I got a canon 400d with 18-55 lense, wanted to buy a multipurpose lense like the 18-200 range.
Offer from the shop are as below.... but i don't know which one is better, as in the "Di", "DC" thingy freaks me out.....
Tamron AF 18-250 F3.5-6.3 XR Di II D for Canon @S$607.00
Tamron AF 18-200 F3-.5-6.3 XR Di II D for Canon @S$375.00 (why is this so cheap?)
Sigma 18-200 F3.5-6.3 DC OS @S$730.00
