28–300mm · f/3.5–6.3
The Tamron AF 28-300mm F/3.5-6.3 XR Di LD Aspherical (IF) Macro is a compact, lightweight superzoom designed for both full-frame and APS-C cameras. Optical strengths include decent sharpness at the wide end, peaking at f/8, and effective vibration compensation (VC) allowing two stops slower shutter speeds. Weaknesses include high chromatic aberration at wide and telephoto ends, moderate distortion (barrel at wide, pincushion at tele), and slow autofocus. Build is solid with plastic barrels and a zoom lock (Photo Review). It suits travelers or casual users wanting a wide-to-tele range in one lens, but not for fast action or critical sharpness.
