Start by defining your main use, whether you prioritize photos, video, or overall camera versatility. Evaluate the camera system as a whole, focusing on sensor size, pixel quality, aperture, and the imaging processor, not just megapixels. Look for strong software features like HDR, night mode, and RAW capture to flex your high resolution content. Consider display quality and battery life for reviewing and editing on the device, and check storage options, including internal space or microSD expansion, which helps you store many high resolution photos and videos.
