What these focal lengths actually give you on the OM System OM-3
The OM System OM-3 has a Micro Four Thirds sensor, so it sees a 2× crop of what each lens projects. Every focal length below therefore frames 2× tighter than its marked number. A 50mm on the OM System OM-3 frames like 100mm, not the "normal" view its marked number implies.
| Lens | Marked | Frames like, on the OM System OM-3 |
|---|---|---|
| Panasonic Leica DG 12mm f/1.4 | 12mm | 24mm |
| Panasonic Leica DG 15mm f/1.7 | 15mm | 30mm |
| Panasonic Lumix G 20mm f/1.7 II | 20mm | 40mm |
| Panasonic Lumix G 25mm f/1.7 | 25mm | 50mm |
| OM System M.Zuiko 17mm f/1.8 | 17mm | 34mm |
