Close-distance scale
Precautions on close-distance scale
(For DA 16-45mm f/4ED AL, DA18-55mm f/3.5-5.6 AL)
In the close-distance scale range (the distance scale in the orange area), when shooting at the maximum aperture, image quality deterioration in the picture corners may result because of the optical characteristics of the lens.
When taking a picture in this range, we recommend that you use a smaller aperture, stopping down from wide open.

About the PL filter window
If a polarizing filter is attached to the DA lens, you can easily turn the filter via the PL filter window on the bayonet-type hood.
How to use the lens hood with polarizing filter window
1. Remove the PL filter window cap by sliding it in the direction as shown above.
2. Turn the outer rim of the circular polarizing filter from the PL filter window as shown above.

3. Attach the PL filter window cap.
✍
Memo:
• When shooting, be sure the PL filter window cap is in place to make that the lens hood is being used to maximum effect.
18
FILTERS
Mount the filter into the screw thread in front of the lens.
✍
Memo:
• The compatible filter size for all the lenses are listed on pages 22-23.
Precaution on filters
• Since the filter becomes a part of the optics when attached on the lens, handle it in the same way you handle the lens with care to dust, dirt and scratches. Normally, attaching two or more filters on a lens is not recommended. However, attaching a circular polarizing filter and another filter would not be a problem.
• Use a circular polarizing filter with Autofocus camera for proper exposure and autofocusing.
19
Attaching the 30.5mm filter to the DA 40mm f/2.8 Limited lens
Normally, you attach the 49mm filter to the front of the lens. But as shown in the diagram, you can also screw on a 30.5mm filter to the back of the dedicated hood.
About Using a Polarizing Filter
• If you attach an older type Pentax polarizing filter to the DA 16-45mm f/4 ED AL or DA
18-55mm f/3.5-5.6 AL lens, the dedicated hood cannot be attached over the filter. Also, the hood might or might not be attachable if a non-Pentax polarizing filter is attached to the lens.
• Do not attach an older type Pentax polarizing filter to the DA 14mm f/2.8 ED (IF). The filter will cause vignetting. Instead, use the new Pentax polarizing filter which will not cause vignetting.
20
PRECAUTIONS WHEN USING THE LENS WITH A FLASH
Built-in Flash
The built-in flash can not be used when the distance is less than 0.7m. When the flash is used within 0.7m, it causes incorrect exposure control and vignetting in the picture corners.
• Refer to the “Compatibility of DA Lenses with the Built-in Flash” chart on page 18 for information on the compatibility of the built-in flash with the lens being used. Furthermore, please note that when using the -series camera, a warning indication does not appear even when taking a picture with a built-in flash that is incompatible with the lens being used.
• If the built-in flash is used with the lens hood attached to the lens, the flash light will be blocked by the lens hood. Always make sure to remove the lens hood before using the built-in flash.
External Flash
● DA 14mm f/2.8ED (IF)
The AF360FGZ external flash unit with the wide-angle panel only can be used, and the lens hood can be attached as well. Other external flash units are not recommended to use because their coverage angle is not compatible with the angle of view of the lens.
● DA 16-45mm f/4ED AL, DA18-55mm f/3.5-5.6 AL, DA 40mm f/2.8 Limited
When using the external flash unit, the vignetting will not occur with the lens hood attached to the lens if the flash covers its angle up to 24 mm (equivalent in 35mm format).
For further details, refer to the operating manual for your external flash unit.
