景深计算器
根据焦距、光圈、拍摄对象距离和传感器尺寸，计算照片中看起来清晰的距离范围。
景深计算器 gives you a faster way to work through practical calculation scenarios without rebuilding the same calculation from scratch every time. Start with 焦距 (mm), 光圈 (f-number), 拍摄对象距离 (米), and 传感器宽度 (mm) and use the live outputs to estimate 超焦距 (米), 远景对焦距离 (米), and 近景对焦距离 (米) in one pass. This page is built to help you compare scenarios quickly, validate rough assumptions, and move into a related calculator when you need a second angle on the same problem.
Use The Calculator In A Few Steps
Work through the inputs deliberately, then compare outputs instead of relying on a single scenario.
Scenario Checks
Use these examples to verify the behavior of the calculator before you run your own values.
What Users Usually Need Next
Keep the calculator open while you skim these answers so you can test the scenario that matters.
