Mark is an avid photographer, but his current camera is an iPhone 6S. Leo says that the iPhone takes great pictures. He was thinking about buying a new mirrorless camera, but he's seeing just how good the iPhone is. Should he buy a new camera or upgrade to the best iPhone out there? Leo says that the iPhone 12 Pro Max would be a definite upgrade with a third super-wide lens and the ability to do computational photography. But Leo says that a mirrorless camera gives you more manual control. Lenses also give you control over depth of field. The glass is really what you're going to keep long-term. So it really comes down to what your style is shooting and whether you want to carry a camera bag or not.
Since Mark is shooting landscapes and other photos that require depth of field, Leo says that a Sony or Canon mirrorless camera will be the way to go.
And if you want to get a new phone, the iPhone 12 Pro Max or the Google Pixel 4a both have fantastic cameras.
