So a standard 8x42 binocular has a relatively large 5.25mm (42÷8) exit pupil and an 8x21 compact has a much smaller 2.6mm one (21÷8). This is one of the weaknesses you have to accept when choosing a compact binocular. In poor light, you will not perceive as bright an image as a larger binocular with the same or similar magnification. The fixed focus design, with less moving parts means that there is less chance of something going wrong and therefore only adds to their suitability for these uses.

Ideal Uses: Like most compact binoculars, these are ideal if you are looking for a take anywhere pair of binoculars, perfect for camping and I would take them hiking with me if birdwatching was not my main focus. I also see them sitting in my car, or in my golf or kit bag to be used at any time. They also make pretty good safari binoculars and are ideal for most types of holidays as they can easily fit in with your hand luggage. As with most fixed focus binoculars these don't have a very good minimum focusing distance. The minimum distance that you can focus on an object is at 20 meters (65.6ft) away, which compared to centrally focussed binoculars is poor (I consider anything under 6ft to be very good). So if you are looking for a compact binocular specifically for things like observing butterflies then I do not recommend getting these. Rather take a look at these close focusing binoculars.a b c Miller, David (2001). The Illustrated Directory of 20th Century Guns. London: Salamander Books Ltd. ISBN 9781840652451.

This experience will change from user to user and is dependent on some specific uses where being able to minimize image shake can be extremely important:Binoculars with a powerful magnification are in theory able to deliver greater image detail than those with lower powers. Or to put it another way, you are often able to see more at greater distances with more powerful binoculars. Unlike the artificial tints that you sometimes find on cheaper binoculars, the colour reproduction to my eyes looked and felt natural. Considering that these have such a deep field of view, I was impressed how good the general contrast of the image was. that the binocular can be adjusted to by opening or closing the hinge to enable them to be correctly set up to fit the distance between your eyes.
