Question about Canon L IS WP (10x42) Binocular

1 Answer

Yellow Chromatic Abberation

I just bought a new Canon IS 10x42L. While the images are clear and crisp it does show yellow color on the edge of a subject especially when the subject is contrasted against a blue (like a bird for example) or black sky (Example, watching the moon at night shows a yellow edge on the left end side of the moon, no coloration around the terminator though). Yellow edge on subjcets will diminish when moving the binoculars a little and only shows up when holding the camera still for a few seconds. Engaging the IS makes it worse. What can I do?

Focusing problems

Hello Samaro,

This effect is produced when the tho sides of the binoculars are not focusing the same.
Since you sayit is present at long distance, it might be that one barrel is stuck and is not focusing the same as the otherone when you scroll the middle "focuser".

What you can do is open it up and try to clean it, also see if there is something, that is making one of the lenses not move forward as far as the other one.

Good luck,

My Canon 10x30IS Image stabilized binoculars show a double image. Both sides focus and stabilize. Can I do something to fix it or should I send them in for repair?

Like I said before, one of the prisms has shifted and the binoculars have lost collimation. This is not something you can fix yourself.

I bought these for my husband. In trying them

Difficult to answer specifically without knowing the model. But binoculars are designed to view objects in the distance. They all have a limit as to how close they will focus based on the magnification and design. Objective lenses that are far apart such as on a porro prism binocular will not focus very close. The nature of the design of having the objectives further apart than the eyepieces doesn't allow it. When trying to focus too close the image will appear blurred and double. That is the nature of the design. 9 feet or 3 metres is considered quite close to focus a binocular and is usually for a model designed to do this such as a roof prism where the objective lens and the eye lenses are inline. A specialty binocular such as the Pentax Papilo will close focus to 50 centimeters. It has been designed so that the objective (large lenses) lenses converge.

Take into account when focusing that binoculars are also designed to compensate for differences in each eye. One of the eyepieces either right or left will adjust seperately. For binoculars with a center focus ring. First focus using the center ring with one eye covered. The eye that should be covered is the one that doesn't have the adjusting eyepiece. When the image is clear close the eye you have just used and leave the center focus alone. Focusing on the same spot look through the eyepiece that adjusts and turn the eyepiece ring until the image is clear. Now all you have to do is focus using the center ring only as the binoculars are adjusted for each eye.

Some binoculars do not have a center focus and each eye will adjust seperately.

Dropped new Celestron Skymaster 15x70 binoculars. Nothing appears broken, but now have two images. Can I repair this. and how? Thanks. Dan

Don't "unscrew" the binoculars. there are no user servicable parts inside. the collimnation adj screws are beneath the rubber boot just under where your index fingers rest when looking through the bino's. use a jewelers screwdriver to tease the boot up and stick a small nut or something in. then put the binos on a stable surface and play with the screws a bit while watching the images. you can get them pretty close this way.

I'm trying to figure out what kind/model of cabelas binoculars I have. they are very large, say bak-4 prisms, 20x80 field 2.7

these binoculars were made for astronomy or day viewing but are hard to hold steady by hand, best to use tripod...bak4 prisms means you should get a sharp image from edge to edge, in cheaper models with cheap prisms only the center of the field of view is

Canon 12x36 is binoculars

Your alignment is out in the vertical. There are two prisms on each side and you want to adjust the lower ( on the right side ) prism so that you correct the image in the vertical dimension. Caution : it doesn't follow that just because the image seems to be out on the right hand side that it is the right side that fas to be adjusted. So be prepared to adjust the other side. Also the best is to adjust little bit on each side until alignment comes right.
