iPhone 18 Pro: Do you need a variable aperture?

Apple just announced the iPhone 18 Pro with its first ever variable aperture main camera – f/1.48 to f/4. Sounds like a big deal. But once you factor in the size of the sensor behind that lens, the numbers look a lot less impressive. In this video I explain what aperture actually does, where the iPhone 18 Pro sits on the f-stop scale compared to a professional full frame camera and which situations the variable aperture actually helps with – and which it doesn't. #iPhone #iphone18pro #aperture ============================= Time Stamps: ============================= 00:00 Intro 00:16 What is an aperture? 02:40 Aperture range of iPhone 18 Pro 04:12 What are the benefits? 06:45 Apple Reference Image 📸 Gear I am using for my YouTube videos: Camera - Fujifilm XH2: https://amzn.to/3N6Svcp Lens - Sigma 17-40 1.8 https://link.amazon/B0321JqmG Key Light - Amaran 100d: https://amzn.to/47qSx4Z SmallRig Softbox: https://amzn.to/47hbDKE Microphone: Audio Technica AT 875R: https://amzn.to/3NGpFzC 32 bit Float Recorder: https://amzn.to/4rvVqsX Backlight - Aputure MC: https://amzn.to/3Jj6zNV Fill Light: Zhiyun M20: https://amzn.to/4o2pBqJ All of these links are affiliate links, so I may earn a small commission with each purchase made through them.
