Thanks Leighton,
I just have the standard 24-105 lens which comes with the nikon package, my mate didn't know how to zoom as it was his first time using a dslr with a zoom lens. The key is to take your photos on the largest setting possible that way you can crop right in and not loose too much quality, it's got nothing to do with blowing the picture up, but cropping in nice and tight and composing your shot on your computer at home. My camera has 12 megapixel so the quality is good.
