As popular as the Canon 5D Mark III has been, there are only a handful of LCD ViewFinders made specifically for the camera. If you're an owner, this might be something you've looked into. So here's a look at Varavon's latest MultiFinder UNI / LCD View Finder. There are older versions of the Multifinder that are very specific to each camera, but the new UNI (i'm guessing for universal) has adjustments on the base and on the View Finder itself which allow it to work with a wider range of camera bodies. Below is an unboxing video that i've done and how it fits on the Canon 5D Mark III camera body.
The unique feature on the Varavon Multifinder products is it's ability to achieve low angle shots by use of specially aligned mirrors. The optics can be removed if you only need to use it as a simple sunshade, and the quick release system makes it easy to remove the entire view finder. The MultiFinder UNI
runs for $295 is currently on sale for the holidays at $236 at their website (click here)
