Hi,
First I felt the LensAlign was an overpriced gimmick, but after having read Chuck Westfalls's recommendations and having some thought I don't any longer think so. Being able to mount the thing on a tripod is a good thing, especially if you need to calibrate a long telephoto lens. On the other hand, shooting a tripod mounted device with a tripod mounted telephoto lens in a public place may got you arrested as a terrorist suspect. ;-)
One question:
Shouldn't we first calibrate the camera, that is adjust for lens flange to sensor and AF-detector mismatch and first that calibration has been done try to calibrate each lens? The problem is I don't know how tell one problem from the other.
Best regards
Erik
The LensAlign system, just reviewed here, has an angled focus chart (on the right hand side)
In Chuck Westfall's December Tips, he states:
What does this mean for LensAlign? Does LensAlign solve this issue with the "Sighting" step? Having both the parallel plane chart and the angled chart?
