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

2875mm
Review Date: Feb 18, 2007 Recommend? yes | Price paid: $270.00 | Rating: 10 

 
Pros: Sharpness, Contrast, Price, Fast lens, Walk Around Lens, Weight
Cons:
Slow focus in low light, No USM

Like many who are going to read these reviews, at first, I was hesitant to purchase this lens. Questions that came up to mind were

The Good
1. Will it be sharp?
2. How soft will it be wide open at 2.8?
3. How does it compare to a Canon 24-70mm?

After using the lens for a few indoor and outdoor events
1. The lens is razor sharp, and I mean extremely sharp when compared to my 50mm 1.4. I am just blown away at how sharp this lens is.
2. Wide open with the Tamron is sharper than most lenses. My copy is very sharp at 2.8.
3. Comparing sharpness, the Tamron beats the Canon L lens hands down. Just check out the Pop photo's lens tests.

The Bad
In low light situations and lack of USM, the lens is slow to focus. I also wished Tamron extended the range of the lens to 24mm, but I'm assuming they designed it at 28mm for the sake of image quality.

Conclusion:
If you want a fast, sharp lens for 1/3 of the price of a Canon, then this is the lens for you. Real world example, I purchased all at the same time the Tamron 28-75mm, Sigma 500 DG flash, Gary Fong's flash diffuser, and a 300 watt sine wave inverter all for less than 1 24-70mm Canon L lens with money to spare.

Pros: cheap, will take pictures, solid build
Cons:
not sharp at all, worthless pictures for print, might work okay for web content

At the beginning of my photography, I was searching for a budget lens to start off with. I began with a Tokina 28-80mm on a canon 20D as my walk around lens. Pictures came out not at all sharp. We're not talking about RAW photos being edited here, but jpegs with in camera sharpening even when using a tripod. It would not be possible to salvage these photos photoshop.

I will now probably cave in and save up for the Canon 24-70mm which has top notch reviews.

After beginning and using this lens for so long, I began to think there was something wrong with my 20D. I then purchased a Tokina 12-24mm, and finally, that was an amazing lens in comparison--this lens is extremely sharp and contrasty! Guess the 20D is okay afterall.

Other lenses I use:
Tokina 12-24mm f/4.0
Canon 50mm f/1.4
Tokina 80-200mm f/2.8
