Sigma 50mm f/1.4 EX DG HSM Lens

Sigma 50mm f:1.4 EX DG HSM

Product Summary

Overview

This prime from Sigma is one of the best f/1.4 primes in the business. Designed for full frame DSLRs the lens is compatible on APS-C crop sensor based DSLRs as well with a crop factor of 1.5x. With a fast aperture of f/1.4 the lens is ideal for shooting in low light conditions using a standard shutter speed suitable for hand holding. Bigger apertures are ideal when it comes to creating a soft background blur and the Sigma 50mm f/1.4 EX DG HSM is suitable for that as well. This is a ideal lens for street photography for a “standard view” on full frame DSLRs. For APS-C users the lens has a focal length (due to crop) of 75mm and thus satisfies the needs of a portrait lens.

But these almost clichéd features are not what the 50mm f/1.4 prime from Sigma is known for. The lens has HSM (hyper sonic motor) technology which means it is very quiet during auto-focusing. Additionally it has full-time manual focusing or focusing override which allows the user to switch to auto-focusing to manual just turning the focusing ring.

Look closely and the lens appears bulky and the benefit of it is when you shoot at wide apertures there are no vignetting something that plagues wide apertures and full frame DSLR combinations.

Specifications of the lens are it has 8 elements arranged in 6 groups, a 9 rounded blade diaphragm and external dimensions of 3.3” x 2.7”. The lens weighs a reasonable 505 grams. Similar products: Sigma 35mm F1.4 DG HSM | Sigma 85mm f/1.4 EX DG HSM
