1. The maximum object dimensions shown in the table are 90% of the theoretical maximum dimensions, providing safety factor of magnification and alignment errors.
2. Lenses operated at smaller f/# may show reduced resolution, especially near the edge of the field of view.
3. Depth of field is calculated for a 30-µm allowable blur at the image (camera) plane at f/11 (for lenses with minimum operating f-number<f/16) or f/22 (for all others).
4. Teleconverters 59 LGZ 420 and 59 LGZ 415 cannot be used with certain types of 3-CCD color cameras.
Note: Distortion is less than 2% for all lenses. Contact Navitar for distortion characteristics for a specific lens.
