Part 2 of Sigma 18-50mm f2.8 EX Macro vs Tamron 17-50mm f2.8 - Brick Wall test but this time instead of resizing the RAW DNG files, these are 100% crops via Lightroom 2 and SYNC crop function and exported as JPEG @80% quality

Approximate distance from lens to wall was around 40-55 cm. Guess the better macro function on Sigma helped
