Why is there no thread on posting pictures of a specific focal length comparison?

If I'm not mistaken, Tamron has a page where one can 'zoom' through the different focal lengths of one picture to get an idea of the FOV of each focal length.

Maybe you can start one? You can shoot the same subject from 16mm up to 400mm with your lenses and post the images here. In steps of 5mm that will be about 80 images. I think Tamron's approach is a little bit more clever, by the way

Sigma 10-20/3.5@10-12-14-17-20. Pardon the flare, straight into the sun without hood. Should do the trick, though, having the camera still was prioritized over IQ.

Double post for the sake of tidiness:
If anyone really wants, I could do a 10-12-14-17-20-24-35-50-70-90-100-150-180-300 with the lenses available to me. Would take some time, though, and it is in the wide area the most questions about "10 vs. 12/14" arise.

Edit: Not to mention the looks from my neighbours.

Indeed, after all 4mm is 40% difference. Probably empasized by the different objects near and far in the picture, though.

Thanks for those nice example of images egordon..
another good idea is to determine to zoom lenses wide to zoom end
like the sigma 17-70 two images @17 - @70
tamron 28-75, DA12-24, 16-50, etc
