Browsing in a camera shop while on holiday a few months ago I came across a Tamron 90mm 1:1 macro on display at a very low price. I have always thought I should have a macro lens so on the spur of the moment I bought it. The shop assistant went and got the box for it and packed it all up for me. As I was aware there were several versions of the Tamron when I got home I googled the description on the box to find it was the older version that had no VC. However when I looked at the lens I discovered it was the latest version with VC. Luckily the shop is in another city and I don't feel obliged to tell them they got their stock and possibly pricing mixed up. Ended up with a demo lens at approximately 40% of normal retail.
That was all a few months ago and have only just got around to having a play with it. At this stage just close ups rather than true macro. Happy enough that I have dragged out my now seldom used flash to try and find some smaller live subjects to test it on.
