Here are a few new interesting review of 3rd party EF and EF-S mount lenses, from Photozone

• Sigma AF 70mm f/2.8 EX DG macro (Canon) review
• Tamron AF 18-250mm f/3.5-6.3 Di II LD AL [IF] macro review
• Tokina AF 100mm f/2.8 AT-X Pro D macro (Canon) review

The Tamron 18-250 looks like a great new version of the older hyperzoom. It looks actually useable! The two macro lenses from Sigma and Tokina add some good choices to the macro range.
