Re: one eye or the other seems slightly out of focus.
Hi, one of your eyepieces has an twisty eye piece, its printed on the outside + & -, probably the right side? If its the right side you close your left eye and focus with your right, then open both & HEY Presto, you've got vision in both! Thanks Mark

Oh, neat! Autofocus binoculars, they run off the same lithium batteries used in cameras (just like an autofocus camera, without the film). Minolta got out of the business in 2006, so unfortunately unable to find a manual, but this eBay listing (for a slightly less powerful unit) covers the basics pretty well.
From the listing:
Holding down the large button continuously focuses on the subject. The two smaller buttons are to focus manually. Minimum focus distance is about 6 feet. Eyepiece spacing adjustment is with the sliding bar that has a locking lever on the bottom side. Individual diopter adjustment is with the two sliding bars on the bottom, to match each eye to the autofocus.
The binos will rack focus both at the same distance, you need to rack focus left side to distant image with left eye only, then turn diopter focus to focus right eyepiece. Diopter focus is thinner wheel behind focus wheel
While looking through the viewfinder, turn the diopter adjustment knob just above and right of the viewfinder to adjust it until the focus marks and other information in the viewfinder become sharp to your eye.
Diopter is for your eye only and does not effect the focus of the camera. By using the 1/2 down method, by pressing the photo taking button half way down, you can set the cameras focus. on some cameras this is shown where it will focus by a red square. If you change the diopter this is like adding by focal lenses for reading a book. and setting the distance your particular eye needs for eye relief. On binoculars this is done with screwing the eyepiece closer or farther away from the other lens. check out online http://en.wikipedia.org/wiki/Eyeglass_prescription this will give you more details of what a diopter is or does. Always know what setting your shooting at as well. for instance if you are on a flower setting or Macro then this is for up close work. But up close doesn't mean too close. Most cameras on Macro need to be 6 inches to 12 inches away. But if you are say 24 inches away it won't focus right so don't try to zoom in, use your optical instead of digital and simply move closer or change the settings on the camera to a different setting or it may be blurry.
First you must focus the left eye on a given object with the center focus wheel. Once the left eye is sharp while looking at the same object adjust the right eye to be as sharp as possible. The right eye diopter is only meant to adjust for the small differences between the eyes.

One possibility that you can correct:
The eyepiece (viewfiender) diopter is out of adjustment for your eyesight.
Look at the viewfinder and locate the "slider".
Now look through the eyepiece (viewfinder) while in auto-focus mode.
Adjust the slider, left or right, until the image looks sharp to you.
If you wear corrective glasses, you can adjust the diopter whether you use your glasses or not.
This solution assumes that you are shooting in auto-focus; however, this also works in manual mode.
If you require more info, please post a comment for me, or view other expert advice.
It is common for binoculars to have one independently focusable eyepiece. If one eyepiece can be rotated, then that is the case.
If that is the case, focus through the one that DOES NOT rotate using the center control until you get a sharp image on that side. Then rotate the eyepiece on the blurry side until the blurry side is sharp. If you succeed at this, from henceforth the center control will focus both eyes adequately
first open and close the binoculars untill they fit you eye width,now adjust left eye with the flat section located on the center hinge,now turn right eyepiece till clear. note: once you have adjusted right eyepiece you only have to leave it in that position in order to focus from near and far.........good luck......email@example.com
Use the diopter adjustment to refocus the viewfinder to your eye.
Point the camera at a sign or something with writing on and half press the shutter button to focus then move the little adjuster at the top right of the viewfinder until the image in the veiwfinder is in focus
