Focus accuracy: D5000 & 85mm, f/1.8. Measuring @ 1 meter the focus is off by 5mm.

The measurement was made at an angle of 45 degrees with a calibrated steel ruler.

Would this be considered within specification?

Isn't the target too close to make the test valid?	Patco	6 months ago
I just tested the focus at 5 feet and it's off by about 1cm. Also a pic of my wife's head	Jerry R	6 months ago
