The OptiView 250 3.2" LCD Viewfinder is used to magnify your camera's display by 300%.
This viewfinder is compatible with most 3.0" and 3.2" displays with either 3:2 or 4:3 aspect ratios. It also blocks light from hitting the screen, ensuring crisp, clear viewing even on bright days.
For enhanced operation, it features a quick-release plate with a 1/4"-20 screw for mounting to the camera along with an interchangeable and adjustable rail system to dial in compatibility with your camera.
The short rail works with most cameras, while the included long rail enables use with cameras featuring battery grips.
Includes a soft eyecup that can be used with your left or right eye, as well as eyeglasses, and the ability to adjust the diopter from ±1.5.
A latch on the viewfinder allows you to quickly flip up the rear half. Additionally, the quick release plate also features six 1/4"-20 threads for use with tripods or other rigs.
