I have been recovering from surgery and I have way too much time on my hands to research my hobbies (Fishing-Photography-Gettysburg).
I have a Canon 60D with the kit 18-135. an old 70-300 and a 28 1.8 prime lens.
I noticed on Flickr many great pictures from one women with a 60D. They were taken with a Tamron 18-270 VC lens. I emailed her and she uses that lens 90% of the time on her camera.
Would the Tamron 18-270 give increase my photo quality over the 18-135 and the 70-300? Would love to carry one lens to cover almost that range.
I then would get a Canon 10-22 and I would have a nice range of lens. I see Tamron has a $100 rebate on this lens so for $400, it looks like a good buy. But one persons photos and likes doesn't make a trend.
Comments welcomed on the Tamron 18-270. Thank you.
While the Tamron is a competent lens, its not a great lens. I have one. I think what you are seeing is more a result of her skill as a photographer, and perhaps her post processing skills as well, rather than the result of the specific lens she is using. If she is that good my guess is she would get equally good shots from the lens you currently have ( within the focal range of course). Super zooms as a group tend to have poorer image quality than zooms with more limited focal ranges or prime lenses.
For a super zoom the Tamron 18-270 PZD (Model B008) is fairly well behaved. It has a lot of barrel distortion at 18mm, but its expected with lenses in this category. There is some chromatic aberration, but again for lenses in this category its fairly well behaved. Wide open it tends to be soft at the edges and fairly sharp in the center. The center and edge sharpness improves as you stop down, but the edges never really get razor sharp and the center still tends to be a bit soft at 270mm. Its has a slow f/3.5-f/6.3 aperture and often hunts a bit when attempting to auto focus in very low light. It doesn't have full time manual focus, but its focus motor is fairly fast and very quiet. There is a quite noticeable whirring sound and image jump when OS (Tamron's IS) is working.
My comments shouldn't deter you from getting one. The reach and flexibility of the Tamron makes its a very versatile one lens solution for many people. At the current price of $399 after rebate it's certainly a bargain, but don't expect miracles. If you are unsatisfied with the quality of the shots you are getting from your 18-135, the lens may not be the culprit.
As an addendum I believe that Tamron recently announced a new lens, the 16-300mm, an 18.8X zoom. That's quite a range, with a 35mm equivalent angle of view of 26-480 mm.
