Product Review: Sekonic L-308X-U Flashmate Light Meter (401-305)

Are you tired of guessing the right exposure for your photos and videos? Do you want to take complete control of the light in your shoots? If yes, then the Sekonic L-308X-U Flashmate Light Meter is the perfect tool for you. Based on our research and user feedback, we believe it is an excellent solution for both amateur and professional photographers and videographers.

Accuracy down to a tenth-of-a-stop

One of the most remarkable features of this light meter is its ability to provide accurate exposure readings down to a tenth-of-a-stop for both ambient and electronic flash light. This means you can achieve your desired exposure more precisely, resulting in better image and video quality.

Flexible ambient and flash range

With an ambient EV range of 0 to 19.9 at ISO 100 and a flash f/stops range from f/1.0 to f/90.9, the Sekonic L-308X-U Flashmate Light Meter provides a wide range of options to capture the right exposure for different shooting situations. It also has a shutter-speed span of 60-seconds to 1/8000th-of-a-second for ambient light, and 1 sec to 1/500th for flash, which gives you more control over your image and video creation.

Three modes to suit your needs

The Sekonic L-308X-U Flashmate Light Meter offers three different modes to suit your shooting needs. First, the Photo Mode is perfect for still photographers who want to achieve a complete range of ambient and flash functions. You can display shutter or aperture priority mode, including cord and cordless flash measurement.

Second, the HD Cine Mode caters to DSLR and mirrorless videographers who need to take exposure readings and control light using shutter speeds and frame rates. This allows you to adjust and control the light on your subject, resulting in a high-quality video.

Lastly, the Cine Mode is designed for use with cinema-grade cameras. It allows you to select from the most useful frame rates and shutter angles for exposure control with one-tenth stop accuracy. Therefore, if you are a professional videographer, you will benefit from this mode.

User-friendly interface

The Sekonic L-308X-U Flashmate Light Meter has a user-friendly interface that is easy to understand and operate. It has a large and clear LCD that displays all the necessary information, including ISO, shutter speed, aperture, and flash power. You can also customize the screen with your preferred settings.

Compact and lightweight design

The Sekonic L-308X-U Flashmate Light Meter is compact and lightweight, making it easy to carry around. You can easily fit it inside your bag or pocket, and the included strap adds an extra layer of security to protect it from accidental drops.
