I am looking for a small, lightweight pair of binoculars that are really good in low light - sorry, I can't remember the name of the quality I need to look for that means good low-light capacity.
I've been using a pair of Bushnell 7x35 binoculars that only cost about $40 but are superb in low light and now would like to find a smaller pair that are equally good, preferably not over a couple of hundred dollars.
I have looked on your website but am unable to tell from the descriptions how big the various binoculars are.
Can you give me some advice?
Thanks for your inquiry.
The ability for a pair of binoculars to gather light is directly related to the binocular's size. A binocular with bigger lenses will be able to collect more light, so often times compact binoculars won’t work as well in low light as larger binoculars do. To some extent we can improve a compact binocular’s brightness with higher grade glass that use light more efficiently.
The Opticron Discovery WP PC 8x32 Binocular is a mid-size binocular though it is still very small and lightweight-- probably the most compact 32mm binocular on the market:
It sells for just over $200 but will be much brighter than any other compact binocular, which will usually have a 20-25mm lens rather than a 32mm lens.
Here is a link to a video which helps explain how a binocular’s aperture (lens size) will impact it’s size and brightness: Understanding Binoculars: Aperture
