1 The maximum object dimensions shown in the table are 90% of the theoretical maximum dimensions, providing a safety factor for magnification and alignment errors.2 Image-side working f-number with lens aperture fully open. For combinations with teleconverters, the minimum image-side f-number is increased by the teleconverter magnification.3 Lenses operated at smaller f-number may show reduced resolution, especially near the edge of the field of view.4 Depth of field is calculated at f/11 for lenses with minimum operating f/# < f/16 (f/22 for all others) and for 30-µm allowable blur at the image (camera) plane.5 In combination with teleconverter 1.5x (p/n 59 LGZ 415).6 In combination with teleconverter 2x (p/n 59 LGZ 420).7 Teleconverters cannot be used with certain types of 3-CCD color cameras.
Note: Distortion is less than 1.2% for all lenses. Contact NAVITAR for specific distortion characteristics for a particular lens.
