hi everyone! I'd be getting a DSLR this coming September. Im choosing between these two: Nikon D90 or Nikon D7000. Do you guys have recommendations on what lens is best for each to exploit their sensor resolution. Please do indicate if they are expensive and or cheap so i could forecast my budget. Im into street photography, events, some portraits, nature and landscape. Third party lenses are welcome provided you really recommend them. thanks so much guys!
