Re: Will the Lens adapter degrade the Film Out?

[Todd at Fantastic Plastic] "[aaron zander] "the lens on the camera isn't putting the image at the exact point it was manufactured to put it."

Ummm... not sure what you mean there. In my particular setup the image is most definitely being put at the exact point that the cine lens was manufactured for. "

sorry, heres what i mean.

A lens is made to put an image exactly on a film plane. And by exactly, i mean to the nanometer now-a-days. These devices are SO precisely calibrated to do that, putting anything in there is just throwing off the image, in the same way breathing film would. Not in the sense that your image will be breathing, but the defocusing/soft image effect when your film is say, pushed forward a bit too much, or if you have a CCD in need of back focus calibration. It's not to say it's throwing everything out of whack. It's more like driving a race car, and having some of your steering linkage miss calibrated, so on a straight your wheel is just so ever slightly turned say, left to compensate. Sure the car still drives, but not as precisely as it could be driving. This causes a warp in your DoF Calculations, can create some funky results in cropping with odd lenses like fisheyes, or gigantic telephoto's. Now not every one uses these, but it's something that can happen.


And As far as DOF adapter we were using, I can't even recall, I've used literally a dozen completely different set ups. My friend went through three before he got rid of his HVX for a red.
