Anybody know of a binocular that has interchangeable eye pieces? That way you could have a 7x for use on a boat and turn it into a 10x for bird watching or checkning out chicks on the beach. Seems like a good idea to me at least.

I don't know of any binocular with interchangeable eyepieces. A much better idea is a zoom binocular. Look at what Orion has. Put "Orion" into your browser. I looked, and the more expensive model sells for about $140 and has magnification 8X to 20X.

This is lot better that fumbling around with eyepieces in a wet and sandy place.

I know a binocular that has interchangable eye pieces, it's called a binocular microscope, :D .

Both Zeiss Wetzlar and Nikon make fantastic binoculars, with zooming capabilities. Zeiss' binoculars are tough. They look as tough as a mag light.

Orion has a cute little erect image 90mm maksutov-cassegrain that can be used either as a spotting scope or astronomical telescope that might suit the purpose (they even make a table-top azimuth mount for it that can be electrically driven and it can also be used as a telephoto lens with an adaptor). It takes standard 1.25" eyepieces, including a zoom. They also sell a variety of spotting scopes, some of which take interchangable lens and/or zoom.

Keep in mind that 10x is hard work to hold still enough for decent viewing for long periods whether you're ashore or afloat.

That's funny you guys mention Orion. I was looking at Orion and am torn between a 10x and 7x, that's when I thought it would be nice if the eyepieces could be interchanged. I was trying to avoid zooms because they are supposed to have inferior optics. What I need is a local dealer so I can go look myself. Wassa - I thought vision could be corrected for by the focus knob? (except astigmatism)

I guess this isn't any answer to the question but I wanted to praise a set of binoculars I recently used. They were some Leica 8x25? micros...and some of the best I've ever had in my hands. I wear glasses and most of the fold-down cups are a real PIA but these worked perfectly and I could actually see out of the binos without removing my specs. The lens quality and clarity was exceptional. One of my pals picked them up at a salvage store....they were the only pair there or else I'd be owning some. Kinda pricey even at this salvage store but worth the $$$$$. Riley

Peter, there was a thread on this topic several months ago. I related how I had bought a pair of Tasco 8X21 for $19.95 plus tax, and I was surprised at how good they were. My opinion is worth something. I am a retired (almost) optical engineer.

No, they were not Steiners, but I cannot justify to myself a pair of Steiners.

If you buy a pair of Tascos for $19.95 and you don't like them you can THROW them overboard and not feel bad. The only fault I could find was the short eye relief, which can be a problem if you wear glasses.

Hey ahp, do you know what are the factors that affect field of view? I know the higher the power the smaller the field but does the ojective lens have anything to do with it? The reason I ask is that I see for example some 8X35 with a larger field of view than some 7x50s, without being "wide field" models.

Casem, for a given eyepiece, the longer the focal length of the objective, the higher the power and the smaller the FOV.

With a given objective, both power and FOV will be effected by the eyepiece design. Power or Magnification = Objective FL/Eyepiece FL. FOV will vary inversly as the magnification for a given eyepiece design.

HOWEVER, there are many eyepiece designs. The less expensive ones have only a few elements (individual lenses) in them. The apparent eyepiece FOV and the binocular FOV will be limited by a field stop.

For any eyepiece, and objective, as you go off-axis, the aberations (coma, astigmatism, lateral chromatism) grow rapidly. One purpose of the field stop is to limit the FOV to a value where the aberations are not especially noticable.

More expensive eyepieces have more more elements and the aberations are acceptable over a larger field. They still have a field stop, but it is larger and allows for a larger field. You get what you pay for.

A mild twist: I had been lusting after the Orion "Eagle Eye" 8x32 monocular for years - recently it was on sale for $40 off, so I jumped on it. Basically it's one half of a roof prism binocular.

One thing not mentioned that separates the cheapos from the quality binoculars is coatings. These range from none, to front and back outer optics coated, to all air/glass surfaces coated. Another factor is whether they're sigle coatings or multiple coatings. No coatings is the cheapest, while "fully multi-coated" are the best/most expensive. Generally, the coatings help with reflections, possibly with color correction and I'm not sure what else, if anything. Maybe ahp can comment...

Anyway, the Eagle Eye monocular is fully multicoated with the higher quality BAK-4 glass prism and it's really slick. Nice and light but a fairly decent light bucket. It's all the quality at 1/3 the price of a binocular with the same specs.

If I was going to buy a full sized binocular, I would/will buy Orion's "Savannah" nitrogon purged, o-ring sealed, waterproof, fully multi-coated roof prism binoculars, the 8x42's especially. They're also "phase coated" (I think the more correct term is "phase compensated", but I'm not sure) which I guess is the next level of coatings beyond multi-coated. I suspect they're a v. high quality OEM product.

As a casual asside, adendum, codicil if you will, we had binoculars in the navy called "LONG EYES". They were mounted on the railing usually, but could be hand held. I think Zeiss made them, thing is they had a focal length of about 14"(500mm). They were astounding glasses and I think are still in use by several navies. I know you could see into the next century with them!!!!!

When I mentioned the Zeiss Weztlar range, they are the Leica lenses. The range of lenses are high in image contrast, similar to those used for Leica's camera lenses. That is what gives a Leica an aparently, higher quality image, with good edge definition, ... it's the lens contrast.

I have Nikons. Not as contrasty as the Leicas. Optically they are very good, but the outer plastic shell is/feels flimsy. The optics have remained in alignment. They are a light weight, hand held binocular. My Nikons are not zooms.

Nikon have a fine binocular, ..site..site..

Don't overlook Leupold Wind River binocs. Waterproof ( I assume they're gonna be on a boat?), and priced right. 8x42 $170 or so. You're gonna pay that for quality binocs. I like them enough to have purchased 3 pairs. Redfield recently reintroduced binocs to their line. My old 10x50 waterproof pair purchased in 86 are still very excellent. I hate cheap binoculars. We use ours throughout deer season and I highly recommend the Leupold. I haven't heard any feedback on the new glass by Redfield.

I bought a pair of Zeiss rubber armoured 7 x 50's in 1985 and they have lived on the boat, winter and summer, ever since. The rubber fold down eyepieces for spectacles need replacement and the mild steel buckle on the strap has rusted through. Otherwise they are fine - I really should have them overhauled one of these decades.

They cost a small fortune but....depreciated over "x" years and allowing for the superb optical quality, it has proven worth while.

Before making this fairly colossal (for me) investment, I used to get through cheap pairs regularly.

At home we have a pair of ex-RN WW2 Barr and Stroud 7 x 50's, as seen in all the best British war films, which are kept ashore for bird watching as their case is less robust than the Zeiss pair, but considering their age their optical quality is astounding. They have actually been serviced (once).

Before making this fairly colossal (for me) investment, I used to get through cheap pairs regularly.

At home we have a pair of ex-RN WW2 Barr and Stroud 7 x 50's, as seen in all the best British war films, which are kept ashore for bird watching as their case is less robust than the Zeiss pair, but considering their age their optical quality is astounding. They have actually been serviced (once).

I bought a pair of Zeiss rubber armoured 7 x 50's in 1985 and they have lived on the boat, winter and summer, ever since. The rubber fold down eyepieces for spectacles need replacement and the mild steel buckle on the strap has rusted through. Otherwise they are fine - I really should have them overhauled one of these decades.

Wow those binocuolar telescopes are wild. And I bet they have interchangeable eye peices.

I ended up getting a pair of Orion 7x50 Vistas for $200. They are really nice. They are not waterproof nor do they look especially durable but they are nice and light and the image is superb. (I was playing with them last night and could easily see moons around Jupiter which is something I've never been able to do with binoculars before.) When I bought them, I figured I would use my old pair for the boat but now that I have new ones I realize just how cheap the old ones are. So I'll probably buy a third pair before too long.

Stan, my brother and I just got a spotting scope as a house warming gift for a friend not too long ago which I think is a Leupold (not sure though; my brother bought it). I haven't had a chance to look through it yet but I hear it's nice.

Okay, so how about some polarized filters for binoculars? I figure that would help when looking for fish or rocks. And I know my 7x50s could use some filtering during the daytime.

Funnily enough, the aforesaid WW2 Barr and Strouds, sixty years old, have polarising filters which can be switched in or out at the click of a switch. Nice feature, and since they were used for constantly sweeping the North Atlantic from the open bridge of a small warship, trying to spot a fleeting U-boat periscope, a valuable one.
