The iPhone 5S camera will get a small spec bump. Apple-watcher Rene Ritchie of iMore expects the 5S's iSight (rear-facing) camera to add a larger f2.0 aperture, which would allow more light to enter than the f/2.4 aperture on the iPhone 5. The result: Better image quality in low-light conditions. Apple wouldn't be a trailblazer here, however, as the HTC One already has an f2.0 aperture. The iSight shooter will likely remain at 8 megapixels, with Apple saving the big camera upgrade for next year's iPhone 6. As for the bargain iPhone 5C? Hopefully, it will retain the iPhone 5's very good camera rather than downgrading to an inferior shooter. A lot might depend on how aggressively Apple prices the iPhone 5C, however.
