Dealextreme Item# 39814
I use it on my ZxD, makes it like a GoPro. Probably too wide angle for a #11
Thanks for that info, very useful. The 39814 appears to come out best in tests, but I was concerned that the mag mount was larger. If it's 12.8 mm and 9.2 mm it will fit the same ring as my 0.67. The fisheye view is a bit extreme, but I think will give an interesting perspective if I can mount it in my paraglider canopy looking downwards.
Ordered this evening!
