Question: Does this fit on a Canon 12x36 image stabilization II binoculars or a Bushnell power view 10x50?
Document: Not too tight or too loose. This is the most well designed and simple scope mount I have seen that allows the use of an Iphone. The HookUpz is sold as a binocular adapter and it also works with Swarovski SLC 8x30 but not with my image stabilized Canon 10x42 L binoculars. If it fits your equipment this would be a good purchase. If there was an easy light weight way to make a clamping system that would be the one improvement.
I purchased this product to attach my IPhone 4S to a full size pair of Bushnell binoculars. I find that the phone works best in a horizontal position rather than a vertical. Seems like the eye hole lines up better. The problem is the weight of the phone pulls it back down to a vertical position, then it brings it out of focus. Also, the phone does not fit well onto the eyepiece of the binocular. It tends to slip. Would probably work better if binoculars were mounted on a tripod.
too big for my binoculars which are big, it was a waste of money plus the view opening is too small
The images (iphone5 + zeiss victory 8x42 binoculars) won't hold a candle to a designated telephoto lens, but they are better than nothing, probably comparable in image quality to a compact camera with a long zoom.
I've used this a bit for taking pictures of birds. This is a really excellent accessory for digi-scoping, but you have to keep your expectations in check. If you want an idea of what kind of images this can deliver, you can take a picture with you phone through your binoculars, it will take you some time to get the image lined up but it can be done. This product will not improve the image quality but it will make it a lot easier to align your phone and your binoculars.
Provides a pretty clear view. Good price for what it is, not crazy sturdy but if you hold on to your phone and binocs you should be good.
Hunting  binoculars ....doesn't fit any of my binoculars waste of money probably would fit a five year olds binoculars! A shame!! !
I love this case! It works perfectly with my iPhone 5s. When I put it on my binoculars I could take great quality videos of deer. I was even able to fit it on my scope which made it even better.
This has had many people asking where we got this and how does it work questions. It take some practice getting your hand steady so that you can keep the image clear, but it is realy a great gadget.
It's kind of ghetto for an iPhone 4/4S... you have to like tape the inside so you can even fit the lens hook-up on it, you can't use the cover if you have a 4/4S. And the lens hook-up does not really stay on the binoculars. It's a lot of work to get it on your iPhone/binoculars. I'd recommend shopping around.
Answer: No I had to modify a cap I made out of a milk gallon
