When it comes to camera lenses, tilt-shifts are a bit of an odd variety that can be intimidating when you first come upon them. This helpful video will introduce you to tilt-shift lenses, how they work, and why they're a great tool for many photographers.
Coming to you from Canon USA, this great video talks about tilt-shift lenses and why they're treasured by many photographers. Tilt-shifts are definitely in their own category, as they're all manual focus only, and the plethora of knobs and dials can make them a bit difficult to grow accustomed to. Nonetheless, those controls serve very useful purposes, such as allowing you to control the focal plane or correct nonparallel lines. Architecture photographers swear by them, but their usefulness extends far beyond that genre. By tilting the focal plane, you can keep more in focus while using a wider aperture to let more light in, or you can selectively focus on different elements of a scene. Most tilt-shift lenses are also remarkably sharp, and they make excellent portraiture lenses. My favorite combination at the moment is the older model of the Canon TS-E 90mm f/2.8 with the Sony a7R III. Give the video above a watch for more.
