Tamron SP 35-210mm F/3.5-4.2 Model 26A
冇毛,少塵,連膠HOOD
This particular SP lens is a splendid all-in-one moderate wide angle to long telephoto zoom to keep on your camera for all purpose photography, especially while vacationing or when you don't want to carry around several other lenses. Its average in weight, fairly compact, yet offers better than average optical performance and even has macro at the 35mm position down to 1:3.8! Macro performance is somewhat better than average as well since Tamron chose to move both the zoom and master elements when entering macro mode, rather than merely allowing the front focus elements to extend forward. This lens features a superb optical design coupled with extremely tight machining tolerances within the zooming mechanism. This obviously added to the manufacturing costs. Maintaining precise optical alignment is critical for good optical performance within this or similar wide angle to long telephoto zooms. This lens is an excellent choice for vacations since it covers a broad zoom range and can capture just about any photographic event. For travel, the only other lenses which you would want to take with you is an ultra wide angle lens such as Tamron's SP 17mm F/3.5 or Tamron's 24mm F/2.5 Adaptall-2, and of course your 50mm normal lens for indoor low light situations.

This lens provides better optical performance compared to Tokina's very popular AT-X 35-200 F/3.5-4.5 zoom lens. Although the Tokina lens was slightly more compact and weighed less, you can definitely discern the differences in the machining tolerances between the two lenses when zooming and focusing. Both lenses exhibit zoom creep when the lens it tilted either up or down, but it takes far more tilt (75 degrees from the horizontal with the Tamron versus 45 degrees with the Tokina) before zoom creep with the Tamron becomes an issue. In a nutshell, the less expensive Tokina lens offered decent performance for the average photographer while the more expensive Tamron lens (with tighter machining tolerances combined with a superior optical design) had better optical performance which met the higher expectations of discerning photographers.
