Welcome to Part 1 of a three-part series that lays out the basics of lenses for novices and those who could use a refresher. In this part of the Lens Primer, Larry Becker, of Kelby Media, explores concepts such as aperture, image stabilization (IS) or vibration reduction (VR), and telephoto zoom lenses versus primes.
This final part of our three-part series on lens basics focuses on special lenses: tilt-shift models, which bend perspective and can even generate a "miniature" effect, and macro lenses, including macro rails that can help you create a super-close-up image that's completely in focus.
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.)
