Compare the Sigma 24-105mm f/4 Art and Canon EF 24-105mm on mount, aperture, stabilization, and price to choose the right standard zoom for your Canon DSLR.

Quick answer

Choose the Sigma 24-105mm f/4 DG OS HSM Art if you want a constant f/4 full-frame standard zoom for Canon EF DSLRs at a lower catalog price. Choose a Canon EF 24-105mm if you prefer first-party autofocus behavior or plan to move to mirrorless with an adapter. The Sigma covers full frame and crop sensor Canon DSLRs; the Canon is available in EF and RF mounts.

Mount and body fit: what actually works on your camera

The Sigma 24-105mm f/4 DG OS HSM Art Lens Canon Mount is built for Canon EF DSLRs and works on both full-frame and crop-sensor bodies. That makes it a direct fit for cameras like the 5D, 6D, 7D, and 90D series without an adapter. If you shoot a Canon mirrorless body such as an R5 or R6, you will need an EF-to-R adapter, which adds bulk and cost.

Canon's 24-105mm f/4L IS USM comes in EF mount for DSLRs and RF mount for mirrorless. The RF version is native to Canon's mirrorless system and avoids the adapter, but it will not mount on a DSLR. The EF version works on both DSLRs and mirrorless bodies with an adapter. Check which mount your camera uses before buying either lens.

Aperture and stabilization: low-light and handheld shooting

Both lenses use a constant f/4 maximum aperture across the zoom range, so exposure stays consistent when you zoom from 24mm to 105mm. That is useful for event and travel photography where light changes quickly. The Sigma includes Optical Stabilization (OS), which helps reduce shake when shooting handheld at slower shutter speeds.

Canon's 24-105mm f/4L IS USM also includes image stabilization. The practical difference is not the presence of stabilization but how each system performs with your specific body and firmware. If you rely on stabilized video or slow handheld shots, test both on your camera if possible. Neither lens is a substitute for a faster prime in very dark venues.

Price and value: what you pay for each option

The Sigma 24-105mm f/4 Art is listed at USD 957.79, with a catalog comparison price of USD 1349.00. That puts it well below typical first-party f/4 standard zooms and makes it a strong value for Canon DSLR shooters who want a constant-aperture walkaround lens.

Canon's 24-105mm f/4L IS USM pricing varies by mount and condition, so check current listings. The Canon name often carries a higher price for similar core specs. If budget is the deciding factor, the Sigma leaves more room for a second lens or accessory. If you need native RF mount or prefer first-party service and resale, the Canon may justify the difference.

Optical character and real-world use

The Sigma 24-105mm f/4 Art is part of Sigma's Art series, which prioritizes optical performance. It uses a constant f/4 design and covers full frame and crop sensor Canon DSLRs. That makes it a practical one-lens solution for portraits, landscapes, and everyday carry when you want consistent framing without swapping lenses.

Canon's 24-105mm f/4L IS USM is a long-standing workhorse with a similar zoom range and constant aperture. The main differences come down to mount, autofocus behavior with your body, and price. Neither lens is optically perfect at every focal length and aperture, so decide based on the focal lengths and lighting you actually shoot.

Trade-offs at a glance

Sigma 24-105mm f/4 Art: price vs first-party convenience: Lower catalog price (USD 957.79 vs comparison price USD 1349.00) and dual full-frame/crop-sensor Canon DSLR compatibility. Trade-off: not a native RF mount lens, so mirrorless users need an adapter. Best value if you shoot a Canon DSLR and want a constant f/4 standard zoom.
Canon EF 24-105mm f/4L IS USM: native mount vs cost: Available in EF and RF mounts, with the RF version avoiding an adapter on Canon mirrorless. Trade-off: typically higher price and the RF version will not fit a DSLR. Choose Canon if native mount, first-party service, or resale matter more than price.
Focal range overlap: one lens vs a system: Both 24-105mm options cover wide to short telephoto. If you also need ultra-wide, the Sigma 12-24mm f/4 Art or 14-24mm f/2.8 Art cover wider angles but do not replace the 24-105mm range. Decide whether you need one do-it-all zoom or a two-lens kit with an ultra-wide.

Product facts

Sigma 24-105mm f/4 DG OS HSM Art Lens Canon Mount: The Sigma 24-105mm F/4 DG OS HSM Lens is a wide-angle to medium telephoto zoom lens with a constant f/4 aperture. It is designed for both full frame and crop sensor Canon DSLR cameras. A constant f/4 aperture keeps exposure consistent while zooming, and the dual-format design means one lens works on both full-frame and crop-sensor Canon DSLRs.
Sigma 12-24mm f/4 DG HSM Art Lens Canon EF Mount: The Sigma 12-24mm F/4 DG HSM | Art Lens is an ultra-wide-angle zoom lens that is perfect for ultra-high resolution, full frame cameras. It offers an optimal package of centre-to-edge image quality, minimized distortion, and minimum focusing distance. If your work leans toward architecture or tight interiors rather than a standard zoom, this ultra-wide Art lens covers a different need and is not a direct replacement for a 24-105mm.
Sigma 14-24mm f/2.8 DG HSM Art Lens Canon Mount: With an ultra-wide zoom lens with a constant f/2.8 aperture, the Sigma 14-24mm f/2.8 DG HSM Art Lens is an outstanding option for architectural and landscape shooters with full-frame Canon EF cameras. A part of the esteemed Art-series of lenses, a sophisticated optical design is used that incorporates three FLD, three SLD, and three aspherical elements to help reduce chromatic aberrations and keep distortion under... A faster f/2.8 ultra-wide is a complement to a 24-105mm when you need more light and a wider field of view, not a substitute for the standard zoom range.
