Exit Pupil is a feature of binoculars that relates to your age and the time of day that binoculars are to be used. One should first understand that the pupils of our eyes change with the conditions of the day and our physical age. During the bright daytime hours our pupil may be reduced to as small as 2.0 mm. However, they begin to expand as the day looses light and may expand to between 5.0 mm and 8.0 mm as darkness sets in.
How about the size of your binoculars? Many companies now offer their lines of binoculars in three categories, compact, mid-size, and full-size. When archery hunting a big pair of binoculars can get in the way during crucial moments while trying to get a shot. However, most compact series binoculars lack the light gathering capabilities that mid-size and full-size models have. Many turkey hunters like to use compact binoculars that can easily fit in a shirt pocket when not in use. Having a good set of compact best binoculars for hunting can be a great asset when you don’t need to see more than 100 yards or so. However in open areas or in low light situations, they can hinder your ability to judge an animal at a distance. Choosing the right size range is the next step in narrowing down which pair is right for you.
1) Power. It’s always a temptation to go out and buy the most powerful binoculars for birding that you can find. Don’t! Experienced birders generally use binoculars that are 7, 8, 9, or 10 power. Less than this and they don’t really do much good. Binoculars over ten power have two problems. First, they are hard to hold still. Higher magnification means more jiggle. Second, the field of view for high powered binoculars is too narrow. This makes it hard to find the bird, especially in flight.
Some manufacturers such as Steiner and Burris make high quality Porro-Prism Binoculars. They sit in a completely different price point $1000USD. They are usually Marine Binoculars or Hunting binoculars and are designed to be tough and waterproof. Steiner claims that the only way to manufacturer an extremely tough binoculars is with the Porro Prism Design as the shape allows for more durability.
I found prices ranging from $1 to $1,000 for binoculars on the Internet; but remember that you get what you pay for, at least up to maybe $200-$400. I think you could get a nice pair for around $35- $75. Check Wal-Mart and Radio Shack.
What else do the Steiner Predator binoculars offer? Automatic focusing comes standard with the 8×30 and 12×40 Predator Pro models. Although the Predator Pro line is a slight step down from the Xtreme, the Pro’s can still provide a great performance.
This might seem trivial at the first thought. But, it’s got clear influence on the degree of clarity of your view. The binoculars’ exit pupil actually is an amplified view of whatever image you’re seeing in the binoculars eye-piece. For getting the finest image from bird binoculars, you’ll need a quality exit pupil, which is not below 4mm.
