The size of this lens is important since it determines the total amount of light which enters the device. This means, if you have a device with bigger diameter objective lens, it will help you see better images even in low light conditions.

This ensures if you are looking at a bird, which is actually 1000 metres away, it will appear to be located at a distance of 100 metres when you look through the binocular. Usually, it is advisable to opt for a device with a magnification, ranging from 7x to 12x. If you are planning to use an optical device with a magnification rate more than this, it is advisable to use that along with a tripod.
  • Coating and lens quality – The coating of the lens is an important part to look for while buying a binocular as this is what decreases the amount of light that is reflected and also allows maximum possible amount of light to enter the device. At the same time, the quality of the lens ensures that the images you get to see have better contrast and are absolutely aberration free. You should keep it in mind that the best lenses work better in low light conditions since these transmit more amount of light. It should also ensure that the colours of the images are not distorted or washed out.
