A 35mm lens with a wide maximum aperture is highly versatile, useful for everything from portraits to landscapes, astrophotography, and more. Such lenses can easily run north of $2,000, which, at $799, is what makes Samyang's 35mm f/1.4 AF II quite the attractive option. This excellent video review takes a look at the lens and the sort of performance and image quality you can expect from it in practice.
