Our app involves using the camera to scan barcodes or QR codes, with a working distance of about 5 cm. However, we’ve noticed variations in the focus distance of camera lenses across different iPhone models. Currently, we mainly use two types of lenses: wide-angle and ultra-wide-angle. • For iPhone 13 and earlier models, we use the wide-angle lens. • For iPhone 13 Pro and later models, we use the ultra-wide-angle lens. We are not certain if this setup is correct since we don’t have all iPhone models to test.
There is a users have reported focus issues on his iPhone 15. We would like to ask if there’s a resource where we can find the minimum focus distance of different cameras in each iPhone model. This is to verify whether our current configuration is accurate. Alternatively, if such data is not readily available, could apple tam advise which camera should be used on various iPhone models for scenarios with a working distance of approximately 5 cm? Thank you!
