FAQ:
Q: What is the best back focus chart app?
A: Distant Blue has created an app that gives you a perfect back focus chart download. And the app is appropriately called just “ Focus Chart .” It’s only available on the App Store, so you’ll need an iPhone or iPad to download it. It’s completely free, so you can use your phone as a focus chart on your next project.
Q: What is the best length for back focus?
A: Let’s get one thing out of the way: back focus is a property of optics, not cameras. That being said, 55mm is an industry-standard length of back focus for many optical correctors and focal reducers.
Q: How do I measure back focus?
A: Back focus is most commonly measured from the flat edge of the corrector/reducer facing the camera, not including the threads on the corrector/reducer. You can use a tape measurer (or more ideally, a pair of calipers) to measure back focus. See the diagram below: My Camera Says I Need 55mm Back Focus. Is This Correct?
Q: How do you use a focus chart?
A: You start by putting the chart in front of your camera. It should fill up the entire frame. From there, you can still if your camera lens has a consistently sharp focus across the frame or if it becomes blurry in certain areas. You can rack focus until it’s just the way you want it.
