As binoculars grow larger to increase the brightness of the image, they also get heavier. This is due to the usual method of making the aperture ( which controls how much light enters the binoculars) at least 5 times larger than the magnification. Due to its reduced size, the aperture in your compact binoculars will be smaller and will collect less light. Which means the image will not be as bright. Therefore, the view with compact binoculars is not going to be as robust as the view with binoculars of normal size. This is why you will need to focus on binoculars which have higher quality components (lens coatings would be one example). When the compact binocular is used during the day, in sunny conditions, you may not even miss the larger binoculars (with their brighter images).

Many manufacturers have compact version of their full-sized cousins. They can typically be purchased for less than the full-sized price. Which makes compact binoculars an economical, as well as practical way to enjoy nature, without weighing you down.So drop the mini binoculars in your purse or backpack and take them along when you venture outside. Even if it is just for a car ride. You never know when you'll need to get up close to something.
