Specific Feedback and Self-Critique

I am pretty impressed by the sharpness of this lens at this focal length - the D500 is a 1/2 frame and that gives the 600 at 900, adding the 1.4 brings it to 1275

Technical Details

D500, 60-600 Sigma @600mm with 1.4 extender gives it an equivalent 1275mm, f/9, 1/200, ISO 320 -


Impressive! I love to shoot the moon and find this one very nice! Being just short of full gives some lovely crater detail. Sharpness and detail are excellent and I think you did a very nice job of tonal adjustment. Impressive that the lens can take a TC.
