Latest reviews

  • stunning sharp, wide fov, excellent close focus, well built and lightweight binoculars
  • some glare issues, eye placement slightly tricky
I bought these in the 10x42 format to compliment my Swarovski 7x42 SLC's, and since I bought them I've not yet used the Swaro's!
The image is wide (for a 10x it is quite astonishing), super sharp, bright and with excellent colour renditioning. The edges on these binos are often referred to as "soft" but as I look at birds in the centre of the image, I really don't notice this. They work extremely well with glasses, which was a very pleasant surprise, and I can see the full fov. They perform very well in low light and dull conditions, and I have used them at gull roosts after sunset. The close focus is exceptional - less than 2m!
They are very well constructed, and feel very sturdy and well balanced.
There are two negatives that I can think of: 1) eye placement and 2) glare control. The first "issue" is not major and more likely due to the smaller exit pupil than I am used to. When focusing in the mid to long distance and then focusing to the extreme close range I have to adjust the IDP in order to get a comfortable (and full) image. It takes a split second longer for me to get onto birds I believe also as a result of the smaller exit pupil, but again perhaps with more time in the field this will become less of an issue. The second issue is slightly more serious - glare and stray light control. When looking directly below the line of the sun (e.g. on a winters day looking toward the sun at midday) there is some noticeable glare and stray light in the left hand lens. It's not something I have read about before, so perhaps is down to the combination of the shape of my glasses and my face. I've not used the binocular in different climates or seasons (yet) but I suspect that this could be an issue in strong sunlight or high contrast areas (e.g. in a forest clearing in the tropics).
Altogether I would rate this bin very highly, and I can see it fast becoming my main bin ahead of the swaros. I will report back in a few months when hopefully I will have been able to try it in different environments.
  • bright, sharp, amazing FOV
  • Had to return for service due to fogging
I took these bins on a multi-week sea kayak expedition in Baja, and they fogged upon my return to the states. I sent them back to Zeiss, and they were refurbished and returned within two weeks in marvelous condition.

I teach natural history courses at the university level, so I used my old Zeiss Night Owl 8x56 bins during the interim when the 7x42s were out for service. Until then I didn't realize how much I'd come to love the 7x42s, especially when inside forested biomes. It wasn't just about the weight; I find the 7x magnification far superior to 8x in terms of depth of field, field of view, and steadiness. I was missing small insectivors in dense cover with the 8x that I'm certain I could have followed with the 7x.

None of the alpha bin manufacturers is currently offering a 7x, and I think this is a mistake. Watching to see who will step up to fill the void.
After about 4 years (and not 10 as I hoped ;-)) I traded this one in for a new Nikon EDG (II) 8x42). Please see my review over there. In short: richer colors (Zeiss almost too bright, too white), sahrper, handling, focusknow.
