About the product.
The Lomo T-43 40mm f/4 — the cult triplet lens from the Soviet Smena, here converted to Sony E mount for digital mirrorless. A simple three-element design that renders with gentle, low-contrast tones and a dreamy, swirling character, especially on full-frame sensors. Focuses to infinity, glass is clean, and it’s ready to shoot for that unmistakable Lomo look.
