- Zeiss Distagon 21mm f/2.8: Zeiss lenses for Contax/Yashica are of exceptional quality; this one is tops. (Note that Zeiss now makes it in Canon and Nikon mounts.)
- Olympus Zuiko 21mm f/2: This tiny gem of a lens is a less-expensive, high-performance alternative to the Distagon 21mm. And it's fast, too, at f/2.
- Nikon 14–24mm AFS f/2.8G ED: With corner-to-corner sharpness (even wide open), it trounces other lenses in its focal range—even primes.
- Contax N Vario-sonnar T* 17–35mm f/2.8: Many convert this legendary Zeiss lens permanently to a Canon EOS mount.
- Leica Vario-Elmar-R 21–35mm f/3.5–4: Made for the discontinued Leica R SLRs, fans say it's one of the sharpest wide-angle zooms available.
