A rangefinder is a device that uses a laser to determine the distance to an object. It works by sending out a laser beam and measuring the time it takes for the beam to reflect off the object and return to the rangefinder.

How does a rangefinder work?
A rangefinder works by emitting a laser beam and measuring the time it takes for the beam to reflect back off of an object. The distance to the object can then be calculated based on the known speed of light and the time it took for the beam to return.
How does rangefinders work to help you take better photos?
Rangefinders help you take better photos by allowing you to accurately measure the distance between you and your subject. This information can be used to help you choose the right aperture and shutter speed for your shot, as well as to help you compose your shot. Additionally, rangefinders can help you take advantage of depth of field, which can be used to create stunningly sharp images with a beautiful background blur.
3 benefits of using a rangefinder
There are many benefits to using a rangefinder, but here are three of the most important ones:
- You can more accurately judge distances.
- You can find your target more quickly.
- You can save time and energy by not having to walk back and forth to check distances.
How to use a rangefinder for landscape photography
When shooting landscapes, using a rangefinder can be a great way to ensure your photos are in focus. Here are a few tips on how to use a rangefinder for landscape photography:
- First, make sure your rangefinder is properly calibrated. This will ensure that the distance readings are accurate.
- Next, choose a spot in the landscape that you want to focus on. It can be helpful to use a tripod when doing this.
- Once you have chosen your focus point, use the rangefinder to take a reading. The reading should be taken from the center of the lens.
- Finally, adjust your camera’s focus to match the reading from the rangefinder. This will ensure that your landscape photo is in focus.
How to use a rangefinder for portrait photography
A rangefinder is a great tool for portrait photography, as it allows you to accurately focus on your subject without having to take your eyes off the camera. Here are a few tips on how to use a rangefinder for portrait photography:
- Set the focus mode to single point AF (autofocus) and select the center AF point. This will ensure that the camera focuses on your subject and not on the background.
- If your rangefinder has a diopter, use it to adjust the viewfinder so that it is in focus.
- Position yourself so that your subject is in the center of the viewfinder.
- Half-press the shutter button to activate the autofocus and then take the picture.
