This is the Sony 50 F1.2 G-Master lens, along with all the paperwork, trash, plastics, and more trash, and more trash, and more trash, until you finally get to the lens itself. You get a great haptic aperture ring that you can also make silent and smooth if you want, as well as two custom buttons that you can program in the camera, and an auto-focus to manual-focus switch on the side. The glass on a G-Master lens is beyond exquisite, so I immediately cover the front element with the UV filter to protect against dust, moisture, and damage, especially since as a 50mm, this is the perfect all-around prime, and since it's a G-Master, it's always going to be in my back.
