i bought a pentax k-01 online and it came without a lens. so i bought two Vivitar lens from a guy. the two lens(Vivitar 28mm f2.8 and Viviar 80-200mm f4.5) were used and for a film camera. they both fit perfectly on the camera and show images. but... when there is a red flashing F-- on the bottom of the screen that wont allow me to take pictures. now i don't know a lot about cameras but i don't think that's normal. can anyone help me? please & thank you
