13P/M to the 14P/M or 15P/M is a noticeable upgrade. Both 14P/M & 15P/M main cameras have larger sensor and 48mp that pixel bin for better low light and picture quality. The 14P/M and 15P have 3x tele, while the 15PM have 5x tele. The blurry people are talking about is probably from the 15PM overriding the 5x tele with the main camera and digital crop when in low light.
