For 20 years, I've used a 8x32 Trinovid which is very small. I recently bought a NL Pure 8x32. It is 3cm longer and in my bag or around my neck, it does not make that big of a difference.
And I prefer the handling and bigger ER of the swaro (I would have bought an Ultravid 8x32 if not).
If I want something compact, I also have the Zeiss Victory 8x25: size & weight allow me to carry it into a pocket and forget them, something harder with a 8x32.
Yes, Yes ... in hand and at the face it may not make a difference. However, a slight minutia of size may make a big difference in the jacket or hoodie pocket. Maybe snag up more and not able to quickly deploy or put back, or maybe no longer fit altogether and have to carry around the neck, or maybe that convenient pocket on the outside of the day pack no longer works and must be carried in the main compartment amongst other gear. Yes, Yes ... 8x25 resolves all these issues and more. But maybe some find the ergos of x25 so off that they cannot be considered. This is the downside of the enlarged x32 for me. I suspect some others feel the same. Luckily, x30 seems to be filling this spot. Will a so called large x32 cannibalize the x42?????
