Leica APO-Summicron-M 75mm f/2 ASPH. Model 11637.

Overview:
The Leica APO-Summicron-M 75mm f/2 ASPH. is a portrait-length lens designed for Leica M-mount rangefinder cameras. It combines optical excellence with a compact form factor, making it a favorite among discerning photographers. Here are the key details:

1. Apochromatic Design:

   • The "APO" in its name stands for apochromatic, which signifies its advanced optical design.
   • It utilizes one fluorite element and one anomalous partial dispersion glass element to virtually eliminate chromatic aberrations and color fringing. This results in exceptional clarity and color accuracy across the entire aperture range.
   • An aspherical element made from high refractive index glass further controls spherical aberrations, ensuring sharpness and clarity.

2. Optical Construction:

   • The lens features a double Gauss type optical construction in front of the aperture, similar to the legendary Summilux-M 50mm f/1.4.
   • Behind the aperture, another highly refractive glass aspherical element reduces distortion and enhances overall sharpness.
   • A floating element maintains image quality throughout the focusing range, especially at close distances.

3. Maximum Aperture and Depth of Field:

   • With a bright f/2 maximum aperture, this lens excels in challenging lighting conditions.
   • The wide aperture also allows for precise control over depth of field, making it ideal for isolating subjects against beautifully blurred backgrounds.

4. Manual Focus and Close Focusing:

   • The lens offers manual focus, allowing photographers to fine-tune their compositions.
   • The minimum focusing distance is 2.3 feet (approximately 70 cm), and the maximum magnification ratio is 1:7.

5. Built-In Extendable Lens Hood:

   • To reduce lens flare and ghosting, the lens comes with a built-in extendable lens hood.
   • The front of the lens is threaded to accept 49mm screw-on filters.

6. Versatility:

   • Whether capturing intimate portraits, nature scenes, or landscapes, the APO-Summicron-M 75mm f/2 ASPH. delivers outstanding image quality.
   • It performs equally well on both analog and digital Leica rangefinder cameras.

7. Price and Availability:

   • The lens is priced at $4,895.00 (as of my last knowledge update).
   • Please note that availability may vary, so it's a good idea to check with authorized dealers or Leica directly.

In summary, the Leica APO-Summicron-M 75mm f/2 ASPH. is a masterpiece of optical engineering, combining precision, craftsmanship, and stunning image quality. Whether you're a portrait photographer or simply appreciate fine glass, this lens is a worthy addition to your kit.
