Optics Lab
Master the physics of your glass.
A comprehensive suite of advanced calculators for depth of field, hyperfocal distance, and macro photography. Calculate the exact optical boundaries of any lens and sensor combination.
Depth of Field
Calculate critical focus and sharpness for any lens and sensor combination.
Comprehensive Inputs
Calculate critical focus using your exact focal length, aperture, subject distance, and specific sensor type.
Distribution Graph
Visualize your sharpness with a graphical bar showing the exact percentage of focus falling in front and behind your subject.
Infinity Support
Flawlessly calculate depth of field and front distances even when your subject focus reaches true infinity.
Precision UI
Dial in your exact parameters seamlessly using our rapid manual entry and precision distance wheel.
Hyperfocal Distance
Maximize your depth of field for flawless landscape photography.
Landscape Mastery
Calculate the exact optimal focusing distance required to keep everything razor-sharp from half that distance all the way to infinity.
High Precision Mode
Enable stricter Circle of Confusion (CoC) parameters tailored for the demands of modern high-resolution digital sensors.
Macro Lab
Specialized tools for extreme close-up photography and magnification.
Extension Tubes
Take the guesswork out of macro. Instantly calculate the unavoidable light loss and your new magnification ratio when attaching extension tubes.
Reverse Lens
Master extreme close-ups with dedicated calculations specifically designed for reverse lens mounting techniques.
Sensor Visualizer
Get a highly intuitive graphical representation comparing the physical size of your magnified object directly against your camera’s sensor dimensions.
