Nikon T-series lenses are telephoto-type lenses which do not require long-length camera bellows. To increase correction of chromatic aberration inherent in long focal length lenses, Nikon's performance-proven ED glass was used for the first time for lenses for large-format cameras. Image distortion and curvature are also extremely minimized. Combined with Nikon Integrated Coating, the result is outstandingly sharp images, free from flare and ghosting. Lens magnification can be changed with replacement of the rear element.
