Best binoculars to buy in india
Have you started observing birds? Do you enjoy bird watching?
First thing that you need is a good binoculars. I started my journey through Bird watching and I didn’t have binoculars (rather I couldn’t afford it). I saved up and bought a binoculars before buying a long tele lens for wildlife photography. To understand better about birds, it is imperative to invest in a good binoculars which will last for a long time. There are enough binoculars to suit your budget and need. I will try to list the key things you need to watch for when you plan to invest in a binocular.
Key features to look for when you buy a binocular - top 4 features
1. Magnification
Magnification is the number of times an object is magnified through the binocular. In general, it is denoted by a number. For eg: 8×42 or 10×42 or 7×42.
The first number you read is the magnification. So an optic with 8×42 means it has 8x magnification.
TIP: Don’t go beyond 10x. If you need more than 10x magnification, it is better to invest in a spotting scope with a sturdy tripod.
2. OLD: Objective Lens diameter.
The second number you see in 10×42 denotes the diameter of the front lens in the binocular. for eg:If the number reads 10×42. That means magnification is 10 and the diameter of the front lens is 42mm.
The bigger the diameter the bigger the lens is. It allows more light and hence you will be able to see better colours of the subject.
TIP: Choose a diameter between 30mm to 42mm. The bigger the diameter it gets, it becomes heavier.
3. Field of View
Quick facts:
- Field of view is not related to Objective lens diameter
- Some manufacturer will give angle of view instead of field of view – both are same.
- Field of view will vary with same magnification. for eg: 10x binocular might have different field of view depending on the binocular.
- Field of view will decrease as magnification increases.
Field of view (FOV) is generally measured in yards (1000 yards). FOV is nothing but the visible area seen through your binoculars.
4. Porro vs Roof prism
Different prism styles are available when you choose the binoculars.
Porro:
Light enters into the binoculars and travels zig-zag to reach your eye. They look bulky and cheaper.
Roof:
Most of the new binoculars are now come with Roof prism. The light enters and reaches the eye through the binocular barrel.
