Lailens 50mm f/1.1

Lailens 50mm f/1.1

The Lailens 50mm f/1.1 is a fast standard lens built for the Leica M mount and aimed at photographers who want a bright fifty at a low cost. It belongs to the wave of inexpensive, manual-focus M-mount optics that have appeared from smaller makers, and it pairs a large f/1.1 maximum aperture with a relatively compact barrel. Reliable collector-grade or technical documentation for this specific lens is currently scarce, so this entry stays close to the recorded specifications and avoids claims that cannot be supported.

Optically the design uses six elements arranged in five groups, a modest count for an f/1.1 standard lens of this size. The barrel measures about 43 mm long, accepts 52 mm front filters, and the lens weighs roughly 386 g, which places it among the more portable fast fifties rather than the heavier double-Gauss designs. The aperture uses thirteen blades, a high count intended to keep the iris opening close to circular as it is stopped down. Minimum focus is 0.7 m. Importantly, the lens is not rangefinder coupled and does not carry six-bit coding, so the focusing helicoid does not drive the camera's rangefinder mechanism; focus on a rangefinder body must be set by scale or estimated distance, while on mirrorless cameras used through an M adapter focus can be confirmed visually with magnification or focus aids. It is offered in black.

Because this is a recent product with limited published history, version differences, finish variations, and identification details are not well documented at this time. No factory special editions are widely recorded.

Optical qualities

Rendering There is little independent, sourced testing of the Lailens 50mm f/1.1, so its rendering cannot be characterized with confidence here. In general terms, the lens is a six-element f/1.1 standard whose thirteen-blade iris is designed to produce a rounded aperture across the stop-down range, and any further description of sharpness, contrast, bokeh, flare, distortion, or aberrations is left out until supported by reliable evidence.
