Wow! That's very cool!! Does it work well? I wish I had any sort of DIY skills, I struggle with Sellotape
Yes - it really works quite well. I screw it onto the lens just as you would a normal filter. I have not (yet) added a hinge for the side that opens, right now, it is just a bit of tape, but it should soon have a latch and proper hinge. I may build a new one just to improve the dimensions a bit.
It eliminates totally any spurious light, avoids entirely the need to take care that the filter plate will not fall out (the fit is tight so even if the "door" falls open, the filter does not easily slide out) and stores quite well in a plastic sandwich zip-loc bag
I would like to say I would be happy to make one for anyone that would like one - but I can't make any guarantees. If you would like for me to give it a shot though, I would be happy to put a few on the stack, as it were. I have LOTS of scrap wood I would love to be rid of, and it does not take long to make. If you would like a recess for the lens adapter ring, I would just need to know exactly how deep and what diameter to make it.
Other than that, it is just scrap wood and shipping.
Eschew obfuscation and pompous prolixity.
Gear: Canon 20D, EFS 17-85, EF 70-300, many hopes for more soon.
