Tamron 17-35mm f2.8-4 Di LD Aspherical

sp-af17-35
Review Date: May 6, 2005 Recommend? yes | Price paid: Not Indicated | Rating: 7 

 
Pros: Nice built, cheap, sharp pictures
Cons:
Purple fringing

I bought this lens after reading some reviews comparing it with Canon 17-40L. I already have Tamron 28-75 F2.8 and really love this one, so I think Tamron 17-35 will have the same quality.

After some tests, I found that it suffers quite badly from purple fringing, especially if the background is bright. Other than that, it can produce sharp pictures. My Tamron 28-75 lens doesn't have this CA issue.

Pros: Nicely built, white coating, fast AF, internal zoom, internal focusing, lightweight.
Cons:
Picture quality is not sharp, color is not brilliant. Price is too expensive.

I bought this lens after reading all the good reviews from this forum and dpreview. My first problem is backfocus, so I had to send it to Canon Service. This doesn't fix the backfocus issue, so re-sent it second time. This second time the backfocus issue is resolved. However, I notice the lack of sharpness, color saturation when using this lens.

I will sell this lens and change it to other brand, most likely Tamron zoom lens. I had very good experience with Tamron 28-75 F2.8 Di, it is sharper and produces more accurate/brilliant color compared to this L lens.


 
Tamron 28-75mm f2.8 XR Di Zoom AF

28-75mm
Review Date: Oct 20, 2004 Recommend? yes | Price paid: $360.00 | Rating: 10 

 
Pros: Very Sharp, cheap, lightweight, lens cap can be removed while the lens hood is mounted, excellent color and contrast reproduction
Cons:
None

I was reluctant intially to buy non-Canon lens, but after reading all positive reviews about this lens, I took the plunge, and I glad I did. This lens is razor sharp.. I mean really sharp, even at 2.8. Color reproduction is excellent, better than Canon, Tamron color is more natural. Pictures also have more contrast and saturation to it. The lens is also useful in low-light condition due to its constant aperture (f2.8).

I wish I've bought this lens when I first had my 10D. I've bought 50mm 1.8, 28-80 F2.8-4L, 17-40 4L, 70-200 4L before buying this Tamron lens. I could've saved $$$ by buying this lens in the first place. I've sold my 17-40 4L and 28-80 F2.8-4L. And I seldom use my 50mm 1.8 nowdays..

Tamron 28-75 F2.8 is mounted on my 10D about 90% of the time!!
