SOURCE: double vision

The distance between the centers of the eyepieces of your binocular must be the same as the distance between your pupils. This distance is adjusted as follows: 1. Focus on a distant object. 2. Pivot the two halves of your binocular farther or closer apart until you can see a single unobstructed, circular field of view. Make sure to focus on a distant object when you do this because when you focus on a close object you always see two slightly overlapping circular fields. Your binocular may have a scale on the top, between the eyepieces, to help you remember this setting.

SOURCE: bushnell insta-focus mechanism gets stuck.

they were famous for that, because the screwpin that holds the eyepice shaft is metal and the groove that it rides in is plastic, and eventually gets jammed....look where you put your fingers to adjust eyepieces. should be small metal plate in center of hinge(sometimes with bushnell logo) that will simply pry off by using small screw driver,and now you will be able to see if the screw is loose or damaged. good luck...larry@reichinstruments.com

SOURCE: is my bushnell insta vision 7x35 or 10x50

The first number is the magnification the second number is the size in millimeters of the objective (large lens) So if you measure the diameter of the front large lens that will give you the size. So a 10x50 means a magnifyng power of 10 and an objective of 50mm.
Now to find out the magnification if you don't know what it is. Measure the front lens. Then if you look through the eyepiece lens while holding it away from you you will see that there is in each a small circle of light. That it what is known as the exit pupil. It lines up with the pupil of your eyes when you have the binoculars pressed up against your eyes. Now measure the diameter of the exit pupil in millimeters. It will only be a small number.

To work out the magnification use this formula. Magnification = Objective size divided by the exit pupil.
So a 10x50 will look like this M = 50 divided by 5....therefore M =10 which is the magnification.

Both the 7x35 and 10x50 will have an exit pupil of 5mm. So if yours is one of these then all you need is the objective (large) lens size.

Return it to Bushnell. There will be no user serviceable parts. I trust the optics are clean, and there is no condensation inside the optics? The unit is no longer in production.

If you had a compact camera it would say 10x zoom what is the equivilent in a 70mm -300mm tamron


A 35-80 mm lens is 2.3X zoom. Divide 80 by 35 and you'll get the result.

It is usually better to know what the focal length of a lens in "35 mm equivalent" is and judge by that, rather than relying on the "X" power of the lens. For instance, most point and shoot cameras start at about 35 mm and have either a 3X or 4X zoom. This would make it a 35-105 or a 35-140. I've seen some that start at 28 mm, though. A 3X starting at 28 mm is 28-84 and a 4X is 28-112. Neither one is a particularly strong telephoto lens and the 4X is just about the same as the 3X that starts out at 35 mm.

It's also important to realize that tradition dictates that lens focal lengths are usually expressed in terms of "35 mm equivalent," where "35 mm" refers to a 35 mm film camera. This is because of the relation between the sensor size and the actual focal length of the lens and the resultant angle of view of the lens.

I have one point & shoot that is actually a 5.8-24 mm zoom. This is a 4X zoom. The 35 mm equivalent is 28-116 mm. The sensor is 7.2x5.3 mm. (1/1.8") (And I wish I knew someone who could explain how the heck they came up with sensor size terminology!)

I have another point & shoot that is actually a 5.7-17.1 mm zoom. This is a 3X zoom. The 35 mm equivalent is 34-102 mm. "How could a shorter focal length give a longer 35 mm equivalent?" you might ask. It's because the sensor is only about 5x4 mm. (1/2.5")

I have a few Nikon DSLR's and - thankfully - they all have the same size sensor. They all have a "lens factor" of 1.5. This means that you just multiply the actual focal length of the lens to get the 35 mm equivalent and then you can make comparisons accurately from camera-to-camera. Most Canon's, for instance, have a lens factor of 1.6. On a Nikon DSLR, a 28 mm lens is the "35 mm equivalent" of a 42 mm lens. On most Canon DSLR's, the same 28 mm lens is the equivalent of a 45 mm lens.

These example are just to show you how freaking confusing it can all become if you try to make sense of the "X" power of a zoom lens.

Bottom line...

Check the 35 mm equivalent specifications for the lens. This way, you will be leveling the field and comparing apples to apples. More or less.

Need information and Instruction Manual for a Vintage Bushnell 300mm camera lens


This is not a zoom lens, it is a fixed focal length of 300mm telephoto, so the focus ring will not slide back and forth, merely rotate. It is also manual focus. If you google it, you may find a manual, but doubtful - best bet is to get a book on basic photography and read up on telephoto lenses there.
Update - allegedly made by Tokina, so should be a reasonable lens.

Loose hinge _ Bushnell small binocs - 8 x 21; 392 FT at 1000 Yds.


Bushnells are inexpensive binoculars. A repair would cost more than a new one. If they are out of alignment to have them collimated would take time and that translates to expense. Its not something that can be done at home without a collimator. New ones similar to yours can be found online for between twenty to forty US dollars. Binoculars today can be bought much cheaper than a few years ago. If you are happy with the use you have had from your Bushnells an update won't break the bank.

Bent


Not likely. These binocs are reviewed elsewhere by many, and appear to be pretty much cheap junk.

I happen to have a pair, and the right lens support that is screwed onto the body is cracked plastic.

Maybe with your set, and mine, we could make one good, functional unit... but when you could buy another (ah ma zon dot c o m) for less than 11 dollars, why bother.

Sorry... but they just aren't really very well made. As to the bent focus mech you have, I doubt you could obtain a part, anywhere, to replace the bent one. You might try to straighten the bent part by careful disassembly of the body, but do know that there's a bunch of glued together parts in these binocs, and not too many parts that can be removed/replaced with screws.

Zoom will not retract


Dear Grammie,

You have either experienced a lens error or your zoom dial is broken (both usually caused by some sort of impact damage, but which can be spontaneously occuring).

Look for an error message on your camera's LCD screen such as "E18," or "lens error restart camera." If you do not see a lens error but simply cannot retract your zom lens (go into wide angle mode) via the zoom lever then it simply maybe a broken command dial. Either way, however, you will need to have the camera serviced in all likelihood. Call tech support at 1-800-828-4040 M-F from 8 am to 12 midnight EST and Saturdays until 8 pm EST. Hope this helps.

Sincerely,
