New job...new lens

Ok...so I may have gone a bit made but I have finally treated myself to the lens that I have been watching for ages! I'm justifying it by saying that instead of being £1100 it was £175...so it would have been rude not to have had the last one!
I know I have been slacking, but this is from this evening in the garden. This is the first time I have had a go with the lens and so far I am seeing quite a big difference...in the weight of the camera if nothing else! Some of the pictures just look so much sharper and pick up so much more detail...I can instantly see why there is such a difference in price!
