Product information
Add the Canon L-Series EF 1.4x III Lens Extender to your L-Series lens to increase your focal length without sacrificing image quality.

Specially designed to work with L-Series IS super-telephoto lenses with EOS bodies, the Extender EF 1.4x III increases your focal length by 40%, making it easier to catch far-away action.

Only sacrificing one stop of effective aperture, the Lens Extender is a cheaper and easier way to get more out of your existing lenses without having to expand your lens collection.

An internal microprocessor accurately transfers the data between lens and camera for seamless autofocus and light metering so you don't delay or miss a golden photo opportunity.

Constructed of nine elements in five groups, the Lens Extender is lined with anti-reflection material and coated to reduce flaring for a truer image and clearer results.

Compatible with their range of professional quality L-series lenses, the Canon L-Series EF 1.4x III Lens Extender is a cost effective and efficient way to boost and transforms your existing telephoto and telephoto zoom lenses.

I am not qualified to test this equipment fully but it does not seem to have affected the image quality. Also it does not appear to have reduced the amount of light getting to the camera sensor noticeably.

Delivering your online order

Get this delivered when it suits you

We’ll show you your current delivery options for this item in checkout. Subject to the time you order, and where you want delivery, these options will include:

  • FREE standard delivery in 5-10 working days
  • Next day delivery or any following day between 8am & 5pm (£5.00)
  • Delivery in a timeslot of your choice next day or any following day (£10.00)
Please note: if we’re out of stock of an item but getting more in, we indicate – on listings pages and the product page – how soon we can dispatch for delivery to you. In this case, please go ahead and order, and we’ll contact you later to confirm an exact delivery date.

Important update on our delivery service for small items

Our courier partners (DPD, Royal Mail and On the Dot) have all updated their delivery processes to take extra precautions due to Coronavirus (COVID-19). Please follow the below advice:

1. Customers can use the DPD app to nominate a ‘safe place’ for their delivery to be left if they do not want close contact.

For customers unable to use the DPD app, DPD is still able to offer a contact-free delivery, and will take a picture of the property and capture a proof of delivery name instead of capturing a customer signature.

2. Royal Mail is an unsigned service . Where Royal Mail needs to deliver a parcel, its teams will place the parcel at the customer’s door. Having knocked on the door, the delivery teams will step aside to a safe distance while the item is retrieved. If the delivery cannot take place, Royal Mail will take the parcel to the local depot for collection by the customer.  The parcel will be held for 18 days as per normal process.

3. For On the Dot, where a standard signature delivery is not possible, On the Dot will attempt to leave the parcel in a safe place and inform the customer of where the parcel has been placed.

To see the courier partner for your delivery, please check your dispatch confirmation email (which will also include your tracking reference).
