Camera Focal Length Visualizer
Explore how sensor size, focal length, and distance affect your photography
Choose from over 100 cameras and 50 lenses to visualize field of view, angle of view, and understand the relationships between sensor size, focal length, and shooting distance. Perfect for learning photography fundamentals!
Full depth of field calculator with real-time visualization. Adjust aperture to see how DOF changes. Subjects outside the DOF appear blurred. Explore photography concepts in the educational panel below, or quick-start with scenario presets. Yellow zones show acceptable focus, green shows sharp focus. Try different f-stops to see the effect!
Visualizations
Profile View (Side)
Vertical AOV: 27.0°
FOV Height: 4.80m
DOF: 7.6m - 14.7m
This diagram shows a side view of the camera's field of view. The camera is on the left, with lines extending to show the vertical angle of view. The depth of field zone is shown with colored regions indicating where subjects will be in focus.
Overhead View (Top-Down)
Horizontal AOV: 39.6°
FOV Width: 7.20m
DOF: 7.6m - 14.7m
This diagram shows a top-down view of the camera's field of view. The camera is at the bottom center, with lines extending to show the horizontal angle of view. Concentric circles show distance markers, and the depth of field zones are shown as circular bands.

Depth of Field Calculation
Step 1: Circle of Confusion
Formula: c = sensor_diagonal / divisor
Sensor diagonal: √(36² + 24²) = 43.27mm
Divisor (online): 1500
c = 0.029mm
Step 2: Hyperfocal Distance
Formula: H = (f² / (N × c)) + f
f = 50mm, N = f/2.8, c = 0.029mm
f² = 50² = 2500mm²
N × c = 2.8 × 0.029 = 0.081mm
f² / (N × c) = 2500 / 0.081 = 30954.3mm
H = 30954.3 + 50 = 31.0m
Step 3: DOF Near & Far Limits
Near Limit (Dn)
Formula: Dn = (s × (H - f)) / (H + s - 2f)
s = 10m = 10000mm
H = 31.0m = 31004mm
f = 50mm
H = 31.0m = 31004mm
f = 50mm
H - f = 31004 - 50 = 30954mm
H + s - 2f = 31004 + 10000 - 100 = 40904mm
H + s - 2f = 31004 + 10000 - 100 = 40904mm
Dn = (10000 × 30954) / 40904 = 7567.5mm = 7.57m
Far Limit (Df)
Formula: Df = (s × (H - f)) / (H - s)
H - s = 31004 - 10000 = 21004mm
Df = (10000 × 30954) / 21004 = 14737.1mm = 14.74m
Total Depth of Field
DOF = Df - Dn = 14.74m - 7.57m = 7.17m
