User manual TAMRON SP AF 90 2.8 DI MACRO 1:1 (MODEL 272E)

[. . . ] * For further details, please read the instruction manual of your camera. SWITCHING BETWEEN AF & MF MODES (Ref. 2 & 3) Nikon and Canon models Simply move the focusing ring forward (to AF) and backward (to MF) to change the focusing mode between autofocus (AF) and manual focus (MF). Minolta and Pentax models Move the focusing ring forward (to AF) and backward (to MF) and at the same time, set the AF/MF selector switch of the camera body to the coinciding focusing mode (AF or MF). Mount Nikon, Canon Minolta, Pentax AF/MF Switching Operation Move focusing ring only Move and switch both focusing ring and selector of camera body * Carefully read "Autofocus" and "Manual focus" sections below and operate the camera and lens accordingly. In addition, please refer to the instructions related to focusing operations of your camera. FOCUSING (Autofocus) (Ref. [. . . ] Cameras read the different lens openings and automatically adjust the exposure properly. * For further details, please read the instruction manual of your camera. ATTACHING THE LENS HOOD (Ref. Align the index mark on the hood with the corresponding index mark on the lens. Place the hood onto the hood's attaching bayonet ring. Turn the hood clockwise until it clicks (6-2). The index mark (O) on the hood appears on the top when it is correctly attached. (7-3) Stowing lens hood on the lens (Ref. Then align the index mark (O) on the hood with the index mark on the lens. Place the hood onto the hood's attaching bayonet ring. Turn the hood clockwise until it clicks. The index mark on the hood appears at the top when correctly stowed. USING THE FOCUS LIMITER (Ref. Fig 9) When the focus limiter knob is set to "LIMIT", the camera can be autofocused with greater speed within that range. For range from maximum close-up to infinity Set the focus limiter knob to "FULL" For close-ups (0. 29m to approx. 0. 4m) Set the distance scale to a point between 0. 29m and 0. 4m, and then set the focus limiter knob to "LIMIT". For normal photos (0. 45m to infinity) Set the distance scale to a point between 0. 45m and infinity, and then set the focus limiter knob to "LIMIT". * When shooting close-ups with the focus ring set between about 0. 40m and 0. 45m the focus limit knob cannot be set to LIMIT. This is due to the camera's mechanical system. ABOUT MACRO PHOTOGRAPHY (Ref. 12) From infinity to the macro zone, you can use AF or MF operation. Since the distance scale and the magnification scale are imprinted side by side, you can get a general idea of the magnification when shooting a picture. 272E Minimum Focus Distance Maximum Magnification Ratio Magnification Scale 0. 29m 1:1 1:10 - 1:1 * For the correlation between the photographic distance and photographic magnification, please refer to table 12. EXPOSURE RATE (Ref. 12) When the lens is moved outwards to increase the magnifications ratio for shooting closeups, 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 external 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 (Ref. 13) 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. [. . . ] Use a lens cleaning tissue or lint cloth with a drop of cleaning solution to remove fingerprints or dirt on the glass lens surface with a rotary motion from the center to the edge. Use a silicon cloth to clean your lens barrel only. Clean the lens after shooting near water or in any humid place. Store your lens in a clean, cool and dry place. [. . . ]
