What’s in my Camera Bag? Tamron’s 24-70mm f/2.8

Tamron’s SP 24-70mm f/2.8 Di VC USD lens is equipped with VC (Vibration Compensation) image stabilization, USD (Ultrasonic Silent Drive) and is designed for full-frame cameras but works well with cameras that have APS-C sensors—such as the Canon EOS Rebel T4i that I initially tested it with. On these cameras, it produces the equivalent focal length of 38-112mm.

To maintain high image quality, the lens uses three Low Dispersion elements, three glass molded aspherical lenses, one hybrid aspherical lens and two XR (Extra Refractive Index) glass elements. Bokeh fans will like its rounded diaphragm that produces a nearly circular shape allowing the lens to create images with attractive out-of-focus areas. The zoom function is extremely smooth to use and the build quality is impressive and easily as good as a camera brand manufacturer’s lens. Overall the SP 24-70mm lens look and feels ruggedly solid.

The SP 24-70mm lens uses USD (Ultrasonic Silent Drive) to power its speedy AF although the Rebel T4i’s Live View mode (only) appears to slow it down a bit. Its compact image stabilization unit contributes to the lens’s relatively lightweight (29.1 ounces) for such a fast lens and the balance even with a small SLR such as the Rebel T4i was surprisingly good. All this wonderfulness doesn’t come cheap; the 24-70 mm F/2.8 Di VC USD costs just under $1300 but when compared to Canon’s own 24-70mm f/2.8 at $2299, looks like a bargain. The lens is also available in Nikon and Sony mounts.

This is a relatively new lens and I expect to be testing it with some of my other Canon SLRs including the EOS 60D and EOS 5D. Look for new images here as well as on my Google+ page.
