Hello together,
I just want to share my experience with premium binoculars.
My first one was an old bulky Zeiss 10x50, multi-coated, I got from my grandpa. He bought it long time ago in former East-Germany (GDR), at that time pricey around 600,-DM. I felt in love with binoculars and nature observing as a child.
When I got older and could afford binoculars on my own, the first one I got was a SF 10x42. Later I got gifted a Victory Pocket 8x25. Later I also bought a SF 10x32, which I have since 2 months now.
What I love about the SFs, in general
I love the crisp, sharp, natural colored images and the very high resolution. Zeiss knows how to build high quality optics. (Sure Leica and Swarowski, too.)
The wide field of view contributes to the immersion, and Zeiss knows how to, let´s say, create a "3D-Effect" that let you feel that you are really there. You forget that you look through a binocular. They are superb balanced, you forget that you use a binocular, when looking through them. The focuser is also smooth.
The 10x magnification with the very wide AFOV, increases the immersion for me.
Differences SF 10x42 and SF 10x32
My former primary the 42, is still lightweight for a 42, but when you carry it on a long hike, you notice that you have "something" on your neck or in the harness. But when you take it to the eyes, you immediately have a perfect image. The 32 needs to be setup precisely (IPD and eye cups) to get a similar experience. Now I use my 42 when I am explicitly looking for wild animals (like deers) during twilight, there is no real other benefit with the 42 for me in comparison to the 32, at day and also until sundown. The SF 10x32 works for me until around 10-20 minutes after sundown (depends on the weather condition). I am not a hunter so that's ok for me. It's designed as a high-end instrument for the day.
Well I compared them side by side, multiple times, during sun goes down. And the SF 10x32 works remarkably well. As long as your eye's pupil did not exceed the 3.2mm, then the 32 is just slightly darker than the 42, I assume this is not because of the exit pupil, it's most likely because of the +2% light transmission. Well these 2% I occasionally notice also during dull dim days. but it does not bother me, you can see all details via the SF 10x32, clearly and crisp. I love it. It's so super lightweight, and fits for my big hands like a natural plug able extension of my eyes.
I read that some users experience "blackouts" with it, well you need to setup it for your eyes and eye socket shape, correctly.
What I love with the small VP 8x25
It's even lighter and used when I normally would not take a binocular with me. It's a "you always have with you" binocular. I use it also in urban areas, where 8x is usually enough. But when I use it in nature, I often think "would have been nice to have 10x now, damn". But the general rule is "the best bino is that that you have with you".
The 8x is more stable, it's like I would use a tripod. But I got comfortable with my 10x bins to hold steady with bare hands. It's just a matter of training. The wide field of view which my 10x offer does not require for my needs a 8x32 or 8x42.
Comparison to NL Pures I tried at the dealer
Sure, they are also awesome but they are heavier, less balanced for me and the view is like a flat screen TV. If I want to watch a movie of nature, I watch it on my flat screen TV. If I want to experience nature as it is, I use my SF 10x32. If I want to search for wild animals at twilight I use my SF 10x42. If I go biking I use my VP 8x32....
If I would ever go to a long expedition, I would take the 32 at standby on my neck or in a harness AND probably would take also the 42 in the backpack with me, just in case for late twilight.
