Considering of getting a longer range lens with macro capabilities... Narrow down the search to the follows... Need some advice...
Tamron AF70-300mm F/4-5.6 Di LD Macro 1:2
Sigma APO 70-300mm F4-5.6DG Macro
Seems like Tamron is slightly better:
- Lighter weight (435g VS 550g)
- 13 elements and 9 groups VS 14 elements and 10 groups
- Smaller min aperature (F32 VS F22)
The question is that is there anything more to look out for? Not too sure which one AF faster etc... What's the approx price out there for these lens?
