Camera lenses attach to the front of camera bodies and focus what you are taking a photo of onto the camera sensor. You can get lenses with different focal lengths, maximum and minimum apertures, and varying sizes, weights, and quality. I will explain all these in this episode and tell you what lenses I use.

Oh yes - you can get cameras with the lens physically attached to the camera - I am not talking about those. Although most of what I talk about here applies.
