DSLR Lens Primer, Part 2


In this second part of our three-part primer on DSLR lenses, Larry Becker, of Kelby Media, discusses basic concepts such as autofocus, filters, and what various sensor sizes mean for the lenses with which you might pair them. (If you've ever wondered what "crop factor" means, this video clears that up.)

Other topics include filters (UV, polarizing, neutral density), lens coatings, and lens challenges such as chromatic aberration and barrel distortion.
