I found the same as you. I went to the newer 28 X 300 as suggested by the Tamron rep and found it is great. My new lens focuses faster. That was my problem.

I have the Tamron 18-270 lens on my D7000 and am quite happy with it.

I was looking at buying that lens because of price and having an all in one lens. I think I will stay with my kit lenses now!

Don't bother trying the 16-300 you will have the same results. I sent mine back immediately for the same reason. I tried it on a D7100.

I bought this lens about 2 years ago and hardly ever take it off. It has performed beautifully for me ~ portraits, action, closeups, etc. There are a few little quirks you get used to, such as when zooming, I learned to stop extending right before it reaches the max extension. When extended fully, the photos tend be a little soft.

I have that lens and it works well for me up to about 200mm. You have to make sure that you are using a fast enough shutter speed for sure. I ordered the new Tamron 16-300 based on reviews and the fact that I like my 18-270 but ended up sending it back. It was no better and hand held was worse. I use it on a Canon 60D. Decided to buy the super sharp sigma 17-50 f2.8 and love it for wide angle landscapes and indoors. My next purchase will be a sharp 70-200 f2.8 or f4.0. At that point I will probably sell the Tamron 18-270.

I accidentally posted twice. Sorry.

I have removed my 18-270 and will give it to my nephew. I know use the Canon 18-135 on my 70D and the Canon 70-300.

I also tried the Tamron 16-300 mostly because it shoots slightly wider than the 18-270.
I found the 18-270 images to be sharper.
Returned the 16-300 and am keeping the 18-270 on my D7000.

I have an earlier version of this Lens. I have used it on a Nikon D70, D80, D90 and D7000. I also have the Trilogy set 14-24,24-70 and 70-200. I use the Tamron lense about 80% of the time. Mostly out of convenience. It's a great lens. If you're having issues with the lens talk to the people you bought it from. If you're still having issues see if you can contact Tamron Direct. I know they have representatives in the field.

Good Shooting

I bought the Tamron 18-270mm lens several years ago, for a cruise to Europe. It was a wonderful lens for the trip, was clear, and crisp. But, after the trip it was noticed to become a bit soft across its range. Tamron does supply a generous 6 year warranty with its lenses, so I sent it in for calibration/repair. In the repair statement Tamron supplied, it was repaired, a replaced internal lens group, alignment to my old 50D specs, and cleaned of manufacturing debris. When I tested the lens, in the 150-200 range it was almost "L" quality. To 270mm the lens was very good, as far as image quality. In the lower ranges it was also very good. It also focuses better, and maybe a bit quicker. I still use this on my 7D Mark II, when I'm just walking about on bright sunny days. I would send it in to Tamron for a calibration to your camera, and test and check. You'll get the lens back in about 5-6 days. You'll also get a email on how your lens was fixed, and what was wrong with it. I've found all the speculation on this forum does not help with a faulty lens. Just send it back to Tamron and get the real scoop. Keep in mind you own and shoot a Canon Camera, and all the Nikon speculation is just that. Canon is a totally different system. When reading a post that supports the Nikon mount, it is just a waste of time.

Here is a link to a YouTube page that explains one way of calibrating the D7000. The menu selections are at the 25% point.

There are other techniques, some require purchase of targets and other use yardsticks. Google should have them all

hi, the tamron 18-270 will be sharp only at F/8 to F/16 and between 35mm and 200mm, out this this lens is crap, will not work sharp

gypsylarry Loc: Lancaster, PA

I purchased mine about two years ago. I use it exclusively on my Canon 60d and the lens is "spot on" each and every shot. Perhaps you may want to see if it needs calibrated.

I have a Nikon D 40 and the tamron 18-270 mm lens. It is great. Maybe your sensor needs adjusting. I got rid of my kit lens since the Tamron does great. My buddy has a Canon with the Tamron 18-270 mm. His pictures are great. He is now up grading to the Tamron 16-300 mm. You should see his work
