Flash Duration Measurements
Measuring the flash duration or “burn time” of a flash exposure has always been a critical part of any fast moving subject such as sports, fashion, wildlife, and special effect flash photographs. Unfortunately, flash duration meters have always expensive, complicated and additional piece of gear to carry, until now. The SpeedMaster L-858D’s extremely responsive system offers selectable flash duration measurements from t=0.1 to 0.9. Setting flashes to yield the fastest, or the slowest, is now quick, precise and easy.
Measuring the stroboscopic bursts of HSS flash to determine accurate flash exposure has always been considered impossible with the traditional meters. The L-858D’s highly responsive measuring system, monitoring the level of HSS output, is a game changer for HSS shooters, especially when shooting with multiple HSS flash units.
Optional Radio Transmitter
After years of successful development and market popularity with the PocketWizard radio triggering system, Sekonic now offers optional radio trigging modules for L-858D to control Elinchrom EL-Skyport system and the Phottix Strato/II protocol products. Triggering features range from basic flash triggering to multi-zone and channel triggering, power control, modelling light, camera triggering and much more.
Because every digital camera, lens, and software is unique in its capability to capture and process light, each can produce differences in the tonal range (dynamic range) and exposure of an image. Knowing the limits of your camera’s capabilities enables making better exposures with less post-processing, and ensures you’ll get what you see. Sekonic’s pioneering Data Transfer Software allows quick dynamic range mapping and camera/meter calibration for the most precise control of light. Create and store up to ten camera exposure profiles with Sekonic, X-Rite or Datacolor brand calibration targets.

Fulfil at least one of the following employment criteria:
In regular, permanent employment.
Retired from regular employment - With a minimum age of 50.

The approval of your application depends on your financial circumstances and borrowing history. Warehouse Express Ltd trading as Wex Photo Video act as credit broker and not the lender. Barclays Partner Finance act as the lender.
Can I repay early? If so how?
No repayments are scheduled in the initial six-month deferral period. However, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is fully repaid within the six-month deferral period, then no interest is payable, but a £29.00 early-settlement will be incurred. Such repayments may be made to Barclays Partner Finance by cheque, debit card or standing order. Unfortunately it is not possible to set up a direct debit within the deferral period. Further information on how to make such repayments will be set out in the loan agreement pack provided by Barclays Partner Finance.
What happens if I don't repay within the first six months (deferral period)?
Following the six month deferral period, Barclays Partner Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 19.9% APR on outstanding balances (backdated to the first date of the loan). Late payment penalties and early repayment charges will apply from this point. Barclays Partner Finance will send a reminder letter approximately one month before the six month deferral period is due to elapse. Note: If you chose to spread the cost and pay monthly, interest is charged from the start of the loan, not from the start of the repayment period.
What will I receive from the finance provider (lender)?
Barclays Partner Finance will send a loan agreement pack approximately four weeks after delivery of the goods, confirming that the account has been activated and, from this point, it is possible to make repayments against the loan. You will also receive reminder letters and text at the end of the deferral period to remind you when your first payment is due.
