Leica's later R standard zoom — the manual-focus Vario-Elmar-R 35-70mm f/4, a compact constant-aperture zoom.
The Leica Vario-Elmar-R 35-70mm f/4 is a later standard zoom for the Leica R reflex system, covering the everyday moderate-wide to short-telephoto range at a constant f/4 maximum aperture. It followed the earlier f/3.5 design and gave R users a compact walk-around zoom for general photography. It is distinct from the f/3.5 version in aperture and construction.
This is a manual-focus Leica R lens covering 35-70mm with a constant maximum aperture of f/4 across the range. It is a full-frame reflex standard zoom introduced later in the R line. Buyers should confirm the filter thread and cam configuration on the specific example and take care to distinguish it from the earlier f/3.5 version, which is a separate lens.
The 35-70mm span covers wide framing at 35mm, the natural 50mm view and short-telephoto portraits at 70mm in one lens. The constant f/4 aperture holds exposure steady through the zoom. It suits travel, landscape, portrait and general use for photographers who want a single flexible optic rather than a set of primes.
On the used market this f/4 version turns up less often than the f/3.5 and is regarded as a competent later R zoom. Check the zoom and focus actions are smooth, look for internal haze, fungus and dust, and confirm the aperture operates cleanly. Verify the cam setup for correct metering on your R body, and be sure which version you are buying; a Leica R adapter allows mirrorless use.
