About 6 years ago I was migrating slowly to higher bino powers, but hesitated to buy a 20x80 pair due to weight. So, I found a used pair of Japanese 20x50s to get oriented to using this magnification. I found the exit pupil was usable on brighter open clusters, the moon and especially the sun. I own a pair of mylar solar filters for these binos, it's one way to quickly preview the solar disk before setting up a scope.

I didn't find daytime views were difficult, it did take some effort to figure out the balance/stability issues. Actually this pair was a surplus military binocular so I am sure they served a useful purpose for daytime surveillance.

So, my experience seems to suggest a place for 20x50s... I've since migrated to 20x80s but occasionally pull out the 20x50s for certain objects.

Meter readers use such instruments to read meters that must be read from a distance; it sure beats climbing every power pole in the county.


There are those out there who couldn’t care less about the night sky.



check out ships when we are down on the waterfront.


keep our eye on the Americans who are to the north, east and south of us!



viewing cityscapes, and I'd be doing just that with a 20 x 50

Excellent, thank you very much for this feedback, I assume these real world uses are from people without the profile of reading binocular astro and birding forums, explained them the relative lack of topics on this format. In reality, running a search engine query with the term "what's the point of a 20x50" and the results will return this topic.

Loren Toole, thanks for talking about one astro related use.

Answering the "open agenda" secondary question, a binocular to watch, near home bird nests, mounted. I assume the quality side is a little step heavier on aperture, 60mm have a lot of quality models, most of them focus close enough.

A "hidden agenda" question is the fact I read somewhere else people recommending 20x50 as a great binocular to start on astronomy
So I wasn't sure if I was the only one that think these aren't perfect binoculars to start on astronomy, now I'm at least assured I'm not the only one

It is possible that those models don't work at full aperture and magnification, they may be something like 17x43.

I just noticed a Pentax 20x50 Selling on eBay.

I also noticed that it said "Made in China."
