Sony K-91780-10 55-210mm E-Mount Lens + Flash Kit

The Sony K-91780-10 kit pairs the Sony Alpha E-Mount 55-210mm f/4.5-6.3 OSS zoom lens with a curated set of accessories designed to extend a photographer's capabilities right out of the box. The lens itself covers a telephoto range equivalent to 82.5-315mm on APS-C Sony bodies, making it a natural choice for sports, wildlife, travel, and event photography where you need to reach distant subjects. Optical SteadyShot stabilization is built into the lens, helping counteract hand shake at the longer focal lengths where even small movements can blur an image. Internal focusing keeps the lens barrel length constant during autofocus operation.

Beyond the lens, the kit includes a Vivitar SF-4000 bounce zoom flash with slave mode capability, paired with a soft box diffuser for spreading and softening the flash output. A 49mm Vivitar 3-Piece Multi-Coated HD Filter Set — including UV, CPL, and ND8 filters — threads directly onto the lens for protection, glare control, and exposure management in bright conditions. Rounding out the bundle, a Precision Design 6-piece cleaning kit and Sony LensPen provide the maintenance tools needed to keep optical surfaces clean in the field. For photographers building out a Sony mirrorless system, this kit delivers a practical combination of reach, lighting, and lens care in a single package.
