Viltrox 28mm f4.5 It’s A Compact Companion for the Sony A7C

This lens is mind-blowing! I’ve paired the Viltrox 28mm f4.5 with my Sony A7C, and the results are fantastic.

Shooting with it felt like using a Ricoh GR III full-frame version with my Sony A7C.

While it’s not an f/2.8 lens, the f/4.5 aperture provides impressive subject-to-background separation.

Viltrox 28mm f4.5 Built-In Features and Limitations

Innovative Built-In Cap

One standout feature of the Viltrox 28mm f4.5 is its built-in lens cap. Simply push the lever to open or close it—no more worrying about losing caps for such a small lens.

Fixed Aperture: A Double-Edged Sword

The Viltrox 28mm f4.5 has a fixed f/4.5 aperture.

While this limits versatility, it helps achieve subject separation.

However, an f/11 option would have been ideal for daylight shooting, allowing everything to stay in focus with less effort.

To make the most of this lens, you must carefully set your focus point.


Autofocus Performance

Viltrox 28mm f4.5 it’s very sharp!

The autofocus (AF) on the Viltrox 28mm f4.5 is good but not exceptional.

  • In AF-S (single) mode, the lens hunts slightly. For for macro or close-up shots the hunting is even more obvious (but it’s not a deal break)
  • In AF-C (continuous) mode, it performs much better, faster than the Ricoh GR III and Fujifilm X100VI.

While not as fast as native Sony lenses, the AF of the Viltrox 28mm f4.5 gets the job done for most everyday scenarios.

Image Quality and Sharpness

For a lens of this type, the image quality of the Viltrox 28mm f4.5 is impressive.

  • Sharpness: Good, but focus accuracy is crucial.
  • Contrast: Decent, but flare can reduce it significantly.
  • Vignetting: Strong but easily correctable in Lightroom.

  • Those looking for a compact everyday carry setup
  • Anyone who wants a cost-effective alternative to Ricoh GR III, GR IIIx, or Fujifilm X100VI

By pairing the Viltrox 28mm f4.5 with your Sony camera, you can enjoy the benefits of a full-frame sensor in an ultra-portable package.

After years of using the Ricoh GR III, I find the Viltrox 28mm f4.5 a better compromise:

  • Autofocus: The Viltrox is superior.
