How can I adjust focus?


Turn the grey ring around the lens (where the light comes from) until the image is sharp.

I cant get an image or focus


Put the eyepiece with the largest number written on it into the focuser. DO NOT USE the 2 x barlow if you have one. Go outside during the day time and practice focusing on a distant object, by turning the knob on the focuser in both directions until you see a sharp image.

My FM10 focus screen does not focus, but split image works


I have seen bent mirrors and mis-aligned focus screens do this. It is possible for the film plane to be in focus while the viewfinder is out. you can test this with newspaper and a tape measure. buy a cheap roll of neg film and set up your camera on a tripod at a fixed distance, say 6ft. from the paper. Ideally I'd attach the paper to a light stand or the back of a chair. so that the paper is at 6ft, the back wall is at maybe 10ft. and there's something in the foreground in case its front focusing. then set the lens at what the scale says is 6ft regardless of what the viewfinder looks like. Shoot one frame with an aperture of f/2.8 on your 50mm. Shoot a second frame at f/16. rewind the film & develop it at a drug store or 1hr lab. if both images are sharp, the problem is in the mirror/ prism. if the 2.8 is OOF it's the mounting ring. I want you to shoot the F/16 to prove that the stop down lever is functioning.

I have a DSC T70. Sometimes i get a message "File Error" for some of the pictures. For these pictures, the file does not show and when printed, the picture is merged with another picture.


The LCD screen of the Camera may display a FILE ERROR message when trying to view a still image on the Camera if the image was rotated, modified and overwritten using editing software on a Computer.

To play images you have taken on the Camera, it is recommended that you do not make any changes to the original image files.

Pentax k1000 ....lens will not focus...(one 50mm...other 70-210mm)...happened once before...brought to camera store and of course it focused...nothing wrong...took some pics and worked ok...now not...


Try this first.

Set your lens focus to infinity and focus your screen at a far away object (like a distant lampost). If it,s not in focus, then you have a misaligned mirror. Adjust your mirror so that a infinity setting, the split-screen image merge well to form a well focussed image. Hope that helps.

How to focus my Zeiss 10x40B TP binoculars


Your binoculars are known as the Zeiss Classic or what was once known as the Dialyt. They focus differently from the usual binoculars like those mentioned. The rear wheel is to focus both binocular barrels while using them. The front focus wheel is adjust the right eyepiece to suit your right eye. Binocular manufacturers take into account each eye is slightly different. To focus the Dialyt...First close your right eye and turn the rear wheel until the image is sharp in the left barrel. Leave the focus wheel alone. Now close left eye and adjust the front wheel until the image is sharp for your right eye. The image should now be clear and in focus for both eyes. It should not be needed to use the front wheel from now on. The rear wheel is what you will use to change the focus from near to far objects.

My ge easycam is all fuzzy and i caant seem to focus it


If you mean you tried the sharpness setting in the driver it will not help if the image is out of focus.

On many webcams there is a focus ring around the lens, try turning that to get a focus setting that gives a sharp image at the distance you use. If the product pic shown with your question represents your cam, it looks like it has such a focus ring.

Good luck!

Samsung rear projection tv has multiple images with differnet colors


The auto self focus screws up if the picture does not remain constant or close to it while focusing. It is designed to self focus every fifteen minutes. Go to menu and then setup and turn the auto focus feature off. I have had mine off for the past year and have had no problems. If you slide the bottom portion of the remote down you will see a self focus button. My suggestion is to put a DVD in and hit the pause button during a scene and then hit the self focus button. It should align back up and may take a couple of tries. (If you have an aftermarket remote, just enter the menu and then setup and you can activate the self focus feature, just don't turn it to auto focus!)

Black dot.


Ensure focusing is spot on. if your image is a black dot surrounded by white light (like a doughnut) then your not in focus. Look at making a Hartmann Mask (really easy, just google for it), which fits over the front lens. It has 2 or more holes in it,this means when you look through the eye piece you will see double images, adjust focus until the images merge into one (if the images go further apart turn the focuser the other way), when they are merged remove the mask and presto you should be in optimum focus. Always remember telescopes are very sensitive and focussing requires delicate adjustments.

D50 After autofocusing stops it still isn't quite in focus.


Your diopter may not be adjusted ( adjustment for sharpness of image in viewfinder on the side of the eye-piece ) so set that first and then try again. If this is correct then your camera is focusing accurately ( on the sensor ) but only the image in viewfinder looks unsharp.
