17 Apertures and Click Stops Certain lenses have a white dot next to the maximum aperture. The white dot indicates a difference of one aper- ture stop. For example, as shown on the right, the white dot next to f/2 indicates f/2.8. If there is no white dot for a click stop between the f/numbers, the click stop indicates the respective f/number shown[...]

Using the Infrared Index If you use infrared film with an R2 or O2 filter, the point of focus differs from normal shooting (with visible light). This means the point of focus must be corrected. * Infrared film cannot be used with the MZ-S, MZ-60, and cam- eras since these cameras use infrared light to detect film transport operations. When the subj[...]

19 Zoom Lens Infrared Index With a zoom lens, the focusing cor- rection amount for infrared film shoot- ing varies depending on the focal length. As shown in the illustration, zoom lenses have an infrared index. Correct the focus with respect to the focal length used.

29 Note: Using a Circular Polarizing Filter * In the case of the FA 77mm f/1.8 Limited lens, attaching certain dis- continued circular polarizing filters (including the PENTAX Type-A Circular Polarizing Filter) prevents the built-in hood from being pulled out. * With an autofocus camera, use a circular polarizing filter instead of a polarizing filt[...]

Cautions When Using Flash 30 With the built-in flash Use the built-in flash for subjects at least 0.7 meter away. If the subject is closer than 0.7 meter, overexposure may result.
