Exposure Rate

When the lens is moved outwards to increase the magnifications ratio for shooting close- ups, the actual brightness on the film decreases, and the effective F number changes. For auto exposure photographing, using an external exposure meter, or when using and exter- nal light-adjusting flash however, the exposure must be corrected for this decrease in brightness according to the magnification ratio. For the amount of the correction, refer to table 12.

DEPTH-OF-FIELD

With a camera equipped with a depth-of-field preview button or an aperture-stop-down mechanism, the depth of field can be directly observed through the viewfinder screen of your camera. For the operational details, read the instruction manual of your camera.

INFRARED PHOTOGRAPHY

Please be aware that there is no infrared index line on any models listed in this owner's manual. Therefore practically no black-and-white infrared film can be used with these lenses.

PRECAUTIONS IN SHOOTING

Do not use the lens hood when using the camera's built-in flash. Also, when shooting close- ups, the lens unit may obstruct the light of the flash even when not using the lens hood, resulting in vignetting at the bottom part of the image. Thus, we recommend using a special externally mounted flash or flash photography.

Also refer to the section of your camera's instruction manual pertaining to the use of the built-in flash.

When using a B01 with a tele-converter, use the manual focus. When a tele-convert- er is used with the macro lens, the autofocus may not operate correctly, depending on the focusing distance. This is due to the camera's mechanical system. Use a Tamron tele-con- verter with a Tamron lens or best results. Tele-converters produced by other manufacturers may not mount properly and/or cause malfunctions. When a tele-converter is mounted onto a lens, the focusing ring normally feels heavier when rotating.

When using the lens in macro range, it may be necessary to use a tripod to avoid camera shake. Using high-speed film (ISO 400 or faster) with a fast shutter speed is also helpful to reduce the influence of camera shake.

Do not forcibly turn the focusing ring when camera and/or lens is/are set in the AF mode. Doing so could damage the lens and/or camera.

Certain camera models may indicate the maximum aperture values of the lens as approximate numbers. This is inherent to the design of the camera and not an indication of error.
