When it comes to compact and budget-friendly lenses, Viltrox has been making waves with its Air series. The latest addition, the Viltrox 25mm F1.7 Air, is designed for Fujifilm X mount APS-C cameras and offers impressive performance at an affordable price.

Lightweight, compact, and sharp, this lens is an excellent choice for travel, street photography, and video work. But does it live up to expectations? Let’s dive into the details.

Build Quality and Design

For a lens in its price range, the Viltrox 25mm F1.7 Air offers surprisingly solid build quality.

  • Material: It’s made from high-quality plastic with a matte black finish and subtle white markings. While it lacks weather sealing, the metal mount gives it a premium touch.
  • Size and Weight: Weighing just 170g, the lens balances perfectly on compact Fujifilm cameras like the X-T5 and X-E4.
  • Focus Ring: The rubber focus ring feels smooth and is well-dampened for precision. It rotates infinitely in both directions due to its electronic design, which adds to the overall ease of use.
  • No Aperture Ring: While it lacks an aperture ring—a common feature in budget lenses—this helps keep the price down without affecting performance.
  • USB-C Port: There’s a USB Type-C port on the mount for firmware updates, ensuring the lens remains future-proof.
  • Filter Thread: The lens features a 52mm filter thread, allowing for easy addition of filters.
  • Minimum Focus Distance: At 30cm, it’s good for capturing detailed close-ups, especially considering the price point.

Autofocus Performance

For a budget lens, the autofocus performance is impressive:

  • Fast and Reliable: Tested on the Fujifilm X-T5, the autofocus proved to be quick and dependable. Out of hundreds of shots, only three were missed—a great result for an affordable lens.
  • Video Autofocus: This is where the 25mm F1.7 Air really shines. It performs exceptionally well in video mode, with no noticeable focus hunting. It even rivals the autofocus of the higher-end Viltrox 13mm F1.4, making it a great option for video creators.
  • Focus Breathing: Minimal to none. This is a significant win for videographers, as it helps maintain consistent framing during focus pulls.

Image Quality: Sharpness and Contrast

The image quality of the Viltrox 25mm F1.7 Air is excellent for its price range.

  • Center Sharpness: The lens is sharp from F1.7 in the center with good contrast and detail.
  • Corner Sharpness: While the corners are slightly softer and show some vignetting, stopping down to F2.8 improves overall sharpness. By F5.6, the image is sharp from edge to edge—perfect even for Fujifilm’s 40MP sensors.
  • Contrast and Colors: The lens delivers vibrant colors and solid contrast, making photos look crisp and dynamic.

Performance at Minimum Focus Distance

At the 30cm minimum focus distance, the lens offers:

  • Slight Softness Wide Open: Images are slightly soft at F1.7, but still retain good contrast and details.
  • Better Results Stopped Down: Stopping down to F2.8 or beyond significantly improves sharpness for close-up shots.

Handling Flare and Chromatic Aberration

  • Flare Control: The lens performs surprisingly well against bright light sources. Flares are minimal, and there’s no noticeable loss of contrast, even when shooting into strong light.
  • Chromatic Aberration: This is where the lens really impresses. There’s no noticeable chromatic aberration or purple fringing wide open—even in challenging conditions. Compared to lenses like the Fujifilm XF 23mm F2, this lens outperforms in terms of chromatic control.
  • Vignetting: Some vignetting is present when shooting wide open, but it’s easy to correct in post-processing or by stopping down.

Why Choose the Viltrox 25mm F1.7 Air?

This lens is ideal for:

  • Travel and Street Photography: Compact, lightweight, and discreet—perfect for shooting on the go.
  • Video Creators: The fast, reliable autofocus and minimal focus breathing make it a great option for video work.
  • Budget-Conscious Photographers: Offering exceptional quality for under $100, it’s a no-brainer for beginners and professionals alike.
  • Fujifilm X Mount Users: Whether you’re using an older model or the latest X-T5, this lens balances beautifully with Fujifilm bodies.
