I'm obviously not a professional photographer but I love capturing those special moments of my daughter. After having our DSLR for about a year, this lense was recommended and I couldn't be more happy with it. It's the 50mm f/1.8. I love the crisp, clean images it produces. It's great in low light situations and I love the depth of field. It makes everything look so much more professional, without the professional price. I bought mine off of amazon.com for about $90. Can't beat that. Someday I do want the f/1.4, but this will do for now.
