MACRO SWITCHOVER MECHANISM

The model 672D allows macro photography by operating the macro selector switch. The maximum magnification ratio in the macro photography mode is 1:2 (f = 300 mm, 0.95m).

It is necessary that the zoom be aligned to 180-300 mm when switching the macro selector switch from Normal to Macro. In addition, it is necessary that the focus ring be aligned to 1.5 m to infinity to switch from Macro to Normal.

SWITCHING TO MACRO PHOTOGRAPHY

First, turn the zoom ring to align the zoom between 180 and 300mm. Next, slide the macro selector switch from the Normal to the Macro position. The lens is now switched to the macro photography mode.

When in the macro photography mode, the focus ring rotates continuously from infinity to the minimum focus distance of 0.95m. The magnification ratio reaches a maxi- mum when the focus distance is 0.95 m at 300 mm. The magnification ratio at this time is 1:2.

When in the macro photography mode, the zoom ring can only be rotated over the range of 180mm and 300mm. Angle of view can only be adjusted over the range of 180mm to 300mm when in the macro photography mode.

The macro selector switch cannot be operated unless the zoom ring is between 180mm and 300mm. Always make sure to align the zoom ring between 180mm and 300mm before operating the macro selector switch.

CANCELLATION OF MACRO PHOTOGRAPHY

First check that the focus ring is aligned to 1.5m or farther (1.5 - infinity). (Turn the focus ring to 1.5m or farther when it is set to a distance closer than 1.5m). Next, slide the macro selector switch from the Macro position to the Normal position. The macro photography mode is now cancelled.

The focus ring can only be turned between infinity and 1.5m when the macro selector switch is set to the Normal position (when macro photography is cancelled.) It cannot be turned to a distance closer than 1.5m.

The macro selector switch cannot be operated unless the focus ring is set to a dis- tance between 1.5m and infinity. Always make sure to set the focus ring between 1.5m and infinity before operating the macro selector switch.

672D specifications

The Tamron 672D is a highly regarded lens known for its versatility and excellent optical performance. Designed for use with various camera systems, it caters to both amateur and professional photographers who seek quality and reliability in their image-capturing tools. One of the standout features of the Tamron 672D is its focal length range, which allows photographers to tackle a diverse range of subjects. Its zoom capabilities, which typically extend from wide-angle to telephoto, make it an ideal choice for everything from landscapes to portraits and close-up shots.

One of the most notable technologies employed in the 672D is the use of advanced optical design. This lens utilizes multiple glass elements, including low dispersion (LD) and aspherical elements, to minimize chromatic aberration and distortion. The result is exceptional sharpness and clarity throughout the zoom range, ensuring that images are rendered with precision and detail. Furthermore, the lens features a fluorine coating that repels water and oil, reducing the potential for smudges and streaks on the front element, which is particularly useful when shooting in challenging weather conditions.

The Tamron 672D also incorporates a powerful autofocus system that ensures quick and accurate focusing, which is vital for capturing fleeting moments. The autofocus motor operates quietly, making it suitable for both still photography and videography. Additionally, the lens includes a manual focus option, granting photographers the ability to fine-tune their focus for critical shots.

Build quality is another strength of the Tamron 672D. The lens is designed with a robust yet lightweight structure, making it easy to handle during extended shooting sessions. It often comes with a zoom lock mechanism to prevent accidental zoom movement during transport, adding to its practicality. The ergonomic design ensures a comfortable grip, allowing for stability even in challenging shooting environments.

In summary, the Tamron 672D is a well-rounded lens that combines advanced optical technologies with user-friendly features. Its versatility, optical performance, and robust build quality make it an excellent choice for photographers looking to enhance their creative capabilities. Whether shooting portraits, wildlife, or expansive landscapes, the 672D is a reliable companion that delivers stunning results across a wide variety of photographic scenarios.
