Next year’s iPhones are said to come in a few varieties, at least three, with two of those models reportedly featuring a dual-camera setup on the back.

Now, according to another new research note from KGI Securities analyst Ming-Chi Kuo, Apple is planning an important change for the future devices that boast the dual-camera setup on the back. Kuo believes Apple will implement dual optical image stabilization for both rear cameras in next year’s iPhones. That would be a difference from the iPhone 7 Plus, which only features optical image stabilization in the wide-angle lens.

“We believe Apple will add OIS function to the telephoto CCM in order to enhance the selling points of next year’s new iPhone. We think photo quality and optical zoom range may both improve as a result. We expect the telephoto lens will be redesigned to support OIS in the telephoto CCM, with challenges likely coming from: (1) the need to increase the image circle of the telephoto lens, which will lead to longer calibration time and a more complex assembly processes; and (2) a redesign of the telephoto lens, as an increased image circle will result in degraded photo quality around the corners.”

Kuo also reiterates that he believes Apple will launch a 5.8-inch iPhone with an OLED display, and that there will also be a 2017 iPhone with a 5.5-inch display — both of which will feature a dual-camera system. Meanwhile, the 4.7-inch iPhone will reportedly feature a single-lens system on the back, which will also feature OIS.
