- 50D is a big jump that is sure to make you happy if you liked your 400D. You probably will be a lot more pleased.

- Softness has nothing to do with a camera body as long as we are talking of the same form factor. It is a product of opticals to great extend and then sensor size. May be they meant the kit lens that comes with it is soft but that is same with almost every kit lens except the very high end ones such as 5D mk II that comes with a kit lens that is "L" class.

I am sure you will be a lot happier with 50D especially if you already own a good set of high class Canon's products. If the deal is right, I would have no hesitation to go for it.

Lets see what others have to say for you.
