No.
After being in Florida over the holidays and taking a lot of night shots, I've decided to buy a 50mm 1.4. While on vacation, my son and I had a lot of lens between the two of us. We borrowed a 50mm 1.4 from a friend to take and we ended up doing a lot of shots with both the 50mm and my 20mm 2.8 on a D200 and D300.
FWIW, the 50 was the lens we ended up using the most.
