This wide-to-moderate tele step-up, a 26–78mm equivalent, offers added speed, sharpness, and distortion control. AF is fast and accurate, if slightly whiny.
DSLR photographers looking to move up from the distortion and limited sharpness and speed of their kit lens will welcome this new wide-to-medium tele. Tamron has toted out big-gun technology for its 26-78mm equivalent ($450, street). This Di II (digital only) optic boasts a high speed, constant aperture, two aspheric elements, internal focusing, one element of low-dispersion glass, and another of a super low-dispersion XR (Extra Refractive Index) glass for, the company claims, better control of chromatic aberration.
