#77. "RE: Testing of D800 with Reikan's FoCal application" In response to In response to 76
Target EV was 7.2. I read some of the manual now where Rich notes a few important things. First the AFMA will change with your target distance and it's best to be far from you lens' minimum focusing distance. Second, he recommends you test at your general shooting distance as the ideal AFMA value may vary with target distance even far from the minimum focus distance. So I need to set up my target a lot further away than 1.4m. Finally, zoom lenses are best tested at their longest focal length since this is where DOF is smallest and focusing variations most notable. We just need Nikon to follow suit with Canon and make AFMA values for both ends of a zoom lens and maybe even tie in subject distance to have a range of values for varying target distances. Now that would be sweet.
