So I think I have narrowed it down to these 2ish Tamron SP AF 28-75mm f/2.8 XR Di LD Aspherical (IF) , sigma 17-50mm f2.8 os hsm etc and maybe the equivalent is sigma of the 28 75 and the tamron 17 50 which ever I can find at the best price and value for money . I'm open to suggestions or even lenses for shooting indoors garden kids family Etc
