Well i've been kinda jumping around the forums and such and found a site that compares lens's, cant remember which.
I've been wanting a lens that compliments my 55-250mm 4-5.6 IS and from what i can tell that the Sigma 18-50mm F2.8 EX Macro would be a good lens to have.
Especially since i have spotted a few used ones going between 100-200$. I think that is a good price for this lens.
Im only a hobby photographer.
shooting a canon rebel 300d already have the nifty fifty, and just got the 55-250 IS.
I think it would be nice to have the lower range of the 18-50mm sigma
