Message: <blockquote data-quote="HokkaidoStu" data-source="post: 1442782" data-attributes="member: 504">That quote doesn't really mean much.In Japan the 150-500 is approx 50% cheaper than the older 80-400 was and about 20% cheaper than the Bigma. Why?If it is a 'professional' lens then Sigma executives must be smoking the same stuff as that woman in your avatar. Or something stronger. Sigma haven't made these lenses cheap out of the goodness of their hearts. There must be a reason for their price point.That's not to say it isn't capable of nice photos and I don't want to imply people who bought it have made some kind of mistake or anything. If I was in the market for a new big lens but couldn't afford to (or want to) pay double the price for say the Canon 100-400 or Nikon 80-400 I'd probably buy the Sigma and live with its limitations.</blockquote>
