When I go to a play or a sporting event sometimes I wish I could see a little better. Are there any decent "pocket" binocs that are easy and light to carry? They probably wouldn't even have to be very strong. I've heard of "opera glasses" but I don't think I've ever seen any.
Just did the same search several months ago. Basic fact of the matter is it is very personal; some people can't look through small binocs for any period of time, others can, so it all depends. The smallest general size, the 8x20 works well enough for me, but there is a great leap in comfort at the 8x30 level, and then... anyway, point is, find some to try out with a return policy, unless you get a screaming deal. I personally have the nikon lx, which is supposed to be right up there with the leica. Hard to find objective reviews from optics snobs, because most of the time they're whining about not having full size ones. (no offense to the optics cognoscenti)
Additionally, though, you should specify a price range. The best ones go for up to $800 (leica), while better OK ones go for $100. I'd consider a compact porro prism (old school design) for cheap. The rule of thumb of roof prism is roughly double the money for the same optical quality of porro prism. Although they are a little bigger than most, the leupold yosemite, at under $100, is considered an optical best buy, and you can get a 6x30 or 8x30. I use my smaller 8x20 binoculars to take with me everywhere. If you're not looking for edc, then you might be able to go slightly larger.
Lastly, the term opera glasses is two fold, one part that is pertinent, the other I don't believe. First, the opera glass part refers to the fact that the action will be taking place closer than most binoculars are set up for. Hence, they usually use a 6x magnification factor, to offer a larger view of the action. Secondly, opera glasses are what you take to the opera, and as such, are dandied up with mother of pearl, brass, and other non-essential materials. Unless money is no object, and I direct you to Swarovski or Leica in that case, then I strongly urge you to eschew the need to for glued on crystals.
