Hi, I'll be taking photographs for the animal club in my school and I was wondering if my lens will be able to take decent shots. I have a 50 f1.8 and also kit lens with my 450d. basically i'll be taking shots of the animals posing with alphabets. the main purpose of the photographs are to be used for postcards which will go on sale in my school. each shot will consist of about 3-5 animals namely dogs and cats to form 3 words.
