Yes!
I would say that, in some chapters, the Ultravid 8x20 is even better than Curio 7x21! I would start with the subjective one related to
design. For lovers of pocket binoculars, the jewel aspect is obviously in favor of Ultravid. Curio has a somewhat unfinished design, giving the impression of a pre-launch product design.
Another important aspect for some is the
ability to focus at a shorter distance of Ultravid (1.8 vs 2.5m). Many do not use the binoculars at such short distances, and then it does not matter to them.
Also, the differences regarding the focus wheel seem very important to me. Ultravid has a
larger focus wheel, which is much easier to access than Curio wheel, which is buried in the body. I consider this aspect the most important difference related to the ergonomics or handling of these two small binoculars, because the focus wheel is our interface with binoculars.
Of course, there are several differences starting only from the difference in magnification, but these are a purely personal and subjective choice. Thus, due to the lower magnification, 7x has a
larger depth of field and a
much wider FOV (7.7 vs 6.5 degrees). But the AFOV is similar in these two binoculars, so the tunnel feeling is very similar because this is given by the AFOV, not the FOV. In this aspect, both binoculars do not excel with their slightly above 50 degree AFOV.
The difference in the exit pupil is not that big, but it is there (3mm vs 2.5mm). Anyway, these very small pupils like 2-3mm are more similar than different, because they are ok only for use in bright conditions!
So for me the important differences are the following:
Design and mechanics: Ultravid>>Curio,
Focus rotation access: Ultravid>>Curio,
Close Focus: Ultravid>Curio,
FOV: Ultravid<<Curio
Depth of field: Ultravid<Curio
When it comes to the optical performance of these two pocket binoculars, I consider them both in the same class of top optics! Appreciation of optics depends more on everyone's preferences, especially when it comes to color rendering, field distortions or other subjective preferences!
Returning to the question of the topic:
"Leica Pocket like all purpose bino?"
I couldn't say a big "yes". But if we want a pair of binoculars for sunny weather, very small, with top optics, so that we don't feel its presence around our neck or in our pocket, having it permanently with us, then this type of binoculars with a very small exit pupil like 2- 3mm are perfect, big "yes"! But if we are willing to sacrifice a little more space in the backpack and a little more weight on our neck, then an 8x30/32 binocular is more useful in worse light situations and much more comfortable to use! Than "no". Everyone's priorities matter! Depending on the situation. That's why we have several binoculars.
However, in the extreme situation, I can imagine myself with only one pocket Ultravid 8x20 binoculars, why not!
