I’d love to see what you could’ve done with a 400mm. That last one might be much better to emphasise on the bird on the left. It’s much more interesting than including the bird on the right.
There’s a cool thing going on with the main subject and the second bird in the 2nd shot.
Yes 400mm but 4,5 is to dark for Ireland , and prices of f4 and 2,8 this is crazy.
In few months i will try go for old 500mm f 4,5 but hard to find and canon don’t have parts for this lens.
