Physical Views & Controls
As we have seen on other Tamron models, the zoom control, while comfortable, is a bit stiff when zooming out. It does zoom back in very easily however. The zoom lock allows you to "lock" the lens in its wide (18mm) position for safe travel. To zoom the lens you rotate the wheel in a clockwise fashion, which is the opposite of Canon's zoom lenses.
First introduced on their A005 telephoto zoom lens, Tamron has incorporated their new VC (Vibration Compensation) image stabilization system in the B008. This is a tri-axial system, which they claim gives you up to a 4 stop advantage over a non-IS lens. On the right you can see an expanded view of the VC system's complex design (photo courtesy of Tamron), which overall helps increase the chances that you'll capture blur free photos when shooting handheld and in lower lighting conditions.
The B005 uses a filter thread of 62mm to allow you to attach filters to the lens as well as a bayonet mount on the end for accessories like the included lens shade.
Tamron includes a large "flower-shaped" lens shade or hood. It measures about 1.5 inches at it's longest point, and features a ribbed interior to help reduce reflections. For storage, you simply reverse the hood and attach it to the lens. However, this blocks the focus control completely.
Currently, the B005 is being offered for both Canon and Nikon dSLRs. Above you can see the Canon EF mount, which is constructed using durable metal materials. One important note, when using the Nikon version of this lens, the Nikon dSLR must have an internal focus motor in order to use AF functionally of this lens.
