Hello guys,
I would like to ask your professional advice. I'm planning to buy a lens and I have 3 choices.
1. Sigma 18-200mm F3.5-6.3 DC OS
2. Tamron AF28-200mm f3.8-5.6XR Di Aspherical IF
3. Canon EF-S 55-250mm f/4-5.6 IS
Which one should I buy? based in your experiences what's the best lens for me.
Thank you....
