Zonlai 25mm f/1.8 Review

The Zonlai 25mm f/1.8 is a fast prime lens for Micro Four Thirds cameras, offering a 50mm full-frame equivalent field of view and a wide aperture for shallow depth of field and low-light shooting. At $450, it sits in the mid-range of the MFT lens market, competing with options from Panasonic, Olympus, and other third-party manufacturers.

Zonlai has built a reputation for affordable manual-focus primes, and this 25mm represents a step up in both focal length popularity and price point. The f/1.8 aperture should provide solid subject separation and background blur for portraits, street photography, and everyday shooting on MFT bodies. Build quality and optical performance remain to be seen, as does how it stacks up against established alternatives like the Panasonic Lumix G 25mm f/1.7 or Olympus M.Zuiko 25mm f/1.8, both of which offer autofocus at similar or lower price points. Manual-focus shooters looking for character and value in a normal prime may find this worth exploring once real-world performance is documented.
