Here's my breakdown, for all pictures taken underwater, and those I considered favorites:

Canon 18-55mm 3%, 1% (kit lens came with camera, quickly replaced with Sigma 17-70)
Canon 100mm 56%, 64%
Canon 10-22mm 5%, 4% (stolen last year, replaced with Tokina 10-17)
Sigma 17-70mm 36%, 30%
Tokina 10-17mm 1%, 2% (recent replacement for Canon 10-22)

Yes, the RVR Rain Repellent is made for acrylic.

Mark,

Aren't the smaller aircraft canopies and windshileds acrilyc? Does this work on acrilyc dome ports?

Thanks, Dave

I use RVR Rain Repellent, a product made for small aircraft windshields. I got it from http://sportys.com/P...p/product/12019

... you can't pull the camera backwards through the housing with a zoom gear ...

This depends on the gear. With some zoom gears, the gear grooves run the entire width of the gear. With others, part of the gear is smooth and only part of it is grooved:


With the above zoom gear on a lens, you can't insert or remove the camera without removing the lens first. If the grooves run all the way across the gear, you can.

The lens that used to annoy me with this was my Sigma 17-70mm. That lens was stolen recently with the zoom gear attached. On replacing it, I have gotten a different zoom gear without this problem. I mail ordered the gear from B&H Photo and the accidentally sent the wrong one. But I noticed that the gear I received would work with the lens if I sanded out the inside a little bit, and this one has grooves all the way across the outside. Problem solved.
