Leica Summarit M 50mm f/2.5 Lens - Premium Compact Prime Lens for Leica M Mount Cameras | Perfect for Street, Portrait & Travel Photography

The smallest new Summarit-M

The 50 mm Summarit-M is tailor-made for everyday photography. Its lens speed is perfectly adapted for all common applications. It is an updated double-Gauss six-element construction based on our tried and tested design. All of this means that this particular Summarit-M makes the Leica M easier to experi ence than ever before, without cutting any corners in terms of optical performance.

Convincingly realistic perspective 

Not just beneficial for portraits, but for all shots at full aperture, the shallow depth of field of this lens makes the main subject stand out from the background. This results in pictures with enhanced impact and out-of-focus areas that have a pleasant, natural smoothness.

Small on the outside, quality on the inside

Even at full aperture, the lens offers outstanding results with excellent contrast over almost the entire image field. At the extreme edges of the field – which are not captured by the slightly smaller format of the digital LEICA M8 – the performance can be improved by stopping down to 5.6. Even at close range, these excellent results are largely maintained.

Optimum image correction

The LEICA SUMMARIT-M 50 mm f/2.5 has a traditional double-Gauss construction made up of six lens elements in four groups, arranged symmetrically. As a result, it provides an outstandingly flat image field and excellent correction for chromatic aberrations and distortion.

Maximum measurable vignetting in the corners of the field is around 1.7 stops at full aperture in the 35 mm format. Stopping down to 5.6 significantly reduces this light falloff at the periphery of the image to around to stop. On the digital LEICA M8, it is compensated automatically. The very slight pincushion distortion is negligible in almost all applications.
