BINOCULARS - SAFARIIf you are a Birder, you obviously need to take binoculars.
MY OPINION: If you are on an African photo Safari, AND everyone has a
decent camera, I WOULD NOT TAKE BINOCULARS - TOO MANY THINGS TO DEAL WITH
and a decent zoom camera, has more zoom than your binoculars - Canon SX50.
Also, you will be too busy looking and taking pictures to change
to binoculars. If you are using binoculars, you may easily miss
your camera opportunity. Other people may not agree with me.
I strongly urge you to consider binoculars that are both WATERPROOF
and that will not fog (FOG PROOF), and that are as light as possible for the
type of viewing for which you need them.
Personally,as a personal opinion only, I do not like Bushnell binoculars.

Most of this information about Binoculars for Safari use comes from
OR www.safari-guide.co.uk - These are two terrrific sites for Safari
Information - I suggest that you peruse them thoroughly. Either of
these sites can help you put together a really great safari. There
is much more Safari related information at their sites.
Besides these factors
A] Field of View ("width" of your view at a specified distance),
B] and the magnification - I recommend either 8x42 or 10x42
C] The types of prisms used (should be fully coated)
E] FOG PROOF
F] SHOCK PROOF (probably really Shock resistant)
G] Light-weight - can you hold it all day while you search?
H] Has a strong palce to attach straps and should come with straps
I] Should have lens caps to protect the lens
J] Should come in a protective carrying case
There are Three other major an done minor criteria for you to consider,
that you probably have not even heard about.
1] EXIT PUPIL SIZE
2] EYE RELIEF
3] TWILIGHT FACTOR
4] Consider Image Stabilization - not cheap, but getting cheaper
Safari Binoculars - How To Choose the Best One
So based on all these factors this is the best binocular to take with
you on an African safari:
Magnification: 8 x 42
Field of View: At least 330 ft at 1000 yards.
Exit pupil size: 5.25 mm or more
Eye relief: 18 or more
Prism and Coating: BAK-4 prism and Fully Multi-Coated surfaces
Weight: Not more than 30.1 oz. lbs.
The following three brands conform well to all the specifications above and I,
(Bruce Whittaker - african-safari-journals) recommend them highly for an African
Nikon 8x42 Monarch ATB - $ 228
Minox BV 8x42 BR
Bushnell 8x42 Legend Waterproof/Fogproof
Safari Binocular Reviews - Safari-Guide
EXIT PUPIL SIZE - BinocularsEXIT PUPIL SIZE - safari-guide.co.uk
EXIT PUPIL SIZE
"This is basically the amount of light that enters the objective lens
(big lens at the end of the binoculars) and then exits the ocular lens
and into your eyes. It is an important measure if you want to know how
well a binocular will perform in dim light." - By safari-guide.co.uk.
An Exit pupil size of 5.25 mm or more is recommended by African-Safari-Journal
EYE RELIEF - BinocularsMid-sized Binoculars and Eye Relief
"Eye relief is the distance from the eyepiece to the point where you can
see the whole picture. People who wear glasses often have trouble using
binoculars, because their glasses hold the binocularís eyepiece too far
away from their eyes. Itís a problem with many binoculars, but
particularly with smaller ones." There is much more such information
at their site - Michael and Diane Porter at www.birdwatching.com
"Non-line or progressive bifocal glasses make it almost impossible to
"By way of example, the Celestron Noble 8x32 was one of the best in eye
relief of all the binoculars we looked at. With its eye relief of 20mm,
it affords the full field of view, or very close to it, even to glasses
wearers." - By birdwatching.com
BIRDING and EYE RELIEFEye Relief and Birding Eyeglasses - birdwatching.com
"Normal eye relief for binoculars ranges from 9 to 13 mm. Even though
the eyecups of most binoculars fold down to let glasses wearers get
closer, in many cases, it's not close enough. If you wear glasses, you
need binoculars whose eyepieces are specially designed with long eye
relief, which manufacturers describe as 14 mm or longer.
Obviously, if you are a birder, you will want as much magnification as
you can afford and that you can carry and use all day. You also want
the lightest binoculars that do what you need.
Some birders prefer 10x50 - these are definitely heavier and harder to hold
TWILIGHT FACTOR - BinocularsTwilight Factor - astronomics.com
TWILIGHT FACTOR - How well your binoculars work in LOW Light
"A number used to compare the effectiveness of binoculars or spotting
scopes used in low light. The twilight factor is found by multiplying
the size of the objective lens (in mm) by the magnification and then
finding the square root of that result.
FOR EXAMPLE, a pair of 8x42 binoculars has a Twilight Factor of 18.3 - DRW
The larger the twilight factor, the more detail you can see in low light.
A twilight factor of 17 or better is usually required for reasonable low
light use." - quoted from astronomics.com
RECOMMENDED SAFARI BINOCULARS (good, but not expensive)I, DRW, chose the Nikon TrailBlazer 8x42 ATB Waterproof Binoculars.
We were quite happy with these. They won't reach as far as some of
the bigger "glasses", but they are very comfortable, and I am not
interested in seeing beyond the distance of my camera lens, if
I can't take it's picture, I am not interested in seeing it.
