500 EL/M Loose lens - Newb ALERT!

I am so glad that bdial was able to help you work out the problem. All of us need help one time or another.

As others have said, GET THE MANUAL, AND READ IT, with the camera in front of you, so you can follow the manual.
There area few things that may bite you if you don't pay attention.
And the last thing you want to do is to damage the camera or lens from doing something that you should not do.
