Explore how focal length, aperture and sensor size change your photos. Compare compatible lenses using published specifications and simulated optics, then choose glass that fits the way you shoot.
Depth of field, hyperfocal, blur disc, motion smear and exposure, from a thin-lens model. Real lenses and close-up results can differ.
Sensor sizes, mounts, blade counts and lens dimensions, straight from manufacturer references. Body details and internal lens geometry are illustrative.
Sample scenes use estimated depth maps and distance calibration. Focus and blur previews help explain relationships, rather than predict an exact photograph.
Lens-specific bokeh, sharpness, autofocus and aberrations need real-world testing. This preview does not measure those qualities.
