Hi - I went to town yesterday to get a 25/105 lens, neither of the local stockists had one on the shelf and I ended up getting an EF-S 55/250 f4-f5.6 IS - it sort of fits the bill - it allows me to get close up pics without spooking the kids and still OK for general use.
I have ordered a 25/105L Lens off the internet but what I need now more than anything is experience and understanding, the camera knows more about photography than I do - I have also bought a 32 GB card so the camera will get a good workout over the coming months.
