Apple Support's article:

iPhone camera basics – Apple Support

says:

"Zoom in or out

• On all models, open Camera and pinch the screen to zoom in or out.
• On iPhone models with Dual and Triple camera systems, toggle between 0.5x, 1x, 2x, 2.5x, and 3x to quickly zoom in or out (depending on your model). For a more precise zoom, touch and hold the zoom controls, then drag the slider right or left".

Hope this helps :-)
