Wide-angle zoom lenses are a crucial part of the ‘Holy Trinity’ of lenses, offering immense value for various photography genres like landscapes, architecture, and astrophotography. Sometimes, the standard 24-70mm zoom lens doesn’t offer the broad view needed for certain scenes. This is where a wide-angle lens becomes indispensable, filling in the gap below 24mm to capture more in every shot.
Astrophotographers particularly benefit from wide-angle lenses. These lenses can capture more of the sky and allow more light to reach the sensor, which is vital for shooting in low-light conditions. While prime lenses are often recommended for astrophotography due to their wide apertures, a high-quality zoom lens at f/2.8 can also achieve stunning astro shots. The flexibility to change focal lengths with a zoom lens adds versatility for shooting in various styles.
The debate between Sony and Canon lenses is ongoing, often boiling down to personal preference. However, in this comparison, we focus on the Sony FE 16-35mm f/2.8 GM II and the Canon RF 15-35mm f/2.8L IS USM. Each lens has its strengths, and we’ve tested both to see how they stack up against each other. Whether you’re already invested in one of these systems or considering your first full-frame camera and lens setup, this comparison will help you see how these two wide-angle zooms compare.
In September 2023, Sony introduced an updated version of their 16-35mm f/2.8 GM lens, packed with improvements and new features. This lens, when paired with a top-tier mirrorless camera, becomes a powerhouse. One of its most appealing features is its size and weight. Being 35% lighter than its Canon counterpart, it’s easier to handle over long periods and reduces the overall weight of your gear, which is a significant advantage for travelers and those with extensive lens collections.
Our review highlighted the Sony lens’s lightweight nature, despite its high-quality build. Additionally, the lens features a clickable aperture ring, allowing for quick and easy adjustments without diving into camera menus. This is especially handy for cameras with limited control dials. The Sony lens also boasts more aperture blades, a shorter minimum focusing distance, and higher magnification, enabling better close-up shots. Our tests confirmed the lens’s exceptional image quality across various apertures and focal lengths.
Astrophotography performance was impressive, with minimal coma or barreling. While prime lenses are often preferred for astro work, the Sony FE 16.35mm f/2.8 GM II is a solid choice for photographers who dabble in astrophotography alongside other genres. It didn’t make our best lenses for astrophotography list, as the Sony FE 12-24mm f/2.8 GM might be slightly better suited for dedicated astro work, albeit at a higher price.
On the other hand, the Canon RF 15-35mm f/2.8L IS USM lens, despite being older, has its advantages. It offers up to 8 stops of image stabilization when paired with a compatible Canon camera, a feature the Sony lens lacks. This can be a deciding factor for videographers or those who frequently shoot handheld. Our review praised its sleek design and the extra 1mm on the wide end, which, while subtle, can be beneficial for astrophotography. Additionally, the Canon lens has proven its worth over time, maintaining its value and performance.
In conclusion, choosing between these two lenses depends on specific needs and preferences. The Sony FE 16-35mm f/2.8 GM II edges out slightly in terms of specs and practicality for everyday use. However, the Canon RF 15-35mm f/2.8L IS USM holds its ground with image stabilization and a proven track record. It’s a close match, but the Sony lens’s advantages make it slightly more appealing for a broader range of applications.
