The Ikelite 45-Degree Magnified Optical Viewfinder is designed to position the viewing window farther away from the housing without changing the viewfinder image size. Enjoy a brighter, larger image with less vignetting (dark shadows in the corners of the image) as compared to our standard viewfinder. The 45° Viewfinder provides a totally different shooting experience. Since we are typically in a horizontal position when diving, viewing your frame at an angle reduces arm fatigue and often makes framing easier when your subject is slightly below you and/or tucked into the reef. The 45° Viewfinder rotates to any angle, so its simple to switch between shooting landscape, portrait, or just about anything in between! The included tool makes it easy to remove your housings original viewfinder, and both install and remove the 45° Magnified Viewfinder. We recommend removing the 45° Magnified Viewfinder from the housing for travel. Since no modification of the housing is necessary, the standard viewfinder may be re-installed and your Magnified Viewfinder will transition to your next Ikelite DSLR housing when you upgrade cameras. Note: This viewfinder is designed specifically for use with Ikelite housings.
