Why Doesn't My Lens Fit the Whole Scene in Frame?

Likely causes

• Not checking the lens's actual angle of view before arriving. assuming a focal length is 'wide enough' without checking the actual angle can leave part of a scene cut off.
• Underestimating how much angle a close subject needs. a scene closer to the camera needs a wider angle of view to fit fully than the same scene from further back.
• Confusing diagonal field of view with what actually matters for framing. the diagonal figure most often quoted for a lens isn't the most useful number for judging whether a scene fits — horizontal and vertical matter more.

The fix

1. Check the horizontal and vertical field of view for your lens and distance before arriving at a location where reshooting isn't possible.
2. If the scene is close and won't fit, either back up if possible or use a wider lens rather than assuming the current one will do.
3. Judge framing decisions using horizontal or vertical field of view rather than the diagonal figure alone.
