Paul C. Buff AlienBee Einstein 640Ws Studio Flash


Jeg vælger at sælge disse fantastiske lamper af den simple grund at jeg ikke får dem brugt. Kort sagt så finder du ikke lignende lamper på markedet til denne pris. Prøv at google navnet og læs hvad fotograferne skriver om dem. De er meget populære og ganske eftertragtet. Paul C. Buff har deres egen europæiske distribution af disse, og det er osse igennem dem at jeg har købt alt mig Paul C. Buff(PCB) grej. Jeg er sikker på du vil finde mine priser ganske rimelige i forhold til ny-prisen og fragten oveni.

Jeg har stort set ikke brugt disse lamper. De har stået på mit kontor og ventet på at blive brugt. Men det er desværre aldrig sket. Jeg har ufattelig meget grej til dem i form af softboxe, grids, osv. osv. osv.. Tjek evt. resten af mit site ud.

Én ting jeg vil understrege er at, hvis du vil købe en “Einstein”, så kan jeg kun kraftigt anbefale også at købe et af de PCB Vagabond Batterier jeg har til salg. Dem synes jeg osse du skal google. Så er jeg sikker på du er overbevist. Batteriet vejer intet og kan skyde hundredevis af skud med en Einstein på fuld styrke.

Jeg kunne blive ved med at skrive om disse lamper i en evighed. IStedet sætter jeg nogle billeder ind. Nogle taget fra PCB website, og andre taget af mig på mit lille kontor. Under billederne er der en hulens masse copy/paste tekst fra PCB’s website.

Ny prisen for en Einstein er pt. Kr. 5.240,-. Dertil skal du tilføje Dansk moms osv., som omregnet er ca. Kr. 1.000,-.

Min pris per Einstein er Kr. 4.000,-.

Jeg har 2 stk. til salg.

We are pleased to present the most advanced integrated studio flash system ever conceived – Einstein™.

Einstein™ is a powerful, all-digital, self-contained flash unit using multiple IGBT devices to allow a 9 f-stop power variability range from full (640 Ws) to 1/256 power (2.5 Ws), adjustable in precise 1/10 f-stops with voltage regulation consistency over the entire operating range.

Einstein™ offers global plug-and-play with automatic power switching that allows the unit to operate on power lines from 95VAC to 265VAC, 50 or 60Hz, automatically sensing the voltage / frequency and adjusting accordingly with no user attention required. The unit can tolerate power line voltages as low as 35VAC from the Vagabond™ II portable power system or from other similar pure sine inverters without crashing, whereas many competitive digital flash units crash if the input voltage falls below about 80 to 90VAC. No user intervention or lamp changing is required to operate at different AC line voltages.

Einstein™ recycles to full power (at 120VAC or at 240VAC, 50Hz) in just 1.7 seconds, with the recycle time proportionally decreasing as the power setting is reduced. When recycle is complete, the READY state can be indicated both audibly and visually, selectable from the rear panel. An advantage of the IGBT flash control is that, at reduced power settings, the flash capacitors are not completely drained when the unit is fired making it possible to perform a rapid sequence of shots as the unit can be fired before the READY state is reached. Depending on the power setting and number of frames per second being shot, this can produce successive reductions of exposure value and color temperature in a rapid series of shots at relatively high power. In typical fast action sports shooting, setting the power to around 1/10 power (64 Ws) will allow frame rates or bursts on the order of five to ten frames per second with excellent frame to frame consistency and extremely sharp action freezing.

Two distinct operation modes are available from the rear panel: the Constant Color mode and the Action mode. In Constant Color mode, the emitted color temperature is held constant at 5600ºK (+/- 50ºK at any power setting or input voltage). The flash duration ranges from 1/540 second (t.1) at full power to 1/1700 second (t.1) at half power to 1/9,000 second (t.1) at the lowest power setting. In Action mode, the flash duration is minimized for maximum action stopping capability where absolute color consistency is secondary to motion freezing. At half power in Action mode, the flash duration is approximately 1/2000 second (t.1) and the color temperature is approximately 5750º K. In this mode, the color temperature rises as power is reduced.

Einstein™ includes a flash sensitive built-in slave tripper for wireless firing and arrives with a standard 1/8″ to PC sync cord for direct camera connection. The unit may also be fired from the optional CyberSync™ CSXCV Transceiver / Cyber Commander™ or third party radio triggers. See the Compatibility tab for more info.

Adjustments are made with the function and adjust buttons on the back control panel, with all parameters displayed on the back-lit, high resolution color LCD screen (320 x 240 pixels, 2.4″). At all times, the screen indicates the output level of the flash (the f-stop, wattseconds, and EU number), the color temperature, the t.1 flash duration, the output level of the modeling lamp (the f-stop and watts), the modeling lamp setting (on, off, track or independently adjustable), the recycle READY status and setting, the slave eye status, the action or color mode selection, and the CyberSync™ channel and frequency selection.

Einstein™ additionally features an “Easy Set” button used for instant setup to the most commonly used function parameters. When pushed, Einstein™ is ready to use in plug-and-play fashion for most users, with both visible and audible READY indicators, the slave sensor on, Constant Color mode selected and CyberSync™ channel/frequency both set to ‘1’. After pushing the “Easy Set” button, the user can then use the function button to change any of the settings mentioned.

Each unit arrives with a UV-coated, single-ring flashtube and a standard 250 Watt (120V) bayonet-style quartz modeling lamp that is precisely voltage-controlled to maintain consistent luminosity and to track flash power within +/- 1/10 f-stop at any AC input voltage and any power setting within its specification. The design of the modeling lamp regulator is proprietary to Paul C. Buff™ and yields dramatically less interference transmitted back to the power line in comparison to the unregulated and inaccurate household-style “phase control” dimmers used in most flash units. A frosted pyrex dome protects the lamp and tube from damage and serves to reduce UV emission from the flashtube. It equalizes the effective size and shape of the modeling lamp and flashtube as the modeling lamp filament is in exactly the same focal point as the UV-coated flashtube, resulting in an extremely close relationship between the flash and modeling light. The dome lowers the color temperature by approx. 300K. An optional UV-coated dome (sold separately) further lowers the color temperature by approximately 600K.

A high velocity fan and improved airflow coupled with multiple internal heat sensors and circuit fault detection assure reliable performance under the most demanding commercial shooting.

Einstein™ also includes a Micro SD card slot for a standard 2GB card (not supplied), used to upgrade the firmware via download or email should features be added in the future.

Light Stands: The Einstein™ flash unit must be securely mounted to a light stand for use. The stand mount on the unit is compatible with most standard light stands having top couplers up to 5/8-inch and may be used on our Paul C. Buff™ LS1100, LS3050, LS3900 and TS13AC light stands as well as our MBA Baby Boomer™.

Portable Power: For portable, battery power we recommend the use of our Vagabond Mini™ Portable Power System.

Remote Controls: Einstein™ includes a slot for the CyberSync™ CSXCV Transceiver for use with the Cyber Commander™ to provide complete wireless firing and parameter adjustment. With this setup, the Cyber Commander™ can be used to remotely power on an Einstein™ unit that is plugged into a power source. The unit may be used with all CyberSync™ transmitters and receivers. Einstein™ may not be used with the LG4X wired remote control or older Paul C. Buff™ remotes incorporating the telephone cord connection. The unit is compatible with most other third party triggering receivers (such as the PocketWizard®). A 1/8-inch to 1/8-inch non-attenuated mini male mono cord such as our CSSC is required to connect the receiver to the Einstein™.

The Einstein™ is additionally compatible with the PocketWizard® PowerMC2 for use with the PocketWizard® system.

PLM™ and Umbrellas: The Einstein™ unit has an umbrella shaft that runs along the top length of the unit housing, fitting standard umbrella poles up to 23/64” (approx. 9mm) in diameter. It may be used with the PLM™ system (both the current model and previous models) as well as retired Paul C. Buff™ umbrellas. The PLM™ system’s the on-axis speedring mount may be used as well.

Softboxes: The faceplate on each Einstein™ unit has four holding fingers that expand and contract to hold speedrings for softbox and octabox attachment. The unit may be used with any of our foldable softboxes, octaboxes or stripbox as well as retired models of Paul C. Buff™ softboxes and octaboxes. When using softboxes by other manufacturers, you will need to get a Paul C. Buff™ compatible speedring.

Reflectors: The four holding fingers on the faceplate also expand and contract to hold various reflectors. While the Einstein™ does not arrive with a particular reflector, for general use we recommend the 8.5HOR 8.5-inch high-output silver reflector. The unit is additionally compatible with our 7AB/R 7-inch silver field reflector, the 11LTR 11-inch long-throw reflector, the 22HOBD and 22HOBD-W beauty dishes, the 22RLR Retro Laser™, the UBR background reflector, and the 7UR reflector. The UMF LiteMod™ Unit Mainframe (and its associated accessories) may also be used.
