Binoculars

Highest Quality (July 2022)
The high end versions of Zeiss, Leica and Swarovski all have razor sharp images with the highest light transmission, and a wide field of view. Swarovski has been known for their very good service and accessories hence the most popular high end brand in many countries. The latest version 8x32 NL Pure is slightly heavier (45g) than the older EL version and has almost as good field of view and close focus as the Zeiss 8x32 Victory SF. Both are great buys!

Upper Midrange
For about 1000 USD you will notice how the light transmission, the focusing knob and overall quality is somewhat less impressive. But after reviewing countless of midrange binos I believe the new Swarovski 8x30 CL takes the top spot beating the Zeiss Conquest HD 8x32 in both handling and most of all weight.

 

Lower Midrange
Binos at about 500-600 USD is usually where I draw the line. Below this mark the binoculars are difficult to compare as there are so many options and they are good to really bad. But the Nikon Monarch 7 stick out as a surprisingly good pair. They also have the 8x30 version, but since lower quality binos loose light transmission, and the additional weight of the 8x42 isn't so much, I would go with 8x42 version.


Pocket-Binocular My Choice!
I chose the Zeiss 8x25 Victory Pocket as my primary binocular. It compared well to my old Leitz Trinovid 8x40. It weighs a puny 290 g, a field of view of 7.5° or 130 m at 1000 m, a bright image, quick and near focus, as well as being fog and water proof. The Leica 8x20 was more difficult to adjust for my eyes and has a more narrow field of view. This Zeiss doesn't feel limiting in any aspect except for a bit narrow depth of field. The best binocular for trekking and travels!

 

Mini-Binocular
If weight and size is the main concern then I would go with the Swarovski CL Curio 7x21. It has fantastic light transmission for such small binos. The Zeiss 8x20 Victory Compact is less bright and the Leica 8x20 has a narrow field of view.


Image Stabilized (IS)
They have been around for a long time. Quality and battery life has increased and they can be nice to have on a seabirding trip. Canon has been a leader in this niche, but the angle of view is still a big drawback for birders. Other manufacturers include: Kite Optics, Fujinon and Nikon

 

Budget Binocular
If cost is of most importance then there are plenty of options areound 100-200 USD. But you must test them out, and try some of the more well known brands. Opticron is just one of many brands. I have not tested this one, but put it up here as one to compare with and what to expect.


Monoculars
I believe monoculars are difficult to use for birding. I have tried out several of them, especially the larger versions from Opticron, but this puny one from Leica has the by far best optics.

Field of view

For a 7 or 8x magnification you should have about 8 degrees angle of view or 140 m at a 1000 m (420 feet at a 1000 yds). You should not go below 6.8 degrees angle of view or 119 m at a 1000 m (357 feet at a 1000 yds)

Weight

If your binos are 650 g (22 Oz) or above considering buying a suspender or harness to avoid neck injury. There are plenty of simple and affordable version such as Suspender to more heavy duty constructions such as Harness Finally try using the bino on a monopod or short stick (Finstick) for relaxing your shoulders. Look for a tripod adapter to enable this.

Checklist when buying

  • Field of view (120-150 m at 1000 m)
  • Close focus of 2-3m
  • Weight below 650g
  • Image brightness and contrast
  • Smooth and quick focus wheel from near to far
  • Armoring/feel and waterproofing
  • Eye relief (15 mm or more is good for most eyeglass wearers)
  • Magnification of 7-10x (subjective)

Reviews

The National Audubon Society 2019 binocular review is a great one seperated into different categories. The Cornell Lab Review 2013 is still valid though there are a few upgrades since then. Not much is changing technology wise, but a new trend is the field flattener lens (Leica, Nikon etc). It is a really nice feature on the high end versions! Another short Huffpost review including a cheap scope.
