Viltrox's ultra-compact 28mm pancake for Sony FE — an incredibly thin manual wide-angle prime.
The Viltrox FE 28mm f/4.5 is an extremely compact pancake wide-angle prime for Sony full-frame E-mount. At just f/4.5, it prioritises compactness over speed, resulting in one of the thinnest interchangeable lenses available. The 28mm focal length provides a useful wide-angle perspective in a package that barely protrudes from the camera body.
Optical performance is acceptable for the extremely compact form factor. Sharpness is respectable when stopped down to f/5.6-8. The slow f/4.5 maximum aperture limits shallow depth of field capability but at 28mm, this is rarely the primary concern. Adequate for street, travel, and casual wide-angle photography where portability is the top priority.
Sony FE mount. Filter thread is very small — typically 37mm or 39mm. Weight is approximately 65 grams — extraordinarily light. Build quality is basic metal construction. The lens is so thin it appears almost flush with the camera body. May lack electronic communication depending on the specific version. No weather sealing or stabilisation.
Available at very low prices. Check for smooth aperture and focus operation. A novelty lens for photographers who value absolute minimum size and weight above all else. The Sony FE 28mm f/2 or Samyang AF 24mm f/2.8 FE are dramatically better choices for anyone who can accept slightly more bulk.
