If you’ve been eyeing a budget-friendly telephoto lens for your mirrorless setup, the Canon RF 75-300mm might just be the affordable answer. Canon has officially announced this new RF-mount telephoto zoom as their cheapest native full-frame option yet, designed for amateur wildlife, sports, and outdoor photographers who want greater reach without breaking the bank.

Canon RF 75-300mm Offers Budget-Friendly Telephoto Performance

Priced at just £289 in the UK, the Canon RF 75-300mm f/4-5.6 lens undercuts every other full-frame telephoto option in Canon’s mirrorless RF line-up. In fact, the only cheaper RF lens overall is the ultra-budget Canon RF 50mm f/1.8 STM—also known as the nifty fifty. That makes the new 75-300mm an intriguing choice for those wanting to expand into telephoto territory on a shoestring.

While US pricing hasn’t yet been announced, it’s expected to follow suit with affordability at its core. The lens brings significant reach to Canon EOS R users, including those shooting on full-frame bodies like the Canon EOS RP, as well as APS-C models such as the EOS R50 or R100. On a crop-sensor camera, the lens provides an effective focal range of 120-480mm, making it ideal for photographing distant subjects like birds, wildlife, or sporting action.

Compact and Lightweight for On-the-Go Shooting

One of the most surprising features of the Canon RF 75-300mm is its compact, lightweight design. Weighing in at just 507g (17.9oz), it’s refreshingly easy to carry compared to most telephoto options. With a length of 146.1mm when retracted, it fits comfortably in a standard camera bag and won’t be a burden on long shoots or hikes.

Despite its affordability and size, the lens still offers a solid construction with 13 glass elements arranged in nine groups. It features a seven-blade diaphragm, which Canon says delivers attractive, circular bokeh—perfect for isolating subjects in portrait or wildlife photography. Canon also applies its Super Spectra Coating to reduce ghosting and lens flare, further improving image quality in bright or backlit conditions.

Key Features of the Canon RF 75-300mm

  • Focal Length: 75–300mm (120–480mm equivalent on APS-C)

  • Maximum Aperture: f/4–5.6

  • Weight: 507g

  • Length: 146.1mm

  • Autofocus: DC motor-driven

  • Minimum Focusing Distance: 1.5 metres

  • Lens Construction: 13 elements in 9 groups

  • Aperture Blades: 7

  • Image Stabilisation: None

One notable omission is the lack of in-lens image stabilisation. While this might be a dealbreaker for some, especially when shooting handheld at longer focal lengths, Canon likely dropped this feature to keep the price as low as possible. Many EOS R-series bodies have in-body stabilisation anyway, which can help offset this absence.

How It Compares to Other Canon Telephoto RF Lenses

The Canon RF 75-300mm finds its place amongst a growing roster of budget and mid-range RF-mount telephoto lenses. Other options like the Canon RF 100-400mm f/5.6-8 IS USM and the RF-S 55-210mm f/5-7.1 IS STM offer built-in stabilisation and different zoom ranges, but come at a slightly higher price. Meanwhile, more specialised lenses like the RF 600mm f/11 IS STM and RF 800mm f/11 IS STM deliver extreme reach but lack versatility and fast apertures.

Interestingly, this new RF lens shares its specifications closely with Canon’s older DSLR model—the EF 75-300mm f/4-5.6 III. However, being native to the RF mount, it avoids the need for adapters and benefits from improved compatibility with mirrorless autofocus systems.

Who Should Buy the Canon RF 75-300mm?

This lens is clearly aimed at entry-level and enthusiast photographers who want to explore telephoto photography without splurging. It’s a fantastic companion for:

  • Wildlife photographers capturing birds or animals from a distance

  • Amateur sports photographers needing reach for field coverage

  • Travel or hiking photographers seeking a lightweight zoom solution

  • Beginners building their first mirrorless kit on a budget

While professionals may miss features like image stabilisation or faster focusing motors, the Canon RF 75-300mm is not trying to compete at the high end. Instead, it fills a much-needed gap in Canon’s mirrorless ecosystem for casual shooters and hobbyists.

Final Thoughts on Canon’s Cheapest RF Telephoto Lens

Canon’s release of the RF 75-300mm demonstrates a welcome commitment to affordability in the mirrorless market. At a time when many photographers feel priced out of upgrading, this lens makes telephoto zoom accessible once again.

If you’re looking to expand your creative options with a lens that delivers long reach in a lightweight and budget-conscious form, the Canon RF 75-300mm deserves a spot on your shortlist.
