DSLR Lens guide. This video teaches how to understand everything about camera lenses, which can be very difficult starting out. Topics covered include zoom lenses, prime lenses, wide angle, mid range, and telephoto lenses. As well as focal length, background compression, bokeh, UV filters, and all the rings, switches, buttons and what they do. Also going over all the letters and numbers and what they mean.
Also here are some links to things I referred to in the video
