Beautiful work, especially the toucan

Petr, I’m curious to know what you think about the utility of the 1.25x TC in the field. Does the small change in angle of view give you much more than simply cropping in post processing?

eg say you’re at 400mm F4.5 and you want to close in a little more on your subject to say 450mm AoV. Will you just crop it in post or will you flip in the 1.25x putting you at 500mm and then wind the zoom back for 450mm.
