I acknowledge that I have read and understood the Terms & Conditions

Please accept the Terms & Conditions for Auto Replenishment Service before adding the item to cart.

Terms
The following are the terms and conditions ("Terms") for the Canon Canada Inc. Auto Replenishment System (the "Service"). These Terms are between you and Canon Canada Inc. ("Canon Canada", "we" or "us") and govern your and our respective rights and obligations relating to the Service. Your use of the Service is also governed by the shop.canon.ca Terms of Use and our Privacy Statement, each of which (as changed over time) are incorporated into these Terms, and all of which govern our respective rights and obligations concerning the Service. By placing an order through, or otherwise using, the Service, you accept, and agree to be bound by, these terms, conditions, limitations and requirements. Please read these Terms carefully.

Service
We reserve the right to change the Service benefits, including discount amounts and eligibility used to determine discount amounts, at any time in our sole discretion. All such changes will apply to future orders.

When you are enrolled, the Service will automatically create a new order for Eligible Products according to the shipment schedule applicable to the frequency of the Service you have selected, until you cancel.

We may, in our sole discretion, terminate your enrollment at any time without notice. If we do so, you will only be charged for orders that have been shipped to you.

Eligible Products
The eligible products that may be ordered through the Service (the identity of which are subject to change) are set forth on the product detail page on the Canon Direct website (shop.canon.ca) with the option to select the Service displayed (each, an "Eligible Product"). Your participation in the Service is personal to you, and you may not assign or transfer your enrollment, or any of the benefits of the Service, to any third party without our authorization. The Service is only available to customers with valid shipping addresses in Canada.

Offers, Orders and Returns
Discounts and any limited time promotions associated with the Service apply only to Eligible Products displaying the offer message on the product detail page on the Canon Direct website (shop.canon.ca). Discounts and any amounts from limited time promotions that apply to your order, if any, and which are still in effect, will be automatically deducted from your order.

Some offer details may change as you receive deliveries over time (for example, price, taxes, availability and shipping charges). If an Eligible Product is unavailable when we plan to ship it, we will notify you that we are unable to process your order, and we will wait to process your order until the next scheduled shipping date when the Eligible Product is available. When the Eligible Product becomes available, the price will be the price when you ordered it, regardless of when it becomes available.

Returns of Eligible Products under the Service are subject to our return policy. Service enrollments are void where prohibited.

Enrollment
As part of your enrollment in the Service, you will be required to register with us so that your printer can be identified as participating in the Service. Instructions for registering your printer are contained in the introductory email sent to you after you apply for enrollment in the Service, as well as in the "My Account" section of the Canon Direct website (shop.canon.ca). You will be required to accept terms and conditions provided by our parent company, Canon Inc., as part of registering your printer. Canon Inc. will notify us when an ink or toner cartridge reaches a certain low ink/toner threshold, and we will fill an order for the ink or toner and ship it to you under these Terms. Information provided to us and Canon Inc. may be stored on servers outside of Canada and will be subject to our Privacy Statement. It's possible that your order for Eligible Products will not arrive prior to running out of ink or toner where your use was more than usual, particularly if such greater use occurred over 1 or 2 days.

Payment and Cancellation
The total cost charged to your payment method for each order under the Service will be the cost of the Eligible Product on the day that order is processed, less any discount offered as a percentage or dollars off at the time you registered, plus any applicable sales tax. We reserve the right to modify or cancel any discount offered at the time you registered for the Service, with notice to you, and future orders fulfilled under the Service will reflect any such change.

For each Eligible Product shipped under the Service, you authorize us to charge the payment method used when you enrolled unless otherwise directed by you. If we are unable to complete your order with the payment method you used when you enrolled, we will not fulfill the order and will notify you that your payment method needs to be updated.

Your enrollment in the Service will remain in effect until it is canceled. You can cancel or modify your enrollment at any time via the "My Account" section of the Canon Direct website (shop.canon.ca). If you cancel or modify your enrollment after an order has been processed, you will be charged for the order as processed. If the discount for such Eligible Product changes, the new discount will be applied to your future shipments of that Eligible Product. If, after enrollment, you are no longer in possession of your printer for any reason (e.g., due to warranty return, replacement, or exchange), the total cost for the Service will continue to be charged to your payment method until you cancel your enrollment. No refunds will be granted because of your failure to cancel your enrollment in such situation.

Your rights under these Terms will automatically terminate without notice if you fail to comply with any of its terms and conditions. In the event of such termination, we may immediately revoke your access to the Service. Our failure to insist upon or enforce your strict compliance with these Terms and will not constitute a waiver of any of our rights.

Changes to Terms
We may, in our sole discretion, change these Terms without notice to you. If any change to these Terms is found invalid, void, or for any reason unenforceable, that change is severable and does not affect the validity and enforceability of any remaining changes or conditions. YOUR CONTINUED PARTICIPATION AFTER WE CHANGE THESE TERMS CONSTITUTES YOUR ACCEPTANCE OF THE CHANGES. IF YOU DO NOT AGREE TO ANY CHANGES, YOU MUST CANCEL YOUR ENROLLMENT.

Overview

A Lens to Always Keep by Your Side

Some items like your keys or wallet you just take everywhere you go because you just never know. For anyone with an EOS R series camera, add the RF50mm F1.8 STM lens to that list. As part of the EOS R System, it’s nice and compact thanks to its RF mount so you can shoot – and get a great shot – anywhere and anytime. Size isn’t all though. As a fixed focal length lens, it lets you be creative with composition and can be used for a wide range of scenes from snapshots to portraits, landscapes to low-light situations and more. Those images will stand out, too, just like you intend whether on social media, or when sharing or printing, thanks to impressive optical features like a PMo aspherical lens to suppress aberrations, Super Spectra coating to reduce flaring and ghosting, and a large f/1.8 aperture for low-light shooting and beautiful bokeh. Pick it up and use it one time and you’ll see for yourself, and you won’t be able to leave the house without it.

Compact, Lightweight Fixed 50mm Focal Length Lens.

Being bulky or inconvenient to carry is never a concern with the RF50mm F1.8 STM lens. Its compact size makes it appealing to bring on any trip or excursion and is quite handy to have around, too, with its 50mm fixed focal length letting you be creative with composition and because the 50mm focal length is similar to what the actual human eye sees, it provides a great representation to capture impressive portraits, landscapes, food photos and more.

Large F/1.8 Aperture for Low-Light Photography and Creative Background Blur

The f/1.8 aperture provides you with a number of benefits and options for your photography, including being able to shoot with faster shutter speeds in low light, helping to decrease the effects of camera shake for a more steady shot, reducing the amount of noise in your image, and the ability to beautifully blur the background or foreground depending on your creative taste.

A Stepping Motor (Gear-Type STM) Provides Smooth and Quiet Continuous AF During Video Recording, As Well As When Shooting Photos

The RF50mm F1.8 STM lens uses a gear-type stepping motor to provide smooth and quiet autofocus when shooting both still and video, so focusing appears seamless while following a subject with Servo AF, or Movie Servo AF.  Focus racks will have clean transitions when repositioning to another subject, or when focusing from foreground to background.

Control Ring for Direct Setting Changes**

Standard on all RF lenses, the control ring on the lens barrel enables you to adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the front of the lens and effectively adding a third dial to the EOS R and EOS RP, and a fourth dial for EOS R5 and EOS R6 cameras, the control ring has a tactile, easily distinguished surface so you can grasp and make any setting changes quickly. This ring can also be easily switched to function as a focus ring with the focus/control switch located on the side of the lens, so you can adjust the focus to your desired preference.

Optimized Lens Placement and Coatings Help Deliver Outstanding Colour Balance, While Minimizing Ghosting and Flare

Since you’ll be carrying this lens with you quite often you’ll want something that provides great results. The large diameter and short back focus inherent in all RF lenses helps with image quality while a carefully placed single PMo aspherical lens helps to reduce aberrations at the periphery of the image, with lens coatings further assisting by helping to reduce flaring and ghosting, so your images are clear, vivid and inspiring.

Minimum Focusing Distance of 0.98 Ft. and Maximum Magnification of 0.25x

Capture amazing shots wherever you are and whatever your subject, even at a close distance of 0.98 ft. at a maximum magnification of 0.25x, making this not just an ideal lens for everyday casual shooting but for more intricate shots like food, flowers and smaller subjects you really want to show off.

Circular 7-Blade Aperture Helps Deliver Beautiful, Soft Backgrounds

You’ll have no problem getting that creative, fun and pleasant out-of-focus background blur we all love with the circular 7-blade aperture, so your subject stands out and the background provides a beautiful backdrop that’s visually appealing in itself.

12-pin Communication System

Designed to quickly process data, the 12-pin communication system inherent in all RF lenses helps accelerates autofocusing and more, helping to simplify complex operations and provide a quick and reliable user experience.

Up To 7 Stops* Of Shake Correction with EOS R Series Cameras with In-Body Image Stabilizer

When combined with an EOS R Series camera with In-Body Image Stabilizer, you can experience the benefits of high-precision 5-axis image stabilization even without Optical Image Stabilization so you can capture amazingly clear and steady results while shooting handheld photos or videos, even in low-light situations like indoors or night scenes, without having to significantly increase the ISO or grab a tripod.
