Thanks for that buddy, it was really helpful. At first i want a cheap ish entry level camera and down the line i will get something better as i will not really be blowing photos up to poster size. In fact the biggest will probably be A4 for now so the 6MP should be ok in the D40.
I am just worried about the features as i want to be able to play and learn about the different functions that a camera can do and what impact it will have on the photo if you change something. Reading about it is one thing, but doing it is where you learn.
I will mainily be taking pictures of cars and things close up, however the odd long distance photo will be in there too, but not all the time. I may be doing modelling shots too for friends as i am quite good at that, as well as band shots and artist shots, so a decent wide angle lense is needed and some filters too.
