There are many people who are interested to know if both the iPhone 6 and iPhone 6 Plus have an optical image stabilization, not just a digital image stabilization.
According to the official iPhone 6 specs on Apple’s website, the iPhone 6 Plus iSight camera is the only one who has an optical image stabilization mechanism. So therefore the iPhone 6 (non plus version) does not have an optical image stabilization, as mentioned in Apple’s website, and I quote:
“Optical image stabilization (iPhone 6 Plus only).“
I already see people thinking about getting the iPhone 6 Plus for this specs along. This can vastly improve the low-light capabilities of the camera when shooting at slow shutter speeds, and also help in getting sharper images. A useful camera feature that exists on competing models, and unfortunately is missing on the iPhone 6 (but does exists on the iPhone 6 Plus model).
