SONY Wide-Angle Zoom Lens E 10-18mm F4 OSS Sony E-mount APS-C exclusive SEL1018 This ultra-wide-angle zoom lens, designed exclusively for E-mount, covers an ultra-wide range from 15mm to a wide-angle equivalent of 27mm. The optical system, featuring 3 aspherical lenses and Super ED glass, effectively corrects various aberrations that occur with the ultra-wide 15mm focal length, achieving high-contrast depiction. It can be used at a wide-open aperture of F4 across the entire focal range, allowing for shooting at fast shutter speeds even in scenes with insufficient light, such as dynamic landscapes and evening views. It also incorporates optical image stabilization. The beautiful bokeh created by the circular aperture is also a key feature. There is some dirt due to slight aging, but the performance and operation are good. As it is a zoom lens, there may be some dust inside, but it does not affect the image quality. I believe there are no scratches or mold on the lens.
