Tamron AF 70-300mm 1:4-5.6 Both Digital Film Canon Ef Mount LDDI w/ Filter Caps
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.
