Bought this binoculars hoping Carson had come with an inexpensive solution to provide high quality zoom in binoculars. I was completely dissapointed when I got My Z80. The image was fuzzy and when I used the zoom at its maximum, the image was impossible to focus and really dark. I returned the item to Amazon. brThe Binoculars look great from the exterior, but really do not live up to the expectations.pBeside, I found out that a 20X magnification is a lot, not really that necessary, not to say a 80X.pShould try other less powerful models with better optics.

I purchased this binocular and knew before that when viewing something with small binoculars at very high mag you will get a dimmer image with some shaking if hand held. The unit is well put together and fun to use. Just at high mag you will have a better image in daylight. Highly recommended keeping the above in mind.

While the zoom is great, the main problem is that a lot of light is required to see the image at x40 upto x80. Also, at these zoom levels, you really need a tripod as every little shake does affect the viewing very bad. So while it's great for sports when you are sitting in the nose bleed seats, it's not easy to get the tripod into the stadium.

Nice quality binocs but... With magnification this high the movement is also magnified extremely as well. Anything over the base power requires a tripod which takes away from the portability. A 25mm objective lense with this high of a magnification is like looking through a straw; NO field of view. If you want this much zoom, stick with a spotting scope (still need a tripod).

This is good binocular but donot use for the zoom. Zoom is not good. It is enough powerful with 20x.
