Comparing Sony’s 28-70mm f/2 GM and Tamron’s 28-75mm f/2.8 Lenses

Choosing the right lens often comes down to balancing performance, features, and cost. If you’ve ever wondered whether investing in a premium lens makes a difference, this comparison between Sony’s 28-70mm f/2 GM and Tamron’s 28-75mm f/2.8 could offer some clarity.

Coming to you from Omar Gonzalez Photography, this detailed video examines the Sony 28-70mm f/2 GM lens alongside the well-loved Tamron 28-75mm f/2.8. The video dives into real-world tests, comparing bokeh quality, sharpness, and build. While the Tamron’s bokeh shows small bubbles in the background, the Sony delivers a cleaner, creamier result. These differences may seem subtle, but for applications like portraits or event photography, they could make a noticeable impact.

One major advantage of the Tamron is its closer minimum focus distance, which allows you to blur backgrounds more effectively in close-up shots. This makes it a practical choice for pseudo-macro work, such as capturing small objects with prominent background separation, like a wedding ring. However, the Sony shines in edge-to-edge sharpness and color control, especially when shooting towards bright light sources like the sun.

The video also touches on usability. The Sony, being a premium lens, is heavier, but lacks features like an aperture ring or custom function buttons, which some may find limiting given its price. In contrast, the Tamron is lightweight and more budget-friendly, making it accessible for those starting out or working within tighter financial constraints. However, the Sony’s f/2 aperture provides a distinct edge in low light and delivers a more pronounced background blur compared to the Tamron’s f/2.8.

Gonzalez raises an interesting point about perfection in lenses. While the Sony is optically flawless, some might prefer the character that less perfect lenses can bring. This preference can matter in creative fields like wedding photography, where an image’s mood might outweigh its technical precision. He also notes that while side-by-side comparisons highlight differences, these distinctions might not be obvious in standalone images. Check out the video above for the full rundown from Gonzalez.
