Owner's of the Tamron Camera Lens AFB005NII700 gave it a score of 0 out of 5. Here's how the scores stacked up:
-The optical design for Di-II takes into consideration the various features of digital single
reflex cameras. However, due to the configuration of the digital single reflex cameras,
even when auto focus accuracy is within specifications, the focal point may be a little
forward or behind the optimum point when shooting with auto focus under some
conditions.
-The image circle of Di-II lenses are designed to match the digital SLR cameras using the
image sensors equivalent to APS-C (approx. 15.5x23.2mm). Do not use Di-II lenses with
cameras using image sensors larger than APS-C. Using Di-II lenses with such cameras
may cause vignetting on the image.
-The Tamron lenses described here employ an internal focusing (IF) system. Because of
the characteristics of this optical design, the angles of view at distances other than infinity
are wider than that of the lenses applying an ordinary focusing system.
-When the built-in-flash on the camera is used, adverse photographic phenomena such as
corner illumination fall-off or vignetting at the bottom part of the image may be observed,
especially in wide angle ranges. This is due to the inherent limitation of the coverage of
the built-in-flash, and/or the relative position of the flash to the edge of the lens barrel
which causes shadows on the image. It is strongly recommended to use a suitable
separate flash unit provided by the camera manufacturer for all flash photography. For
further details, please read the “built-in-flash” article on the instruction manual of your
camera.
-When using the lens in the telephoto focal range, please be careful of camera shake. To
reduce blur, turn the VC (Vibration Compensation) switch on. To reduce image blue
without using the VC function, follow these steps.
To avoid camera shake on digital cameras, use higher ISO settings and for film cameras,
use higher ISO film to obtain higher shutter speeds. Using a tripod or monopod is also
effective.
When hand-holding the camera to take pictures, stand still opening your legs slightly
apart, hold your elbows in firmly against your chest, and hold the camera firmly against
your face. If possible, lean against something to steady yourself or place the camera on
something to secure the hold. Especially when hand-holding your camera, you will be
steadier if you hold your breath while your press the shutter button down gently and
firmly.
-When set on AF mode, interfering with the focusing ring may cause serious damage to
the lens mechanism.
-Certain models may indicate the maximum and minimum aperture values of the lens in
approximate numbers. This is inherent to the design of the camera and not an indication
of an error.
-Please be aware that there is no infrared index line on any models listed in this owner’s
manual, and therefore, practically no black-and-white infrared file can be used with these
lenses.
-When using a special filter such as a PL filters, use low profile filters. The thick rim of a
normal filter may cause vignetting.
