This particular version does not auto focus when past 200mm on the EOS Rebel T5. You have to go into manual mode for that portion of the lens to function properly. You can auto focus at a lower magnification and then zoom out, but it won't be as crisp as if you manually focused the subject.
Verified purchase: Yes | Condition: Pre-owned
Pros: weight, size, and the massive zoom range Cons: it is slow to auto-focus and often fails at fine focusing. Images are a little soft, especially at the ends of the zoom range.

Make sure you get the warranty on these Tamron B008 and B003 lenses! Only good enough picture quality for on-the-fly travel snapshots where you may need the zoom, this lens will fail before impressing: Noted for soft images in reviews, neither the Boo3 or smaller B008 will ever deliver award-winning pics. My B003 zoom barrel became impossible to turn at 18-30mm range after only 5 years of light use, and pampering care (never knocked or dropped and used in harsh 65 degree San Diego weather!). The mechanism eventually froze, shearing off the cheap plastic mount that holds the cog that makes zooming all happen. Possessing excellent mechanical and electronic skills, I disassembled the lens, epoxy-and-screw repaired the cog, examining the poor construction of this lens, and the lack of lock-tight on critical screws, which loosened; hey it's not a metal "L", Zeiss, Voigtlander or Leica, right? You get what you pay for. So if you're looking to buy a lens for under $300 and use a lens lightly for a year or two, to deliver blurry zoomed images, before the plastic moving parts crumble, this is it. Otherwise, go for metal, heavy and big - you will probably spend $1100, and get 10 years out of it to deliver razor-sharp images worth printing and winning contests. Summary? Some people don't know the difference between a hotdog and file minon. If that's you, use this lens, or even your cellphone! And please make sure the lens is covered with six months of pocket lint and dust so you have dark, blurry results. I replaced the crapped-out B003 with a new B008 on warranty and will toss it out as well after about 15,000 exposures. Just be warned, this is a disposable lens for disposable memories. I shoot all my award winners using my "L" lenses.Read full review
I purchased this lens for a Canon T2i. The main reason I bought this is because of the large range of focal lengths from 18mm to 270 mm, which covers a wide angle field of view to an advertised 15X telephoto range in just one lens. I also like that a user can choose to have automatic focus or manual focus with this lens. I found the auto focus to work quite well in most situations. The lens also has a user selectable Vibration Compensation, VC, mode. I've used it only with the VC mode selected. I believe this works quite well as I have taken some pictures just hand held that produced pretty good results. Naturally, the best result is still obtained using a tripod. I already had Canon lens that covered 18mm to 55mm, and another that covered 55mm to 250mm. I still consider both of these lens to be excellent. It's just convenient to have this capability in just one Tamron lens. But for dedicated close up or macro work, I still like to use Canon's excellent 60mm macro lens and a tripod.Read full review
This is a great travel lens. Very lightweight and small. The perfect lens to use when you don't want to lug the 2.2 lb Canon 70-200 f.28 around. It's not close to the same quality of sharpness that the Canon lensis,but the portablility and versatility will be worth it if you're traveling. It is not a low light type of shooting lens. Make sure while you're indoors your ISO is turned up. John F
