The Sigma 30mm 1.4 is a large aperture lens that provides a standard angle most similar to the human eye. The 30mm focal length translates to approximately 50mm in 35mm format. Sigma’s 30mm lens is for cropped cameras only and has a minimum focusing distance from 15.7 inches to infinity. This lens creates very sharp images with high contrast and can perform superbly in a great range of applications, including snapshots, portrait, indoor shooting and landscape photography. Sigma’s 30mm 1.4 lens has both auto and manual focusing capabilities which make this lens ideal for photographers.
Rokinon’s 35mm 1.4 Wide-Angle Lens will work on a full-frame camera, where the Sigma 30mm will not. This lens is excellent for portraits and general photography but since there is no auto focus capabilities, this lens is better suited for videographers. The 35mm lens focuses in as close as 12 inches from the lens, and comes with a removable petal lens hood. And again, Rokinon’s 35mm lens is manual focus only.

You may experience some inconsistencies in your image exposure when capturing still photos with the Rokinon as we found out in our side by side comparison. When keeping our ISO and shutter speed fixed and only changing the aperture, the Rokinon’s images were inconsistent. All things considered though, for the price point, the Rokinon is a stand up lens, especially for videographers. This is just another case of you get what you pay for. Either way, no losers here.DSLR, lens comparison, lenses, photography, Rokinon, Rokinon 35mm f/1.4, Sigma, Sigma 30mm f/1.4, videography, wide angle lens
