Tamron’s Vibration Compensation—Blur-Stopping Power With No Annoying Motion Delay In Your Viewfinder!
With the advent of the latest 15X zoom lens from Tamron, the pioneer of high power zoom lenses, the high power zoom lens has steadily evolved from a 7.1X to a 10.7X to a 13.9X and now to the world’s largest zoom ratio of 15X by combining advanced high power zoom design technologies accumulated by Tamron since 1992. The lens covers an angle of view equivalent to that of a 28mm wideangle to a 419mm ultra telephoto with just one lens, letting the user capture once-in-the-lifetime images of panoramic landscape images or close-up pictures of children smiling, without having to get too close to the subject and without having to change lenses.
Just like the rest of its (extreme zoom range) lens species the Tamron AF 18-270mm f/3.5-6.3 Di LD Aspherical [IF] VC macro (sorry, I had to repeat that again …) tries to provide it all but the continuously higher degree of generalization rather than specialization has a price – image quality. The lens had a bit of a hard time to deliver a good image quality on a very high resolution DSLR (EOS 50D @ 15mp)…
The AF 18-270mm f/3.5-6.3 Di II VC LD Aspherical (IF) MACRO undoubtedly represents an impressive feat of optical engineering, and Tamron has to be applauded for producing a superzoom that has significantly longer telephoto reach than its direct competitors without further compromising image quality…
Conclusion – Pros
- Remarkable 15x focal length range
- Impressive image quality in the normal to short telephoto range
- Excellent resistance to flare
- Effective vibration correction system, at least 3 stops benefit
- Reasonably compact despite the long telephoto range
Conclusion – Cons
- Slow and occasionally indecisive autofocus
- Geometric distortion across much of the zoom range
- Significant chromatic aberration at wideangle and telephoto (especially 270mm)
- Macro performance rather compromised (very soft at F6.3, focus shifts on stopping down)
- Uneven zoom action, zoom creep when not locked
- Slightly sub-par build quality
Like the other stabilized super zoom lenses, the Tamron 18-270mm f/3.5-6.3 Di II VC Lens, with a huge 15x focal length range and VC, is like two lenses and a tripod in the package of a medium-small lens (making it great for travel). And if you are willing to give up the ultimate image quality and wide apertures a multi-lens solution will provide for the convenience of a super zoom lens, the Tamron 18-270 is one of the top three Canon-mount models currently available right now.
