The Voigtlander 15mm f/4.5 Heliar III is an ultra-wide angle lens that’s made for Leica M-mount cameras but optimized for full-frame mirrorless cameras. Key features include:
- Update. The Voigtlander 15mm f/4.5 Heliar III is the followup to the popular Voigtlander 15mm f/4.5 Heliar II. It features a new optical formula that improves performance with M-mount cameras, but a large focus was also put on vastly improving performance on mirrorless cameras via adapter.
- Ultra Wide Angle. With an angle of view of 110° with full-frame sensor support, this makes it an ideal choice for large, sweeping landscapes, astrophotography, and some architectural if you don’t mind correcting distortion in post.
- Optics. The updated nine group / eleven element design incorporates one rear aspherical element to combat chromatic aberration and distortion, and vastly reduce color fringing. If you’ve used its predecessor, magenta fringing along the edge of your images was quite bad on both Leica and adapted mirrorless cameras. Luckily, the Heliar III was focused on correcting this.
- Build. The metal construction gives users a very sturdy lens. It features a built-in lens hood for reducing flare, rounded 10-blade aperture, and 58mm filter threads. Being a fully-manual lens, there’s no electronic communication transferred to the camera, so be prepared for empty lens info in EXIF data.
