A new research note from KGI suggests that the new iPhone 6 models size difference won’t be the only thing that will set these the two devices apart. The larger 5.5-inch model is expected to support optical image stabilization, while the smaller 4.7-inch model won’t due to constraints in the production of VCM suppliers.
The 4.7-inch model will feature a motor similar to the one in the iPhone 5s, but will still see improvements in image quality that will include improved focus time and use power more efficiently than the design used in the iPhone 5s
Compared with conventional open-loop VCM, closed-loop VCM keeps records of focus points, enabling it to produce better quality pictures, focus faster and save power. Nonetheless, there are many factors that affect picture quality, and VCM specification is just one of them. Therefore, we believe overall picture quality of the 4.7” iPhone 6 will lead its peers’.
Apple is expected to unveil both iPhone 6 models this fall.
