As the adjustment spindle could be quite long in lenses with long focal length, focusing speed is slower than with shorter focal length lenses. Therefore those lenses do have often the possibility to limit the area in which the lens should focus on. In most cases, you can choose between total range, close distance, and far distance. This limits the adjustment spindle and makes focusing faster. Are you shooting for example wildlife, which you are not able to approach close, you can choose only the far distance setting. The lens is then able to focus faster. This possibility is, as already mentioned, only available for long focal length lenses and is limited to three settings.
OM-D cameras have the possibility to set the AF limit via software, which can be used for any lens. You can save three different settings, which you can use at any time. How to use this function I would like to show you as follows.
1 The settings for AF limiter are located in the Menü A (in case of E-M1X it is A3, in case of E-M1 Mark II/III it is A1) Here you can make your basic settings.
2 To make the basic settings press the arrow keys three-time right. Then select one of the three settings and press the arrow key right again.
3 Use the arrow keys to adjust the close and far limit. As soon as you have finished press “OK” to confirm the settings.
* Please keep in mind those values are not exact values. Therefore you can ignore the value behind the comma.
Here you also can change your settings while you are shooting. However, this is quite complicated and is not fast enough. Therefore it makes more sense to program a function key. Then you have direct access to the limiter. I personally use the L-Fn button of the Pro lenses. In case you don’t have Pro lenses or the F-Ln button is already used for something else you also can use another function button.
4 The fastest way to reach the button settings is the Super Control Panel. Just press “OK” and choose the gear wheel.
5 Here you can directly program the function keys. Choose your favorite function key and select AF limiter.
6 Pressing the selected function key allows you to switch the AF limiter on/off. To switch between your three basic settings just press and hold the function key. The selection Menü opens and you can select one of your basic settings.
I hope this tip helps you to make better images. I’m happy when you leave a comment.
