The most telling difference in the rear camera systems lies in the telephoto lens. Nothing Phone 3 deploys a 50 MP telephoto sensor with 3x optical zoom, while the OnePlus 13R pairs its system with a much weaker 8 MP telephoto and only 2x optical zoom. In practice, this gap is significant: a 50 MP telephoto retains far more detail when cropping or zooming further beyond the optical limit, and 3x already frames subjects more tightly without relying on digital interpolation. For portrait shots, wildlife, or any scene where reach matters, the Nothing Phone 3 has a structural advantage that pixel-peepers and casual users alike will notice.
On the main camera, the Nothing Phone 3's wider aperture of f/1.68 versus the 13R's f/1.8 allows more light to hit the sensor — a meaningful edge in low-light and indoor photography where every fraction of a stop counts. The selfie gap is equally pronounced: a 50 MP front camera versus the 13R's 16 MP means substantially more detail and cropping flexibility in self-portraits and video calls. The 13R's front aperture of f/2.4 is also slightly narrower than the Nothing Phone 3's f/2.2, compounding the low-light disadvantage on the front side.
Feature parity is high across both systems — OIS, 4K 60fps video, RAW shooting, phase-detection autofocus, and manual controls are all present on both. But the Nothing Phone 3 holds a clear and well-rounded camera advantage, with a higher-resolution telephoto, better optical zoom reach, a brighter main aperture, and a far superior front camera. For camera-focused buyers, it is the stronger choice across nearly every shooting scenario covered by these specs.
