The advanced design of the Linhof Aero Technika 45EL has made it the preferred tool for commercial, industrial and military photographers looking for a large capacity heavy-duty hand-held camera system capable of delivering brilliant aerial pictures with maximum sharpness and all the richness of detail and the wealth of information that only 4x5" film can provide. While the camera is primarily used for air-to-ground photography, it can also be used for air-to-air shots, as all Aero Technika lenses (except the 90mm lens)are supplied in helical focusing mounts to ensure optimum sharpness also at closer distances. With its remote control operation, the Aero Technika 45 system is also highly suitable for fixed installation in the aircraft and for observation or registration photography on the ground.
