They really change your viewing experience
Binoculars are normally hand held and it is impossible to avoid a certain amount of image shake.
This problem is accentuated when the instrument is used in a a boat or a plane or other moving moving vehicle.
The normal solution when on solid ground is to mount the instrument on a tripod; this works well for astronomical telescopes and in some circumstances for binoculars. However if you are in the back of a moving jeep whilst on safari it is not much of a solution.
One of the most important features of binoculars is that you can take them anywhere, they are great for observing sports events, wildlife as well as distant natural objects such as mountains, planets and stars. It is possible to mount a pair of binoculars on atripod but you have to carry the tripod around with you and it takes time to set it up.
Tripod mounting in a moving vehicle or a boat is not a solution, the movement and vibration will be transmitted to the binoculars and you will get a blurred image and one which is very uncomfortable for your eyes.
The more powerful the magnification the more noticeable will be the problem of shake. This is especially noticeable with astronomic observation, the stereoscopic effect of the binoculars gives a more realistic view than a telescope, but if the image is not sharp the observations will not be satisfactory .
Of all the brands of optical instruments on the market the one which provides the best value for money is Canon. Canon is at the forefront of optical technology and never more so than with image stabilisation technology. The Canon IS Binocular range incorporate image stabilisation and this feature makes an enormous difference in use. The quality is great and the prices are more than competive.
