About - Tamron SP AF 17-50mm f2.8 XR Di II LD Aspherical IF

The Tamron SP AF 17-50mm f2.8 XR Di II LD Aspherical IF is part of the SLR lens test program at Consumer Reports. In our lab tests, SLR lens models like the SP AF 17-50mm f2.8 XR Di II LD Aspherical IF 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:
I have taken about a thousand pictures with it and have been completely satisfied. This is my first DSLR so I am a newbie but my buddy who is getting his masters in photography and has all professional equipment says it is a great lens. I found it pretty cheap as well, less than the 400s. I was prepared to send it back but had no issues. It seems to take great pictures inside and out.

The only con with this lens is hunting for focus in low light on rare occasions. I got it for under $250 as the result of a substitution for a generic lens that was out of stock. What a buy. I love it!

Comment:
This lens is great. You will see an immediate improvement in image quality over your kit lens (Canon anyway). The 2.8 aperture is nice on my older DSLR (Canon Rebel XT) as the high ISO output is poor. F2.8 at 50mm makes for nice portrait shots, with blurry backgrounds. Don't put poor quality lenses in front of expensive DSLRs!<br /><br />note: Tamron offered to clean inside for free.

Kit Replacement

Strength
SharpFast AFAccurate AFFast Aperture throughoutWide + some zoom on an aps-c sensor6-year warranty
Weakness
A bit pricey, but what glass isn't?
I bought this to replace my sony DT 18-70 kit lens on my Sony Alpha A300 and it's fantastic. It's AF is super fast and accurate. The sharpness is amazing especially when compared to the DT kit lens which is ugly in comparison. This lens has low CA and performs very well and IQ is great. It's probably not as good as the Zeiss 16-80 ZA f/3.5 lens, but this is a faster lens and costs less. It also comes with a 6 year warranty! You won't regret spending this kind of money on good glass!

Tamron 17-50mm f2.8 Lens for Minolta/Sony
01/10/2008
Strength
Fast f2.8 aperature. Solid build. Fast, quiet autofocus. 6 year warranty.
Weakness
No macro capability like the similar Sigma 18-20. No lens case included.
I purchased this lens after reading many positive reviews on web photography sites. The lens is well-built but compact and light. The f2.8 aperature will come in handy for indoor shots where flash is not allowed, which is the primary reason I bought it.The autofocus is fast and not too noisy. It zooms smoothly. 17mm on my 1.5 crop sensor results in a nice wide 25.5mm view. At the long end, the 50mm becomes 75mm, which is nice for a short telephoto view. It could be used for portraits at the long end but there are better choices for portrait lenes.Overall I am quite please with this lens and am glad I bought it.
