quick take // This lens is fantastic, the build feels solid and photos come out sharp. In use the 10mm (16mm equiv.) is perfect for capturing expansive landscapes. I attached a small tripod from Sirui (B&H) and used the lens for selfies and group photos on hiking trips. At 10mm there is a lot of distortion on the edges of these close photos, extending the tripod allowed me do selfies with 14mm to 18mm focal lengths and eliminate most of this distortion. For the real estate shots, this lens was perfect.
