In the focus setting, for experienced users, they could use the Servo + single-point focus mode to shoot. When shooting, first put the subject you want to shoot in the focus frame, press the shutter halfway to ensure that the camera is tracking, and then adjust the composition to the appropriate position and press the shutter. This method was not particularly useful in AI Focus. In addition, in the autofocus area, you can choose the entire area autofocus. The detection of the subject, eye detection, etc. are all selected automatically. There are detailed settings on the second page of the Servo-autofocus, giving four targeted focus scenes and the ability to customize the sensitivity and other settings. If you feel that it is troublesome, you can directly choose the more applicable Automatic. For example, in the R5 Mark II camera, thanks to the addition of the new processor, it had an intelligent AI algorithm function. In terms of focusing, based on this algorithm, it could greatly improve the recognition and tracking performance of objects. It could also further capture the movements and characteristics of the subject to carry out continuous tracking and focus, and maintain high precision of focus. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

It could focus manually at all times, and a slight dark angle could draw attention to the middle of the picture. Nikon AF-S DX35mmf1.8G lens was compact and light. SIGMAR Art 35mmf1.4 was very cost-effective. 2. ** 50mm fixed-focus lens **: Its angle of view is close to that of a single human eye and is called a standard lens. Using it to shoot characters could restore the real scene very well, and it could also achieve the effect of wide-angle and telephoto lenses.
