For most people the difference is huge because it is a  difference between handholdable and non-handholdable lens. Generally lenses that are closer to 3 kg can be used without a tripod and lenses ...

Thank you, I will try to check my lens tomorrow for corners on D500. As I mentioned my Sony 200-600 definitely has some differences but its a zoom

I do not have Nikon FF so I could nor check for the corners, My Sony 200-600mm has some corner differences but i like its sharpness in the center area. I remember i checked Sony 200-600mm against ...

The difference is small. I belive almost all lenses have some differences in corner sharpness.

Thats what you would expect with Tamron G2 at 600mm f6,3. You could sharpen the photos with topaz sharpen or denoise.

dpreview stated "the lens offers a full-frame equivalent focal length range of 229–914mm" not field of view.

but that does really not make any sense. If you shoot full frame and then crop you do not say - i was using 900mm or 2000mm lens equivalent

Why dpreview.com spreads this silly idea of ​​the equivalent of focal lenght? Just because the camera has a cropped sensor does not mean that the lens has a longer focal length.

Its a very sharp lens wide open at 500mm but i suppose many copies may be a bit soft and you have to calibrate it perhaps on your body.

d500 and z7 have almost the same pixel density so just use z7 in fx mode and crop later in pp. You could use z7 in dx mode for some reasons but i think you gain more to use it in fx. In fx you ...

I think you have some misconception about the reach in dx mode, in fact dx gives you zero more reach.

Nice photos. How is 500mm pf focusing with z6? What AF mode did you use? The photos seem slightly out of focus. In second photo focus is at the bottom right corner

Placed 18^th in the challenge.
