Quick guide from the manual
This lens is designed for DSLR cameras. Key operations include mounting the lens by aligning the attachment marks, selecting focus modes (AF/MF), and utilizing the Vibration Compensation (VC) system for handheld shooting. Always use the zoom lock switch when carrying the lens to prevent barrel extension.
Mounting and removing the lens
Before attaching or removing the lens, ensure the camera is turned off.
- Mounting: Remove the rear lens cap. Align the lens attachment mark on the barrel with the corresponding mark on the camera mount. Insert the lens and rotate clockwise (for Canon) or counter-clockwise (for Nikon) until it clicks into the locking position.
- Removing: Press the lens release button on the camera and rotate the lens in the opposite direction.
Focus and vibration compensation
The lens features an AF/MF switch on the barrel. Set to AF for autofocus using the USD motor, or MF for manual focus. The lens supports full-time manual focus override, allowing fine-tuning even in AF mode by turning the focus ring while the shutter button is pressed halfway.
The VC (Vibration Compensation) switch activates image stabilization. Set to ON for handheld shooting (reduces shake by up to 5 stops). Use Mode 1 for general use and Mode 2 for panning shots. Set to OFF when using a tripod.
Zoom operation and lens hood
Rotate the zooming ring to adjust the focal length between 24mm and 70mm. To prevent the lens barrel from extending under its own weight while carrying, set the lens to the 24mm position and slide the zoom lock switch toward the camera. Push the switch away from the camera to release.
To attach the flower-shaped lens hood, align the hood's attachment mark with the release mark on the lens barrel and rotate clockwise. For storage, the hood can be reversed and mounted on the lens.
Precautions and maintenance
- Cleaning: Use a blower to remove surface dust. For fingerprints, use a lens cleaning tissue with a drop of cleaning solution, wiping in a rotary motion from center to edge. The front element has a protective fluorine coating.
- Storage: Always attach both front and rear lens caps and store in a cool, dry place to prevent fungal growth.
- Moisture: The lens features moisture-resistant construction with seals, but avoid changing lenses in dusty or humid environments.
- Flash: Remove the lens hood when using the camera's built-in flash to prevent vignetting (shadowing).
Technical specifications
- Minimum focus distance: 0.38m (15 inches)
- Magnification ratio: 1:5
- Optical construction: 17 elements in 12 groups
- Diaphragm: Rounded 9-blade
- Vibration Compensation: 5 stops (CIPA standard)
Troubleshooting
- Lens creep: The barrel may extend when pointed downward. Always use the zoom lock switch at 24mm when carrying.
- Image blur: Ensure VC is ON for handheld shots. For tripod use, set VC to OFF.
- Autofocus issues: Ensure the switch is set to AF and electronic contacts on the lens and camera are clean.
- Vignetting: Remove the lens hood when using the built-in flash, especially at wide-angle settings.
