Close focusing binoculars ?

Hello Group ,

I would like to find a pair of binoculars that focus down
to about 8-10 feet or so . I would like them to be in the 10 power
range 10X40 would work just fine . They would be use like a distance
microscope for viewing insects and my aquarium from a distance. If
anyone has any ideas please let me know .
Thanks , Leonard

Hi Leonard,

The Leica 10x32mm Trinovid BN are listed with a close focus of 7 feet.=20
Mine seem like they focus even closer than that. And i do often use them
as you mentioned as a sort of long range microscope to watch insects=20
or study desert plants. They are my most used daytime binocular. But=20
they aren't cheap. I got mine from Astronomics...

There are quite a few binoculars which focus down to 10 feet and some
considerably closer. These are classic "birding" binoculars. Just about all
binoculars that have good close focus are going to be roof prisms.

For example the Eagle Optics Ranger Platinum 10x42s have a close focus of 5.2
feet.

These are not inexpensive, $399, but they are good quality and they have an
unbelieveable lifetime warranty, no paper work needed, fully transferrable and
they fix it no matter what. If its your fault, it will cost you $20.

Eagle Optics carry just about every binocular made and they have full specs
their website www.eagleoptics.com

Another option for close focus is small refractor. With proper spacing these
will focus as close as you want and magnification can be easily changed. With
binoculars one runs into the difficulty that one can be so close that the right
side and the left side are looking at significantly different fields of view so
a telescope maybe the best tool anyway.

Don't you get a sense of being cross-eyed? Binoculars are either
optically aligned parallel for infinity or pointing inwards for closer
use. Aren't they?
Perhaps a small pair of roof prisms doesn't suffer from parallax
effects like the porro prism jobbies with their widely spaced
objectives? :-)

A bit. But if i was holding something in my hand and looking at it
my eyes would also be crossed. I just used the Leicas to look at a
liquid paper bottle on a nearby table. The magnification and feeling
of crosseyed-ness is about the same as if i was holding the bottle
in my hand a few inches from my face.

About this crosseyed-ness at close focus , if one
were to focus out two or three feet from closest focus would not this
effect lessen alot ?


Hi Leonard,

Yes, i only notice the crosseyed feeling when at very close distances.
But it's not a bad feeling. It's just normal when you're looking at
something close.
