Canon DSLR Dual Image Viewfinder

Canon DSLR Dual Viewfinder

A pair of recently published Canon patents reveal a new viewfinder system for Canon DSLRs that will allow photographers to “chimp” their shots without ever taking their eye off the viewfinder.  The patent applications filed in the United States Patent and Trademark Office (“USPTO”) under application numbers 12/495,813 and 12/495,814 were each filed on July 1, 2009 and published by the USPTO on January 7, 2010.

The essence of the technology claimed under the patents is an advanced viewfinder system that uses a small backlit LCD or OLED inside of the finder to project previously captured images onto a mirror in the pentaprism, which in turn, is reflected toward the eye of the photographer.  As a result, the photographer sees two images in the viewfinder – the live optical image and the previously-captured image from the LCD.

The purpose of this invention, as stated in the patent, is to help the photographer be more efficient by keeping his or her eye in the viewfinder and not having to pull away from the action in order to check exposure, white balance, focus and so on. [Read more…]

The technological advancements found in the D3 and D300 have pushed Nikon to the forefront of the DSLR market.  According to recently published patent applications, Nikon may have something special up its sleeve for its next generation of DSLRs. [Read more…]
