I ordered an older EF mount sigma 70-300mm DL for $30. when i get it shipped to me ill do the same test. im a sucker for cheap astro photography. 300mm x 1.5 apsc crop x 2x digital zoom x 4x crop should give me a 3600mm equivenlant. i hope the optics are clear enough to see more details
Quite nice. It appears par focal. Pretty cool.

also it appears parfocal because the aperture was set around f8 to f11, i cant remember exactly
@@codefallacy Cool... did you ever get that Sigma to work?
@@TheCruisinCrew i did but the focal length wasnt much better than the efs lens used in this video. but it was alot cheaper
It would be interesting to compare it with the still image cropped to the same extent.
great idea, i didn't think of that ;(
