Macro extension bellows are used mainly for macro photography. The bellows function as an infinitely adjustable extension tube. By moving the lens further away from the body it reduces the focal distance and increases magnification.
These bellows are a manual connection only they have no electrical contacts or circuitry and so focusing and exposure need to be adjusted manually.
You may consider using an old enlarging lens as a macro lens these are corrected for short working distances, contact us for adaptors.
