Adding either of these Sigma 50mm F1.4s camera lenses to your kit is a great idea. Is the Sigma 50mm F1.4 DG HSM | A or 50mm F1.4 EC DG HSM right for you?
There is one question that is asked of me most often when I am teaching photography. That question is “Which lens is your favorite”? That’s such a terribly difficult question for me to answer. Lenses are like children, I love them all and hate to play favorites.
All kidding aside, I carry 5 lenses with me everywhere I go. Sigma’s 35mm F1.4, 50mm F1.4, 85mm F1.4, 24-70mm F2.8 and the 70-200mm F2.8. Most of my boudoir shoots are done in studio. My studio is very small (about 10’x10’) so I most often shoot with my 50mm due to size constraints. What if I want to take my client out to the rooftop though? (I’m bringing out the 70-200mm for that!) or into the vestibule (only the 24-70mm will do there). I would be unprepared without the other lenses.
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.
