A fine binocular for the price - 05/10/2016

by Stefanie A. from San Francisco, CA

After trying out a friend's Zeiss Terra ED 8X32s & finding that they actually fit my close set eyes, I decided to give the 8X42s a try. They're a fine binocular for a fairly reasonable price--the image is clear, colors are bright and focusing is fairly quick. They fit my smallish hands. My only real problem is that they weigh more than I really want to carry around. However, given the many pluses, especially the clarity of the image, I'm going to give them a try and expect I'll enjoy having them.

Zeiss - 05/08/2016

by Patricia H. from New Jersey

This is our second purchase of low cost Zeiss optics. We are enjoying both and our second set came as quickly as the first. They were in perfect condition

Ready to bird. No more switching back and forth. We each have our own.

New Zeiss Terra Binocs and Eagle Optics terrific! - 05/06/2016

by Michael L. from Temple City, CA

I bought the Zeiss Terra's as a birthday present for my wife and as her first really good binoculars. They are crisp and sharp and she's commenting on how bright the birds' colors are now. They are Zeiss quality at a mid-level price. They were delivered right on schedule and we've had another great experience using Eagle Optics!

Zeiss Terra binoculars are just right for me - 05/05/2016

by Linda M. from Idaho Falls Idaho

I am very pleased with these new binoculars...capture plenty of light, sharp images, and so much lighter than my many-year-old pair....and they met my budget. Thanks to Eagle Optics...and to the friend who recommended you!

Sharp, clear images of birds - 03/10/2016

by Ed from Boerne, Texas

I was impressed with these binoculars. I have some other 7x42s that cost just a little less than these Zeiss Terra. I'm glad I paid the extra $50 for these. The binoculars are a little more compact and lighter than my other pair. The images are really sharp and crisp. I can focus very sharply with the focus wheel. The binocs were delivered when promised. I've read previous reviews that complained about the loose fitting lens caps. That's definitely one mark on the negative side for these binoculars. It's the only negative I can come up with though. I even like the box the binoculars came in. There is a magnet embedded on on of the flaps so the box closes easily and tightly. I've never seen a box like this before. Very nice.

Just. Wow. - 12/29/2015

by Ben from Dallas

Our first pair of birding binoculars. The images are vibrant and crystal clear. The binoculars are beautiful to look at, as well. 10/10 would recommend.

Zeiss Terra ED 8x42 Binocular - 12/09/2015

by Andrew C. from San Diego, Ca

These are excellent binoculars for the price. The clarity is superb and I like how quickly you can focus. You can focus in on close objects as well as distant. I bought them primarily for bird watching and so far have been very pleased with them. I bought a second pair for my wife as she liked mine so much. I would recommend these binoculars to anyone. Eagle Optics had the best price of all those I checked and matched Amazon.

Perfection - 09/15/2015

by Ricky s. from The net

I recently purchased the 8+42 ziess terra Ed from gander mountain then I received email from eagle optics so I checked there prices and they beat gander mountain by half and I received carrying case neck strap and covers for both ends none of which came with the same pair for twice the money from gander mountain I will be buying my optics from eagle optics from here on and my delivery was very quick

Terra ED vs Atlas Radian - 09/09/2015

by James L. from Baltimore Md.

I ordered both the Atlas Radian and the Zeiss Terra ED to decide which I wanted. Although the Terra was more than twice as expensive I wanted to take advantage of the sale. The Terra had a noticeably wider viewing field and a slightly wider sweet spot. There was no noticeable difference in the center resolution and the rate of fall off in resolution from the sweet spot was not noticeably different in one compared to the other. I did not notice any Chromatic Aberration in either. The contrast in both seemed about the same as well, very good in both. Both seemed solidly made but the Atlas had the better warranty. I decided to keep the Atlas and return the Terra.

Fantastic views! - 08/25/2015

by Jim from Delaware, USA

I have been using the Terra ED for a month now and absolutely love them! Colors pop and details are clear. I am also a big fan of the focus wheel, which is well positioned and large. The sensitivity of the focus wheel took a few days to get used to, but once I did, I have really enjoyed the quickness of finding the proper focus. The one improvement I would suggest to Zeiss would be to provide lens caps that hold onto the body more firmly. The supplied objective covers pop out with the slightest movements.

terrific product - 07/06/2015

by sass h. from kalamazoo

So in love with my Zeiss Terra ED binoculars. Sharp clear image, comfortable neck strap, compact case.
A whole new level of seeing!
Would recommend this product at a great price, especially with the $50 Zeiss rebate.

Zeiss Terra ED 8X42 bincoular - 06/11/2015

by Owl from CA

These were very nice binocular.
They just were not right for me. I could not get them adjusted to make the birds really stand out.
It is a personal choice but I like binoculars with a firmer focus.
I think most people would be happy with these binoculars and would recommend them to others.

A Good Value - 04/03/2015

by Bruce M. from United States

I am very pleased with my new Zeiss Terra ED 8x42 binoculars. I graduated from a pair of Nikon Monarch 3 binos, which I was never completely satisfied with. By comparison these Zeiss binoculars have incredible clarity of vision throughout the field. Ergonomically, they are a bit heavier than my Nikons, but the focus wheel functions smoothly and my grip on the instrument is solid. In my professional life as a pathologist I used many Zeiss products and they were invariably of the highest quality, though often more expensive than competitors. These binoculars seem to be of very good quality as expected, at a very reasonable price.

Great! - 03/03/2015

by Juan R. from Argentina

I'm not an expert but the binoculars are great to me, even in low light condition. It's great the they add a case, but it should be a little bigger, because if you extend the ocular to use the binoculars without glasses the fit super tight on it, the same if you have to bend the binocular to adjust it to your between eyes distance.
To make it clear I'm not complaining, the case is nice build, and is a great add from Eagle Optics, but since they take the time and money to make it it would be a great improvement if they make it a little bigger.

excellent and affordable - 01/30/2015

by Luanne J. from United States

I used my pair of Zeiss Terra ED 8x42 binoculars all day during our Christmas Bird Count. The focus is responsive; neither too stiff nor too free, and they were weatherproof in cold and wet weather. They provided excellent clarity and true colors. I would definitely buy another pair! The only down side is that the right diopter doesn't have a lock position after adjustment.

Completely Happy. - 01/23/2015

by Scott L. from United States

After reading many reviews and comparing the costs and benefits of buying more expensive binoculars I decided on the Zeiss Terra ED 8x42 from Eagle Optics.The binoculars fit and finish are excellent. The rain-guard fits snugly as do the objective lens covers. The binoculars are comfortable in my hands and adjust readily. The focus wheel turns easily and quickly. I really like that. It even works well when wearing gloves. The optical quality is excellent. They are bright and clear with good contrast. Customer service was excellent, and delivery was quick as promised. I'm completely happy with my Zeiss Terra ED 8x42.

Nice equipment for the money-sharp clear

Amazing bins - 12/23/2014

by L.T.J. from Elkhorn, California

I purchased these binoculars to have a backup pair in my coastal office, and was impressed by their clarity and brightness. I field tested them against my regular $2,000 binoculars and two pair of quality, $300 binoculars, and found the Zeiss Terra's to easily outperform the two mid-priced pairs, and be close to my top of the line pair. Subsequently, I set up a test among my co-workers (non-birders), using a standard optics testing pattern and four criteria; sharpness in center of view; brightness; sharpness at edge of field; and 4) comfort of use. The Zeiss Terra's ended up tied with my $2,000 pair, and were top ranked in brightness!! For the price, these bins are an incredible value.

Had to have my own Pair - 12/09/2014

by Roger C. from Detroit, Mi.

In September of 2013 I purchased a pair of these and was very impressed with the brightness of the optics, the close focusing and the ease of turning the focus knob, the feel of the binoculars and everything about them (although I probably could have lived without the plastic display case that they came in). This spring I was out birding with my wife and she asked if so could look through them and I guess she was just as impressed as I was because although she never said anything she also never gave them back. We both own more expensive binoculars but the Zeiss Terra ED's are #1 for both of us. I would highly recommend them.

Zeiss 8X42 - 10/11/2014

by Brent from Pensacola

Chinese made Zeiss. Great deal for money. Excellent finish and optical clarity. A quality product.

Great optics, not so great accessories - 09/10/2014

by Phil W from North Bend, Oregon

We paid $265 for a demo pair. While we're still evaluating, our initial assessment is that these are the best optics we've seen for anywhere near that price.

The focus and hinge mechanisms are also smooth, while appearing sturdy. The covering material also seems durable while providing a nice grippy feel.

These bins fell a bit heavier than the Nikon Monarchs I've carried the past 4 years, but not out of scale with the improved optics. Plus the nice contoured neckstrap pad helps distribute the weight.

* * *

Turning to the accessories ... the field case Eagle provided is far superior to the plastic jewel display case the bins shipped in, but it's a bit too small for these bins.

The neck strap seems long enough for a moderately-sized giraffe, meaning each side is almost doubled all the way to the padded neck piece. Which is more distracting than troublesome.

The large-end lens caps are nice enough, but don't fit well in the aforementioned too-small field case. And the snap clip on one side's detachable cord broke the first time I unsnapped it.

The one-piece eyepiece lens caps would likely keep out dust and water at a molecular scale, but the tradeoff is that they're extremely tight. Which means they must be carefully teased off every time you want to view something. Or else you just leave them off, which defeats the entire point of them.

* * *

Since the optics are the main thing, on balance we're giving these bins four stars. But you'd think Zeiss could produce a better all-around package.

Most pleased with purchase. - 07/21/2014


This was my first purchase through Eagle Optics. After reading many reviews from other purchasers of various brands of binoculars, I decided to buy the Zeiss Terra ED 8 x 42.
Since I normally wear eye glasses in the field, I was drawn to the comments of other purchasers who praised the quality of viewing, while adorning their eye glasses. I am most pleased with my purchase. The field of view and the clarity are everything that I could have hoped for.

Zeiss Terra ED 8x42 Binocular with field case - 07/08/2014

by JUDITH S. from columbus ohio

Absolutely love these binoculars. Clear, crisp sharp pictures, easily handled and used. I have owned several brands and Zeiss Terra the very best at a good price. Also good customer service

Excellent value - 06/11/2014

by Kathleen from Oregon

I was delighted to try the Zeiss Terra ED binoculars from a friend in March. So much better than my own pair and I was very pleasantly surprised by the price. Since I received my own pair, they have been used frequently for birding and sporting events. I am very pleased, especially in how much light comes in. Thank you.

Couldn't be better - 06/06/2014

by Holly B. from Beaver Dam, WI

Really like the clarity and sharpness. Easy to focus. Lightweight. Have recommended them to a couple of birding friends. A good value for the money.

A fantastic experience - 06/03/2014

by Kah H.P. from Teaneck, NJ

I bought the Zeiss Terra ED 8X42 for my wife as we will be going on safari to South Africa. We tested it and it was not too heavy for her. The 42 mm objective lens meant that images could be seen even in dim light.I had to exchange for another as the earlier one that came was defective. I called customer service and the request for the exchange went smoothly and seamlessly and lo and behold, I got the substitute within two days! Thank you Eagle Optics. I am a very satisfied customer.

excellent binoculars for the price - 05/21/2014

by infrequent birdwatcher from North Dakota

I do not think one can expect more from a pair of binoculars for $350 (with case). I have Nikon Monarch 10X42 and Monarch 8x36 which I like. However, the ED Terra are brighter in low light than both Monarchs. The difference is not huge, but distinct. The image is crispier and the colors are better. It is not worth a replacement (I just needed another pair), but if one is trying to choose, I would recommend the ED Terra. They are not too heavy, stick well in hand and are overall high quality binoculars. This price segment seem to be crowded with several decent models, but I am certain that nobody will be sorry after choosing ED Terra.

Excellent for novice as advertised.

Zeiss Terra ED 8x42 Binocular With Free Field Case - 05/20/2014

by Ken B. from Ottawa, Canada

I use binoculars for birding.

I found the clear field of view visibly restricted to the centre of the glass, then quickly getting softer.
I found that there was no lock for the diopter adjustment.
The front lens covers were not very secure.
I found the focus adjustment too coarse.

Therefore I returned the binocular.

I compared this binocular to the non-HD vortex Viper 10X50 that I have used for about 5-6 years.
I now wanted a 8x42 binocular for closer distance work to view warblers.

After returning the Ziess binocular I bought a Vortex Viper 8x42 HD binocular here in Ottawa, so I could evaluate it outside the store.
I found it had good edge to edge clarity, was quite bright and have found subsequently that they are at least a bright as my 10x50s on dull days or at dusk.
Has lock for diopter adjustment, secure front covers and finer focus control.

More expensive than the Zeiss but has the quality and functionality I need for frequent birding.

So far, so good... - 05/12/2014

by Jim D. from Florida Keys

Really had hoped to find a decent pair of 7x in my price range and was really disappointed when Leupold pulled their line out of the Eagle Optics inventory, just a year or so earlier, Nikon had also ended their relationship with Eagle Optics. As the Leica 7x42 Ultravid HD and the Nikon 7x42 EDG Binoculars were well outside my budget, I was trying to choose between the Leupold 7x42 Hawthorne binoculars and (Eagle Optics) Atlas Optics Intrepid ED 7x36 Binoculars. The Leupold Hawthornes looked especially good to me, and Eagle Optics sales staff said they were a good choice for my demanding environment (sub-tropical coastline with salt air and frequent changes from air-conditioned vehicles to sweat-inducing heat and humidity).

But, placing a high value on the exceptional service I have gotten for so long from Eagle Optics, and unable to wait any longer, I ordered the Zeiss 8x42 Terra ED. Hopefully, Nikon and Leupold will reconsider.

This weekend I took them out for their trail run, volunteering to participate in a field survey for endangered Schaus' swallowtail butterflies.

So far, I am very happy with Zeiss Terra ED. They seem a bit s smaller and perhaps lighter than other (typically rubber-armored) 8x roof prisms I have held. Their minimum focus is less than 6 feet. I was half-anticipating and half-concerned about something I noticed in every on-line advertisement I had seen for the Zeiss Terra ED: the objective lenses appear to have a red tint in every photo of these binoculars. With some relief, I can say there is no red lens-coating. I am still not sure the field of view is optimal for butterfly watching (especially for small, erratic-flight species like the Cassius blue butterfly), but I'm willing to give that more time.
