If the Snapdragon 710 chipset wasn't enough, perhaps this Oppo R17 Pro rumor can make you a believer - the dual camera will be upgraded with a dual aperture. Like the Galaxy S9 and, more recently the Note9, the R17 Pro shooter can reportedly switch between f/1.5 and f/2.4. Which aperture is used will depend on the lighting conditions. The f/1.5 mode will be used for low-light shooting and natural bokeh, f/2.4 for sharp photos in daylight. Oppo R17 Pro dual-aperture F1.5/F2.4#oppo #OppoR17 pic.twitter.com/rBUH0lS6Zh 📱 🖥️ 👦 👦 🔍 ...
