Scott and Matt introduce the concepts covered in this class and begin the discussion of why you should move beyond the lens that came with your camera.
The choice of lens focal length has a huge impact on how much of the scene you can include in your photo.
Each lens has a maximum aperture opening, which is expressed in f/stop. The lower the f/stop number the larger the size of the aperture. The larger the aperture the more light can pass through the lens to the sensor.
The size of your sensor is a consideration in choosing your lenses.
After building the foundation for understanding lenses Scott and Matt discuss some of their favorite lenses.
Some lenses are better for capturing landscape scenes than others. Scott and Matt also discuss several accessories for shooting better landscape photos.
There are many considerations when traveling that will affect your choice of what lenses to bring.
When shooting weddings you want a fast lens that allows for shooting in low light and can produce a shallow depth of field to blur out the background.
For most sports photography you will need lenses that can bring distant subjects up close and have large apertures to allow for using action stopping shutter speeds.
There are a few accessories for your lenses that can help improve your shots.
