Voigtländer Color-Skopar 25mm f/4 P

Voigtländer Color-Skopar 25mm f/4 P

Among the smallest wide-angle lenses ever made for the Leica M bayonet, the Color-Skopar 25mm f/4 P is a true pancake that measures only about 30 mm long and weighs around 144 g, leaving it close to a body cap in bulk [1][2]. It arrived in 2007 as a rangefinder-coupled successor to Voigtländer's earlier screw-mount 25mm, the Snapshot-Skopar, which used a scale-focus, click-stop barrel rather than rangefinder coupling. The P version keeps the same optical formula but adds full rangefinder focusing and a redesigned M-mount barrel.

Optically the lens is a seven-element, five-group asymmetrical design using spherical glass, with a slightly concave front element. The aperture runs from f/4 to f/22 in half stops and uses ten blades, which gives ten-point sunstars from point light sources. Construction is almost entirely metal and glass, with an anodized aluminum barrel, a brass focusing helicoid, and a small convex focusing tab; markings are engraved and paint-filled, with the imperial scale picked out in red that can be hard to read in dim light. A distinctive trait is the close focus of 0.5 m, unusually short for an M lens, but because the M coupling cannot track focus that close, the rangefinder couples only down to roughly 0.7 m and the final stretch relies on scale focusing. The front ring is threaded both internally for 39 mm filters and externally for the supplied clip-free hood. As with most 24mm and 25mm M lenses, it brings up the 35mm framelines on Leica M bodies rather than a closer 28mm frame, so most users add an accessory finder for accurate composition.

The lens was sold in black and silver finishes and existed alongside a near-identical 21mm f/4 sibling with similar specifications apart from focal length. Reviewers note that the M-mount P version and the older LTM Snapshot-Skopar are optically the same, with any edge in image quality attributed to updated coatings rather than a new formula. Voigtländer marketed the lens with a small bayonet hood and matching front cap, items worth confirming when buying used.

Optical qualities

Rendering For such a small and modest-aperture lens, the Color-Skopar 25mm is described as delivering a clean, transparent signature with only minor flaws revealing its simple construction.

Sharpness On-axis resolution and contrast are strong even wide open across much of the frame, but there is a clear drop toward the edges, with the outer fifth lacking clarity at f/4. Stopping to f/5.6 improves the outer zones, f/8 brings even performance to the edges, and f/11 is described as optimal apart from slight central softening from diffraction. Sample-to-sample decentering has been observed, with one side weaker than the other.

Contrast and color Global and mid-level contrast are high, though microcontrast lags slightly; the color signature is described as modern and saturated, occasionally lacking subtlety in close tones but generally appealing.

Bokeh and transitions Despite the wide focal length and slow aperture, some subject separation is possible at close distances, and out-of-focus areas are described as reasonably smooth without obvious double-line artifacts, though the effect is limited.

Digital use The lens was designed for film, and on full-frame digital Leica bodies its short rear element and steep ray angles can produce color shifts, most notably a magenta or red color cast along one edge of the frame. This banding is reported on the Leica M10 regardless of aperture, while the lens performs cleanly on film and behaves much better on sensors modified for rangefinder lenses. Buyers intending to use it on digital should weigh this known limitation.

History

Development and Launch Voigtländer, as revived by Cosina, introduced the M-mount Color-Skopar 25mm f/4 P in 2007 to replace its earlier LTM 25mm Snapshot-Skopar. The earlier lens focused by a scale with click stops and was not rangefinder coupled, hence the "snapshot" name; the new version retained the optics but added rangefinder coupling and an M bayonet.

Production Evolution Two distinct versions exist, the original LTM Snapshot-Skopar and the later M-mount P model, which share the same optical design and differ mainly in mount and ergonomics, with possible coating refinements on the newer lens. The lens was produced in Japan and offered in black and silver.

Collector Notes The lens is easily confused with its LTM Snapshot-Skopar predecessor and with the closely related 21mm f/4, so verifying the M mount, the rangefinder coupling, and the focal-length engraving matters. The original bayonet hood, front cap, and a 39 mm filter are worth confirming, and because the barrel is anodized aluminum, scuffs can appear with heavy use. Prospective digital users should be aware of the documented edge color shift before buying.
