The EF 400mm f/4 DO IS USM is the worlds first super telephoto lens incorporating "Multi-Layer Diffractive Optical (DO) Element", for camera lenses, which corrects chromatic aberrations. By incorporating this optical element in the optical design, the EF 400mm f/4 IS USM is much smaller and lighter than a comparable lens having conventional optical elements. Comes complete with Canon ET-120 lens hood.

The Canon EF 400mm f4 DO IS USM Lens

The key features

  • One DO (Diffractive Optic) lens element
  • One Fluorite lens element
  • L-series construction and optics
  • Fast, quiet autofocus
  • Super Spectra coatings
  • 52mm Rear drop-in filter holder
  • Hard case and lens hood

Diffractive Optics technology
A unique approach to lens design. The EF 400mm f/4 DO IS USM incorporates a multi-layer Diffractive Optical (DO) element, meaning it is smaller and lighter than lenses of conventional equivalent design. The DO element – developed by Canon – is a milestone in optical design, combining the properties of fluorite and aspherical elements in one.

L-series quality
The L-series is Canon's flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are resistant to dust and moisture.

Image stabilization
The EF 400mm f/4 DO IS USM features Image Stabilisation technology that permits the use of shutter speeds two stops lower than normal without blur from camera shake.

Ultrasonic focusing
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.

Super Spectra coating
Super Spectra coatings ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera's sensor.

The lens comes supplied with a lens hood and a hard case.

Are you eligible for finance?

Applicants must be:

  • Aged 18 years or older from the application date
  • In permanent UK residence for a minimum of three years
  • Fulfil at least one of the following employment criteria:
    • In regular, permanent employment.
    • Retired from regular employment - With a minimum age of 50.
    • Not working through disability.
    • Self-employed.

Note: All applicants will be subject to a credit reference check by the lender.

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.
