Before using this product, please carefully read both these instructions and the camera manual.
Note: DX lenses are for use only with DX-format digital single-lens reflex cameras such as the D7000 or D300 series. The angle of view of a lens on a DX-format camera is equivalent to that of a lens with a focal length about 1.5 × longer mounted on a 35 mm format camera.
Attaching the Lens
Removing the Lens
Supported focus modes are shown in the following table (for information on camera focus modes, see the camera manual).
Camera focus mode | Lens focus mode | |
M/A | M | |
AF | Autofocus with manual override | Manual focus with electronic rangefinder |
MF | Manual focus with electronic rangefinder |
M/A (Autofocus with Manual Override)
To focus using autofocus with manual override (M/A):
The Focus Limit Switch
This switch determines the focus distance limits for autofocus.
FULL: Select this option for subjects that may be Pb closer than 0.2 m (0.7 ft).
–0.2 m: If your subject will always be at distance of at least 0.2 m (0.7 ft), select this option for faster focusing.
Aperture is adjusted using camera controls. If the camera is in exposure mode A or M, aperture will automatically be adjusted by up to 1.2 stops to maintain the same effective f-number at different focus distances.
If the camera offers depth-of-field preview (stop down), depth of field can also be previewed in the viewfinder.
The reproduction ratio is the ratio of the apparent size of an object to its true size. If, for example, the image on the image sensor is one-third of actual size, the reproduction ratio is 1: 3.
If desired, the reproduction ratio can be selected using the reproduction ratio indicator.
Example: Using the Reproduction Ratio Indicator
To shoot at a reproduction ratio of 1: 3, select manual focus and rotate the focus ring until the focus distance mark aligns with the number "3" in the reproduction ratio indicator, then move the camera forward or back until the subject is in focus.
To prevent blur caused by camera shake, mount the camera on a tripod and use a cable release or remote cord. Close ups are generally associated with extremely shallow field depths; for greater depths of field, stop down the lens, choose longer exposure times, and position the camera so that the focal plane is parallel to the portion of the subject you wish to photograph. When using a lens hood, be careful that the hood does not touch the subject.
The lens f-number indicates the brightness of the subject at a focus distance of infinity; higher reproduction ratios result in reduced subject brightness. The actual brightness is referred to as the "effective f-number", and the amount that exposure compensation has to be raised to account for the loss in brightness as the "exposure factor".
With this lens, the higher the reproduction ratio (the shorter the focus distance), the darker the image that falls on the image sensor and the higher the effective f-number. The camera automatically compensates for this effect when metering exposure or adjusting flash output using TTL flash control, and shows the adjusted value for aperture in the control panel and viewfinder displays.
When using the built-in flash on cameras equipped with a built-in flash unit, shoot at ranges of 0.6 m (2 ft) or more and remove the lens hood to prevent vignetting (shadows created where the end of the lens obscures the built-in flash).
The lens hoods protect the lens and block stray light that would otherwise cause flare or ghosting.
Align the lens hood lock mark (— ) with the lens hood mounting mark (
) on the lens (
).
When attaching or removing the hood, hold it near the symbol on its base and avoid gripping it too tightly. Vignetting may occur if the hood is not correctly attached. Ua The hood can be reversed and mounted on the lens when not in use. When the hood is reversed, it can be attached and removed by rotating it while holding it near the lock mark ( —
).
