For the all weather birder - waterproof is not a luxury it is a requirement.
I worry less about rain than mist and internal condensation from weather changes etc. which penetrates everything.
I like the Zeiss – small knob was not a problem for me. I agree with Alexis, mine showed internal reflection or flare when viewing back lit subjects. Here in the USA the Zeiss come with a lifetime transferable warranty so if that applies in your country it might make an Ebay purchase more attractive. Other than back lit the image was excellent.
BUT after reading APs posts about the backlight situation I tried the Ultravid and sold the Zeiss after comparison in back lit situations. The advantage on backlighting the Ultravid had was big enough for me to make the switch.
The Zeiss fabric case is still available in the USA I prefer the fabric case and use it on the Leica and Nikon 10x25s we own.
http://www.bhphotovideo.com/c/product/328208-REG/Zeiss_52_90_33_Victory_10x25_Binocular_Pouch.html I can open it with one hand and take the bins out with one hand. This is a big help when holding the bicycle (or a drink) with the other hand.
Having owned all 3 of these bins I can say they are all worth the money in my opinion.
They are tack sharp and provide constant joy in my life. I have not seen any credible reports that the Trinovid is superior or equal to the Ultravid. I do admit that some eyes can not see the difference so I justify my opinion that way.
To my eyes the Ultravid and Nikon are the leaders of the 3
On a small binocular like these (which are not a replacement for a larger binocular when available) I expected to make some compromise.
In my mind the compromise on the Zeiss was the backlighting flare. But a great view in other conditions. On the Nikon it’s the neck strap attachment point (not a big deal at all). It comes with a leather case too (silent magnetic closure) which we dumped in favor of the Zeiss nylon case with noisy Velcro. Focus knob on the front was a non issue for me.
On the Leica I somehow feel the view is a little cramped to my eyes when compared to the Nikon. But the Leica is my favorite (I do sometimes switch that opinion to the Nikon at times. But I limit myself to changing my prefrence to 5 times a day).
On the positive side –
The Zeiss are very rugged and waterproof. Nice eyecups. Very light weight (glass reinforced composite body) I have focused them with gloves on – no problem. The off center fold point and knob were not a problem for me. They felt good in my hand and on my face. Love the fabric case enough to buy it for my other small bins.
Nikon is built like a truck. Great visual focus. The bird pops into sharp focus. You know when you’re dead on focus. Nikon is the only bin in this size that uses ED glass. Some may disagree but I see superior color due to the ED glass in low light. Focus knob is not a problem The view is easy on the eyes and feels more spacious when you look in them. Cost vs performance leader! T
Leica Small compact and an a view that is equal to the Nikon or superior depending on what your looking at. Flare is well controlled (but there is still some. Eye cups are slide up rather than twist up. I use the Leica nylon case when walking and the Zeiss case when bicycling.
If you purchase any of these 3, I doubt you will be let down. If you think at all you may be using these often – I would go for the best glass I could afford (even if it means saving longer or selling something you do not need as badly - like a kidney). They truly are a joy to use.
If I had it to do over I would go with the Ultravid or the Nikon. But I could live with the Zeiss.
Have fun!
