50mm and 85mm Prime Lenses

If I’m going to shoot portrait photography, two prime lenses are coming with me: the 50mm and the 85mm. The 50mm lens is also know as the “nifty fifty” and it can be easily found in many photographers bags. The reason why.. is because it offers incredible versatility with a perspective that is very close to what our eyes see. A 50mm focal length is definitely what I would choose if I want to capture a subject while maintaining a good sense of context. With low aperture, a nifty fifty will also deliver a pleasant background blur.

Because the flattering compression and the beautiful dreamy bokeh, I find the 85mm a very elegant lens. Another strong point in favor of this focal length is the ability to isolate the subject from the backdrop producing an artistic effect.

As a Canon DSLR photographer, I’ve experienced both prime and zoom lenses, with a various workflow, one choice doesn’t exclude the others. Prime or fixed lenses have the edge over zoom when shooting in low-light conditions, in fact they are still able to deliver sharp images at wide open apertures.
