[net.consumers] Binocular Summary

ecl@mtgzz.UUCP (e.c.leeper) (08/03/85)

I asked for recommendations on binoculars to take on a trip to South America
(Amazon and Galapagos), to be used primarily for viewing wildlife, small,
lightweight, resistant to water damage, and not too uncomfortable for people
who wear glasses to use.

Thanks to all who responded--I have a much better idea of what to look for,
etc.

The responses I got (some editing for conciseness):

Nikon binoculars are excellent.  I just acquired a pair of 7x50s to use on
Halley's Comet this winter; they're nice, but *heavy*.  The smaller Nikons
should be excellent for daytime use.  Dunno about Bausch&Lomb, but cheap
binoculars, I've found, give me a headache.  Btw, when evaluating them,
pay especial attention to how close/how far apart the two eyepieces can be
set.  Look also for a separate additional focus for one eye; that lets
you omit your glasses (if that's a concern).

We have had absolutely no luck getting replacement parts for a pair of
Nikon binoculars.  We initially didn't want anything fancy---just a
replacement set of eyecaps.  Subsequently, we also needed a replacement
bracket (the original broke).  Writing to the Nikon distributor for the
U.S. resulted in no response at all.  We've written several times and to
several different addresses.  I don't think I'd recommend them because of
the difficulty in getting hold of them if you want to.

I have a pair of Nikon 7x26 compact binoculars.  They are wonderful.  The
field is extremely wide, and the image is very crisp, though soft at the
edges (not a problem because the field is so wide).  They are light and
compact.  I paid $200 for them six years ago but foreign exchange has
driven the price down to about $150.

If you want REAL compact, consider the Leitz 8x20BC, available for under
$200.  When folded up, it's about the size of a pack of cigarettes.  The
image is extremely crisp, but the exit pupil is small so you have to be
careful how you use them and they're not too useful, say, from a moving
car.  I would definitely prefer the Nikons for night use because of the
extra light gathering; I would probably prefer a pair of 7x50 even more if
I could get someone else to carry them.

Well, as far as binoculars go I'm not a great one to ask.  I bought my
binoculars when I was poor(stil in high school) so they are not high-qual
equipment.  But I can give you a few pointers on buying binoculars in
general.  For bird-watching I would say go for a 7x35 or 8x40.  8x40 give
you better detail, but cut down your field and don't work as well in low
light.  (They may or may not be a big consideration for you.  For a
bird-watcher who wants to make a definite identification low light may
mean the difference between a 99% sure guess or a wild-asses guess.)  I
have a pair of 8x40 since I like the detail better.  I used to own 7x35
and found I was getting a good enough picture of the birds.  

Get coated lenses.  They cut down on glare and also protect against
scratches.  When you look through the binoculars make sure there are no
rainbows.  Means cheap lenses and you're getting weird diffraction
patterns.

I have never looked into wide angle lenses but I hear they are not worth
it.  Personally, I would find them annoying since I can't focus on a huge
area all at once anyway.  I don't know that  anyone can.  When looking at
things far away you generally can't take in the whole scene in one glance
anyway.  I think wide angle binoculars have their biggest fans in sporting
types.

A nice feature that I have on my binoculars is a second focus.  The dial
is marked 0 in the middle with a few notches on either side and a + and -
on either end.  This focus is to compensate for you own eyesight.  You
focus with the main focus on something close by.  Then you move the
secondary focus until the picture becomes clear.

Try Nikon Lightweights.  Fairly expensive (list), but very good and light.
They look a bit like Trinovids, but are cheaper.  BTW, a way to test binox
is to look into the eyepieces from 2' away.  If you see a full circle of
light, the optics are designed for maximum light throughput.  If the
circle has a brighter square in the middle, then there are apertures which
cut out some of the light, and the binox are not as good.  Try this test
with real cheapies and known good ones and you'll see what I mean.

The best kind of binoculars are the non-prismatic type.  These 
instruments use higher quality lenses to achieve equal power in a 
smaller, more durable package.  Non-prismatic binoculars will last longer
and produce less eye strain when used for long periods.  Unfortunately,
these binoculars are much more expensive.  I have used Leitz armored
(these have a tough, rubber coating) which run about $400 and have been
very satisfied.  For a cheaper alternative you should look at Japanese
non-prismatics - I think minolta makes some of these.  Finally, remember
that the higher the power of the binoculars, the more tiring they will be
to look through since they must be held very steady.

If you can get them, I would recommend Tasco 7x35's.  They can usually be
found in dept. stores, usually for under a $100.00.  The Tasco 7x50's
would be better, because they have a wider field of view and greater light
grasp (especially useful if looking into areas of *relative* darkness),
but they are a bit bigger and heavier.

As a second choice I'd pick the Bushnell's 7x35 (7x50 if you don't mind
the extra weight).

I bought the Leitz Black Compact Armoured 10x25 binoculars from 47th
street camera last October for around $170.  These would fit your
specifications very well except for the eyeglasses but what I do is simply
take off the eyeglasses and view directly.  The binocs will nicely
compensate for any aberrations in your eyeballs.  I have cataracts
(removed) so I'm pushing the limits of this technique.  Interestingly
enough the Leitz compact bincos focus the closest of any I've tried when I
do this.  When it comes to optical glass, whether camera lenses or binocs,
there is Leitz and everybody else.  To say they are superb is an
understatement.  You'll never want to look through any other glass after
experiencing these.  They are covered in black hard rubber.  Hermetically
sealed against moisture, I believe, but not waterproof.  And they fold up
into a package little bigger than a package of cigarettes...well a big
package anyway.

I bought a pair of Nikon C.F. 7 x 20 binoculars at the end of june.  I
paid $75 at a local camera shop.  I highly recommend them though I'm sure
you can find a lower price in the city.

I'm satisfied with my purchase; they're small, light, and easy to use.

I used Bushnell Ultralight binoculars with thumb focus (they call it Quick
focus or something) in the Galapagos and they worked quite well for me.
Nikons are good binoculars and also somewhat smaller and also somewhat
more expensive.  I prefer the standard size binocs as they usually have a
larger field of view (mine are 7x30), and they also have better light
gather properties for use at dawn and dusk.  7 or 8 power is the best as
holding more powerful binoculars steady enough to see anything can be a
problem.

I just bought a pair of 7X35 Nikons.  The optical quality is every bit as
good as the optical quality of Nikon cameras.  I think Swift and  Bushnell
are noticeably poorer in quality -- the image is less sharp and  the lens
coating is less effective at reducing glare.  The only complaint I  have
with my Nikons is that the width of field is smaller than what I am
accustomed to.  

When I bought my binoculars I seriously thought about getting a
magnification stronger than 7X.  Stronger magnification is especially
useful with sea and shorebirds.  The problem is finding a binocular with
powerful magnification and sufficient brightness.  Zeiss makes an 8X56
binocular which I think is ideal, but it is out of my price range.  Leitz
makes an 8X40 which is rumoured to be nice but expensive.  Swift makes an
8.5X42 which has decent optics, is moderately priced, but is on the heavy
side.  You might also be interested in some light (and waterproofed)
7X42's made by Leitz and by Zeiss.  These will be brighter than 7X35's,
but like all Leitz and Zeiss binoculars, they are also quite expensive.
Magnifications over 8X tend to get either heavy or dark or  both: some
people, however, are quite fond of 10X40's.  Then there are all those tiny,
compact models -- I didn't look at these, but a friend has something like
a 9X25 Nikon which is quite sharp, delightfully small, but a little dark.

I have a very small, light, inexpensive pair of Bushnells (7x15?, 7.1
degree field).  They work wonderfully for hiking/backpacking/travelling
and really improve the view.  $35 or so at your local LaBelle's or
equivalent.

While I have had a pair of Bushnell binocs for several years now, and have
enjoyed trouble-free life with them, a friend of mine went to get his wife
a pair for bird-watching recently and I went along.  (He ended up getting
somebody's "Audibon" model - very popular with the bird crowd)  Mine have
two features that were called suspect by the guy at the store, namely a
zoom from 7X to 15X and a focusing lever (instead of the more common
dial).  Obviously, zoom optics must have moving parts and may therefore
become misaligned.  There were two objections to the lever focus.  One was
that it is impossible to do with one hand, while it is possible to rotate
the dial with one hand.  The other was that the mechanism for the lever to
work is based on a sort of cam, namely a grooved bolt inside the focusing
mechanism that is moved forward and backwards by a pin sticking out from
the lever.  This will develop play after a while, which will make focusing
more difficult.  Like I said, though, I have had no problem with mine over
four years of light use, and I still enjoy the advantages of these
features.   Namely, the lever makes it easy to focus in a hurry (overshoot
and come back) and the zoom is really nice for spotting a bird (etc) on
low mag, then zooming in on it for a closer look.  I have also enjoyed
this when star-gazing.  The only other thing I can think of to look for in
a good pair of binocs (besides top quality coated optics) is the f rating.
This is a sort of measure of the light-gathering ability of the optics,
and will be a limiting factor on what you will see well.  The ones with
better light gathering ability are necessarily larger (they will have a
'jog' in the light path so the objective lenses are further apart than the
occulars, and the objectives will also be bigger for the same power of
magnification).  The smaller, more portable binoculars simply can't have
the same performance here.  From experience, the size makes very little
difference unless you are dealing with pocket-sized opera glasses (forget
it) or really huge glasses.  A good idea is to get a 7X pair for looking
around and a spotting scope for the serious stuff.  Each should run around
$200 +- $30 (at least around here).

Mom just sent me a pair of binoculars from sears.  They're roof prisim
design so very small.  They fold up even smaller, and are quite light.
Optical quality seems good to my untrained eye, and they only cost $47.
It is impossible to see through them with glasses on and I think that this
will be true of anything but very large heavy binoculars.

I've had a Bushnell Custom 7x35 Binoculars for over ten years and have no
complaints.  I use them for birding and going to the opera.  They aren't
particularly small or lightweight, but seem to take heavy use well.  I
haven't used other Bushnells in a couple of years, but I really did
(*not*) like their compact model or their lower priced lines.  I'd avoid
their insta-focus or  whatever-they-call-it feature and stick with the
basic, high end model.

If you want a good compact set of glasses, consider the Leitz trinovids.
They're wonderfully clear and bright, but about twice as expensive as the
price range you suggested.

I have the Nikon 10x? binoculars. They are excellent.

My father recently bought some binoculars made by Nikon and they are by
for the best that I have ever used.  They are sharper than any I have used
before.  Here in the San Diego area he was able to get the pair that he
bought for about $90.  They are good for use by glasses wearers because
they have a eye cup that will fold back out of the way.  My father had
this in mind particularly when he went looking for binoculars since he
must wear glasses and he is quite satisfied with these binoculars.
