Thanks a lot JohnG. Just anoather point, if I use a 1.4xTC, I can still almost reach the same focal length and still have F5.6. If I use a tamron, It will be almost in the same budget.
But, how important is the IS to have at this focal length? For applications like taking photographs of nigh scenes at cities etc will it be of much use?
