Overview

The Leica APO-SUMMICRON-SL 35mm f/2 ASPH is a wide-angle prime built for the L-Mount system, housing 13 elements in 11 groups with five aspherical surfaces and full apochromatic correction. Apochromatic design in this context means the optical formula is engineered to bring red, green, and blue wavelengths to a common focal plane — a correction that eliminates longitudinal chromatic aberration at f/2 where it is most severe in uncorrected designs. The five aspherical elements suppress field curvature and coma across the full frame, so corner sharpness at f/2 approaches center performance in a way that only a few lenses in any format achieve. The floating element group maintains this correction through the entire focusing range down to 27cm, making close-focus rendering as disciplined as the optical behavior at portrait distance.

This lens is designed for professional photographers on the Leica SL, SL2, or SL2-S system — portrait photographers, editorial shooters, and documentary workers who need a wide-angle prime capable of delivering the characteristic Leica 3D rendering at wide apertures without sacrificing color accuracy or edge performance. The Dual Syncro Drive AF is fast enough for event and environmental portrait work, and weather sealing makes it a practical outdoor companion. The combination of focal length and maximum aperture makes this lens the natural choice when a 35mm perspective needs to render with the precision of a macro lens and the subject separation typically reserved for longer primes. It is a lens that rewards commitment to the SL system with a ceiling of optical performance few primes at any price reach.

Key Features

Leica APO-SUMMICRON-SL 35mm f/2 Lens - Front and Rear Lens Caps - Lens Hood - Lens Case

AF System with Dual Syncro Drive - From zero to sharp in no time at all. The Dual Syncro Drive Precision Autofocus allows the Summicron-SL lenses to focus from infinity to the closest focusing distance with exceptional speed and achieving top performance, features important in the professional camera segment.

Two aspherical elements are included in the design to ensure optimum imaging performance across the entire image field.

From the closest focusing distance to infinity, optimum imaging performance is ensured due to the floating lens element.

Each lens offers a special look synonymous with Leica photography with the shallow depth of field, exceptional imaging performance and the 3D "pop" that separates subjects from the background.

Frequently Asked Questions

This lens is natively designed for the Leica L-Mount — it fits the Leica SL, SL2, and SL2-S bodies directly. Through the L-Mount Alliance, it is also fully compatible with Panasonic S-series and Sigma fp bodies without adapters. With Leica's M-Adapter L or third-party L-to-EF/F adapters, it can be mounted on other systems, but AF functionality depends entirely on the adapter's electronic implementation.
Apochromatic (APO) correction means the lens is corrected so that all three primary wavelengths of light — red, green, and blue — converge at the same focal point. In practice, this eliminates the color fringing (longitudinal chromatic aberration) that appears on high-contrast edges at wide apertures. On skin tones especially, APO correction renders transitions more smoothly, with truer color neutrality that requires less post-processing correction.
The Dual Syncro Drive uses two linear motors working in tandem to move the internal focus group from infinity to minimum focus distance with high speed and positional accuracy. In field use on SL2 bodies with Contrast/Phase Detect AF, the system is fast enough for moderately paced subject movement — walking subjects, event photography — at f/2. At the extremely shallow depth of field f/2 provides on a 35mm focal length, the AF's accuracy is more important than its speed, and the Dual Syncro Drive delivers precise focus placement.
The APO-SUMMICRON-SL 35mm f/2 focuses to approximately 0.27m (27cm). The floating lens element adjusts its position relative to the main optical group as focus distance changes, compensating for the aberrations that typically degrade close-focus image quality in fixed-group designs. The result is that optical performance at minimum focus distance remains close to the performance at portrait distances — an important characteristic for detail-oriented product or environmental portrait work.
The APO-SUMMICRON-SL 35mm f/2 ASPH features dust and splash protection as part of Leica's SL lens construction standard. It is not submersible and requires prudent use in heavy rain, but it handles the moisture and dust exposure typical of outdoor portrait, travel, and event work. The included lens hood provides additional front-element protection during shooting.
