About - Tamron 18 -270mm f3.5-6.3 VC LD Asph Di II
The Tamron 18 -270mm f3.5-6.3 VC LD Asph Di II is part of the SLR lens test program at Consumer Reports. In our lab tests, SLR lens models like the 18 -270mm f3.5-6.3 VC LD Asph Di II are rated on multiple criteria, such as those listed below. Image quality: Image quality is based on tests of sharpness (modulation transfer function), geometric distortion, reflexes within the lens (flare), veiling glare index, vignetting, and macro performance. Modulation transfer function: This is a measure of lens performance and shows how well a lens reproduces object detail in the image it produces. Geometric distortion: All lenses have degrees of geometric distortion, which will depict straight lines as slightly curved. Two most common types are barrel distortion and pin-cushion distortion. These types of distortions are often seen in zoom lenses at both ends of the zoom range.

Comment:

This lens is great to cover nearly any situation that arises. But it's just not sharp enough for portraits of people. It's not fast enough for indoor shots without an external flash. But I carry a flash and this lens alone for most occasions. I use a much faster 50mm lens (equivalent to about 80mm)on my Canon T1i for photographing people.

How long have you owned it:

More than six months

Bottom Line

Yes, I would recommend this to a friend.

Comment:

This lens has replaced several different lenses.The trade off is considerable image distortion, especially at ends of zoom range (pin-cushion and barrel).The lens creep is getting worse as the zoom effort decreases over time.
