Someone has very kindly lent me his old 400 f5.6 lens and I tried it out at the weekend. I’d always wondered about this ‘classic’ old birding lens.
6 species of waders near Yakumo but the 400 wasn’t quite long enough for any decent shots.

But in this hot weather it was a relief not to be carrying one of the big whites.
And this Osprey was close enough at least……………

The “456” – great light lens for BIFs !
It seems so, hope they make an RF version (they won’t though).
