In case you were ever wondering how many of our smallest lens equal one of our biggest lenses, and how our lenses size up to a cardinal or a 16 oz cup of coffee, we present the Holiday Season 2013 Sigma Lens Comparison Chart! Here’s our entire lens lineup, to scale.
Prime lenses are designed for exceptional imaging at a single focal length. Unlike zoom lenses that easily span a given focal range and variable field of view with a twist of the zoom ring, the field of view and focal length remains constant. If you want to take in less of the surroundings with a given prime lens, you’ve got to physically move closer, and to take in more of the scene, you’ve got to back up. But of course, as you move, the angle of view remains the same all the while.
This week’s Fan Photo of the Week was made by Tim Drivas with the Sigma 15mm F2.8 EX DG HSM Fisheye lens on a Canon 5D Mark II.
