This ultrawide lens is not performing well at 10 mm. It's having very noticeable barrel distortion at aperture 3.5 (little or more barrel distortion is present in other lens like Canon, Nikon and Tokina too but not this much). On / after aperture 8 it becomes okay at 10 mm and above.

This is very good lens specifically for Wide Angle Photography comparable to Canon Lens. Focal length range is an advantage over other lenses. Build Quality is also good and works very well on my Canon EOS 60D.

Consistent Output; Easily Interchangeable; Fast / accurate auto-focus; Strong Construction

This is a great wide angle lens, particularly if u like landscapes or in my case, star trails. It's a little on the heavy side but very simple to use. As long as u keep away from stray artificial light sources when shooting at night, you will be extremely happy with this lens.

After Tamron's ambitious 10-24mm wideangle zoom produced inconsistent MTF results in a previous WDC test, we decided a re-test was in order to see whether our test lens was a one-off.

Extended zoom range; low price-point; minimal colour fringing

Performance at 24mm

I purchased this lens to use with my D90 and I have found that it does not work with the auto zoom function on my SB600 speedlight as I would expect from any lens that is supposed to be compatible with a Nikon camera. You need to use manual zoom function which is a bit of a pain.

The SP AF10-24mm f/3.5-4.5 Di II is Tamron's second ultra-wide-angle zoom lens for cameras with APS-C sized sensors. Replacing an 11-18mm f/4.5-5.6 lens, it provides a wider zoom range, particularly at longer focal lengths.

An ultra-wide angle zoom designed for digital SLRs with an APS-C size sensor, which covers a range that is perfectly suited for landscape photography.

The Tamron 10-24mm offers a large focal range and a variable f/3.5-4.5 aperture. However, it doesn't offer a built-in focusing motor and emits some buzzes and whirs while focusing. The lack of an AF motor also means that it won't be able to autofocus when mounted on Nikon bodies without their own AF...

Yes, I would recommend this to a friend

Clear Optics; Firm Mount; Strong Construction

Slow autofocus

I enjoy using this lens. The perspective is fantastic. The distortion at 10mm is hardly noticeable unless you are in close. The usual assumption is that lens of this type is best for landscapes, but this lens is also excellent for those close in shots also.

Good Optical quality and value for this price range; Excellent and useful zoom range; A lot of fun to use indoors or up close; Good build quality; Lens flare and CA are well controlled in most lighting

Autofocus is a bit slow; Lens Hood is very large; Huge Filter Diameter; Built in Flash is not useable with this lens unless you can deal with the large shadow at the bottom of the frame
