The rear camera systems share a 50 MP primary sensor and OIS, but the configurations diverge meaningfully from there. The Oppo A6 Pro 5G pairs its main lens with a 2 MP secondary — effectively a depth-assist sensor with limited practical utility. The Galaxy A36 5G fields a proper triple-camera array: 50 MP main, an 8 MP ultrawide, and a 5 MP macro lens. That ultrawide alone is a significant real-world differentiator, enabling landscape shots, group photos, and tight-space photography that the Oppo simply cannot match. The macro lens adds close-up versatility as well.
Aperture is the other major gap. The A36 5G's primary lens opens to f/1.8, compared to the Oppo's f/2.4 — a full stop and a half wider, meaning it admits roughly 2.5x more light. In low-light conditions, this translates directly to brighter, less noisy images without relying as heavily on software processing. On the front, the dynamic reverses slightly: the Oppo offers a higher-resolution 16 MP selfie camera versus the A36 5G's 12 MP, though the A36's front aperture of f/2.2 is wider than the Oppo's f/2.4, offering a modest low-light edge in selfies despite the lower pixel count. Video capability tops out at 4K/30fps on both devices, with an identical feature set for manual controls, HDR, slow-motion, and autofocus.
The Samsung Galaxy A36 5G is the clear winner in this category. The combination of a wider main aperture for superior low-light performance and a genuine ultrawide lens gives it a versatility and image-quality ceiling that the Oppo's dual-camera setup cannot match. The Oppo's higher selfie resolution is a minor consolation that does not tip the balance.
