Build Quality and Design
When I first handled the Sigma 24-70mm f/2.8, I was immediately impressed by its solid construction. This lens feels substantial in your hands, with a high-quality build that exudes professionalism. The barrel is made of a combination of Thermally Stable Composite (TSC) and metal, which I’ve found provides excellent durability without adding unnecessary weight. The weather sealing is impressive, with rubber gaskets at all connection points, which I’ve appreciated on numerous occasions when shooting in challenging conditions.
The Sony 24-105mm f/4, on the other hand, has a more refined feel. It’s noticeably lighter than the Sigma, which I found beneficial during long photography sessions. The build quality is excellent, with a metal mount and high-quality plastics elsewhere. Like the Sigma, it features weather sealing, though I’ve noticed the Sony’s sealing feels slightly less comprehensive than the Sigma’s.
In terms of ergonomics, both lenses are comfortable to handle, but I’ve found the Sony’s zoom ring to be slightly smoother and more damped. The Sigma’s focus ring is well-positioned and provides good resistance, while the Sony’s focus ring is electronically coupled and offers a more precise feel when manually focusing.
One design difference I’ve noticed is that the Sigma extends significantly when zooming to 70mm, while the Sony maintains a more consistent length throughout its zoom range. This internal zoom design of the Sony can be advantageous when shooting in dusty environments, as it reduces the chance of dust entering the lens.
Optical Performance
Sharpness
When it comes to sharpness, both lenses perform admirably, but with some differences. I’ve found the Sigma 24-70mm f/2.8 to be exceptionally sharp across the frame, even when shooting wide open at f/2.8. In my tests, the center sharpness is outstanding from wide open, with only slight softening in the corners at 24mm. By f/4, the corners sharpen up nicely, and the lens delivers excellent performance across the frame.
The Sony 24-105mm f/4 is also impressively sharp, particularly in the center. At f/4, it delivers excellent center sharpness, though I’ve noticed the corners can be a bit soft at 24mm. Stopping down to f/5.6 or f/8 improves corner performance significantly. At the longer end of the zoom range (105mm), the Sony maintains good sharpness, though not quite at the level of the Sigma at 70mm.
In real-world shooting, I’ve found both lenses produce sharp, detailed images that hold up well to pixel-peeping. However, if you’re looking for the absolute best sharpness wide open, the Sigma has a slight edge.
Distortion and Vignetting
Both lenses exhibit some distortion and vignetting, which is typical for zoom lenses in this range. I’ve discovered that the Sigma 24-70mm f/2.8 shows moderate barrel distortion at 24mm, transitioning to slight pincushion distortion at 70mm. The vignetting is noticeable at f/2.8, especially at 24mm, but improves significantly when stopped down to f/4.
The Sony 24-105mm f/4 also exhibits barrel distortion at 24mm, though I’ve found it to be slightly less pronounced than the Sigma. At the telephoto end, there’s minimal distortion. Vignetting is present at f/4, particularly at 24mm, but again, it’s less severe than what I’ve observed with the Sigma wide open.
The good news is that both lenses have distortion and vignetting correction profiles available in most modern editing software, including Sony’s own Imaging Edge and Adobe Lightroom. I’ve found that applying these corrections effectively eliminates these issues, making them a non-factor for most practical purposes.
Chromatic Aberration
Chromatic aberration (CA) is an area where I’ve noticed a difference between these two lenses. The Sigma 24-70mm f/2.8 shows some lateral CA, particularly at the edges of the frame when shooting high-contrast scenes. However, I’ve been impressed by how well-controlled longitudinal CA is, even when shooting wide open.
The Sony 24-105mm f/4 handles CA exceptionally well, with minimal lateral CA and very well-controlled longitudinal CA. In my experience, the Sony’s CA performance is slightly better than the Sigma’s, particularly in challenging lighting conditions.
That said, both lenses perform well enough that CA is rarely an issue in real-world shooting. When it does appear, it’s easily correctable in post-processing.
Bokeh Quality
The quality of background blur (bokeh) is where these lenses differ significantly due to their aperture differences. The Sigma 24-70mm f/2.8, with its wider maximum aperture, can produce much creamier, more pronounced bokeh. I’ve found that the Sigma renders out-of-focus areas smoothly, with pleasing circular highlights and minimal nervousness.
The Sony 24-105mm f/4, with its narrower maximum aperture, produces less background blur at the same focusing distance. However, I’ve discovered that the bokeh quality is still quite good, with smooth rendering and well-controlled highlights. The 9-blade aperture helps maintain circular bokeh shapes when stopped down a bit.
For portrait work or situations where subject separation is important, the Sigma’s f/2.8 aperture provides a clear advantage. However, for landscape or architectural photography where edge-to-edge sharpness is more critical, the Sony’s performance is excellent.
Autofocus Performance
Autofocus performance is crucial for many photographers, and both lenses deliver in this area, though with some differences. The Sigma 24-70mm f/2.8 uses a stepping motor for autofocus, which I’ve found to be fast, quiet, and accurate. When shooting portraits or events, the Sigma locks onto subjects quickly and maintains focus well. In continuous autofocus mode, it tracks moving subjects competently, though not quite at the level of Sony’s native lenses.
The Sony 24-105mm f/4 utilizes a linear motor for autofocus, and I’ve been consistently impressed by its performance. The autofocus is lightning-fast, virtually silent, and extremely accurate. When shooting sports or wildlife, the Sony’s tracking capabilities are excellent, maintaining focus on moving subjects with remarkable consistency.
One area where I’ve noticed a significant difference is in low-light autofocus performance. The Sony 24-105mm f/4 maintains its autofocus speed and accuracy even in dim lighting conditions, while the Sigma can sometimes hunt slightly in very low light.
For video work, both lenses offer smooth autofocus performance, but the Sony has the edge with its quieter operation and more natural focus transitions. If you shoot a lot of video, particularly with autofocus, the Sony might be the better choice.
Low-Light Capabilities
When it comes to low-light performance, the Sigma 24-70mm f/2.8 has a clear advantage due to its wider maximum aperture. That full stop of light (f/2.8 vs. f/4) makes a significant difference in dim conditions. I’ve found that when shooting indoor events or evening scenes, the Sigma allows me to use lower ISO settings or faster shutter speeds, resulting in cleaner images.
The Sony 24-105mm f/4, while not as capable in extreme low light, still performs reasonably well thanks to its excellent optical stabilization (more on that next). In moderate low-light situations, I’ve been able to get good results by slightly increasing the ISO or using slower shutter speeds.
For astrophotography or night scenes where you need to capture as much light as possible, the Sigma’s f/2.8 aperture provides a distinct advantage. However, for general low-light photography, both lenses can produce excellent results with proper technique.
Image Stabilization
This is one area where the Sony 24-105mm f/4 has a clear advantage over the Sigma. The Sony features Optical SteadyShot image stabilization, which I’ve found to be exceptionally effective. In my tests, I’ve been able to get sharp handheld shots at shutter speeds as slow as 1/15s at the wide end and 1/30s at the telephoto end. This makes a huge difference when shooting in low light or when you need to maintain depth of field without increasing ISO.
The Sigma 24-70mm f/2.8 lacks optical stabilization, relying instead on the in-body stabilization (IBIS) of Sony cameras. While modern Sony cameras have excellent IBIS, I’ve found that the combination of lens-based stabilization and IBIS in the Sony 24-105mm f/4 provides superior stabilization performance, particularly at longer focal lengths.
For video work, the Sony’s stabilization is even more valuable, providing smooth, stable footage even when shooting handheld. If you shoot a lot of video or frequently work in low light without a tripod, the Sony’s image stabilization alone might be worth the extra cost.

Versatility and Range
The range difference between these two lenses is significant, with the Sony offering 35mm more reach at the telephoto end. I’ve found this extra versatility to be invaluable in many shooting situations. When traveling, the Sony’s 24-105mm range covers most scenarios, from wide landscapes to tighter portraits and even some wildlife shots.
The Sigma’s 24-70mm range is more limited, though it does cover the most commonly used focal lengths for general photography. I’ve found that for event photography, portraits, and landscapes, the Sigma’s range is usually sufficient. However, when I need that extra reach, I’ve missed having the 105mm option.
The versatility advantage goes to the Sony, not just because of the extra reach, but also because of its lighter weight and more compact size. When hiking or traveling light, I’ve found the Sony to be a more convenient all-in-one solution.
Price and Value
When considering price, the Sigma 24-70mm f/2.8 typically retails for around $1,099, while the Sony 24-105mm f/4 goes for approximately $1,298. While the Sony is more expensive, I believe both lenses offer good value for money considering their performance and features.
The Sigma provides excellent optical quality and a wide f/2.8 aperture at a competitive price point. If you prioritize low-light performance and subject separation, the Sigma offers tremendous value.
The Sony, while more expensive, brings image stabilization, greater reach, and native lens compatibility to the table. For photographers who value versatility and stabilization, the Sony justifies its higher price tag.
It’s worth noting that both lenses hold their value well on the used market, so whichever you choose, you can expect to recoup a reasonable portion of your investment if you decide to sell later.
