Distagon T* 4/40 IF CFE

  • A sophisticated super wide angle lens with outstanding performance.
  • Particularly suited to be used with digital backs in professional studio photography.
  • A newly developed focusing mechanism with reduced torque enables smooth and precise focusing.

The Distagon® T* 4/40 IF CFE lens is a sophisticated super wide angle lens with outstanding performance. It is designed for the 6 x 6 format. Compared to its predecessor it is improved in several aspects:

The optical performance is unusually good even at wide open aperture. Detail resolutions up to 200 lp/mm can be reached on films with adequate resolving power. With this potential the Distagon T* 4/40 IF CFE lens recommends itself for aerial photography and other very demanding tasks.


  • In the corners of the image the performance is significantly higher than that of the predecessor at all apertures.
  • The image angle is slightly wider than that of the predecessor.
  • The image quality in the close-up range, especially the image flatness, is much better than that of the predecessor, especially at large apertures.
  • At the close-up limit, the Distagon T* 4/40 IF CFE lens is able to frame slightly smaller objects than its predecessor could.

The Distagon T* 4/40 IF CFE lens is particularly suited to be used with digital backs in professional studio photography. Here, it is a shorter focal length alternative to the digitally well-accepted lens Makro-Planar® T* 4/120 CFE.
The Distagon T* 4/40 IF CFE lens features internal focusing and automatic optimisation of correction over the entire focusing range from infinity to close-up. A newly developed focusing mechanism with reduced torque enables smooth and precise focusing. The ergonomics are further enhanced by the focusing ring being much wider and better positioned than that of the predecessor.
