The-Digital-Picture has completed their extensive review for the brand new Tamron 10-24mm f/3.5-4.5 Di II VC HLD lens. If you're looking for a great wide angle option for your APS-C DSLR, you can't go wrong with this new Tamron. I think the VC really separates it from Canon's terrific EF-S 10-22 f/3.5-4.5.
From The-Digital-Picture:
The advantages of this lens start on the surface, with a great-to-handle shape and sharp looks. To get great images requires having a lens with you and the size and weight of this lens makes it easy to carry and comfortable to use for even long periods of time. Weather sealing is another advantage of the 10-24 VC, featuring a ready-for-whatever mindset by design. The image quality delivered by this lens competes well against the other options and when slow shutter speeds begin to adversely affect image quality, this lens' excellent vibration compensation system will, by far, differentiate it from most of the crowd.
