Fotodiox Pro TLT ROKR-Tilt/Shift Adapter Pentax 6x7 (P67) Lenses to Canon EOS

  

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 can be used to eliminate the convergence of vertical lines, know as keystoning, when photographing tall subjects such as buildings.
