Today I've had both around at a store to play with. And I'm going to buy the Nikon, because I've found something what I didn't like about the Canon at all.
It felt very cheap and unprecise when using manual focus with the kit lens, there also was some kind of play, where nothing happens at all when focusing. And as I'm going to use manual focus a lot, I will be better of with the Nikon.
Thanks for the opinion DWB anyway
