Sekonic L-758DR-U Overview

Precise, programmable, and easy-to-use, the Sekonic L-758DR-U DigitalMaster Light Meter, available here with PocketWizard radio triggering support, will provide users with the best way to measure their lighting for the utmost in control either in the studio or on location. The L-758DR-U is exceptionally versatile as it performs either incident or spot metering of ambient and flash lighting. Incident metering is possible with a lumisphere on a rotating head. The lumisphere is also retractable for accurate contrast readings. Alongside the more standard sphere is a 1° spot meter with a viewfinder equipped with a full display. Additionally, the L-758DR-U has a wide measuring range of -2 to 22.9 EV at ISO 100, as well as a flash range of f/0.5 to f/161.2.

A huge advantage of the L-758DR-U is the ability to be programmed with optional exposure profiles in order to match the dynamic range of your specific camera. Also, up to nine readings can be memorized and displayed on the screen, and once programmed the meter will show the latitude of your camera as you make measurements. A Contrast Function can further help by allowing direct comparison between a standard mid tone and other measurements. Another feature is the ability to measure both ambient and flash in the scene, with a percentage of how much flash is used. This allows you to see the relationship between the two in order to balance the exposure as needed. Finally, this model is designed for demanding professionals, featuring a large backlit LCD and an all-weather construction.

Built-in PocketWizard radio flash triggering can set off units up to 100' away for simplified measuring. The transmitter also offers 32 digitally coded channels and Quad-Triggering Zones and is compatible with standard PocketWizard systems

question

Is calibrating the meter necessary in order for it to work properly? I'm not sure I want to spend $132 plus time to calibrate when it should work right out of the box.
Asked by: Vladimir
If it was purchased through an authorized dealer in the US any warranty work will be done at no charge. If you press the two ISO buttons at the same time and turn the wheel you can calibrate the meter yourself, to match your camera. This is what should be done. All cameras vary.

question

Can this meter use rechargeable CR123A batteries, such as Tenergy RCR123A? These batteries have a higher initial voltage than the standard non-rechargeables.

question

Is it different between L-758DR and L-758DR-U? Can it compatible with Sekonic Exposure Profile Target II and ColorChecker Passport Photo?
Asked by: OR PIYAPONG P.
The design, construction and functionality of L-758DR-U is identical to L-758DR down to every square millimeter of the device. A while back Sekonic was experiencing trouble with illegal copies of some of its meters, the L-758DR being one of them. So they renamed the meter L-758DR-U and setup some sort of verification process so that now the L-758DR-U is the genuine article but L-758DR is not. I asked this same question directly to Sekonic and that was the answer they gave me. So as a result, if you buy a L-758DR you are not guaranteed it is genuine and not an illegal copy. But with L-758DR-U you are guaranteed it is genuine. If you bought an L-758DR before the illegal copies started taking off or if you bought an L-758DR and are confident it is genuine then it will function exactly the same as the L-758DR-U will. I have no experience with Exposure Profile Target II or the ColorChecker Passport Photo, but if they are compatible with the L-758DR then they are compatible with the L-758DR-U.

Asked by: SANJAY J.
The 758DR is a very good example of the new Sekonic world-market branding. In the USA, the packaging is new and product designations end in U . The 758DR has an incorporated radio antenna and transmitter module for PocketWizard USA triggering standards. It is designed to work with the PocketWizard radios system in the USA. It is possible to purchase the 758DR that is made for markets other than the USA and has a different antenna which works with PW in a different frequency (433Mhz). You pay for this feature when you buy the meter and if not a USA market model, it will never be able to work with the USA PocketWizard system. A meter made for a different market also does not carry a USA warranty. Any warranty service would have to be performed by the country the meter was originally intended to be sold in. The USA warranty is 3-years, the longest available in any Sekonic sales area. That said, B&H always sells the USA specified product and never imports products outside of normal USA channels. You can expect to get the very best product and service from a product purchased at B&H.
