Why does autofocus keeps moving in and out on some slides


The autofocus system isn't really "autofocus". It is a measuring system - you manually focus the first slide, which sets the distance from the front of the slide in the gate to the back of the projection lens. By the focus motor moving the projection lens, subsequent slides will maintain that same distance. Continuous focus adjustment suggests that:
1> The curvature of the slide is changing because of the varying heat absorption rate of the transparency.
2> The autofocus system is out of calibration.
3> The autofocus system has a bind (it is being restricted from free operation).
About the only thing a user can do is to make sure ALL slides are oriented the same way in the tray. Beyond that, you will need a service manual and 2 or 3 specialized tools. Parts and tools can be purchased from: www.micro-tools.com

Chords needed for elmo 400af


You are a teacher, and you don't know the difference between a chord and a cord ? Amazing. I think anyway you mean a lead - the one you require has a plug on one end to fit the projector, and a plug on the other to fit the camera. Look in the respective manuals.

Why wont my Nikon af nikkor 70-300mm G lens autofocus its self with my D5000 camera


The D5000 does not have a focus motor in the body, relying on the lens to have one. The old 70-300mm G lens does not have a focus motor, relying on the camera to have one. Thus, this combination will not autofocus.
The newer 70-300mm AF-S G lens, as well as the even newer 70-300mm VR AF-S lens, do have the autofocus motor and thus will autofocus on the D5000.

I have a weird problem. When i put the 50mm 1.8 on my D90 it continues to autofocus even when I switch the camera body to M mode instead of AF with the switch. I would like to be able to manually focus...


You probably have a problem with the A/M switch on the body-- flipping that switch should extend or contract the autofocus pin that drives the lens. This particular lens doesn't have its own focus motor, so there's no way that it could be focusing on its own without the pin from the body driving it.

Try taking the lens off of the camera and looking at the autofocus pin as you flip the switch from auto to manual focus.

Will not take pictures


Does your lens try to focus or it doesn't try at all? You will have to understand that for the camera to autofocus successfully, theere should be adequate light and contrast. That means, autofocus often fail to focus even colored walls or objects under dim light. If you tried all this in daylight, outdoors, then the autofocus sensor is faulty. Please reply with details of how you tried the af.

Focus malfunction


THere is a little switch on the back of the camera, just under the area selection Dpad. Make sure it is not in the 'L' setting. This locks the selected autofocus area.
