Since its introduction, Sekonic's L-358 Flash Master has become the best-selling digital flash meter in its class. Weather-sealed against the nastiest of working conditions, the L-358 delivers dead-nuts accurate flash and ambient light reading in both incident and reflected modes.For mixed lighting scenarios, the L-358 displays the combined exposure values of both flash and ambient light sources, including the percentage of flash in total exposure in 10-percent increments. Dual ISO buttons allow for quick exposure factoring when working with two differing film speeds, film and Polaroids, or other situations where comparison readings are desired.
From the Manufacturer
L-358 FlashMaster
The Sekonic L-358 displays an f-stop range of f/1.0 to f/90.9, and a shutter speed range of 30-minutes to 1/8000th-of-a-second (1/1000th in Flash mode), both of which can be displayed in full-, half-, and third-stop intervals to mirror your camera's exposure display. When set to "full," the exposure is displayed in tenth-of-a-stop increments with repeat accuracy of +/- 0.1 EV.
For motion picture applications, the L-358 calculates cine readings from 2 to 360 frames-per-second. As with all Sekonic meters, the Sekonic L-358 Flash Master includes a 3-year warranty and the best customer support you're ever likely to find.The simple solution to creative light control with optional wireless triggering
Directional light is powerful. It guides the viewer, creates mood, and adds dimension, depth, and texture. If you want to create a signature style that elevates your photography to the next level, the mastery of off-camera lighting should be your next goal.Subjects – clients – are not impressed with a shoot, view, and adjust photo style. Lighting ratios, ambient balance, and final exposure must be set confidently. Knowledge and use of the tools of photography assure that the outcome is the intended one. And for images like this one, the Sekonic L-358is the professional photographer’s meter of choice.
Incident Light Metering
Unlike in-camera metering, handheld, incident light meters don’t require multi-patterned readings, complex exposure control systems, or +/- exposure correction when they fail. They are, in fact, the simplest and most direct way to determine exposure. And because incident meters measure the light that falls on your subject, they provide camera settings that render the image exactly the way it appears. Blacks are black. Grays are gray. Whites are white.Retracting the Sekonic L-358’s Lumisphere enables you to quickly judge the brightness of multiple light sources for fast, accurate adjustment of lighting ratios.
Ambient Light Metering
Take shutter-priority or aperture-priority readings from 30 minutes up to1/8000 second and f/1 to f/90.9 with ¹/10-stop accuracy. The L-358 displays exposure both digitally and on an analog scale for easy readout. Custom functions enable adjusting the shutter speed and aperture readout for full-, half-, and third-stop increments to mirror the setting of your camera. You can change exposure settings after reading and the meter will automatically compensate to maintain the proper exposure. And the extended sensitivity range, EV -2 to 22.9 for ISO 100, allows taking exposure measurements in virtually any kind of light.Flash Light Metering
Shutter-priority readings of flash light can be made with a synch cord or cordlessly at shutter speeds from 30 minutes to 1/1000 second.The L-358 automatically resets after each reading in cordless mode to enable fast adjustment of flash brightness. The multi-flash function enables accumulating an unlimited amount of flash pops for times when a single flash pop cannot achieve the proper exposure or the amount of depth of field needed for the subject.Optional Radio Flash Triggering
Simply plug the optional Sekonic RT-32 Transmitter Module into the battery compartment and wirelessly trigger flash units up to 100 feet away. The transmitter offers 32 digital coded channels and Quad-Triggering Zones and is compatible with PocketWizard® radio triggering systems, as well as the PocketWizard Wireless Freedom partners.
Analyzing Function
The L-358 is especially useful for on-location shooting to lighten shadows or reduce background detail. That’s because it measures ambient and flash simultaneously and automatically indicates the percentage of flash in the total exposure. You can easily adjust the ambient flash mix by turning the Jog Wheel. The digital display indicates the camera settings and an analog display shows the relationship between ambient and flash and the total exposure.
Sekonic L-358 Functions
All controls are at your finger tips. Familiar Jog Wheel operation and large LCD readout make settings fast and easy.Contrast Function
Setting up lighting ratios or checking the evenness of a background or scene is push-button simple. Take a reading of the key or reference light and press the AVE/?EV button to create a standard. Then press the measuring button to display the brightness difference between the standard and new reading.

This is an excellent flash and exposure meter suitable for checking your modern digital camera or for measuring exposure if you still use an older camera without a meter or if the metering system is no longer performing properly and cannot be repaired. It is simple to use and much more accurate than is necessary, it measures to 1/10th of a stop which is unnecessary for film or digital photography.The purchase ran smoothly and went according to Amazons usual high standard.

This is my first light meter, so take this with a grain of salt, but so far it has been excellent. It does everything I need (especially flash metering) and even some things that I don't need.I spent quite a while looking at meters in the $100-$300 range that at least did flash metering, and I came to the conclusion that it makes much more sense to buy this all-in-one meter with extra features for $300 than buy a flash-only meter for less and then have to buy an incident light meter later especially when both together for a total cost of $300 or less would probably do less than this one meter does for the same cost. This was the best value in light meters that I could find, and I looked at quite a few. It seems that all of the research paid off and I made a good decision.My only wishes are that: 1) I wish I could set the shutter speed and aperture and have it tell me what ISO sensitivity is needed for the given lighting conditions; 2) it "only" goes up to f/90. Issue #1 is easy to work around (just hold down an iso button and turn it up from 100 until the aperture and shutter speed you need are displayed). Issue #2 really only matters because I have a f/177 pinhole camera "lens" that the meter is very useful for calculating the exposure time for... I just have to multiply whatever exposure time it gives me for f/90 by 4 (which would technically be the time for f/180 but that's close enough given my unwillingness to do the math to adjust it for exactly f/177).Given that there's an easy workaround for both, and the latter only comes in to play rarely, neither of these are a big deal. After all, the designers can't possibly imagine every possible thing that someone might want, and the meter already has a bunch of other features (like memory, averaging, EV delta v, multi-flash metering, etc.) that have either already come in handy for me or probably will rather soon.I also wish it used standard AA batteries (since I have a bunch of rechargables) but I don't consider the lack of commonly available battery support to be that big of a deal.If you need a light meter that does ambient/incident light, reflected light, and flash (with or without synchronization) then this has to be one of the best, if not the best, that you can get for the price.

Le Sekonic L-358 est un flashmètre professionnel. L'usage des fonctions de base de mesure de lumière réfléchie (lumière ambiante flash) est très simple, même le paramétrage des micro-interrupteurs pour configurer le boîtier est clairement expliqué dans le manuel. En outre, l'ensemble du boîtier est résistant aux projections d'eau (joints toriques aux endroits critiques. Dès que la luminosité ambiante baisse, le rétro-éclairage de l'écran s'allume automatiquement. Mais ce flashmètre dispose également de fonctions avancées comme l'affichage du ratio flash / lumière ambiante (qui permet de connaître le niveau de fill-in introduit par le flash), la mesure de variation d'exposition (combien le diffuseur "prend"-il de lumière sur un modeleur). La sphère intégatrice rétractable (la boule blanche) est de plus très pratique pour régler un éclairage multi-flash en studio. En outre, il est possible d'installer un transmetteur pocket-wizard pour les photographes déjà équipés de ce type de déclencheur radio.Pour la différence de prix avec le L-308s (certes plus petit, mais je ne trouve pas le L-358 si gros), les avantages offerts me semblent intéressants. seul bémol, la pile CR123A (fournie) coute plsu cher à remplacer qu'une pile AA standard, mais c'est le genre de pile (lithium) qu'on doit remplacer tous les 2 ans (cela dépend évidemment de l'usage que l'on fait du flash-mètre !)

Insgesamt ist der Belichtungsmesser gelungen - die Messergebnisse stimmen und im Studio will ich nichtmehr ohne sein. Fast alle Bedienelemente lassen sich im "Einhandbetrieb" problemlos erreichen.Das fature, bei einer Blitzmessung den Anteil des Blitzlichts an der Belichtung in Prozent angegeben zu bekummen war für mich kaufentscheident. Weiterhin finde ich die Möglichkeit zwischen 2 ISO-Einstellungen per Tastendruck wechsen zu können - ohne jedesmal alles am Gerät zu verstellen - ganz praktisch.just for Info:der ISO-Bereich geht von 3 bis 8.000die einstellbare Blende geht von 1.0 bis 90was mich stört ist folgendes:der Aufdruck erfolgte meine Ansicht nach mit der falschen Farbe - jenachdem, wie das Licht auf das Gerät fällt (z.B. wenn man das Licht im Rücken hat), kann man die Beschriftung nicht lesen (das Plastik reflektiert einfach zu stark). Da ich nicht ständig mit dem Gerät arbeite, bin ich dann doch auf die Beschriftung angewiesen (klingt albern aber: könnten Sie einen Brief tippen, wenn keine Buchstaben auf den Tasten der Tastaur sind?).Weiterhin ist mir aufgefallen, dass manchmal die Hintergrundbeleuchtung nicht automatisch funktioniert - eine Taste zum einschalten wäre da schön.Zur vorherigen Rezension: mittlerweile ist im Handbuch auch ein deutschsprachiger Textteil enthalten - Der Quick Guide ist weiterhin nur in englischer Sprache:Fazit: nicht das billigste Geraät aber mit einem dem Preis angemessenen Funktionsumfang. Leider leistet sich der Herstelle kleine Schwächen am Gehäuse

This is just a well made meter and very easy to use. I read the instructions once long ago and no issue after that. It is fairly intuitive. Most of my flash use is strobist off camera multi-flash using Nikon CLS to control exposure and portable modifiers. I carry the meter when I need to switch to manual control. I like that I can remember how to use this meter regardless of how long it has been since I last needed it. This meter shines for use with studio strobes. During the few occasions I shoot sharing strobes, I have noted my and other shooters' Sekonic meters have always been consistent. I have added the optional radio module. It is convenient to be able to test flash for meter readings without having to use the camera or the radio trigger on the camera. On the downside this meter uses the more costly CR123 battery ($5+) which is not available at your local grocery store. This is mitigated in that battery life is very good. The meter also works well with CR123 3 Volt (NOT 3.6 Volt!) rechargeables. I have not attempted to use the 3.6 Volt rechargeable batteries and would caution anyone thinking of doing so to verify with Sekonic the overvoltage will not be detrimental.Update: Since writing this review I have moved on to a Sekonic L-478DR meter in order to have the remote control capability of Pocketwizard Flex units. However I still retain the L-358 as a spare/backup/loaner. I still recommend it as a Pro level meter at an entry level price, especially with used units at lower prices being available.

I read a light meter review recently where the reviewer said; "even if you don't think you need a light meter, you do." This is good advice.Three huge advantages come to mind after using this meter once.First, it is a tremendous time saver during the shoot and afterwards in post processing, take a light reading, set your camera to what the meter reads and shoot.Second, repeatability - even if you are shooting low/high key or going for artistic effects; you can reproduce lighting ratios/scenarios you like easily in the future. When you don't have a light meter you can spend countless hours tweaking the power settings on your strobes or multiple shoe mount flash units to get a few shots right.......and when you're done and have packed it all up......the next day, week, month....you have no way to get back to those settings again.Third, better pictures.Having an LCD/preview and histograms are useful but DSLRs, even the most advanced cameras in the world, can not do what a light meter can. In camera metering has no way of measuring or calculating the light output from studio strobes. TTL, iTTL & all these intelligent flash systems (for shoe mount flash units) still have a place when you are shooting events and there is no time to take light readings. But after using this light meter I can honestly say that if there is time and the shots are important I will never rely on iTTL systems ever again. iTTL flash results are all over the place, when you meter the light and shoot in manual the results will be 100% predictable 100% of the time. My speedlights are going to live in manual mode when there is time to use a light meter from now on.I doubt you can beat the Sekonic L-358 at this price point. I've only had this meter a few hours but like so many others have said, I wish I had purchased this a long time ago. This is a 5 star product, it works great and is reasonably priced.
