High-end zoom lenses can make a real difference in the quality of your images. If you’re considering lenses with both versatility and speed, the Sigma 28-105mm f/2.8, Tamron 35-150mm f/2-2.8, and Canon RF 24-105mm f/2.8 are all worth looking at.
Coming to you from Christopher Frost, this thorough video compares three top-tier lenses: the Sigma 28-105mm f/2.8 DG DN Art, Tamron 35-150mm f/2-2.8 Di III VXD, and the Canon RF 24-105mm f/2.8 L IS USM Z. Frost walks through the build quality, performance, and unique features of each lens, providing a detailed side-by-side breakdown. The Sigma is the lightest and least expensive of the group, making it an attractive option for those who prioritize portability and cost. The Tamron, though more expensive and heavier, offers a wider zoom range and excellent sharpness. Then there's the Canon, the most expensive and heaviest of the three. It also provides the widest angle at 24mm, which is helpful for shooting in tighter spaces. This variety makes it clear that no single lens is perfect for every situation, and your choice will depend on your specific needs.
The video highlights the optical performance of these lenses when used on different camera systems. Frost tests the Sigma and Tamron on a Sony a7R III, while the Canon is used with a Canon EOS R5. Each lens delivers excellent sharpness in the center, even at their widest apertures. However, the corners tell a different story. The Tamron stands out for its corner sharpness, while the Canon needs to be stopped down to f/5.6 for optimal results. Vignetting and distortion are also something to keep in mind. Both the Canon and Sigma show significant barrel distortion at their widest angles, which flips into pincushion distortion as you zoom in. Tamron fares better with its more controlled distortion, likely due to its narrower 35mm starting focal length.
One key difference that sets the Canon apart is its built-in image stabilization. While the Sigma and Tamron lack this feature, most modern cameras have built-in stabilization, which can help compensate for this. If you’re using a camera without this function, the Canon may be the better option for handheld shooting. However, its weight makes it less practical for long handheld sessions, especially if you’re covering an event like a wedding.
When it comes to close-up performance, the Tamron can’t get as close as the other two, though it compensates with sharpness when shooting wider. For video work, Frost notes that all three lenses perform admirably, with minimal focus breathing, making them suitable for both photography and videography.
