Canon Extender RF 1.4x Teleconverter for Extended Reach, Fast AF & High Image Quality
The perfect shot is often just out of reach. The Canon Extender RF 1.4x is built to bring distant subjects dramatically closer while preserving the outstanding image quality, autofocus performance, and reliability that professional and enthusiast photographers expect from Canon's RF system. Designed exclusively for compatible Canon RF telephoto and super telephoto lenses, this premium 1.4x teleconverter extends your lens' focal length by 40%, allowing you to capture wildlife, birds, aircraft, outdoor sports, motorsports, and distant landscapes with greater detail without investing in an entirely new super-telephoto lens. Whether you're photographing elusive birds deep in the forest, athletes across the field, or aircraft high overhead, the Canon Extender RF 1.4x delivers the extra reach you need while maintaining seamless communication between your EOS R camera and compatible RF lens. Its advanced optical construction features 7 precision-engineered elements arranged in 4 groups, including high-refractive and low-dispersion glass elements that help suppress chromatic aberration, reduce ghosting and flare, maintain excellent contrast, and preserve impressive sharpness from the center of the frame to the edges. Unlike digital cropping that sacrifices image resolution, this RF extender enables photographers to maximize the native resolution of their camera sensor while effectively transforming focal lengths—for example, turning a 400mm lens into a powerful 560mm, a 600mm into an impressive 840mm, or an 800mm into a remarkable 1120mm telephoto solution. Designed specifically around Canon's RF optical system, the Canon Extender RF 1.4x provides exceptional optical performance with minimal compromise, making it an indispensable accessory for photographers who frequently need more reach without carrying additional heavy lenses.
Built for demanding field use, the Canon Extender RF 1.4x combines premium engineering with rugged durability to withstand challenging outdoor environments. Its professional-grade dust- and moisture-resistant construction helps protect internal components against harsh weather, while the signature white heat-shield coating minimizes heat absorption during prolonged shooting under direct sunlight. Compact and lightweight at approximately 225 grams, with dimensions of just 71.2 mm in diameter and 20.3 mm in length, this extender easily fits into a camera bag and adds minimal weight to your photography kit, making it ideal for travel, wildlife expeditions, and extended shooting sessions. Full electronic communication between the camera, lens, and extender is maintained at all times, ensuring accurate autofocus operation, aperture control, lens metadata transmission, EXIF recording, and compatibility with Image Stabilization systems on supported RF lenses. Photographers continue to benefit from Canon's advanced autofocus technologies, including subject detection, animal eye detection, continuous autofocus, and Servo AF when paired with compatible EOS R cameras and lenses. The optical design has been carefully optimized to minimize field curvature while preserving excellent image quality, allowing photographers to confidently shoot high-resolution stills and professional-quality video without sacrificing performance. Official compatibility includes a growing range of Canon RF lenses such as the RF100-400mm F5.6-8 IS USM, RF100-300mm F2.8L IS USM, RF100-500mm F4.5-7.1L IS USM (with zoom operation from approximately 300–500mm), RF200-800mm F6.3-9 IS USM, RF400mm F2.8L IS USM, RF600mm F4L IS USM, RF600mm F11 IS STM, RF800mm F5.6L IS USM, RF800mm F11 IS STM, RF1200mm F8L IS USM, and the RF70-200mm F2.8L IS USM Z, making it a versatile upgrade for photographers already invested in Canon's RF ecosystem.
Whether you're a professional wildlife photographer pursuing elusive animals, a bird photographer looking for tighter compositions without disturbing your subject, a sports photographer covering fast-paced action from the sidelines, or a passionate enthusiast wanting to maximize the capabilities of your RF telephoto lens, the Canon Extender RF 1.4x delivers outstanding value by extending your lens' capabilities while preserving the premium optical performance Canon is known for. Every aspect of its design—from the advanced optical formula and durable weather-resistant construction to seamless autofocus communication and compact portability—has been engineered to help photographers capture sharper, closer, and more detailed images with confidence.

It is so nice to see a small family owned shop instead of these big box stores. I generally felt cared about when getting my blackmagic cinema camera. Love the quality of the images and how easy it is to use.

This small business has the best customer service HANDS DOWN!!
Lucas worked with me diligently to help me find a camera that would fit my needs and that would arrive in time for my trip. I take photos, but wanted a smaller, more compact camera to take with me when traveling. He even reached out to other camera experts to make sure he was giving me the best advice for the equipment that would accommodate my needs!
Lucas was patient with me and was in constant contact with the camera supplier to keep me updated on the status of my order and when the items would be ready for shipment. Once my order arrived to the store, it was in my hands in less than 2 days. I would give 10 stars to this business if I could!!
SHOP SMALL! :)
AMAZING SERVICE!
In short: I was able to receive the black colorway below retail and free next day shipping with the promos that they offered for being a new camera web-shop based from AZ.
Long story: Lucas who is prolly the only rep for the company cuz they're so small is the best dude ever. Since i ordered he responded on emails and updates quicker than some of my friends texting me back about where am at on the list as people just kept cancelling their order. I went from 9th place in line to 4th place in line for the silver. And he hit me up saying that they were still waiting on Fuji to send shipping updates and that no company knows what they get on their weekly fuji shipments other than from a 24 hour window of receiving shipping details.
He then noted that there were two black X100Vs available that were reserved to customers who ordered but have not confirmed. I said if they dont confirm please let me know and ill take that instead of the silver. The next day he hits me saying the customer said to cancel and he sent me an invoice. I ordered accessories for the camera on amazon right after and my package for the camera came before my amazon package. Lucas was super nice and transparent about everything. Dope experience from NUZIRA.
Lucas was so incredibly helpful!!! I’ve genuinely never had better customer service. They offered to stay late so I could get my order and were so patient with all my questions. I would give them 10 stars if I could.

NUZIRA MADE MY MONTH!
I was a little concerned when I first came across this small business but I am so so thankful I di! They have the NICESt staff and customer service. I have been on the waitlist for this camera for a few months now so when Lucas called saying they had it back in stock I was so freaking excited! Made my whole month. This camera absolutely lives up to the hype. I love how lightweight it is. I can pop it into any bag and head out the door. the images are crisp, high quality, and stunning. I use film sim and not film sim. The film simulations are nearly identical to real film. I have another fuji camera that does film sim but it can't even be compared to this one. I love my Fujifilm X100v so much! Amazing camera! Thanks you Nuzira!
