Sorry, there are no more available.
The Pentax HD DA AF 1.4x AW Rear Converter extends the focal length of the attached Pentax lens by 1.4x, while maintaining autofocus functionality (providing the lens has a maximum aperture of f/4.0 or brighter) and minimum focusing distance. The Rear Converter is made with a weather-resistant, dustproof construction for all-weather shooting and mounts between the camera body and main lens. The converter is compatible with the Pentax K-3, K-50, K-500, K-30, K-5 II, K-5 II s, K-5, K-01, K-7, and K-r.
Key Features: Pentax HD DA AF 1.4x AW Rear Converter
Optical systems optimized for APS-C sensors
Compatible with both in-lens AF(SDM,DC) and in-body AF
Dust & Water proof constitution (AW)
1.4-times focal length extension for telephoto effect
By mounting this rear converter between the camera body and main lens, the user can extend the focal length by 1.4 times.* Measuring only 20 millimeters long, its compact, lightweight design allows the user to more easily reach out to distant subjects. The minimum focusing distance of the main lens is retained despite the extended focal length, providing for the capture of larger, more detailed images of the subject in close-up shooting.
The first PENTAX rear converter to provide AF compatibility
When coupled with an AF lens, the autofocus operation can be performed by the main lens. This rear converter works perfectly with both the camera-driven AF system and the lens-driven AF system (such as the SDM- and DC- series lenses).**
Weather-resistant, dustproof construction for active outdoor shooting
Equipped with 3 airtight seals, this model is the first PENTAX rear converter with a weather-resistant, dustproof construction. By combining it with PENTAX’s weather-resistant, dustproof camera body and lens, the user can assemble a dependable digital imaging system that performs superbly even under harsh outdoor conditions, such as in the rain or in a cloud of dust or sand.
Exceptional optical performance
Thanks to its state-of-the-art optical design, this rear converter assures the exceptional optical performance that optimizes the potential of the main lens. With the application of PENTAX-developed HD coating*** - a high-grade, multi-layer coating designed to minimize reflectance inside the lens while optimizing light transmittance - it lets the user capture crisp, high-contrast images free of flare and ghost images, even under such adverse lighting conditions as backlight.
*When this rear converter is mounted, the lens maximum aperture will be smaller (darker) by 1 step.
**The camera’s firmware must be updated to the latest version before using the autofocus function. Compatible camera bodies are: K-3, K-50, K-500, K-30, K-5 II, K-5 II s, K-5, K-01, K-7, and K-r. Autofocus is possible with a PENTAX lens having maximum aperture of f/4 or brighter.
*** HD stands for High Definition.

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.
