Photography
Banding simulator
Explore how flickering light, shutter speed and sensor readout create bands in a photograph—and how panning tilts vertical lines.
Exposure Calculator
Find a starting exposure with Sunny 16, or balance ISO, shutter speed and aperture for a chosen light level.
Exposure Triangle
Explore exposure, noise, motion blur and depth of field with a running dog, a hummingbird or a landscape focused at infinity.
Field of View Calculator
Compare up to four focal lengths on full frame and see how much of the scene each captures, from 6 mm to 1200 mm.
FE Lens Diffraction Comparison
Compare telephoto reach, teleconverters and Super 35 crops, and see how aperture relates to a chosen diffraction criterion.
Super Zoom Lens Comparison
Compare how maximum aperture changes as you zoom, from the Sigma 20–200mm and Tamron 25–200mm G2 to longer and faster alternatives.
What Can You Photograph with Each Lens?
Explore photos by lens.
Choosing a Lens Kit — Where to Compromise
Build a Sony full-frame lens kit around what you shoot, and decide what you give up when one lens serves several purposes.
Diffraction Calculator
See an Airy disk on a Bayer sensor and calculate aperture from pixel size, sensor format and light color.
Image Circle & Aperture Diameter
Compare the image circle required by five sensor formats with lens entrance-pupil diameters, and explore an animated 3D light path.
