Tamron’s new AF28-300mm F/3.5-6.3 XR Di VC lens has a Vibration Compensation (VC) mechanism that uses three coils to move the lens electromagnetically based on signals from the movement of three steel balls. Tamron claims that it combats camera-shake through all focal lengths, and they’ll let you try it out with their “VC simulator”. Click the shutter with VC on and off and compare the results. Look for our test of Tamron’s AF28-300mm F/3.5-6.3 XR Di VC lens shortly after we receive a production version in the Pop Photo Lab.
