The additional T-thread mount is pressed on, and could be easily removed if desired - see Picture #4. Leitz made two of these ultra-fast lenses. The other one is 90mm/f1.0, and I have one of these listed separately. These lenses are rare, and this would be an excellent opportunity to obtain both in excellent condition. After more than a century of fine optics production in Wetzlar Germany, Ernst Leitz established (1952) in Midland, Canada to manufacture Leica cameras and lenses. The Leitz Canada lenses are of extremely high quality, as would be expected from the Leica association. Even though I supply all the relevant lens information in my Listings, I get numerous emails asking whether this (or similar) fast lenses will fit on Nikon, Canon, Olympus, etc.

Full-frame cameras, or 4/3 Cameras, MFT cameras, Sony NEF cameras, etc. This lens will NOT mount directly to your consumer camera! You will need an adapter. The lens does NOT have a focus ring or aperture ring, unless specifically stated in the Listing that it does.

To achieve infinity focus the quoted Back Focal Distance (distance from the rear of the lens to the focal plane) must equal or exceed the flange distance for your camera. If you do not know that distance for your camera, google the Wikipedia article titled Flange Focal Distance.

You will also need to fabricate an adapter (using the thread on the lens barrel, or a press-on adapter) that will allow the lens to mount to your camera, and this adapter (in most cases) will add to the distance between the lens and the focal plane. With some lenses you may be able to have part of the rear lens projection insert part way into your camera, depending on the available clear inside diameter of your camera lens mount. For focus adjustment, the lens can be turned by its thread in the adapter that you would design and fabricate. If the lens cannot achieve infinity focus, You CAN still use the lens for close-up macro work, as then the image is in focus at a larger distance from the rear of the lens. The maximum object distance at which the lens will focus will depend on how close you can get the lens to your focal plane.

Back focal distance of lens (from rear of lens mount to image plane), as specified in the Listing. Camera flange distance (look up for your particular camera). S = F x (F d +f)/(f-d).

If F=65mm, d=6mm, f=18mm, then s = 417 mm (14.6). If F=90mm, d=7.5mm, f=18mm, then s =. Note only if d > f will the lens focus at infinity.
