A 60g, 15.3mm thick 28mm f/4.5 full-frame E-mount lens for Sony cameras, designed for ultra-portable wide-angle shooting.

What Buyers Say
The Viltrox AF 28mm F4.5 FE lens surprises many with its incredibly small size and autofocus capabilities for a full-frame E-mount lens, often being mistaken for a body cap. Users frequently highlight its convenience for street and travel photography, appreciating how it makes a full-frame camera jacket-pocketable. While praised for central sharpness and producing pleasing sun stars, some report noticeable corner softness and significant focus breathing during video recording. The fixed f/4.5 aperture and lack of manual focus are consistent points of discussion, limiting its use in low light or for creative depth of field.
“Dude, this thing is literally a lens cap with autofocus! I can actually put my A7C in my jacket pocket now, it's wild. Just wish it wasn't f/4.5 all the time, and the video AF is kinda jumpy, but for $99, I'm not complaining much.”
Common Praise
- Extremely small and lightweight, making the camera setup highly portable.
- Sharpness in the center and mid-frame is consistently reported.
- Autofocus for stills is quick and accurate, even with face and eye detection.
- Produces distinct and attractive sun star effects.
- The innovative slide cap design is convenient and prevents losing a traditional lens cap.
- The ability to update firmware via USB-C is a valued feature.
Common Complaints
- Corners of images can appear soft, especially at wider apertures.
- Significant focus breathing is present, which is distracting in video.
- Autofocus for video can be choppy and pulse, not as smooth as other lenses.
- The fixed f/4.5 aperture limits its use in low-light conditions and for achieving shallow depth of field.
- No manual focus ring or option, which some photographers miss.
- Lack of weather sealing means it's not ideal for all outdoor conditions.
Ownership Tips
- The slide cap is genuinely useful and less prone to being lost than a traditional cap.
- Firmware updates are straightforward via the USB-C port and can improve performance.
- The lack of weather sealing means you really need to be mindful of dust and moisture.
- You'll quickly learn to work around the fixed f/4.5 aperture by adjusting ISO and shutter speed, especially outdoors.
- The absence of filter threads means you can't use ND filters for bright conditions or polarizers for reflections.

Buying Guide
When looking at a lens like this, you're trading off some traditional features for extreme portability. You need to decide if having a camera setup that's barely larger than a body cap is more important than having a variable aperture or manual focus. This lens is about making your full-frame camera an 'always with you' device, not a studio workhorse.
