Tamron 28-75MM F/2.8 XR Di LD Aspherical (IF)

Review Date: Oct 19, 2008 Recommend? yes | Price paid: $300.00 | Rating: 8 

Pros: Sharp at 2.8, light weight, macro
Slow Noisy Autofocus, build quality, Glare,

After a lot of research and reading reviews I found this lens perfect for everyday needs I had. But may be either I had over expectations from reviews or nice photos from this lens, I wasnt impressed with poor color reproduction , slow noisy auto focus and no so sharp sharpness. But I was comparing it to wrong lens - 50 f/1.8 . AF, contrast, sharpness was not as good as compared to 50 f/1.8 At times photos would come good , at times they would be useless completely. I then borrowed my friend's canon 28-70 and compared photos side by side. 28-70 is built like a tank but it's AF weakness was revealed when I was snapping my 1 yr old son running around. tamron proved better in AF. It fares very well as macro, better than canon, MFD being only .33 m, which is very useful for me.
Canon hunted no less than tamron in dimly lighted areas. I might be wrong but 77mm thread should have been more useful.
at f/2.8 both lenses are same sharp at f/4 tamron shines marginally, at f/8 tamron is still leading.
Overall this is an f/4 lens. not that 2.8 is not usable but needs PP. Lastly doesnt look like a Professional lens but its the photos that matter.
