Tamron’s super superzoom, a 28–418mm equivalent with built-in Vibration Compensation, offers great close-up potential: The magnification ratio was 1:2.9, and there was no edge falloff at three of four tested focal lengths.
A 29–400mm equivalent, this lens offers the broadest zoom range of any Sigma and is the company’s only superzoom with stabilization. Smooth zoom action, rapid and silent AF, and only Slight-range distortion.
APS version of the classic Tamron 90mm f/2.8, this lens is vastly improved, with groundbreaking f/2 aperture. Excellent optics make this a favorite portrait lens as well as close-up tool. Maximum magnification: 1:0.91.
