Built for sony E-mount APS-C sized camera bodies, the 10-18mm offers its constant f/4 aperture across its zoom range, allowing your exposure to stay the same from wide to zoom. The ultra wide 10mm focal length is perfect for capturing wide landscape and architecture, or make the most out of small spaces. And don’t be afraid to shoot close. It has a .082 ft minimum focusing distance, meaning you can get close to your subject while elongating space behind your subject, making for dramatic perspectives. A 15-27mm full frame equivalent, the 10-18mm f/4 and its optical stabilization chops make for a great walkaround lens.
