After looking at pictures on this site, http://www.pixel-peeper.com I have bought the Tamron 70-300 f4-5.6Di LD until funds allow the purchase of the 70-400G

The 28-300 may as well stay on the 7d so that Jan can use it when she wants, she normally uses her Fuji S9600, but is now spending more time with a DSLR..........
Will post pictures after I have given the lens a whirl........
