              You never add the the score on Sony for
              1- More focus points 19 vs 11
              2- Continuous video focus
              3- Slightly more cross-type focus points 11 vs 9
              4- Supports 24p
              5- Takes 3D photos
              6- Video autofocus
              7- Better maximum light sensitivity

              These few points are indeed make the Sony A77 better than K5. As I had both camera + nikon D7000
