Thanks everyone for all your advice and help. I ended up buying her a D3400 with 2 lenses in kit. She now says she wants another lens for portraits. She likes her camera, but she is now wanting to be able to have her portraits be blurred in the background (Is that Bokeh?). She mentioned someone told her a good lens would be a nikon af nikkor 50mmf/1 autofocus......would that be like the one gopher mentioned above 50mm F/1.8G?
This stuff overloads my mind. She has also been talking about lighting. That is a whole new topic though.
One other thing. This new camera she has problems getting it to take multiple pictures with one push of button (full auto, lol) is there a trick to that stuff?
Thanks again everyone for your help.
Blurred background is indeed "bokeh". Generally, you get "bokeh" by using a large aperture (e.g., f/2.8 or larger; remember that smaller f numbers are LARGER apertures) or by using a telephoto lens. In both cases, you will need some distance between your subject and the background if you want the background to be out-of-focus. Just how much depends on the f ratio and the lens focal length.
Nobody makes a f/1 50mm lens. Either the f/1.8 or f/1.4 50mm lenses that I listed are good lenses. Most diehard portrait photogs prefer a little longer focal length, though: something in the 85mm to 100mm or so is considered the "sweet spot" for portrait work. If you can afford it, the 85mm or 105mm would be better; if you can't swing that, the 50mm f/1.8 is plenty good.
nippr has you covered for the single/multiple modes of the shutter release (RTFM )
Probably wouldn't hurt to stop by Roberts Camera (downtown location) and peruse their used lens selection. Sometimes you can find good deals there. They'll be happy to talk lenses with you 'til the cows come home too!
