One more for the "wow the UV 32 is tiny!" files, I posted this on another thread but here's a size comparison between the UV 32mm, Nikon EDG 32mm, and the Leica Trinovid BR 42mm (same size as UV 42).
As you can see, a large 32mm like the EDG or Swaro SV dwarfs the little UV (and, by extension, the FL) in length!
To Gwen's question about why someone would buy this vs a compact 42mm....
Well, since I happen to have not only that 32mm EDG, but also an 8x42 Monarch HG on hand... my thoughts:
First, despite the extra length, the Zeiss SF (as well as the Swaro EL SV) weigh only ~600g (~21oz) so they are still considerably lighter than almost any premium 42mm. The EDG is a bit porkier at ~650g (~23oz) so the gap is lessened, but the difference between even a 25-26oz binocular (which is light for a premium 42mm) and a 21oz binocular is significant when carrying it around and holding it up to your eyes for several hours.
Second, while it may seem tempting to wonder about a light-weight 42mm, the truth is the Monarch HG is really an exception. My 8x42 MHG is crazy light at ~665g (weighed on my postal scale) so it's only ~15g / ~0.5oz heavier than the 8x32 EDG.
But what else is there? The Vortex Razor HD 42mm is the only other "premium" 42mm binocular that's under 700g that I can think of.
And both the Razor HD and Monarch HG are *excellent*, but they are NOT alphas. For those who appreciate the difference, it is there. The MHG 8x42 is much more practical, and obviously much brighter and easier to use in low light vs the EDG (which is a 10x32, so even more of a low light penalty) but the EDG glass is on another level vs the MHG. It's not "night and day", but the EDG glass is better.
So let's say you're someone who values "alpha" optics? Now the $1K Japan sub-alphas are out, so there are no more light weight 42mm options. The lightest and most compact 42mm alphas (Leica UV, Swaro SLC) are still in the 27-28oz range. And the 42mm flat field uber alphas (Swaro SV, Zeiss SF, Leica NV) are on the long and heavy end of the 42mm spectrum.
So, to answer the question, "what is the point/benefit of purchasing such a large 8x32mm binocular over, one of the latest high end compact 42mm roof prism binoculars you can buy today from Japan or else where ?"
I would say the answer is "when you want no-holds-barred premium alpha optics, but don't want to carry a big, long binocular that weights ~800 grams". There are many who swear by the Swaro SV EL 8x32 as the best all-around birding binocular on the planet, and it's the same weight and just a bit shorter than the SF 32.
For some people (me included) weight is more important than physical compactness. I am not putting my binoculars in my pocket or in my bag, when I'm birding my binoculars are out. But I notice a major difference carrying around and hand-holding the MHG 8x42 (665g) or EDG (650g) vs the Trinovid (800g). Even more so with a ~600g binocular like the Kowa Genesis. And I bet the Zeiss SF "feels" even lighter in the hand, since that weight is spread across a much longer frame.
