Optimizing the Lens?
Hello thegadge, Welcome to the Forum!
I believe you're on the right track; Practice with the camera, try shooting in a variety of lighting conditions and angles, zoom settings, etc. Find out what works and what doesn't. In other words, practice, practice!
You might want to download a free processing program like Picasa, Fastone or Gimp, if you don't already have one. I happen to prefer Lightroom best, but it's not close to free! Seeing your work on a good monitor will improve the learning curve greatly.
One thing that may help, is to understand ALL lenses have what's called a 'sweet spot'. A range in the f/stops where they deliver the highest resolution, best sharpness and least abberations. It varies from lens to lens, but generally is one, 1-1/2 to 2 stops down from maximum aperture.
What that translates to on your 18-55mm zoom is, at 18-24mm (roughly) your best f/stop settings would be f/5.0 to f/6.3
In the 30-40mm length, try f/6.3 to f/8.0. Above 45mm, use f/8.0 to f/9.5. These are about one to 1-1/2 stops down.
Also, try not to go above f/11. There is a different aberration that happens at higher (minimum) apertures, called diffraction, at extremely high f-stops.
What you're doing is using the lens at its strongest points and avoiding the weak areas. This is true, to a greater or lesser degree, of all lenses.
Same thing with shutter speeds. Don't go below 1/100s under any conditions, hand-held. Camera shake and/or subject motion has ruined more shots than practically any other factor and is especially true when you're starting out.
Sometimes you will have to sacrifice ISO (use a higher setting) to achieve these f/stop and shutter speeds. A trade-off, but a necessary one.
All equipment has pros and cons. Knowing what they are and using them to your advantage is simply good management!
