I just ordered one of these inexpensive remotes to use with my NEX-7. http://www.amazon.com/dp/B003MQWN40/ref=pe_385040_30332200_pe_309540_26725410_item_image Curious if there are some tips & tricks others have experienced using an IR remote with the NEX-7 ? For example, the IR receiver is on the front of the NEX-7.....but the majority of the time I see myself using the remote would be shooting wildlife and I'll be sitting next to or behind the setup. I saw one post where it was suggested to cut a reflector out of a piece of aluminum can and mount it so it sticks up in a couple inches in front of the sensor to bounce the IR signal back into the sensor if trying to activate it from behind. That would be easy enough to do but I guess I'm wondering if that's a common understanding..is it truly necessary, etc? Also wondering what other tips there might be available?
