Sigma has some unusual addition to the APS-C lens lineup. A 12 mm f/1.4 ultra wide angle lens opens creative options that you don’t usually find on this focal length, especially if you want to work in low light or use it with depth of the area. This means more flexibility that you are shooting for landscape, inner or night sky.
Coming from you Christopher frostThis detailed video covers Sigma 12 mm f/1.4 DC contemporary lensIt is a compact, light prime designed specifically for APS-C cameras, which are Mount for Sony E, Fujifilm X and Canon RF system. What it is. It stands out. Unusually bright f/1.4 aperture is paired with such a wide area. This combination is not common, which means that you can still collect a large amount of light by capturing the huge scenes. For astrophotography, in particular, the ability to shoot at f/1.4 with this perspective is a great thing.
Frost explains that the 12 mm focal length translates about 18 mm of full frame, which hits the sweet space: Ultra wide in the area without crossing the area that feels distorted or difficult. With the aperture wide open, you can blur the background in a way that is rare for this type of lens. That close focusing distance lets you play with a perspective, drawing the environment behind it draws a subject closer. He also shows how it doubles as a practical Vlogging lens, its sharpness, compact build and the kind of subject separation you generally expect from long focal length.

The build quality is solid to its price point. The lens is light at just 250 grams, uses plastic in its design, but still contains dust and splash resistance with the weather-sealing gasket on the mount. The autofocus is quick and almost silent, and an aperture ring with clicked stops, although on the RF Mount version, it acts as a adaptable control ring instead. The absence of image stabilization is not important in this focal length, but you will rely on the stabilization of your camera if you need it.
Image quality is where this lens is really surprised. Wide open at F/1.4, it is sharp in the center with good contrast, and stopping F/2 improves sharpness in the frame. Corners quickly bright and speed up by f/2.8. Deformation and vigning are worth noting without reforms, but with in-camera or raw adjustment, they are well managed. Frost explains that coma and chromatic abscesses are widely open, but when you are closed, it is better if you know that it is a practical option for Starcapes, then you know how to work around its boundaries.
