DA 12-24mm vs Sigma and Tamron 10-24mm Comparison
The Tamron SP AF 10-24mm f/3.5-4.5 is a great alternative when price is the deciding factor. The lens has the widest zoom range of the lenses compared and the widest field of view at the short end. The build quality is adequate and the zoom action is smooth. The zoom ring is large and well placed fitting nicely in to your hand. The focus ring is larger than the Pentax but smaller that the Sigma.
The lens hood, if installed reversed over the lens, is bulky and gives it a total diameter of just under 4 inches. The lens has distortion at 10mm and 12mm but once you get past 12mm it drops significantly. The problem with vignetting is relatively minor and the distortion does improve once you move towards 24mm. The Tamron SP AF 10-24mm f/3.5-4.5 lens is also prone to chromatic aberration but improves once you start to move towards 24mm. The one area that this lens struggles with is sharpness but it improves once you stop down the aperture.
The Tamron SP AF 10-24mm f/3.5-4.5 lens currently retails for $499.00 at B&H photo, which places the Tamron at the low end of the lenses being reviewed. Currently Tamron is offering a rebate for $50.00, which would lower the overall cost to $449.99*.
