I couldn't find a lens case for my traveling to and from shoots of indoor and ASA so I'm going to try to see if this is going to work out. I got tried of taking that dot off for indoor and using the up pin for 3D, so now I just change out the lens. Duck canvas with 2 pieces of vinyl between four pieces of soft baby cotton fabric than the same different color fabric for the sock. Than just tuck it away for travel. Lens is 1 3/8 round.
