*1 The vibration-resistant types are designed to have their apertures replaced. When shipped, the OPEN aperture is attached to the lens, so replace this with one of the other included apertures (F4, F8, or F16) as necessary. To use the f-stop (aperture) in the OPEN mode, use the lens without removing the OPEN aperture.
*2 Installing the lens at a distance from the target shorter than the minimum working distance listed in the specifications makes it very likely that the lens will drop out due to vibrations. If the lens is installed in such a position, implement separate countermeasures to prevent the lens from dropping out.
*3 This indicates the specification for the compatible image sensor size. The value in parentheses applies to a 1/3" image sensor size.

*1 The above values were calculated according to optical design values. Actual values for individual lenses will differ according to precision of assembly.
*2 WD indicates a working distance at reference magnification. WD will vary depending on magnification adjustment.
*3 Depth-of-field applies to an F-stop of 16. Depth-of-field varies depending on F-stop setting.
The indicated depth-of-field is a theoretical value that assumes 1/2" image sensor size and a horizontal resolution of 320 lines. (Circle of least confusion is 40 µm 1.57 Mil in the image)
