Hyperphosphatemia is an electrolyte disturbance in which there is an abnormally elevated level of phosphate in the blood. Often, calcium levels are lowered (hypocalcemia) due to precipitation of phosphate with the calcium in tissues. Average phosphorus levels should be between 0.81 mmol/L and 1.45 mmol/L.
If the 'Full Frame' body was using a 24-70/2.8 lens and the 'APS-C' body was using a 16-50/2.8 lens, they would both be capable of almost identical images, but with an aperture of f/2.8 and a subject distance of 7 feet, the 'Full Frame' body would have a DoF of 0.5 feet and the 'APS-C' body would have a DoF of 0.66 feet, about what the 'Full Frame' ...
AF-C is continuous, when you focus on an object, holding it (half-)pressed, it will continue to try to keep whatever is in the focus areas in focus, whether you move or the subject moves, or you move the focus area to another subject.F-S is single, when you focus on one object and hold it (half-)pressed, it will keep the focus where it locked. This includes any movement of you/camera, and the movement of the subject. This is used for recomposing (once you lock focus, you can rotate the camera and the object will stay in focus).
