I can't use them. I wanted a 10x pair for the car. My regular Fuji 10x70 are too heavy and unwieldy for this task. I've played around with focus, diopter, and intraocular adjustments for a long time, and there *no* nice place for me. Even when I'm standing still in a quiet place with the "best" setting I can, I spend about 10% of my time taking a binocular picture. Even so, edge distortion and blackout are significant. Opening or closing the eyecup extensions (which are low-friction and too easy to open or close) doesn't help the very picky eye relief of these optics. it's off [on] as a gift, I have unusable binoculars. I do not recommend.
