Tamron SP AF 70-200mm F/2.8 Di LD (IF) MACRO
The optical quality of this lens is genuinely superb. What we have here is a flawed gem, a lens which fully capable of delivering excellent images, but also frustratingly capable of missing focus on that once-in-a-lifetime shot, either through misfocus or simply being too slow.
Low light shooters on a budget.
Photographers who depend on very fast autofocus.
