- 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).

- What is AFM? The atomic force microscope (AFM) is one kind of scanning probe microscopes (SPM). SPMs are designed to measure local properties, such as height, friction, magnetism, with a probe. To acquire an image, the SPM raster-scans the probe over a small area of the sample, measuring the local property simultaneously.

- 1 AF-Lock. 2  AF stands for autofocus, and AF-lock is the easiest of these lock functions to use. 3  It's also the only one of the three that happens automatically when you take any photo. 4  AF-lock is activated by pressing the shutter button halfway. It can be useful to use FE-lock with reflective surfaces, which can fool flash metering, or with photos where the subject is not covered by a focus point. 2  AF-Lock. 3  AF stands for autofocus, and AF-lock is the easiest of these lock functions to use.

The TTL Flash System An obvious but none the less important switch is the Flash Mode Selector. There are four modes of flash operation with the SB-24/25: A, M, Lightning Bolt and TTL. The A makes use of the built-in flash sensor (not to be confused with TTL) for exposure.o TTL has taken all the calculations out of basic flash exposure. This is true for those who only want basic flash photographs. But I assume you bought this book because you want to take your flash photography beyond the basics by using flash as a creative tool.

DSLR Camera Basics In continuous-servo AF (AF-C), the camera will continue to focus if the shutter-release button is kept pressed halfway after the camera focuses. Because the camera continues to focus up to the moment the shutter-release button is pressed all the way down, this mode is a good choice for subjects that are in motion.F-C: No Focus Lock. If you change the composition after focusing in AF-C mode, the camera will refocus on the object that is now in the focus point, making it impossible to lock focus using the shutter-release button.

Canon EOS Canon also sold a manual-focus camera, the Canon EF-M, which used the same EF lens mount as the EOS cameras. It came with all the automatic and manual exposure functions but lacked autofocus. It came equipped with a split-screen/microprism focusing screen for precise manual focusing.he release of the 5D MkIII gave Canon the lead once again in this category; previously, its top-line cameras had 45 AF points, which led the industry until Nikon released its D3 and D300 DSLRs with 51-point AF systems.
