Pairing the classic normal focal length with an optically refined design, the silver anodized APO-Summicron-M 50mm f/2 ASPH. Lens from Leica is a fast standard prime characterized by its apochromatic designation. Using anomalous partial dispersion and high refractive index glasses in its design, this lens is capable of focusing red, green, and blue wavelengths at the same plane in order to virtually eliminate chromatic aberrations. One aspherical element is also featured in the design, to reduce spherical aberrations, and a floating element maintains clarity and sharpness throughout the focusing range from 2.3' to infinity. This compact 50mm lens is also distinguished by its compact form factor, making it ideal for use as an everyday lens. Like all M-mount lenses, this 50mm f/2 features a manual focus design, and a convenient focusing tab for more refined control during use.

Apochromatic design employs three elements made from anomalous partial color dispersion glass, as well as two high refractive index elements, in order to suppress chromatic aberrations throughout the aperture range for increased color accuracy and clarity.

One aspherical element reduces spherical aberrations for improved sharpness from edge to edge.

A floating element is used to maintain clarity and sharpness throughout the focusing range, from 2.3' to infinity.

In addition to the apochromatic designation, this lens also pairs a Gaussian type optical construction in front of the aperture along with a design resembling the Summilux-M 50mm f/1.4 behind the aperture, in order to significantly reduce distortion while also increasing overall sharpness and consistent illumination.

Bright f/2 maximum aperture benefits working in difficult lighting conditions and also affords greater control over depth of field.

Compact overall design is ideal for use in everyday shooting situations.

Manual focus design provides a minimum focusing distance of 2.3' with a maximum magnification ratio of 1:11.3.

Built-in extendable lens hood shades and protects the front element to reduce lens flare and ghosting. Additionally, the front of the lens is threaded to accept 39mm screw-in filters.

Q: 1. Is the Leica 90 mm F 2 axe in Germany?

A: The Leica APO-Summicron-M 90mm f/2 ASPH. Lens is made in Germany as per our records. Please note that this is subject to change at any time.

Q: 2. Does this have the same internal focus scheme as the older Leica Summicron-R 90mm APO SLR lens? (does not telescope when focussed)

A: It apparently does not. The barrel does extend while focusing.

Q: 3. This is a brand new one never used with full warranty?

A: All items in our inventory are new unless clearly stated otherwise on the item's page, or if you are searching on the Used section of our website.

Q: 4. When can one expect this lens to arrive in stock??

A: With Leica it is very difficult to predict when they will stock this lens. On a back-ordered Leica lens such as this one it usually takes at least 6-8 weeks to come into stock.

Q: 5. Does it come with a lens hood, or is it built?

A: Leica APO-Summicron-M 50mm f/2 ASPH. Lens (Black) has a built in lens hood.

Q: 6. is this lens weather/dust sealed?

A: No, the Leica APO-Summicron-M 50mm f/2 ASPH. Lens offers no weather sealing.

Q: 7. i can't tell if this lens has auto focus?

A: If you have to ask the question, you should read more about the Leica M system. It's far more remarkable than you possibly can imagine. It's ... magic!

Q: 8. i can use this on a fujifilm xt4 with a k&f L/M to FX adapter ?? ty

A: We do not sell K&M adapters but the following adapters will allow you to use this lens on an XT4; https://bhpho.to/3ftsn4P

Q: 9. Why is this lens more expensive than the Summilux F1.4?

A: An APO lens (apochromatic), has better correction of chromatic and spherical aberration than other non-APO ones. And it shows, shooting wide open you will see that purple fringing is almost non-existent. It also has better wide-open sharpness.There's an article comparing different 50mm lenses by lensrentals, which is a recommended read.

Q: 10. Does this lense have 6 bit interface?

A: Yes. This has 6-bit coding.
