It is interesting to see the amount of action currently going on in the HDSLR trigger world these days (more on this in a few days). Here is an alternative to the IR remote holder sold by Red Rock Micro. You can get it here.
I havent tested it yet, but as with all IR system, based on my past experiences, it should work reliably except in very bright sunlight conditions. Sells for 35$ or 65$ with the remote.
