Leica APO-Summicron-SL 35 f/2 ASPH: An Overview

1. Purpose and Versatility:

   • The APO-Summicron-SL 35mm f/2 ASPH is a moderate wide-angle prime lens designed for the Leica SL system.
   • Its versatility makes it suitable for various genres of photography, including reportage, architecture, landscapes, portraiture, and studio work.
   • Whether you're capturing the bustling streets of a city or the serene beauty of a landscape, this lens has you covered.

2. Optical Construction:

   • The lens comprises 11 lenses arranged in 9 groups.
   • Among these, three lenses feature aspherical surfaces, while three are made of glass with anomalous partial dispersion.
   • These special optical properties help compensate for chromatic aberrations, ensuring exceptional image quality.

3. Aperture and Depth of Field:

   • With a maximum aperture of f/2, the APO-Summicron-SL 35mm strikes a balance between light-gathering capability and compactness.
   • Even at this aperture, it allows for a shallow depth of field, emphasizing your subject while beautifully blurring the background.

4. Autofocus System:

   • The autofocus system employs Dual Syncro Drive™ technology, resulting in fast, precise, and nearly silent focusing.
   • The lens transitions from infinity to the closest focusing distance swiftly, ensuring you capture the decisive moment without delay.

5. Optical Coatings and Stray Light Prevention:

   • Leica engineers meticulously optimized the lens design to minimize stray light and reflections.
   • High-quality optical coatings on lens surfaces reduce unavoidable reflections to the lowest possible level.

6. Manual Focusing Experience:

   • The manual focusing ring introduces a novel concept.
   • A ring magnet with alternating north-south magnetization is embedded in the focusing ring.
   • As you turn the ring, the magnetic field changes polarity, and a sensor relays this data to the main processor.
   • The lens then shifts to the corresponding focusing position based on the angle of rotation and rotational speed.
   • This innovative approach ensures precise manual focus control.

7. Compactness and Feel:

   • Despite its impressive optical performance, the APO-Summicron-SL 35mm remains compact and lightweight.
   • It weighs just 13.05 ounces (370 grams), making it a joy to carry and use.
   • The lens also boasts excellent grip and tactile feel, enhancing the shooting experience.

In summary, the Leica APO-Summicron-SL 35 f/2 ASPH is more than just a lens—it's a creative tool that empowers photographers to express their vision with exceptional clarity and precision¹². Whether you're a seasoned professional or an enthusiastic hobbyist, this lens promises to elevate your photography to new heights!
