Calibrating lenses

[johnj167]

I want to check the calibration on my 70-200 f/2.8 lens but I'm unsure about what focal length to check it at. Any help would be appreciated.

For fine tuning your lenses I would always fine tune at the longest focal length.

I fine-tune the length I use most.

I tested at three focal lengths. Fortunately all three tests gave very similar results so I took the average.

I found this system to work better for me than trying to use an angled chart.

i tried several methods and got OK results but finally went with a computer based system Reikan FoCal Automatic Lens Calibration Software - Fully Automatic Lens Calibration and Camera ToolsReikan FoCal Automatic Lens Calibration Software
I got fantastic results using it. I have tuned 3 different camera and many lenses so far. a D7000, D7100 and a friends D7200

I agree with Don, FoCal works really well.
