Can't seem to find this. I shoot outdoors on the ocean 8 hours a day, 3 days per week and am looking for an eyecup to block out sunlight coming in from the sides, I don't wear glasses (though I sometimes have sunglasses on), and I use my left eye.
I've seen the Hoodman one but it's HUGE, and seems more designed for glasses and the right side of the face, and seems to block a good portion of the viewfinder. There's got to be one that isn't so bulky.
Any suggestions would be very much appreciated!
