I'm liking this new format ... some lensalign images ...

Here are two tests from this weekend.  Above is the 70-200 @ 70mm, no AF tuning, on the repaired D800.  Below is the same lens @ 200mm, no AF tuning.  Both test set ups used the distances recommended by lensalign. Camera and targets were perfectly aligned, per lensalign instructions.

Here is the same lens, from the pre-D800 repair, at 200mm, AF tune at +20
