General Notes on the 16-18-21 Tri-Elmar
This page captures some general impressions and findings from field use.
Why use the Tri-Elmar?
The 16-18-21/4 Tri-Elmar-M is a versatile lens to be used when quick flexibility is needed, or when one needs a 16mm focal length.
- Three focal lengths in one lens only a little larger than the 18/3.8 SEM and 21/3.4 SEM.
- Versatility for conditions in which changing lenses is not viable (hurried shooting, dusty environments, etc).
- A 16mm focal length available with no other Leica M lens.
[Wider DSLR lenses with very high performance can be used via lens adapter on Live View M cameras. See in particular Aperture Series: Backlit Bristlecone Pine (Leica M Typ 240) in Guide to Zeiss.]
