cheers mate, please say what you like about it and what can improved, so i can get better!

e/ yeah i think im gonna get one of them f1.8 50mils. ive just seen a 28-105 USM f/3.5- which looks pretty reasonable, does anyone know anything about one of them?
The 28-105 f/3.5 seems to be a very good lens but on your XSI it may will be too narrow for landscape photos.
