Our Analysis and Test Results
As a brand with a quality reputation, Zeiss makes quality products. We found the Terra ED 8x32, however, to be darker than expected, when compared to similar products, and also not as comfortable as we would like when held to the face. Yet this pair of binos had the best field of view in our tests.
Performance Comparison
Clarity
The Zeiss Terra ED 8x32 lives up to the Zeiss name when it comes to clarity in a smaller optic. In our clarity test, Zone 9 was seen on the ISO 12233 chart with no noticeable chromatic aberration around the edges. We could see some defocusing around the edges but we generally thought the clarity was good in this smaller-sized lens, even if it was not as clear as some larger higher-end models.
Brightness
When compared to the exceptional models that made it into our test group, the Zeiss Terra ED 8x32 was a little less bright. The Zeiss Terra ED is fully multi-coated, but the 32mm objective lens is smaller than some of the other binoculars with 8x magnification, which impacts the ability to capture and transmit light to the viewer — resulting in less overall brightness.
Comfort
While testing the Zeiss Terra ED 8x32, we found that the interpupillary distance would put pressure on the ridge of some testers' noses. Not all of the testers found it uncomfortable to use, but some did. So if you have a sensitive bridge of your nose, it would be worth trying these out before buying. The eye relief of 16.9mm is in the middle of the test group and should provide adequate strain relief for most users. The Zeiss Terra ED 8x32 also comes with an UnderArmor harness for strapping the binoculars to your chest, which is a nice co-branding touch.
Field of View
The manufacturer-specified field of view is 404 feet at 1000 yards, and after actual testing, the Zeiss Terra ED 8x32 still maintained an above-average field of view, compared to the group of binoculars we tested. At 353 feet, the field of view is on par with many of the 8x magnification optics that we tested, and still 30 feet greater than the average of the entire test group.
Ease of Adjustment
The hinge point for adjusting the interpupillary distance is stiff and hard to move. This helps the binoculars stay in place better, but can also make them difficult to adjust. The focusing knob is smooth and focuses fast and easily. The diopter is located on the right eyepiece and is easy to adjust but has no locking mechanism to keep it from accidentally moving.
Close Focus Range
The Zeiss Terra is able to focus on objects just 5.3 feet away, an impressive close-focus range that only the Swarovski EL 8.5x42 could match. So if you happen to be visiting an aviary, butterfly house, or maybe you are fortunate to stop at a point along the Monarch butterfly migration, these would be an incredibly handy pair of binos to have in hand.
Should You Buy the Zeiss Terra ED 8x32?
These binoculars definitely cover a niche in our testing group. With the 32mm objective lens, they are smaller and lighter in weight than many, making them a great pair to tote along while hiking. If you find them on sale, this is not a bad product. However, our advice would be to try them first since they can be uncomfortable on the face for some users. Decide if they are right for you or if it is worth exploring other sizes that may be heavier, but offer greater overall benefit.
What Other Binoculars Should You Consider?
Although much larger, the more attractively priced Vortex Diamondback HD 8x42 and the Nikon Monarch M5 8x42, both of outperformed the Zeiss Terra ED in our test. If the compact size is a key feature for you, then look closely at the Vortex Diamondback HD 8x28 which might be the model for you.
