We’ve been learning little bits about iOS 7. We now know that it adds zooming in video, too. Previously, only photos could be zoomed in on. This isn’t a huge deal as many phones do it, but it’s a welcomed addition for some folks who want to get a closer look when filming.
Personally, digital zooms aren’t great anyway. They tend to pixelate and look terrible. In fact, some of us at iSmashPhone hate photos and videos taken with digital zooms. It’s best to take the photo as is, and zoom in or crop the section you need if you must. At least you still have all the photo information surrounding the image.
Regardless, the option is there.
