Updated July 2026 — full head-to-head comparison.

Price Comparison

When it comes to price, the Tamron 24mm F/2.8 Di III OSD M1:2 Lens is about 17% cheaper than the Canon RF28mm F2.8 STM Lens, retailing for $199.00 compared to Canon's $299.00. This significant price difference may appeal to budget-conscious photographers looking for a reliable wide-angle option. While both lenses deliver excellent performance, the lower cost of the Tamron lens makes it an attractive choice for those who are just starting with wide-angle photography or who want a versatile lens without breaking the bank.

Design and Build Quality

In terms of design, both lenses are compact and lightweight, but the Tamron 24mm lens is notably lighter at 7.6 ounces compared to the Canon's slightly heftier build. The Tamron's length of 2.5 inches makes it easy to carry during all-day shooting adventures, while the Canon lens's pancake design is also super-compact and easy to handle. Additionally, the Tamron features a Moisture-Resistant Construction and a Fluorine Coating that helps resist dirt, providing an edge for outdoor photography in various conditions. This added durability may be particularly appealing for photographers who often shoot in the great outdoors.

Image Quality

Both lenses excel in delivering high-quality images, but they have different focal lengths that cater to varying needs. The Canon RF28mm F2.8 STM Lens provides a 28mm coverage ideal for street photography and video, while the Tamron 24mm F/2.8 lens offers a wider angle, making it great for landscapes and urban scenes. The Canon lens benefits from three aspheric elements and Canon's Super Spectra Coating to minimize ghosting and flare. Conversely, the Tamron lens incorporates special glass materials, including Low Dispersion and Glass Molded Aspherical elements, to enhance optical performance and minimize aberrations. This focus on image quality ensures that both lenses can produce stunning visuals, though they cater to slightly different creative preferences.

Focusing and Usability

Focusing capabilities differ between the two lenses, with the Canon featuring a Canon leadscrew type STM focus drive, which is particularly advantageous for smooth and quiet video autofocus operation. This can be a significant factor for videographers who prioritize audio clarity during recording. The Tamron lens, on the other hand, allows for a 1:2 maximum magnification ratio, enabling detailed macro-style shots with a minimum object distance of just 4.7 inches. This feature opens up creative possibilities for photographers looking to capture unique close-up shots, making the Tamron lens an enticing option for those who enjoy experimenting with perspective.

Versatility

The Tamron 24mm lens stands out for its versatility, suitable for both full-frame and APS-C E-Mount mirrorless cameras. Its wide-angle field of view makes it ideal for various shooting styles, from candid snapshots to expansive landscapes. The Canon RF28mm lens is also compatible with APS-C sensor EOS R-series cameras, providing coverage equivalent to a standard 45mm lens. While both lenses serve a wide range of photography styles, the Tamron's broader appeal due to its unique close-up capabilities and lightweight design may attract photographers who appreciate a do-it-all lens.

Target Audience

The Canon RF28mm F2.8 STM Lens is tailored for photographers who value a compact design and smooth video performance, particularly those using full-frame EOS R series cameras. It serves as an excellent entry point for those looking to explore wide-angle photography without overwhelming complexity. The Tamron 24mm F/2.8 lens, with its affordable price and versatile features, is perfect for everyday photographers and adventurers who want a lightweight lens that can handle a variety of shooting situations. This makes the Tamron a better fit for those who prioritize portability and casual use.

Availability and Market Position

Both lenses are widely available, but the Canon RF28mm F2.8 STM Lens may have a stronger brand recognition within the Canon user community. While neither lens has a definitive bestseller rank, the lower price and versatility of the Tamron lens position it well in the market, appealing to a broader audience. Canon's legacy and reliability might sway dedicated Canon users, but Tamron's competitive pricing and features make it a compelling alternative for those considering their first wide-angle lens.

Which should you buy?

Ultimately, the choice between the Canon RF28mm F2.8 STM Lens and the Tamron 24mm F/2.8 Di III OSD M1:2 Lens comes down to your specific photography needs and budget. If you seek a lightweight lens with unique close-up capabilities and an attractive price point, the Tamron lens is a clear winner, priced at $199. However, if you prefer a lens that excels in video autofocus and provides excellent image quality with a slightly wider field of view, the Canon lens may be worth the additional investment at $299. Each lens has its strengths, so consider your priorities to determine which option aligns best with your photography style.
