I have a perfect condition Lens Align MK II focus calibrator. I used it to calibrate all my Canon lenses with success. It made my 1.4 lenses usable and accurate. The Lens Align is in perfect condition with no problems. It will be shipped flat and takes 2 seconds to set up. More information about it may be found here: https://www.bhphotovideo.com ...s_calibration_system.html
Price: $45 with free shipping. Please PM me with any questions. Thanks!
