How Does The Zeiss Conquest HD 10×42 Compare With Vortex Razor, The Terra ED Or The Swarovski SLC WB?

vs. Terra ED

The overall build quality of the Conquest HD series compare to the Terra’s is more advanced. The diopter setting, focus, twist-out eyecups are more solid as well.

More importantly, the Conquest glass is better which is where the great difference lies. These better features will result in less eye strain and give you a more enjoyable experience overall.

vs. Swarovski 10×42 SLC WB

Swarovski and Zeiss would of course have their differences, as both have their strong points and subtleties in their product ranges.

However, glass wise, the clarity of the Zeiss Conquest 10×42 is comparable to the 10×42 SLC WB from Swarovski. You won’t even see the difference. The clarity of the lenses are equivalent.

There is of course one big difference between the two – the price. The Swarovski model is more or less, a thousand dollars higher in price than the Zeiss’.

If you’re a Swarovski fan and you can afford it, by all means go for it but if you’re into quality and performance at a better price, then the Zeiss is a very good option.

vs. Vortex Razor 10×42

Based on people who have tried both the Razor and the Conquest models, it was concluded that the optical quality of the Zeiss model is more superior compare to the Vortex.

Also, the focus knob of the Conquest HD 10×42 is more sensitive than the Vortex Razor 10×42 which makes focusing and adjusting a lot easier, even with one hand.

Lastly, if you’re comparing the Conquest HD series to other brands, it is reassuring to know that there was a test conducted by Cornell Ornithology Lab and they have concluded that the Zeiss Conquest is the best in their price range.

They have indicated that these are very good binoculars. The clarity and depth of field are outstanding. Suffice to say that you’re in for a good treat with this binocular from Zeiss.

What Is The Warranty For This Model?

This binocular is covered by Zeiss’ No Fault 5 Year Warranty policy. After that, it transitions into the limited lifetime warranty which is really a pretty good deal.

Great product with an awesome warranty, you don’t really have much to lose in here!

Negative Feedback:

Reading through various feedbacks from users, the following negative comments were noted:

  • Lens covers are cumbersome and won’t stay on especially while using the binoculars with a chest harness
  • The strap that came with the binoculars is not that comfy for some users
  • There are few users claiming that there are physical damages (out of the box) when their binoculars arrived such as scopes are out of alignment, cracked rotating eyecup and scratched lens (which are all covered by warranty anyway, so shouldn’t be a huge deal)
  • While most of the users find the focus knob easy to use, some people find it as so sensitive to operate
  • Eye cups could not be raised high enough
  • Some users say that after-sales support is not that great (although there are many more other users saying otherwise)

Some Notes From Users

We’ve gathered some salient points from users’ comments. These are not negative feedbacks but pretty handy to know firsthand before deciding to buy this model.

  • Some users prefer the Cabela’s Pro Binocular Harness Item: IK-711764 than the one supplied with the binocular as it is more comfortable to use.
  • Some users would like a longer eye-relief capability. Take note that the eye-relief of this binocular is 18mm (which would fit most people who wear eyeglasses) so if you need more than that, you have to go for another model or brand.
  • Other users find the fairly limited selection of accessories from Zeiss (i.e. eye cup covers) as opposed to other brands a bit of an issue. (Although this was easily fixed with a solid covered harness purchased from other suppliers).
  • Some people found out that installing a slide-on flip up cover for the outer lens protects the binocular from scratches better than the ones that came with the package
