View Full Version : Tamron 18-270mm PZD vs non

08-12-2011, 06:03 AM
Has anyone had the chance to do a side by side comparison with the newer Tamron 18-270mm PZD and the original non PZD version? I'm looking at optical quality. I know they have different glass groupings. Tried searching for articles but they only talk about the focusing abilities.

Would like to hear your experiences.
