Isn't Peter's rig similar to Rick Oleson's? I thought to use the collimator, you would need a known-good lens on the collimator body for it to work correctly. I didn't see that detail in Peter's article. As for the whys, I read a mindbendingly detailed article on that once years back in a cinematographer's reference guide and I've forgotten most of it, but they're very fussy about focus accuracy of their lenses (especially zooms, IIRC). If you're looking for details on lens collimation, that may be a possible source. Of course, those were done off-camera so the details of how it was done differed. |
