"The Canon RF 100-300mm f/2.8 L IS USM is one of those lenses that feels purpose-built for real-world shooting. The constant f/2.8 aperture across the zoom range makes it brilliant for indoor sport, theatre and low-light events, while the stabilisation and autofocus keep up even when you are working hand-held or on a monopod."

Product description
Rent a Canon RF 100-300mm f/2.8 L IS USM when you need a fast, professional telephoto zoom that covers everything from tight portraits to indoor arenas. This lens is designed for Canon’s full-frame RF-mount cameras and gives filmmakers and photographers a bright, consistent f/2.8 aperture across the entire zoom range.
The Canon RF 100-300mm f/2.8 L IS USM essentially brings prime-level optics into a flexible zoom package. Instead of swapping between multiple fast telephoto primes, you can track the action from 100mm through to 300mm while maintaining shallow depth of field and excellent subject separation. It is particularly appealing for indoor sports, fashion shows, theatre productions and concerts, where you often have to react quickly to changing positions and lighting.
Optically, the lens uses an advanced design with fluorite, aspherical and Ultra-Low Dispersion elements to keep contrast high and chromatic aberrations low throughout the range. Canon’s modern coatings help control flare and ghosting under stage lighting or backlit conditions. The Dual Nano USM autofocus system is quick, precise and near-silent, making this an excellent option for video as well as stills. Add in effective optical image stabilisation, internal zoom and focus, and full RF Extender compatibility, and you have a robust professional tool that slots neatly into a modern Canon RF kit for camera rental in Canada.

Optical performance, autofocus and stabilisation
The Canon RF 100-300mm f/2.8 L IS USM has been engineered to deliver crisp results across the entire zoom range. Its complex optical formula, including fluorite, aspherical and multiple UD elements, keeps fine detail sharp from centre to corner while limiting colour fringing on high-contrast edges. The constant f/2.8 aperture gives you real control over depth of field, making it easier to isolate subjects against busy backgrounds in arenas, theatres or outdoor venues. Combined with Canon’s sophisticated coatings, the lens holds up well against stage lights, backlighting and reflective surfaces, which is especially useful for video and live events.
Autofocus is driven by a Dual Nano USM system, combining very fast response with smooth, virtually silent operation. This is ideal for both high-speed stills bursts and video work where focus transitions need to be precise but unobtrusive. The internal focusing and zoom design helps the lens maintain its length, which is excellent for gimbal balance and general handling. Optical image stabilisation provides up to 5.5 stops of shake reduction on its own, and up to roughly 6 stops when paired with in-body stabilisation on compatible EOS R cameras, helping you keep shots steady at longer focal lengths or slower shutter speeds. Focus presets, a focus limiter and configurable lens function buttons give you extra control for tracking fast-moving subjects.
Why rent the Canon RF 100-300mm f/2.8 L IS USM?
The Canon RF 100-300mm f/2.8 L IS USM is an excellent rental choice for anyone shooting sport, wildlife in controlled environments, stage performances, fashion shows or live events on Canon RF bodies. Instead of juggling multiple primes, you gain a highly usable zoom range with a constant f/2.8 aperture, all in a package that balances well on modern mirrorless cameras. It works equally well for handheld work, monopod setups, or mounted on a tripod with its rotating collar, and its internal zoom mechanism makes it easier to keep rigs balanced on gimbals and support systems.
For filmmakers and hybrid shooters, the combination of quiet autofocus, strong stabilisation and consistent optical performance makes this lens a very practical tool. The colour rendering matches Canon’s L-series look, and the shallow depth of field at f/2.8 helps your subject stand out in busy environments. For photographers, it shines at indoor arenas, pools, courts and theatres where you may be working at the edge of available light and need every bit of aperture and stabilisation you can get.
Rent a Canon RF 100-300mm f/2.8 L IS USM from Canada Camera Rentals and get a fast, flexible telephoto zoom that keeps pace with demanding professional work whilst remaining portable enough for travel and multi-location shoots.
Q&A
The Canon RF 100-300mm f/2.8 L IS USM includes an optical image stabiliser rated for up to around 5.5 stops of shake reduction on its own, and up to roughly 6 stops when paired with in-body stabilisation on compatible EOS R cameras. In practice, this means you can work hand-held at longer focal lengths or slower shutter speeds than you could without stabilisation, which is particularly helpful for indoor events and available-light work.
The Canon RF 100-300mm f/2.8 L IS USM is designed exclusively for Canon RF-mount bodies, so it works with full-frame EOS R cameras such as the EOS R3, R5, R6 series and other RF-mount models. It is not directly compatible with older EF-mount DSLRs, and Canon does not offer an official adapter to mount this RF lens on EF bodies, so you will want to pair it with an RF camera when you rent it in Canada.
Yes, the RF 100-300mm f/2.8 L IS USM is particularly well suited to indoor sport, theatre, concerts and event work. The constant f/2.8 aperture lets in plenty of light, helping keep shutter speeds high enough to freeze action, while the stabilisation and fast autofocus help you track moving subjects. The zoom range allows you to frame tightly from the stands or the back of a venue without needing to change lenses mid-action.
Yes, the Canon RF 100-300mm f/2.8 L IS USM is compatible with the Canon RF 1.4x and RF 2x Extenders. With the RF 1.4x Extender you gain extra reach with a modest reduction in maximum aperture, while the RF 2x Extender doubles the focal length range for situations where you need even tighter framing. Do bear in mind that extenders reduce light transmission and can slightly impact autofocus performance, so they are best used in reasonably bright conditions.
Although the lens is designed for professional use and handles well, it is still a substantial piece of glass, so many shooters prefer a monopod or tripod for longer sessions. The built-in rotating tripod collar makes it easy to mount on supports and switch quickly between landscape and portrait orientation. For video, pairing it with a sturdy monopod or fluid head can make tracking movement smoother and less tiring over a long day.
