The Fotodiox Pro TLT ROKR adapters allow for a 10mm shift left and right as well as the ability to tilt 10 degrees one way for perspective correction. The shift functionality of the TLT ROKR allows for distortion control and the ability to experiment with creative effects. As well as providing correction for parallax issues, the tilt correction will allow for greater compositional control by allowing the separation of objects within the same plane. This will help to highlight the key items in the composition without the need to rearrange or rethink your setup. Utilizing both tilt and shift provides new levels of technical control.TLT ROKR adapters are designed with precision tolerance that creates a solid, gap free, no play, no wiggle connection with no adjustments needed. Precision all-metal construction with chrome plated brass mounts for a secure and solid fit backed by our 24 month Fotodiox warranty.Fujifilm G mount mirrorless cameras such as: GFX 50S, GFX 50RNotes: This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. 'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, since manual lens mount adapters do not power the lens, those lenses will not be able to focus. Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode. If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop.
