Recreating a diagram should be straightforward for someone with SVG skills; there are a few available to recreate if you google for "flange focal distance". A diagram could show an internal view of an SLR camera, with the distance between the lens mount and the film plane highlighted. Perhaps something derived from Slr-cross-section.png. grendel|khan 06:50, 26 July 2006 (UTC)
After spending quite a while drawing a piture myself, I did a search in Wikicommons and found this one which is much simpler and clearer than what I had come up with. Yay Wiki! Egmason (talk) 08:35, 3 February 2012 (UTC)
This article might be a good place to point out that some camera bodies (especially CS and C-mount) incorporate a (screw) mechanism for moving the sensor along the optical axis. The movement is typically very small (and usually not calibrated) but allows compensation for any "irregularities" in the lens mounting that would upset the flange focal distance. Usage procedure is 1/ mount the lens, 2/ set focus to infinity, 3/ point the lens at a distant building, then 4/ adjust the "back focus" until you obtain the sharpest possible image of the building. 184.108.40.206 (talk) 18:36, 18 August 2008 (UTC)
Which lenses should be counted for the "number of primes/zooms produced" columns? In production only or including legacy? Manufacturer only or including 3rd party? Should new issues of the same lens (MkII) be counted separate? I have added Samsung NX (also counting 3 samyang primes, but I think there are more), and Pentax K (counting only Pentax lenses, but everything listed in pentaxforums.com, including legacy lenses). --220.127.116.11 (talk) 02:42, 13 March 2012 (UTC)
