Metal Silvery LightMate Area 2S + OV-X1 17-degree Film Camera Light Meter High Precision Chargeable Exposure Meter

Improvements:
1. Add a "magnetic filter interface" that can install filters such as incident light measuring spheres.
2. Update to "2nd generation Pinball Anti loosening Shoe Seat".
3. The metering button has been updated from a two-segment design to a simpler and more user-friendly "single-segment button".
4. Add a "vfPort interface" for installing accessories such as a metering viewfinder to improve the accuracy of the metering area.

Description:
- It is a light meter or exposure meter used to provide exposure parameters for film cameras.
- Your camera needs to be able to manually control the aperture and shutter speed.
- Based on your shooting creativity, use the aperture and shutter value provided by the exposure meter to create.
- The LightMate Area is a 17° area light meter equipped with a bright optical metering viewfinder. The 17° metering angle provides a user experience similar to a point light meter, allowing for quick and accurate metering of the image through the metering viewfinder.

FAQ:
Q: What is the function of the viewfinder of the LightMate Area 2S light meter?
A: The metering viewfinder allows for real-time viewing of the current metering screen, allowing for more accurate metering, much like using a digital camera to see specific metering positions on a display screen.
  For example, in a metering viewfinder, align all areas of the center line with the model's face, and the metering result will be the metering result of the model's face, unlike without a metering viewfinder, which requires estimating the exposure area for metering. The exposure results will be displayed on the display screen outside the metering viewfinder.

Q: What is the difference between the 17 degree metering angle of LightMate Area 2S and the 30 degree ratio of Lite 2R/2S?
A: The 17 degree metering angle of Area 2S is 50% narrower than the 30 degree metering angle of Lite 2R/2S, allowing for more accurate and concentrated metering of a certain area of the image. It is precisely because the metering angle is narrower that the LightMate Area 2S is equipped with a metering viewfinder with a 17 degree metering area within the metering frame to observe the desired metering image.

Q: Can the metering viewfinder of the LightMate Area 2S meter be disassembled? Can it be used as a viewfinder for a camera?
A: It can be disassembled because Area 2S has a vfPort viewfinder interface. The OV-X1 viewfinder cannot be used as a composition viewfinder because its image is circular.

Q: What about the metering accuracy of the LightMate Area 2S light meter?
A: The metering lens of LightMate Area has been designed, simulated, and validated through testing. Area can provide a metering angle of 17 degrees, with a metering range of EV0 ~ EV20, and a metering accuracy and resolution of +/-0.1EV. During production, the light meter will align the sensor and lens optical axis to calibrate assembly errors.
  The aperture, shutter speed, and ISO gear resolution of an Area 2S light meter can reach 1/3 gear. At this point, the limitation is no longer the light meter, but that most cameras can only step in full gears such as 1/125 or 1/500. The 1/3 gear of the light meter can help you understand the deviation of the current exposure result compared to the entire gear, so that you can have a clear understanding when determining exposure parameters.

Q: How to simply test the metering accuracy of LightMate Area 2S?
A: We suggest using a large area of solid color background to simply compare and test the metering accuracy of the Area, which can minimize other sources of interference. For example, the grayscale surface inside the Area packaging box can be used to test against other reflective professional photometers. When conducting testing, it is necessary to ensure that the current environmental light source is a stable pure artificial light source, and then use Area and other professional light meters to measure the gray surface of the packaging box multiple times at 15cm, and then compare the differences.

Q: Why is there a difference in the metering results between the LightMate Area 2S meter and my camera?
A: When a LightMate Area 2S light meter is installed on a camera for comparative testing, there will be various errors that will cause the test results to be different from the camera's metering results, which is a situation that can occur with any reflective external light meter. These errors come from: the optical axis of the light meter is different from the camera lens, the field of view angle of the light meter's light meter lens is different from the camera lens, the metering mode of the camera is not exactly the same as the light meter, and the ISO calibration of the camera is different from the ISO of the film.
  Therefore, we do not recommend using digital cameras for comparative testing.
  Digital cameras usually use the lens for metering (TTL), which is currently recognized as an extremely advanced reflective metering method and is not limited by any parameters of the lens. Any brand of metering instrument manufacturer will not guarantee that you can use their metering products to measure results consistent with those obtained through camera lenses.
  In actual shooting, the Area 2Slight meter provides high-precision 1/3 level exposure parameters, but the camera's lack of such resolution shutter and aperture levels can also result in errors in the final exposure. The Area 2S metering watch comes with a metering bypass type metering viewfinder, which is not in the same optical path as the metering lens. These two optical paths form three parallel optical paths at different positions with the camera lens, which will introduce parallax error. Even if there is parallax in the metering viewfinder of Area, it still has significant advantages compared to a metering meter without a metering viewfinder.

Q: How will I use the LightMate Area 2S metering meter correctly?
A: The LightMate Area 2S light meter features a 17 degree metering lens and metering viewfinder, allowing for small area metering compared to 30 degree or wider angle metering meters. When measuring light in a 17 degree area of the screen, the light meter only provides the correct exposure result for that area, and does not guarantee the exposure result for images outside the area. If you are using a camera lens with a focal length of less than the equivalent 135mm, it is best not to use this set of exposure parameters immediately after metering each area. You need to metering multiple areas of the screen and then choose the appropriate exposure parameters based on your creativity. For example, you can first measure the highlight of the model's background, and then measure the brightness of the model's face. When the difference value (Δ value) in the metering results of these two areas exceeds the exposure tolerance of the film you are using, the model's background will be overexposed, unless your idea is to get a silhouette.
  The Area 2S light meter comes with a metering bypass metering viewfinder, which is not on the same optical path as the metering lens and has a 17 degree field of view angle. Therefore, when shooting at close range (within 20cm) and macro range, the scene you observe in the viewfinder is significantly different from the picture measured by the metering lens. At this point, it is not possible to rely on a metering viewfinder to observe the image. It is necessary to directly align the metering lens of the Area 2S light meter with a specific area for measurement.
  Therefore, when using a certain type of film for photography, it is necessary to know the exposure tolerance of the film, and then through correct metering, it is possible to obtain a perfectly exposed photo, which is very different from taking digital photos.
