Vortex Diamondback 10×32 vs 10×42 – How do they compare?

Light Gathering and Transmission

In the daytime, the 10×32 is capable of transmitting more than enough light to your eyes which makes it hard to differentiate the view quality between the two models.

However, if it is in low light conditions like in the jungle or when watching sunsets, the 10×42 binoculars are more capable of producing crisper imagery.

The size of the shaft of light that exits through the ocular lenses concerning your eye’s pupil contributes to the image created. This is known as the exit pupil and the 10×32 gives a 3.2mm diameter while the 10×42 offers a 4.2 mm.

Given that your eyes pupil’s in low light is about 7mm in diameter, this means that the 10×42 binoculars can transfer more light compared to the 10×32 binoculars which they produce clearer images without black rings on the edges.

With the 10×42, the light-gathering properties are expectedly higher than the 10×32 because of the 10mm difference in their lens diameter.

A larger exit pupil also makes it more flexible for you to line up your eyes to the light exiting the eyepieces which makes the 10×42 ideal for novice users.


They have a big difference in weight (approx. 153 g) because the 10×42 requires heavier lenses and a longer and wider chassis. These binoculars are both built with magnesium for their chassis and they use Argon gas inside the chamber which prevents any fogging which makes them perfect for viewing in any weather conditions. Waterproofing is provided by the O-ring sealing coupled with the green rubber armor.

A diopter control knob on the right lens of both binoculars will help you set the barrels to fit your specific eye difference and though it does not lock in place, it is secure enough not to be moved accidentally.

They also feature ergonomically designed thumb recesses on the underside of their rubber grip frames although the 10×32 beats the 10×42 by featuring serrated side edges that enhance your grip and minimize shake even better.

They are both built with premium Barium Crown glass or BaK4 prisms and the mirrors are dielectric coated to increase light reflectivity up to 99% which is quite impressive and works great in low light conditions.

While neither of them is fitted with Extra-low Dispersion glass, the quality of their lenses will not produce much chromatic aberration to cause you any inconvenience. However, the images do suffer from some black or blurry edges.

Field of View

The degree of field of view is quite close with the 10×32 measuring 6.5 degrees and the 10×42 achieving 6.6 degrees which is a slight improvement. This wide view makes for enjoyable observation and minimizes the soft edges.

The level of detail and color attained from the center of the image towards the edges is commendable for both diameters and the image contrast is very noticeable and appreciable. You can focus on objects as close as 1.5 m and far as 341 feet with the 10×32 and 2 m close and 345 feet far with the 10×42 binoculars although this may require some delicate tweaking of the knob.

10×32 provides users with just 10mm of eye relief compared to 16mm by the 10×42. This means that spectacled individuals will have a hard time using the 10×32 model.
