Tamron 17-50 brief review (non VR version)

I have been using this lens with my canon 550d.

Pros

• Good IQ - some say even better then the canon 17-55
• Useful focal length for a crop - wide to medium telephoto 
• Light weight / compact size
• Solid Build
• Much cheaper then canon 17-55

Cons

• Auto focus accuracy - especially in low light - is dicey
• LOUD auto focus
• Zoom ring swivels the opposite direction of canon lenses (left for wide)
• Slower auto focus

Comments

The Tammy 17-50 is the advanced amateurs tool, for creative photography. You need some patients to learn how to maximize the auto focus (aim for good light + contrast / color for best results)

This is not the best tool for fast grab shots at a wedding, but with skill and patients you can produce awesome images.
