Tamron LD LD A14 18-200mm f/3.5-6.3 Di-II XR Aspherical IF Canon Digital Film

Just works as it should be, no problem at all. Crispy, Accurate AUTOFOCU. I have tested in on my Canon 350D and Canon 30D Digital SLR, Eos 100 Film SLR, there is NO compatability problem appears even I tried it at Wide or Narrow Aperture.
