L-858D-U
With it’s 2.7” color touch screen and truly innovative and sophisticated features, the Sekonic Speedmaster L-858D-U leads the way to the next generation of light measurement control as the world’s first multi-function light meter for photographers and filmmakers. Leveraging over 60 years of experience in the image-making world with cutting-edge technology, the Sekonic Speedmaster L-858D-U has undergone a significant design change and boasts a comprehensive feature set sure to meet and exceed the demands of today’s photographers and filmmakers.

The first meter of its kind capable of measuring flash duration, while also being able to achieve an accurate ambient exposure reading in dimly lit scenes as low as 0.1 lx, the Sekonic L-858D-U provides image-makers of all levels with the critical exposure data they need to create stunning and beautiful imagery.

The first to provide wireless compatibility with Godox products (Replacable with broncolor, Elinchrom, Phottix and PocketWizard transmitter sold as separately), the Sekonic Speedmaster L-858D-U also provides ultimate control to photographers seeking a faster and more streamlined workflow. Limitless creative possibilities are within reach through the meter’s ability to measure High Speed Sync (HSS) and calculate proper ambient-flash exposure for precision flash exposure control.

With an increased light-sensitivity and extended ISO and Shutter Speed Ranges, the Sekonic Speedmaster L-858D-U enables all image-makers to obtain measurements in extremely low light and turn those readings into creative decisions. Finally, matching the high-ISO capabilities of today’s cameras, by accurately metering in low-light, is finally possible.

CA Proposition 65

Attention to all California residents, Proposition 65 or officially known as, the Safe Drinking Water and Toxic Enforcement Act of 1986, is a law that requires warnings be provided to California consumers when they might be exposed to chemicals identified by California as causing cancer or reproductive toxicity. The warnings are intended to help California consumers make informed decisions about their exposures to these chemicals from the products they use. The California Office of Environmental Health Hazard Assessment (OEHHA) administers the Proposition 65 program and publishes the listed chemicals, which includes more than 850 chemicals. August 2016, OEHHA adopted new regulations, to go into effect on August 30, 2018, which changes the information that is required in or on Proposition 65 warnings.

We want you to know and be aware of our product safety and Midwest Photo is taking all of the necessary steps to comply with the applicable safety and health requirements made by this Proposition 65.

WARNING: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

This disclaimer can be found on the product pages on our website under the Additional Information tab which appears below the product description. It is listed on all product pages to ensure that our customer is aware of the warnings put out by our suppliers so you can know the precautions before purchasing.
