Choosing Ornithology Binoculars - Bird Watching:

 

One can not practice ornithology without a good pair of binoculars.

These bird binoculars are all the more important if you are an ornithologist who is an active member of an ornithology club and regularly comes out to observe birds in natural environments. But you will not be able to do without binoculars if you are a ballad enthusiast by the sea, in the forest or in the mountains, loving birds to the point of observing them from time to time.

Jumellesmarine.fr offers you models of quality binoculars perfectly adapted to animal observation in general, and birds in particular; In all possible conditions, even the most extreme. European leader in professional marine binoculars for about fifteen years, jumellesmarine.fr now offers its ranges to the general public and presents fifty references for all applications.

Imagine yourself in front of a Hume's Pouillot, bird very rare in France, that it is probably given only to observe once in an ornithologist's life ... and to have around the neck only one Pair of binoculars approximative!

In either case, to choose your bird ornithology binoculars or bird binoculars, it is important to take into account some parameters: the portability of the binoculars, their reactivity, the choice of magnification and the diameter of the objective.

 

- Choose binoculars with maximum portability.

Amateur or professional ornithology, or the simple observation of birds in your garden or during a walk Sunday will make you walk distances sometimes important.

Your ornithology binoculars should be the least disturbing, lightweight and strong. If you must climb a tree, climb slopes or rocks to approach a coastal shore where sandpipers feed, or better observe a Bonelli eagle couple nesting on the Mediterranean coast; You should favor strong and light binoculars.

These bird watching binoculars should be comfortable when taking hold, because during an ornitho outing, you will grab them mechanically and you divest them dozens and dozens of times.

The weight of these binoculars must be well distributed, the possible accessories well suited to your morphology (neck straps, shockproof case, etc ...). With these intense use binoculars, you need to make one, and over time and hours of observation you no longer have to feel them or see them on you.

If you are a birdwatching enthusiast, devoting a lot of time to birdwatching (and other animals), we recommend that you choose "rubber covered" binoculars: Rubber Covered binoculars are fitted with a rubber shockproof and Very practical with wet hands.

And if your privileged environment for birdwatching is maritime, lake or river, privilege the MT Marine Tested binoculars: absolute watertightness in case of morning mist during a sighting of catmarin diving very early in the morning on a lake, in case of 'Spray if you are observing one of the four hundred species of birds observable on the Island of Ushant, or if by mistake your binoculars fall to the water (immersion of at least five minutes at 4.5 meters Depth for the Fujinon MT Marine Tested binoculars).

 

- Choose very reactive binoculars.

During an observation of birds, the ornithologist, even amateur, must be very reactive in front of the bird.

It is not easy to follow a creeper of the woods on the trunk of a tree or a kingfisher in flight on a river bank because the birds' reactions are mostly unpredictable and birds are faster than ibexes in the Alpes or a herd of wild boars in the forest. You have to be very responsive, and your binoculars also.

The higher the magnification of your binoculars, the greater the focus focus can be. In these cases, we recommend that you choose "center focus" binoculars with center wheel.

 

- Choose a suitable magnification of your binoculars.

You will spend hours watching birds: do not confide your eyes to any material.

The greater the magnification of the binoculars, the greater the relative bulk. For ornithological observation of birds we recommend a magnification of x8 or x10.

 

- Choose the appropriate brightness of your binoculars.

Regarding the brightness of the binoculars, and knowing that the observation of the birds is rather a day activity, a twin lens diameter of 30 or 40 mm is sufficient.

The smaller the magnification of binoculars, the larger the diameter, the brighter the binoculars: on binoculars of 7x50, for example, the magnification is x7 and the diameter is 50 mm. The larger the diameter, the more light it enters and the clearer and clearer the vision.

But all the binoculars with a lens diameter of 40 mm for example are not equal in brightness, and the gap is sometimes very important.

The quality of the glasses, their treatment and the parallelism settings of the binoculars are very uneven from one brand to another, and between the Fujinon binoculars and improbable marks ... it will be day and night.

In low priced binoculars, the prisms are undersized, the lenses more coarsely polished ... and the available brightness can only reach 50% when the Fujinon models are close to 100%.

The most important consideration for this famous brightness is the pupil diameter of binoculars. By dividing the diameter of the lens by the magnification, the diameter of the exit pupil is obtained. Binoculars of 7x50 have a 7.14 mm (50: 7) exit pupil, 10x70 binoculars and a 7 mm (70:10) pupil.

The larger the diameter of the pupil, the clearer and clearer the vision. An index of 4 may be sufficient for an ornithology binocular in daytime observation of birds, but if you also observe mammals at dawn and dusk, then prefer an index of 5 or even 6.
