Well-suited for extreme close-up shooting, this Macro Bellows from Fotodiox is designed for Sony E-mount cameras and lenses. This bellows has an adjustable 1.6-5.9" extension range, and is used to increase a lens's maximum magnification up to 8:1 for macro applications. A rack and pinion gear is used for smoothly adjusting the extension amount and a printed scale in millimeters helps to ensure consistent, repeatable settings. An integrated thumbscrew also lets you lock your position in place and suits working with heavier equipment or when shooting at a steep angle. The bellows frame is constructed from anodized aluminum-alloy and there is also an integrated 1/4"-20 socket for attaching directly to a tripod or quick release plate.
