Did not say better. Did not say worse. Just offering the OP an option that is far less expensive, that's all.
I have used a Summicron, a Summarit, and a Summitar. I could live happily everafter with either lens without ever wondering what I'm missing. Seriously. If you can't make good photographs with either of those lenses, then it's not the camera that's the problem, but rather the photographer.
