The Meopta Meopix iScoping iPhone Adapter
(Yes, that is really what it's called!)
The MeoPix iScoping adapter is a revolutionary new tool for anyone wanting to capture long-range images and videos. The iScoping adapter slips over the spotting scope or binocular eyepiece - cradling your iPhone 4/4s in perfect alignment to the optic - allowing your iPhone to capture amazing long distance images. You can then use your iPhone for identifying, cataloging and uploading to email or the web the high resolution photos you've just taken. Constructed of injecting molded polycarbonate the MeoPix weighs only a few ounces yet can take the abuse of the hunt. Why drag a large bulky camera into the field? Your iPhone is ready and waiting.
Basically, you put this little iphone case over the eye socket of your binoculars to help it take a picture through the binocs. Genius! And I'm not joking, I have a lot of friends who send me pictures taken through their binoculars, just like the one below I received last week!
I can't seem to find any pictures of deer taken with this little device, so it is up to you to see if it works or not. And you can get it at the bargain price of $59.99!
