Very impressive BW. Seems like you get the reach of the RF200-800 at much less cost with the R7. Have you tried this set up with the b1.4 tc, please?
Thanks

I tend not to use the 1.4 converter, especially for flying stuff, but I did for this Osprey last September.
When I'm using the converter it's usually to make close objects bigger, rather than distant objects closer. It spends most of its life in my pocket or, more often, at home. I was photographing waders from the car, in South-west Spain. They were fairly close, but I had the converter on for them, mainly to make a little stint a bit less little. An unexpected osprey came flying close by, so I just had to hammer the shots off with the R7, 100-500 and 1.4X.
The trick for clear photos, as with any kit, is to be as close as you can get. As Brent Hall says in his very useful Youtube videos, 'Physics is not your friend', and all the magnification in the world isn't going to get good detail in a bird that is too far away. Even at this relatively close range, closer than you'd normally see an osprey, with 700mm on a crop body (1120mm), the moisture and dust particles in the air were having a softening effect.
The Caspian Tern, nearby an hour later was taken at closer range without the converter.
I've got a 200-800 since February. It works with the R7 and I'm using it at home, but all that reach on a crop body makes it too hard to track and frame flying birds at a proper range. The R5 is better.
