1. What are your needs?
The main thing to consider is what your needs are. Is it nature observation whilst out on a day trip, birdwatching, hunting or navigating at sea? Remember that the best binoculars are the ones you actually have with you. In other words, don’t buy a binocular that feel too big and heavy for your purpose. Otherwise, there is a risk that they will be left behind.
2. What binoculars model and size are right for you?
Binoculars models can be divided into three categories depending on their size of front lens diameter: compact, mid-size and full-size binoculars.
Compact binoculars
Objective diameter between 18 and 28 mm. Small, lightweight binoculars to always have with you – in a pocket or hanging from a belt. Compact binoculars are best if you plan to use them for shorter periods of the daytime.
Mid-size binoculars
Objective diameter between 30 and 50 mm, often the perfect balance between brightness, stability and weight. These binoculars are easy to use and fit most uses such as hunting, bird watching and nature walks.
Full-size binoculars
Objective diameter larger than 50 mm. These binoculars provide a stable, detailed and amazingly bright image – perfect when you need to look at something for a long period of time. We also have models with a high level of magnification that allows you to get really close to the object. Large binoculars are of course also heavier and if you want to use them for longer periods, it is a good idea to use them with a tripod. Depending on the size, these binoculars often remain stationary in a boat, car or cabin.
3. What is the right level of magnification?
When you have decided which size of front lens diameter that you want, it is time to consider magnification. A lower magnification means that the binocular become brighter and have a larger field of view, which makes it easier to find and follow the object. What is more, it is easier to keep steady so you can see the image more clearly. If you sit in a boat that is rocking or are out on a brisk walk and are likely to be slightly out of breath whilst using your binoculars, it is a significant advantage to have binoculars with lower magnification power.
With a higher magnification you get closer to an object, which is of course important for bird watching for example. But the narrower field of view makes it harder to locate the object and keep the binoculars steady. A higher magnification also usually means not as good low-light capabilities.
- 6-7x magnification is easy to hold, stable and gives a bright image. It works well for marine and all-purpose use.
- 8-9x magnification works well for all-purpose use, hunting and bird watching.
- 10x magnification is recommended for bird watching or watching from a long distance like in the mountains, for example.
4. What prism construction should you go for?
There are two basic prism constructions used for binoculars:
Porro prisms
Porro prisms are classic models of binoculars recognised by its W-shaped appearance. These models are characterized by a large field of view and a good three-dimensional image. They are less expensive to manufacture, which makes them affordable. However, they are larger and heavier than roof prism binoculars.
Roof prisms
Roof prisms are shaped like a H. They are smaller, lighter and easier to grip than binoculars with porro prisms. Their linear transmission of light gives optimum brightness. This special design is also the reason why roof prism binoculars are typically more expensive than porro prism binoculars. Keep in mind that the more advanced anti-reflective coating you select, the sharper, brighter and more vivid image.
5. Is there a warranty?
Having a warranty or guarantee from the manufacturer makes it much easier for you to get your binoculars replaced if they become damaged. Focus Sport Optics binoculars have a 10-year guarantee. Buying any of the Focus Sport Optics binoculars is a guarantee that you will receive a quality product with the best possible value for the money and extensive warranties.
Take care of your binoculars and use the correct equipment to clean them: e.g. a blower brush, cleaning cloth or special cleaning spray that can be necessary to dissolve grease or dirt. Suitable products are available at well-stocked photo stores and opticians.
The guarantee does not apply where the binoculars have been handled carelessly, such as being dropped from a height greater than standing or subjecting them to rough treatment.
