Digital booths
A crop factor changes framing, not the lens focal length
Compare sensor formats without misdiagnosing a booth composition as a lens change.
A replacement camera with a smaller sensor can make the same lens appear to frame more tightly. The lens has not changed focal length; the sensor records a smaller portion of its projected image. In a fixed photobooth, that difference can cut off shoulders or reduce the space around a group even when the camera body fits the same mount.
Separate focal length from recorded view
Nikon’s DX/FX guide explains that a smaller sensor captures a narrower portion of the image circle; its DX system example uses a 1.5x crop factor relative to a 35mm frame. The numerical factor is format-specific and should not be generalized to every camera. Focal length remains a property of the lens, while sensor format determines how much of the image is recorded.
Recheck the full booth composition
Keep camera position and lens zoom fixed while comparing format changes. Photograph the same marked standing area and compare the actual frame edges, not only a viewfinder preview. Check headroom, elbow clearance and the nearest and farthest guest positions; a tighter recorded view may need a different lens or camera distance, each of which affects perspective or depth.

Avoid the sensor-size shortcut
Do not assume a crop factor means more optical reach or a sharper portrait. It describes a framing equivalence, not a change in lens resolving power, subject distance or perspective. Record body format and lens focal length in the booth setup notes, then make framing decisions from the sample image at the final print-strip crop.
