III.Description
SmallRig 28mm External Optical Viewfinder 5873 is designed to assist with camera framing while recreating the retro shooting experience of the film era. It provides a more natural optical view and helps reduce color shifts caused by glare or reflections.

The viewfinder mounts to the camera hot shoe via a cold shoe mount and features a built-in silicone pad on the bottom to help protect the hot shoe contacts. It provides a field of view equivalent to a 28mm focal length on a full-frame camera. For APS-C cameras, an 18mm lens is recommended for a matching framing experience.

Its optical system uses five groups of high-quality optical glass with a light transmission rate of up to 98%, delivering a clear, bright image with minimal distortion. Built-in 3:2 frame lines help define the framing area for easier composition.
