Keks KM02 Overview

From Manufacturer

The KEKS KM02 OLED Light Meter is an ultracompact, reflective light meter that attaches to your camera's accessory shoe and provides reflective exposure readings. It features a 30° field of view, roughly equivalent to a 50mm lens. It keeps things simple with a straightforward user interface and a simple four-button layout. Useful features include aperture and shutter priority modes, two levels of information display, and even upside-down display for Rollei 35 users. This handy meter is almost tailor-made for vintage film cameras, blending seamlessly with the body and providing an essential tool for accurate exposures.

Highly-Accurate Sensor
The KM02 uses a VEML7700 ambient light, 16-bit, digital resolution sensor. The upgraded software ensures high accuracy, reliability, and combined with a 50mm lens view, a balance between average and selective metering.
3 Aperture, Shutter, and ISO Stops
The KM02's aperture, shutter speed, and ISO stops are all customizable to meet the needs of your different cameras and lenses. With full, half, and third stops, the KM02 is easy to operate and capable of more accurate readings. Settings can be saved for up to 3 cameras/lenses.
Max/Min Aperture & Shutter Speed
The maximum/minimum aperture and shutter speed value can be set according to your individual cameras and lenses. This prevents the meter from displaying unnecessary readings.
Exposure Compensation
The exposure compensation feature allows you to manually adjust the exposure from -3EV to +3EV in 1/3 increments.
Applicable to More Cameras
The KM02 comes with three different sizes of aluminum shoe mounts and has 5 different shoe mount positions. This level of versatility allows you to mount it with a bias to the right or the left. This enables the KM02 to be fitted on any camera with ease.
Two Metering Modes
  • Continuous Metering Mode: Light-meter reading will update constantly with data refresh at every 0.6s
  • Single Metering Mode: Single click the metering button to take a new reading

Keks KM02 Reviews

Meter is good - just don’t expect to adjust the plate

By Martin
Rated 2 out of 5
Date: 2025-08-19

I used this meter with my Hasselblad and enjoyed the experience. It tested similar to my phone and other meters for accuracy. When switching it over to my leica, I wanted to move the mounting plate. Using the provided wrench immediately stripped the screws. I have correctly used allen wrenches for over 20 this was not user error. I contacted Keks, who insisted I try using the ‘correct screwdriver’ and that using the provided one would not work. How dumb of me to ave used the tool that was provided. Their solution, after numerous emails back and forth, was to have me send the entire meter back to Hong Kong and have them replace the entire bottom panel. This seems excessive, and I will be out my meter for a long time. I haven’t tried their screws with different wrenches yet, as mine are all stripped from their tool, so buyer be ware.

awesome
