Canon Lens Dimensions

If you're planning out the arrangement of camera gear in a bag or Pelican case, it's rather important to realize that Canon lies.

Trying to deal with flying and having my camera gear survive, I started collecting a list of lens, body, and accessory dimensions and trying to figure out how to cram them all into the smallest (and ergo cheapest) Pelican case possible. I figured it would be faster to get the official specifications from Canon rather than actually measuring all my stuff in three dimensions.

I was right and simultaneously wrong: Canon's lens dimensions are for "naked" lenses—they don't include the front or rear caps. So if you plan everything out using simply their published dimensions, you're screwed.

The trick: Add an inch to the published length. The 50mm f/1.8 II, for example, is listed at 2.7" diameter and 1.6" long. Measure it with both caps on, and it's actually a little shy of 2.5" long. Tack on an inch, et voila, plenty of room and a little fudge factor.
