Re: Tamron 17-50 f/2.8 VC focus speed

Hello, i use the 17-50 non VC in both a 450d and my friend's 550d. It haunts for more than 3 seconds even more sometimes in low light. I do not know if this is just a body issue. Probabbly because the canon bodies does not have AF assist lamp (disregarding the blinding built in flash af assist ^^)
