Greetings,

I Have a DLC & JMC and use the Canham compendium shade. The compendium works very well, but it’s not small. It’s about 6” square and the metal “hinges” extend beyond the 6” square when folded.

In use, an L-shaped bracket attaches to the front standard with a thumb screw. A ~4” metal rod goes through the L-bracket and is affixed with another thumb screw. The shade attaches to the metal rod via another thumb screw. This arrangement makes it very easy to access the lens and remove it/reattach it. The front has a slot milled to accept 6”???? square/rectangular filters.

The shade is built out of the same material as the Canham bellows, or at least that’s the way it appears and is very well built, durable and very easy to use. I don’t always use it, though I should, but there have been times when it has saved the image. I highly recommend it.

Regards, Pete
