Francis- You obviously have figured out how to get brilliant photos at the wide end--don't give up on the narrow end! Vegas has lots of great characters and you need a little bit of reach to get them. Bring a medium telephoto, like the 70mm Ltd. and just play around with it, I think you'll be really surprised. Great for capturing faces and details you won't be able to get with a 35mm. Useful in nature, too! And it will challenge you a bit, giving you a different perspective to experiment with. I fell in love with the 70mm focal length on my trip to Italy and take it everywhere now. Especially when traveling with friends, I get intimate portraits from a distance they don't even know I'm shooting.
