Overview
We currently have three different types of lenses for use with the Canon cameras. 100mm Macro, 50mm, and 14mm wide-angle. Each lens works differently and produces an image with different characteristics. Each lens also has settings that will produce optimal quality images.
100mm Macro
Optimal F-stop setting
- f/8.0
50mm
Optimal F-stop setting
- f/5.6
14mm Wide-angle
Optimal F-stop setting
- f/8.0
Examples of F-stop focus blur
- The images below show the chromatic aberration effects of low aperture number f-stop settings on the quality of image focus.
