Are lens manufacturers having to spend too much time addressing breathing when it might not matter?
publisher David Etchells, and Yamaki says that YouTube reviewers might be putting too much emphasis on lens breathing, which could take away development time and emphasis from other important lens manufacturing endeavors.
“So we know the professional cinematographers. And of course focus breathing is very important for that, and also parfocal designs. But there is no perfect lens. So I know that professional photographers or cinematographers can deal with a lens with some breathing or that isn’t perfectly parfocal. They know how to use it.
“It’s a little unfortunate that online video reviews of lenses have called so much attention to the issue when lens designers might be able to achieve better overall performance if they weren’t forced to place so much emphasis on insignificant levels of focus breathing,” Etchells comments.
