Hi all, Was checking through ebay for a Tamron 28~200 minolta mount lens while found this: [URL]http://tinyurl.com/aqxch[/URL] It says the lenses are new, while the Tamron site says they should cost 500USD+, which made me a bit confused about the price difference. Is this ebay deal reliable? I never have bought anything from ebay so feeling a little helpless. Thanks in advance.
