I use ultra-wides for property photography. This one is the best I have used so far. Compared to the Tamron 15-30 SP G2, the 17-35 is consistently sharper and far less subject to misfocus. The G2 and the earlier iteration of Tamron's 15-30 misfocused about 5% of the time while using live view. This required me to verify the focus of every single shot I took. The same is true of Nikon's aged 14-28 f2.8. The autofocus speed of the 17-35 is somewhat slower than the 15-30 G2, but it exhibits far less hunting and is more accurate with the D750 and D850 Nikon. The lighter weight and ability to use normal filters is a huge benefit. I hardly notice the shift to f4 from f.2.8 at the long end of the lens. One additional bonus is the 17-35's superior ability to suppress haze ... MoreI use ultra-wides for property photography. This one is the best I have used so far.

One additional bonus is the 17-35's superior ability to suppress haze around bright windows and highly reflective surfaces. If you need the extra width of the 15-30, I suggest you pick up a 3rd party 14-15mm to cover those occasions when you need a bit more coverage.

I purchased this lens based on favorable reviews, and have been pleasantly surprised. I agree with most of the reviews - the lens is not heavy, feels pretty solid, has a good feel/grip. It attaches to my D610 nice, not too tight, and releases easily. I like that Tamron made it a 77mm lens so my filters can work with my 24-70. I find it to be slower to focus than my other lenses, but that's not a real problem, images are sharp. The lens hood is large I suppose by necessity, but not obnoxious. I think distortion at the wide end can be minimized with proper technique; sounds correctable in post, but I haven't spent much time with that. I'm looking forward to using this on a trip to Death Valley and other parks this spring. I'm still getting used to WA, it's a different ... MoreI purchased this lens based on favorable reviews, and have been pleasantly surprised.

I don't see anything really negative about this lens, it's fun to use, and you learn to see differently thru it.

I have quite a few AF Nikon fixed focal length lenses, both old and newer versions. My first Tamron Di lens was the SP 85mm f1.8, purchsed for the image stabilization feature. Asside from the bonus of stabilization, the optical quality was noticably superior in every respect in reference to the Nikkor 85mm f 1.8. My kit now includes the Tamaron 35mm, 85mm, and most recently the 17-35 Di series lenses. There may be lenses that perform marginally better on a test bench, but in real worldapplications there are zero image quality or functional issues. I purchased the 17-35mm to fill the wide angle requirements below 35mm. I was not expecting the zoom to be as sharp at 35mm as the FFL 35mm but it is very close. I don't have a highly rated 16 or 17mm FFL to compare it to ... MoreI have quite a few AF Nikon fixed focal length lenses, both old and newer versions.

I don't have a highly rated 16 or 17mm FFL to compare it to but at 17mm the performance is very good; as would be expected it is not quite as good as it is at 35mm. Used on a Nikon D850: amazing optical performance, fast focusing, solid construction, attractive design, and value priced.
