Second image: I like the symetry of this. Have you tried it with the gull cloned out?

Let's not forget the 1.5x crop factor. The DA* 300mm lens has a film equivalent FOV to a 450mm lens (close enough to 500mm for me).
Add to that a 1.7x T/C and you have a 765mm equivalent lens.
There was a super-telephoto lens planned, it used to be on the roadmap. I haven't looked lately.
If we say a 300mm lens apears to bring a subject 6 times closer and a 500mm lens brings it 10 times closer, how, by selecting a smaller image size (croped) do we change the magnification factor?
FOV is equivalent but not object image size on any sensor for a given distance. I still work on actual lens focal length.
Always an issue topic this one. Nikon have bodies that auto crop for digital only lenses, that does not alter the actual object image on the sensor. True, the object image covers more area of the sensor if cropped size but then you print up to standard sizes and bring in the 1.5x factor.
I'll stop here before I confuse myself and loose the point.
Best regards

Seagulls - otherwise known as "Maritime Shyte Hawks" are vermin and should be treated as such.
Gull, Great Black-backed - Larus marinus
Gull, Lesser Black-backed - Larus fuscus
Gull, Herring - Larus argentatus
are all on what is called a General Licence as as such I try to get as many shots at them as possible.

Last image is very good. Well caught and sharp.
Now had it been a Hawk?

It also covers my electric aircraft and helicopter batteries and my Makita's (converted to LiPo batteries).
