Equivalent focal length = lens focal length × sensor crop × recording-mode crop. For a clear practical preview, each selected lens starts at its widest focal length; use the Zoom control to see how that lens tightens the shot. Lens-to-lens selections are not shown as a fixed-tripod distance comparison. Values are rounded to 0.1 mm. Fisheye distortion, focus breathing and physical camera distance are not simulated. Recording behavior and lens availability can change by mount, region, firmware and camera setting; verify compatibility with the manufacturer before purchasing.
