Optics manufacturer Samyang has released a new lens simulator web app that allows you to see how certain lenses will affect the look of a scene based on sensor size and lens settings.

The web app creates a simulated scene using a cutout portrait of a woman as well as three backgrounds. By changing the sensor size, focal length, aperture and distance, the scene will adjust to show a simulated representation of what the image would like like when the shutter is pressed.

The web app is somewhat rudimentary, but its simulated representations do a good job of showing photography newcomers how crop factors, focal lengths, apertures and the subject’s distance from the lens can impact the look of an image. Samyang also includes an option to select on of its lenses to use as a preset of sorts to see what a given Samyang (also sold under the Rokinon/Bowen brands) lens will produce.

Both Canon and Nikon have lens simulators of their own, so this isn’t exactly an original idea, but it’s yet another option you can try out.
