DIY [#28] ~ Canon EF 400mm f/5.6L USM Lens Solar Filter, now with hood, 08/01

IMG_9963.CR2Why have I added this hood, given this lens has a built in hood? All one has to do is extend that hood and lock it in place.

Well, since I chose to not rely on Thousand Oaks getting me the filter I ordered in time for the eclipse, I made my own.

The sizes I used [O.D. 86mm vs. 77mm] prohibit extending the built-in hood. So, here you are… The¬†hood and lens cap also protect the solar filter film.
