One of the very unique zoom lens ever made by any company is the Sigma's 50-500 range super zoom. No company to this date has dare to make a competitor for this Bigma.
Here is one I found on ebay that might be the original idea!
Do you know of anything close in this range? i.e. from almost neutral (50mm) to a super tele?
