Buying Camera Binoculars Washington DC

1. Binocular magnification and aperture size. First off let's examine some features of every binocam you would be getting. The binocular part of the unit is usually compared to other binoculars by their magnification ability, usually a number like "8 x 32". The first number represents the magnification possible and the second number is a measure of the aperture in millimeters. Aperture means "opening" and here it is refering to the size of the objective lens, where light comes in. So, an 8 x 32 binocular has a magnification of 8 times with an objective lens that is 32 mm wide. Now the bigger the aperture, the brighter the image will be but the bigger the aperture, the bigger the binocular. If you want an all purpose set, go for 8 x 32. I find this is the best of both worlds, compact enough and bright enough.
   
   
2. Camera size and pixel density. The camera part of the binocam can also be compared to other cameras by a number. In this case it is in mega-pixels. A digital image is made up of a bunch of square portions or pixels, that when combined form a picture. The more pixels in a single image, the higher the image resolution and 1 million pixels is equal to a mega pixel. Most cameras these days are in the 3 to 5 mp range. These are great for taking and printing images but are usually at least the size of a deck of cards or larger. When it comes to combining a camera with binoculars usually you will find a lower mega pixel count (around 2 mp) due to size constraints. That's not to say you cannot get a quality camera/binocular combo, just that you might have to shell out some dough to do so.
