Yes, go to Av setting for aperture control via camera or go to manual if you want to change both the Tv (shutter speed) and Av (aperture).
You have to got down to f8 up to f22 to have more DOF.
Play with the f11-22 to see if you can get more of the room in focus, albeit the IQ may suffer a bit (not that much though).

thanks. i'm just looking for a few nuggets to play around with until i get a chance to get down to the book store. right now the P and AV mode is enough for me to chew on.
just so i'm straight....the AV mode will allow me to control the aperture (dof specifically) while automatically choosing the right settings for everything else. and the P mode does what? becasue with the aperture ring set to A, i don't control the aperture anyway. its just automatic allowing me to use a manual lens?

Yes, that's the point of Av mode. Note you'll never get *infinite* DOF, and stoppng down too far (like to f/16 or beyond) rarely does you any favors in terms of overall IQ.

P mode is just the regular automatic exposure setting - it chooses all settings for you. It's more or less just like the Green mode, except it also lets you override more settings - eg, choosing your own WB, or applying exposure compensation.

i know the basics....i know (from reading only) that the aperture number determines how open the circle in my lens is. the lower the number, the more open it becomes and the higher the number the smaller the hole becomes, i think. i also read that for shooting in aperture mode if i use a small number, that i will get the foreground in focus and the backgorund a little blurred. a higher number would get everything in focus. does this sound right?

so when i put this lens on (f1.4), what mode do i shoot in and will the other settings such as iso and shutterspeed automatically be determined?

all i want to do is be able to blur the background and/or get everything in focus when ever i want to and know how i did it. any help is appreciated. i still have to by a book and read a little but i haven't gotten to the store yet.
This may help a bit before you get to the bookstore: Aperture, shutter and ISO value | Camera Simulator.
Read the intructions and move the sliders to see what your camera is doing.
