External camera screens, also known as field monitors and recorders,
give you a big picture view so you can sort out minor issues before it’s
too late to re-shoot. Of course, most modern mirrorless and DSLRs
cameras offer built-in screens to view and compose your image. But at 3
inches as an unclaimed standard across the industry, most of the screens
are lackluster in their viewing experience.https://buff.ly/3q8zxAc
