Hi there,
It seems as if the lens isn't installed properly, make sure it's screwed in right in its mount.

Good luck!
Tom

Nikon EM (1979?) When I zoom out with my lens, the picture in the viewfinder is very blurry.


What happens when you turn the focus ring? And just out of curiosity, how are you getting to a 30mm setting on a 35-105mm lens?

My kodak m1033 camera won't focus, it tries to, and I can hear like gears moving while it tries to focus, but nothing- still blurry


You don't say anything about light conditions, target color, definition, contrast, and the many other things that can cause this.

Is your camera at fault? Maybe.

Problem with my Olympus FE-230


When I turn my camera on, the lens goes in and out a few times. Once it's finally on and I look at the screen, everything is blurry. When I take the picture, it's blurry too. If I try to use the zoom to adjust, the lens starts going in and out all crazy and won't adjust right.

I can turn my camera on then the screen picture is all blurry and it won't do anything if you press the button as if to take the picture. The one thing i have noticed different is the letters [CAF] in the...


When the camera is set to C-AF (Continuous Auto Focus) mode the focus is continually aligned according to movement of subject or the camera even when shutter button is not pressed. The Continuous Auto Focus (C-AF) is disabled while the camera is zooming in and out. Once the camera stops zooming the CAF is initiated and the cameras focus is adjusted.
This is actually used for video.
