If it is versatility that you are after, look no further than the Pentax-FA HD 31mm f1.8. As a noteworthy addition to the HD PENTAX-FA Limited series, this lens stands as a high-performance wide-angle prime, well-suited to a range of everyday shooting applications. Authenticity and intricate detailing come as standard to the PENTAX-FA Limited series, with the 31mm maximising its bright f/1.8 aperture to excel in low-light. Depth of field control assists in isolating your subject, whilst the nine-blade rounded diaphragm grants you a stunning bokeh quality. The PENTAX high-grade HD coating offers a much higher light transmission than conventional lens coatings. This leads to impeccable image rendition and thorough ghosting/flare control for high contrast and accurate, neutral colour balance. The PENTAX SP coating effectively repels dust, stains, and debris from the glass. A 31mm lens with a focus upon aesthetics - both in results and build.

Expanded Pentax-FA HD 31mm f1.8 Limited Lens Key Features:

31mm Magic

This wide-angle 31mm lens is designed for full-frame Pentax K-mount cameras. It can also be used with APS-C models, providing a 46.5mm equivalent focal length. This lens is able to maximise its bright f/1.8 aperture in low-light situations, whilst great control is given over the required depth of field. The nine-blade rounded diaphragm produces a stunning bokeh that adds depth and contrast to your image. This lens, therefore, affords sharp imaging performance with natural perspective and high contrast - ideal for architectural photography. Whilst the large aperture and depth of field control are valuable assets for landscape and street photography.

The Limited Series

Some 25 years ago, PENTAX introduced the ‘Limited Series’ at the time of traditional SLR technology. They got straight to the point, producing three lenses with distinct focal length designations to include; a wide-angle 31mm, a standard 43mm, and a portrait-specific 77m. The common theme became clear; intricately detailed construction for impressive imaging quality. This now forms the foundation of the HD PENTAX-FA Limited series consisting of the 31mm f1.8, 43mm F1.9, and the 77mm F1.8.

Aesthetic Appeal

The Pentax-FA HD 31mm f1.8 Limited Lens is stunning. The design effortless combines the modern with the traditional, with a sleek and portable body, vintage accents, and accessible aperture ring. A fully-integrated lens hood, exclusive aluminium lens cap, and lens bag are also provided.

In regard to the aesthetics of your imagery, the Pentax-FA HD 31mm f1.8 utilises an SP (Super Protect) coating to repel dust, stains, and debris. It also makes the glass easier to wipe-down after a shoot and is highly resistant to abrasions and scratching. The PENTAX high-grade HD coating then offers a much higher light transmission than conventional lens coatings. In terms of imagery, this allows for maximum contrast and sharpness without flare and ghosting. This is even possible when employing a bright back-lit set up in the studio, something conventional lenses would struggle with.

  • 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.

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.
