5.0 out of 5 stars Excellent, October 17, 2013
Verified Purchase(What's this?)
This review is from: Celestron UpClose G2 10x50 Porro Binocular 71256 (Electronics)
Pros - great clarity, extremely powerful, easy grip and focus

Cons - not moisture resistant, low depth of field and viewing area.

At about 150 ft the field of view is only about 30ft and the depth of field is about 10ft so you are constantly focusing.

Closest view point is about 30ft which I probably should have gotten 8X for the back yard.

I left them outside one evening and they were fogged up with moisture inside that took almost a week to clear up. Suppose to be moisture resistant?

Great clarity. The optics are great and very clear.

"Moisture resistant" binoculars will not prevent fogging up on the inside. Even fully waterproof binoculars will develop internal fog/moisture if they are exposed to temperature and humidity fluctuations similar to what your Celestron's experienced.

The only way to prevent this is with binoculars which have had the air inside purged and replaced with an inert gas like nitrogen or argon, because those gasses do not condense (produce fog).

Moisture or water resistant binoculars are generally safe to use in some light rain for a brief period of time, but that is all.
