Competition

The ultra-wide APS-C zoom market is crowded albeit most offerings are old to ancient by now. As mentioned, APS-C DSLRs received little love from CaNikon lately (...). The most obvious competitor of the Tamron (shown to the left) is the Canon EF-S 10-22mm f/3.5-4.5 USM (center) ... released in 2004(!). While it doesn't feature any image stabilization, it's probably your best bet still and it's only marginally more expensive. If you are on a tight budget, you may also consider the Canon EF-S 10-18mm f/4.5-5.6 STM IS (to the right) - at almost half the price, it is substantially better than the Tamron lens as well. Its plastic mount may not be everybody's darling though. Tokina just released the atx-i 11-16mm 2.8 CF (not shown) which may be the sharpest of the bunch albeit you would have to live with a very short zoom range and fairly high CAs.

Verdict

The Tamron 10-24mm f/3.5-4.5 Di II VC HLD is an affordable option in this market segment but its affordability comes with a number of compromises. Now, if you just intend to shoot at f/8, you can get reasonably happy with this lens. At this setting, it is quite sharp across the image field. However, at large aperture settings, it's mediocre at best with soft corners. Adding insult to injury, there's also a heavy field curvature at 10mm. Lateral CAs are Okay at the image borders but they can be disturbing in the image corners. Image distortions are about average for a lens in this class with heavy barrel distortion at 10mm. Vignetting is very noticeable at large-aperture settings.

The build quality of the Tamron lens is decent and about in line with what you can expect from a modern, consumer-grade offering. Tamron uses high-quality plastics here and they even added some basic weather sealing. The zoom action is a bit on the stiff side but we prefer it like this on ultra-wide zoom lenses actually. Manual focusing is not a joy due to the cheap focusing ring but then most users won't bother anyway. We used the EOS 7D II for testing and the AF wasn't overly accurate. To be fair - that's not unheard with such wide lenses. However, in real life, it's not a big deal because the depth-of-field is quite immense anyway. On the positive side, the AF is reasonably fast with some minor noise emissions. A positive aspect is certainly the image stabilizer which can save the day in low light situations - and it can help to avoid the weak performance at fully open aperture.

The Tamron is not a bad lens but, ultimately, it is just not "good enough". There are simply better options out there.
