Quote History Quoted:
I then tried my luck on an ultra close up of a slug that was making its way across a rock. I was using my 55-250mm lens. For some reason when I had the lens zoomed to the max it wouldn't allow me to take the shot. Was this lens the wrong one to use on this particular subject? I wanted to get a picture of this slug, similar to one posted here, of a bee covered in pollen, so I'm not sure what I'm doing wrong there..

The most likely explanation is this: you were too close to the slug (inside the lens' minimum focus distance). Since the lens could not focus, the camera would not take the blurry picture. (You should be able to change the settings to allow out-of-focus pictures.)

Aside from this I also need some schooling on shutter speed and the importance of light position. Thanks again for the information. I will be checking out the above suggested books.
Shutter speed is part of the exposure triangle: ISO, aperture, shutter speed. The ISO governs how much light is needed for the shot; aperture and shutter speed control how you get there: as one goes up, the other goes down. There are pros and cons for adjusting any of these settings; everything is a compromise.
Fast shutter speeds will freeze action. Slower shutter speeds will allow for motion blur (wanted or not). Motion blur can come from both the subject moving or the photographer's unsteady hands, or both.
I have not read it, but the book "Understanding Exposure" is supposed to be a good one.
