Nikon Travelite V series

The new Nikon Travelite V series

Whereas the Nikon Premier LX-L 10×25 and 8×20 are the top-of-the-range pocket binoculars from Nikon, the new Nikon Travelite V series are considerably cheaper and comes close to being budget binoculars. Most of them sell for less than $200. They are an upgrade for the old Travelite series, which have been very popular among hikers, birders and nature lovers.

The following models are available in the new V series:
1. Nikon 7508 Travelite 8 X 25mm V Binoculars
($179.99)
2. Nikon 7471 Travelite V 9×25 Binocular
($199.99)
3. Nikon 7510 Travelite 10 X 25 mm V Binoculars
Currently unavailable.
4. Nikon Travelite V 10×25 Binocular (model 7472)
$127.74
5. Nikon 7511 Travelite 12 X 25 mm V Binoculars
$263.24

The new Travelite V series incorporate several new features designed to make them more user-friendly while enhancing optical performance. They boast multicoated optics, and high-index BaK4 prisms for true color rendition, maximum sharpness, and enhanced light transmission. They also use aspherical eyepiece lenses that provide a very flat viewing field and offer markedly improved edge-to-edge sharpness over many conventional lenses.
A new, ergonomically contoured, carbon-fiber body makes the Travelite V easy to use for long viewing sessions without physical fatigue. Ruggedness: The body encases a rugged all-metal chassis and is covered with a durable black rubber armor that provides added shock resistance and a positive grip in slippery conditions.
Diopters: These are of the clicking type, which is very convenient.

Differences:
The apertures (objective lens diameter) are all 25 mm, but the magnification differ: 8x, 9x, 10x and 12x.
The increased power has implications for certain technical features:
The field of view (FOV) decreases as the power increases: 98 meters (321 feet) at 1000 meters for the 8x and 9x, but 87 (285 feet) for the 10x and 73 (240 feet) for the 12x.
The exit pupil (in mm) gets smaller as well: 3.1 (8x), 2.8(9x), 2.5(10x) and 2.1(12x). The reason for this is the fact that the apertures stay the same (25mm). The only way to counter this, would have been to increase the objective lens diameter (like Swarovski did: 20 mm for the 8x and 25 for the 10x). In the case of the Travelite, the bigger exit pupil for the 8x will place it in a better position in dim light conditions. This is clearly indicated from the RBI (Relative brightness index): 9.6 for the 8x, 7.8 for the 9x, 6.3 for the 10x and 4.4 for the 12x.
Eye relief: The eye relief gets shorter as well: 14 mm for the 8x, 12.2 for the 9x and 11.1 for both the 10x and 12x.
Weight:  The 8x and 10x weigh 255 (9 ounces) gram, the 10x 250 gram (8.8 ounces) and the 12x 260 gram (9.1 ounces).
Dimensions: 8x: 4.5 x 4.6 x 2.9 inches; 9x: 5.6 x 5.4 x 2.9 inches; 10x: 4.3 x 4.6 x 2.9 inches; 12x: 5.8 x 5.4 x 2.9 inches
Close focus distance: The 8x, 9x and 10x manage as close as 3 meters, but the 12x only 4 meters.
All in all, although the higher magnification has certain drawbacks, they do offer more power. One should also remember that it does get more difficult to handle a more powerful binocular. The 10x is still OK in this regard, but the 12x could be a problem, unless you can hold the instrument perfectly still. On top of this the smaller FOV of the 12x makes finding an object and following moving objects considerably more difficult.
