SONY 12-24MM F/2.8 GM LENS
Sony describes its new 12-24mm f/2.8 GM lens as the world's widest full-frame constant f/2.8 zoom lens, and they're not kidding. With a lens such as this you can see beyond the scope of the human eye, and with a fast f/2.8 maximum aperture, the lens is also a great candidate for night scenes, Milky Way shooting, and other low-light subjects where avoiding extremely slow shutter speeds are key.
The other main advantage of an ultra wide-angle lens (as opposed to a “traditional” wide-angle such as a 16-35mm) is the creative possibilities it opens up.
