right. I have one, I'd rather have a bigger lens, just for that reason.
Thats the bitch with zoom. Light loss and cost. Its not easy
Sometimes its not the lens but the patience, luck and calm for nature. Was going to save an insane photo and one of my favourites but happy to post if curious
