Wait If You Want Awesome Cameras
The iPhone 8 might include some unique camera features but the iPhone 7s and iPhone 7s Plus camera will still be great.
Apple tends to upgrade its cameras every year. The iPhone 7 shoots better pictures than the iPhone 6s, the iPhone 6s better than the 6, and so on.
Nothing is confirmed but it looks like there will be some improvements on the single camera lens coming with the iPhone 7s. In other words, it's probably going to take better photos and video than the previous model.
The iPhone 7s is expected to keep the dual camera setup the company debuted on last year's 5.5-inch iPhone 7 Plus.
At the very worst, you can expect these cameras to be on par with the cameras found on the iPhone 7 and iPhone 7 Plus. And they're still two of the best smartphone cameras on the market.
