4Sensei DOC-CK Deluxe Optics Care and Cleaning Kit
Complementing the lens itself, the Sony FE 50mm f/1.8 Lens with UV Filter Kit from B&H bundles the normal-length prime with a 49mm UV filter.
Sony FE 50mm f/1.8 Lens
A simple, bright, and lightweight normal prime, the FE 50mm f/1.8 from Sony is a versatile normal-length prime lens designed for full-frame E-mount mirrorless cameras. Its sleek design makes it well-suited for everyday shooting, while the fast f/1.8 maximum aperture benefits working in low-light conditions as well as offers increased control over depth of field for selective focus imagery. The optical design incorporates one aspherical element to control spherical aberrations, an employs a double-gauss configuration in order to realize sharper, clearer image quality throughout the aperture range with reduced field curvature. A DC actuator is also employed to provide quick and precise autofocus performance that is also quiet to suit video recording applications. Additionally, a rounded seven-blade diaphragm is featured to render out-of-focus highlights with a smooth, circular appearance. Characterized by its straight-forward design, this go-to lens balances both ease of handling along with enhanced image quality.
Normal-length 50mm prime lens is designed for full-frame Sony E-mount mirrorless cameras, however, can also be used with APS-C models where it will provide a 75mm equivalent focal length.
Fast f/1.8 maximum aperture benefits working in difficult lighting conditions and also avails greater control over focus placement for working with shallow depth of field techniques.
One aspherical element is incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
Double-gauss optical configuration helps to reduce field curvature and distortions for more consistent image quality from edge-to-edge.
DC actuator motor offers quick, quiet, and accurate autofocus performance to suit both stills and video applications.
Metal bayonet offers increased durability and a solid feel when mounting the lens.
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
Hoya 49mm alpha MC UV Filter
The Hoya 49mm alpha MC UV Filter is a general use, clear filter that helps to absorb ultraviolet light. No additional coloration or contrast is provided, allowing you to pair this filter with others.
The UV filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.
Hoya alpha UV filters are multi-coated for reducing flare, ghosting, and reflections on the filter surface. As a result, a higher light transmission of approximately 96% is possible, providing you with additional contrast and high color fidelity.
The alpha filters are constructed from optical glass and a precision milled aluminum frame.
