Kapkur Viewfinder for Canon EOS DSLR Camera

With the convergence of DSLR filmmaking, there are many essential tools that are needed to get the correct form factor for video. When shooting video on a DSLR camera, you must use the LCD screen and you must use manual focus. The combination of a very small screen, manual focus, and razor thin shallow depth-of-field makes it very challenging to focus. When shooting in both outdoor and indoor settings, the sunlight and glares make it nearly impossible to see the LCD screen. Lastly, holding the camera out in front of you so that you can focus on the screen makes the camera unstable and shaky. With any camera, you want to bring it close to the body for stability.The first essential item to help with these challenges is a DSLR Optical Viewfinder.

In photography, a viewfinder is what the photographer looks through to compose, and in many cases to focus, the picture. Most viewfinders are separate, and suffer parallax, while the more complex single-lens reflex camera lets the viewfinder use the main optical system
