weight , exit pupil and prism type
554386
The bare weight is 12.5 oz. as indicated in the specs. I've weighed them, it's accurate. The exit pupil can be derived for any binocular by dividing the objective diameter by the magnification. In this case 25mm / 8 = 3.12mm. They utilize porro prisms. Or, more accurately, reverse porro prisms.

Not sure about the actual weight, but they are difficult to focus without a tripod. Strongly recommend you get one if you decide to purchase.

My wife owns an 18x50IS and a 10x42LIS. I own a 15x50IS. Never any issues. Have never dropped them. Knock on wood. We use lithium primaries only. The spotting scope gathers dust since we bought the 15 and 18 power binoculars. The 10's are MUCH brighter (4.2 exit pupil) and have a good field of view. The image stabilization is really worth it.

"Weight: 830 grams"from the spec sheet. It's definitively a lot heavier than any other lens that you will most likely use unless you get into the pro lenses.

They are not heavy for the class of optic. I like them, they fit in a rain coat pocket or on a padded strap. If weights an issue try one of the "chest-rigs", they distribute the weight well. It helps me as I had neck surgeries. They a good for the money.

These binoculars hinge in the middle and the IPD ranges from about 55mm minimum to a maximum of 70mm at the widest. I hope this helps.

This chart on the Bolle site is very helpful: http://www.bolle.com/technologies/goggles/

The three numbers are listed in millimeters. The first number is the width of each lens, the second is the width of the bridge (the area between each lens) and the third number is the length of each of the arms. http://www.framesdirect.com/include/information/frame_size_guide.aspx

I can't answer as to pounds and have been unable to find it stated, but I can say that I use one fully extended with an Einstein and a beauty dish with a grid no problem. My other two hold speedlights with 10x36 strip boxes - no problem there either. The concern is the handle and the collar that adjust the angle are plastic. For now it's working great. I've got 3.

What I did was, using a set of metric vernier calipers measure the outside diameter of bothe the Ocular lens (eyepiece) and the objective lens. Then using the Butler creek measurement table, chose the size as close too or slightly smaller than that measurement. I too had issues with finding what I needed and I did have to surf about a bit, but I finally found a table that had all of scope cap sizes and measurements. Hope this helps

I'm not certain as to the exact weight, but I will say that they are fairly lite-weight for their size. Optically these glasses are very good, but I wouldn't call them compact glasses like some others out there, however I've never had any issue with carrying and wearing them comfortably at all. Try Nikons website for perhaps their more accurate weight? Hope this helps.
