![]() Case 3 can also work well for birds in flight, though Case 6 can be better if the subject is not consistently within the frame.Ĭase 3 can be used with any AF area, though the smaller areas such as Expand AF area, Expand AF area: Surround and Zone AF give more control over where the camera is focusing. It also works well when photographing a bicycle race when you may choose to focus on a different cyclist in the peloton, or another cyclist may take the lead. This preset is suitable for different types of action where the subject suddenly appears in the frame, such as event horses going over a jump. If a new subject enters the focusing area the camera rapidly changes to focus on the new subject. Instantly focus on subjects suddenly entering AF pointsĬase 3 focuses instantly on subjects that enter the AF points.The downside of this case setting is that it is slower to find focus, so it is not suitable for subjects such as birds in flight. This will make the camera pause before trying to focus on any new subject that has appeared in the selected AF point or AF area.Ĭase 2 works well with all the AF areas, but tends to favour the smaller areas such as Expand AF area, Expand AF area: Surround and the Zone AF. The tracking sensitivity is set towards locked on. Case 2 can also work well for team sports where another player or the referee briefly passes in front of your intended subject, or when photographing a wading bird moving around where the line of sight may be blocked for brief periods by reeds or grass. This setting is most commonly used when shooting racket sports, such as tennis, where the racket – or even another player – may enter the frame in front of the player whom you want to be in sharp focus. Continue to track subjects, ignoring possible obstaclesĬase 2 is designed for subjects that may have objects appear in front of them, or where the subject may temporarily move away from the AF point.If you need to focus on a specific subject, using a smaller AF area will offer that control – providing you can keep the AF area you have selected consistently over part of the subject you want to be in focus. The camera will try to focus on the part of the subject which is closest to the camera. This means that using a larger AF area can often result in better focusing performance, especially with a subject that is fills the frame. It is well-suited to subjects moving at a constant speed, regardless of how fast or slow that is, and to those that can be easily followed by panning, or where the subject stays in a fairly constant place within the frame.Ĭase 1 works well with any of the AF areas, however in order to focus it requires contrast within the AF area. It is a versatile setting that will cope with a wide range of subjects. When you’re choosing which case setting you need, Case 1 is a good place to start. You’ll find more details below with the description of each preset. So each setting is based on tried and tested methods for focusing configurations which work.Ĭertain Case settings function most effectively when working with specific AF points or areas, so when selecting your case setting you also need to select the most appropriate AF point. #Canon mark iii wallpaper menu professional#However, it’s important to understand that Canon has worked carefully with professional sports photographers to understand how they set their focusing up – and Case settings is the result. You can tweak these parameters further no Case setting takes them further than a single adjustment from 0. The parameters control the way that the camera responds to movement including, for example, the subject moving away from the main focusing area, changes in speed and direction and even how the focusing point(s) follows the subject around the frame. These parameters are preset at different values for each Case setting, which is why your camera’s focusing performance changes each time you select a different one. ![]() Originally, each Case setting was made up of three controls to optimise the AF system: They also make it much quicker to reset your camera if the subject or type of movement changes – all that is required is a single change to select a different case setting and your camera is immediately optimised for a different type of action. This makes the focusing customisation process easier and much more accessible. These presets enable you to customise the autofocus settings to suit a particular subject or scene quickly – simply by selecting the most appropriate Case setting. ![]() #Canon mark iii wallpaper menu plus#More recently with the advent of the EOS-1D X Mark III the Case settings feature has been tweaked to offer four presets, plus an Auto option. Initially there were six cases, covering various types of action and movement. ![]()
