I will be using a Canon DSLR for a video project and I need an external EVF that will work well with my eyeglasses. The two I'm considering at the moment are the
Gratical and the SmallHD Sidefinder. Anyone have experience using either with eyeglasses?
While I haven't used either of these viewfinders, I can say that I've never had an issue wearing my glasses when using an electronic viewfinder. And I mean looking through the eyepiece not using the little screen as a monitor.
That said, from my extensive experience as a motion picture camera operator, I've found that it's best to use the eyepiece, and not a small monitor as your viewfinder. I find that when one's body is connected to the camera via the eyepiece, one's reaction time and accuracy is increased significantly.
One other thing to watch for with all electronic cinema cameras and viewfinders is viewfinder lag, where the viewfinder is a number of frames behind the action. When the lag is significant, operating the camera will suffer as the subject changes direction or stops before you see it in the finder. I have found this to be the case with some of the BlackMagic cameras using their own supplied viewfinder. So, whatever viewfinder you choose, test it right away to see if you can live with it's delay as there is always some... The delay could come from the camera itself, or from the finder. Which is the cause, I don't really know.
