Join Ben Long for an in-depth discussion in this video Comparing autofocus and viewfinders, part of Advanced Photography: Medium-Format Digital Cameras.
- The autofocus systems in most full-frame…and crop sensor cameras are usually built around…a phase detection system.…Phase detection works great in low light…and is very fast.…For the most part, it has replaced…the previously dominant contrast detection system,…which is a bit slower and doesn't work so well…in low-contrast situations.…However, phase detection requires additional sensors…inside the camera.…That might be the reason that all three…of these camera manufacturers…decided to go with contrast detection…in these smaller medium-format cameras.…
When you're already worried about the size and cost…of your camera, reducing components might be a way…to make it cheaper and smaller.…Contrast detection works by analyzing the image…that is being captured by the sensor,…which means it shouldn't be such a good choice…for a camera with so many pixels.…50 mega pixels is a lot of data to analyze.…Right now, the state of the art…of autofocus for small medium-format cameras…can be summed up by saying that it's dramatically faster…
