[QUOTE="J-see, post: 388949, member: 31330"] I redid that last one since it doesn't look right. I set up again, used a high enough shutter and went all the way to 1:1 to rule out any difference. I focused with the liveview. This evidently is comparing the ridiculously small. [ATTACH=CONFIG]128040._xfImport[/ATTACH] [ATTACH=CONFIG]128041._xfImport[/ATTACH] This one the D3300 does better.
