Pros: Unbelievable value for money, Sharpness and contrast, f32 minimum aperture, relatively small 67mm filters, quite close focus
Cons: Jerky zoom action, plasticky, general handling, AF, lightness (possibly)
Opinion: I wasn't going to write a review as there are already so many written. Firstly, I don't much like this lens, in use, but I DO like very much its image quality and I was almost forced into buying it, needing a very cheap fast standard zoom for low-light music and performance photography for my D7000. It needed to be not obviously soft at edges at f2.8 (Sigma 17-50mm f2.8 is) and be able to perform well wide open at all focal lengths. From f4 to f11, the sharpness is the equal to any zoom I've used (inc pro Nikkors) and is very satisfying for landscapes in low light. I also use a Nikkor 16-85mm VR for landscapes which also has great image quality in a well built unit that's nice to use and with VR also. But it's obviously not great in low light and when zoomed out. However, after nearly two years with the Tamron and some beautiful sharp images that rank among my best, I keep looking at reviews of other lenses. . My big hands yearn for a lens more substantial than the 400g Tamron and the sticky zoom irritates me often. Having to disconnect AF on both lens AND camera to override the AF is a pain too. The benchmark Nikkor 17-55mm was designed over a decade ago and its weight and build is just too much for practicality and while used prices have dropped hugely now, it is still too expensive for me and there are some real rogue ex-pro battered examples out there. The Sigma, as I said is an attractive proposition, weight, size, OS and price but whilst apparently being optically excellent from f4, on, it's still variable at wide open. The better built newer, with VC, Tamron seems to have suffered an overall loss in absolute quality - Tamron still offer the older lens under review in their current line-up, so even they acknowledge that the quality is better here than the newer one. I'm now considering the used only Tokina 16-50mm f2.8. Substantial and well made but not quite up to the over-the-top Nikkor and at a reasonable price for a good one. Tests I've seen show a reduced edge resolution at f2.8, which is to be expected but unlike those Sigma's, not a soft edge. And mid aperture it looks to be on par with anything else. So, my review is really for the whole fast standard zoom genre and how small the actual choice is, when it would seem to offer many. Score, for this Tamron, Price and image quality;10, handling; 6, overall 8 |
