• Do not use the flash when the close-up lens is attached to the camera. The image
will be improperly recorded and the flash will not adjust its output correctly.
• Use the close-up lens with the focal length set to the maximum telephoto setting.
Lens Hood LH-DC58
This lens hood features a 58 mm thread. It can be
used to shield out unwanted light, in a blacklit
scene for example, and helps to produce clear
images with less ghosting and flare.
Attaching a Lens / Lens Hood

Attach a lens or lens hood by aligning it
with the lens mounting thread and

• Please note that images will not merge properly with the bundled PhotoStitch
program on the computer when they are shot in 
 mode with a wide converter
or close-up lens installed.
• To protect the lens, hold it with one hand while screwing it on with the other.
• Clean the lens completely of all dust and dirt before installing it on the camera.
Dirt may confuse the focus.
• Please take due caution when handling the lenses because it is easy to leave
fingerprints on them, which confuses the focus.
