Product Information

that there was a particular optical advantage to using ED glass manufactured by the Schott organization in either the Terra ED's 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 At first glance when viewing the binocular online, the Zeiss Terra ED 8x42 looks quite similar to the more expensive, German made Conquest HD. However, once I took it out of the plastic box it was quite clear this was a cheaper binocular. It feels solid enough and has a good weight to it, although at 690g it is certainly not too heavy. I couldn't help noticing that it just doesn't have the same quality about it that other Zeiss models do have. To be honest, it is completely unfair to expect that same quality given the difference in price. has changed its relationship with binocular users! It is no secret that their focus has been on premium quality

You get an overall detailed and accurate image, and there wasn’t much chromatic aberration. At this price range, we consider the image quality fairly decent. Waterproof and Fog-Proof I found the low light performance of the Terra fantastic. I used them in early evening and they really sparkled. I could easily get a sharp image even past sunset. I would say this is a real strength and fantastic considering the price. The interpupillary distance range of the Terras is shifted towards the high side, ranging from 57.5 – 76 mm. This means that peopleExcellent fast focus feature with focusing achieved through a large wheel that works perfectly whether fingers are bare or gloved. The Terra ED is designed so that your index finger naturally falls on the focus dial. That way you can adjust it with ease or requiring too much movement. That’s pretty smart as every second counts when you’re birdwatching. bit fuzzy on the periphery and we need to swing the binocular to see a well-defined image in its "sweet spot"!

Before we leave the physical construction of the binocular, the build quality of the Terra ED binocular we tested favorably impressed resistance in their focus than these have, but for our tastes, this is just about perfect! We noted that the Terras also have Schott is sometimes referred to as "a sister company in the Carl Zeiss foundation," so it might seem somewhat natural for Zeiss with other binoculars in this price range, and it carries both the Zeiss name, and the support of that respected optics company. We don’t think Zeiss hasEvidently, most companies thought not. Zeiss thought otherwise, and the result was the 42-mm Terra ED binoculars at 8x and 10x. While the diopter adjustment knob is more like a ring than a wheel, it is made from rubber and super comfortable to use. It does exactly what we expect from it, to adjust the diopter of the binoculars. However, I have to say that I find it really difficult to get a sharp image at the close focus end of the spectrum. Maybe it is the fast focusser, but I found it very difficult and two of my much cheaper 8x42 models easily outperformed the Terra in this regard. This was a big disappointment for me as I do a bit of insect watching. Although these binocular are more comfortable to hold for short periods, I’d say they will suit you better if you have a steady hand.
