>>3555940buy used. don't spend more than $700 on the body.
the kit lens is okay but its slow, generally sharp in the middle of the image and doesn't do macro well.
you can pick up some nice vintage lenses if you need something cheap after blowing $700 on a camera. Check out the 50mm f1.4 vintage lenses (Pentax, Minolta, and Canon made some of the best in these classes) for about $110 with an adapter.
Your first lens should be one of the following:
85mm f1.8 (For portraits)
35mm f1.8 (for walkaround/portraits/street/landscape)
55mm f1.8 (same as above)
Tamron 28-75mm f2.8 (great all-rounder for under $1000)
Sony 90mm f2.8 Macro (extremely sharp at all apertures
Sony 50mm f2.8 Macro (same as above but closer working distance)
Avoid:
24-70 f4
28mm f2
85mm f1.8 Zeiss
35mm f2.8 Zeiss
Cheapest, most useful lens you can get is the 35mm f2.8 Rokinon for ~$200. Great little lens. Pocketable and sharp. The 50mm f1.8 is decent but you're better off saving the money for either the 50mm f2.8 macro or the 55mm f1.8 zeiss, which are much much sharper and will resolve up to 61 megapixels easily.
