In this blog, we’ll compare the two lenses side by side to help you determine which one is the best bang for your buck.

Sigma 70-200mm F2.8 DN Sport vs Tamron 70-180mm F2.8 G2 | Which is the Best Bang for Your Buck?

Hi, I’m Dustin Abbott. I had a really narrow window here before I had to send these two lenses back to their respective manufacturers and so I thought I would seize the opportunity of having them both at the same time and do a little bit of head-to-head competition between the brand new Sigma 70-200mm f2.8 DG DN Sports series lens for Sony e-mount and the Tamron 70-180mm f2.8 VC G2 lens also for Sony e-mount. We finally have some quality alternatives to the very expensive $2,800 Sony 70-200mm f2.8 GMaster Mark I lens. While that lens is fantastic, all things being equal, it is the winner between these three, just so you know. But it’s only a winner by a small margin in some areas. These two lenses represent a really good alternative, both amazing lenses, both with some comparative strengths and weaknesses.

Reasons to Choose Tamron

The first of those is price. The Tamron comes to market at a price point of $1,299 while the Sigma is $499, so we do have a $200 difference, which certainly gives the Tamron an advantage if you’re on a tight budget. The advantage for the Tamron is the size, being significantly shorter and lighter than the Sigma. The Tamron also has a higher magnification at 180mm versus 200mm for the Sigma. Tamron has started to implement weather-sealed USBC ports on their lenses, allowing for quick firmware updates and lens customization. Tamron also has fewer controls, but more ability to customize compared to Sigma, allowing for a more tailored setup.

Reasons to Choose Sigma

Sigma has an additional 20mm of focal length, providing more flexibility for various shooting scenarios. It also has better build quality, feeling like a pro-grade lens with premium materials. The Sigma also has more features and controls, including an aperture ring, the ability to declick the aperture ring, and three different custom or function buttons. Overall, the Sigma provides a wider range of controls, making it the equal of the G Master lens in terms of functionality.


Both lenses are really great optical lenses, and as we’re going to see in the image quality breakdown, there’s mostly just give and take between them. The Tamron does have an advantage of having consistently slightly nicer bouquet, while the Sigma has the advantage of additional focal length, better build quality, and more features and controls. Ultimately, the decision between these two lenses may come down to personal preferences and shooting style.
