{{NeedPhotos}}The '''[[Carl Zeiss]] CFE Distagon f/4 40 mm FLE''' is a specialized wide angle lens, used on [[Hasselblad]] cameras.

<!--this claim is taken from the second link below, but seems very dubious. The CFE does not have two rings, only the usual focus ring. Floating elements are usually used to improve sharpness at close focus distances. -Vox
== Overview ==

Technology often glossed over, the "FLE" — floating lens element designation indicates that the photographer can tune controls to correct for converging or diverging line distortion.

This [[Zeiss]] approach distortion control correction should not be confused with [[Minolta]]'s or [[Nikon]]'s architectural lens application approaches It offers a fine tweaking adjustment to apparent pincushion/barrel distortion. Nikon's approach has been, traditionally, to produce a much larger than format coverage, extremely flat field, low distortion lens and offset it keeping the subject and image planes parallel. The more versatile Minolta approach had been to vary the curvature of the focal plane with an internal floating group to best optimize non convergence or divergence of image parallel straight lines.

This lens would typically be employed in architectural photography at a variety of distances.
