Nice shots! The first one makes me a bit sentimental, because I recently cut most of the branches of a similar tree in my garden (entirely pink flowers, though). I hope it will have at least a few blossoms.
Second pic is most pleasant to look at.
Thanks. 500D is very convenient. You can screw it on any telephoto lens and shoot (no lens change, it means no dust into your camera.
Although it cannot replace a dedicate micro lens, it's good enough. Especially when you use it with 70-200 VR. you can still use VR and f2.8. What else do you expect? That's why I always carry it in my bag.
