I'm about to purchase a Nikon D5100 to replace a secondhand D40 I have just sold. I already own a 55-200mm telephoto and I'm debating on whether to accept the 18-55mm kit lens or go for either a 35 or 50mm Prime with my new camera. I don't shoot a lot indoors, nor many portraits. I like landscape photography but would consider a decent pancake lens in time. As an amateur, I appreciate the convenience of a zoom lens but have read more than a few articles on the use of a Prime lens to improve skills. So, my question is kit, 35 or 50?
