Nikkor P.C 8.5cm F2 LTM

The Nikkor-P.C 8.5cm f/2 was a significant lens introduced by Nikon. The medium telephoto lens was introduced in 1953 as Nikon’s first attempt at this focal length. The lens is based on the popular Zeiss Sonnar design and It was one of their best selling lens. The Nikkor 8.5cm f/2 was competing against likes of Leica and Canon with similar focal length offerings. The size advantage and smooth rendering makes the Nikkor stands out from the rest of the competition.

Nikkor 5cm f/1.1 | Nikon 50mm F1.1 LTM Lens

Nikkor 50mm f1.1 lens was the world’s second fastest production lens since the release of Zunow 50mm f1.1. Zunow began the development for ultra fast lenses in 1953 and Nikon joined the competition a few years later in 1956.

The Nikkor 50mm F1.1 is a rare and collectible lens. It is an impressive lens that offers ultra shallow depth of field at f1.1 in reasonable size and weight.

Production Versions

1. Internal Nikon Mount (1500 units)
2. External Nikon Mount (1800 units)
3. Leica Screw Mount / LTM (200 units)

The Lens also can be modified to Leica M Mount through a professional technician, which allows it to be used on Leica M Rangefinders without the need of adapters.

Build Quality

The Nikkor 50mm F1.1 is a solidly constructed lens with different barrel design but same optics throughout its version variants. Normally, the barrel design is consisting of a black paint lens body with a chrome barrel ring on top. The lens reviewed here has been modified to Leica M mount, which displays an extra section of mount finished in matte black.

The size and weight of the lens is similar to the Voigtlander 50mm F1.1 or the Leica 50mm F1.2 Noctilux, which is not too heavy and well balanced on Leica Rangefinders. The lens is relatively compact considering it is an ultra fast lens with a maximum aperture of F1.1.

Common Issues

A) Separated Lens Element

B) Damaged Diaphragm Blades

Both issues can be fixed by a skilled technician.

Image Quality

The Nikkor 50mm F1.1 produces decent sharpness when shot wide open and offers a very shallow depth of field. At its maximum aperture of F1.1, It is sharp in the center but soft around the corners. However, the sharpness increases gradually when stepping down until it reaches peak sharpness at F8. The rendering of the lens is very similar to its little brother the Nikkor-SC 50mm F1.4  with classical Nikon rendering and signature vintage soft glow when shot wide open.

Nikon applied their lastest optical technology at the time by applying guass elements to three convex lenses. This results more glass to weaken each lens element in order to reduce the curvature of field and correct spherical aberration As a result of its symmetric optical design, the lens achieves low distortion, minimal lateral chromatic aberration and high resolving power.

Nikkor 50mm F1.1 vs Canon 50mm F0.95

The Canon 50mm f0.95 is about twice the size of Nikkor 50mm f1.1 and the Nikkor 50mm f1.1 is about half of the weight of the Canon 50mm f0.95 lens.

The Canon 50mm f0.95 was produced in greater numbers hence is much less expensive. The Nikon lens design is 9 elements in 7 groups and the Canon design is 7 elements in 5 groups. Therefore, the Canon used a newer optical design in their lenses that requires less elements allowing extra light to be transmitted.

Conclusion

The Nikkor 50mm F1.1 lens was designed more than 50 years ago and still remains a legend in the rangefinder world. As the second ultra fast lens ever produced in history and it continues to live up to modern imaging standards.

Nikkor-S.C. 5cm f/1.4 | Nikon 50mm F1.4 LTM Lens Review

See comparison with the Legendary Lens

Nikkor 5cm f/1.1 | Nikon 50mm F1.1 LTM

If you are looking for a vintage lens with classic character and don’t mind the sharpness then look no further. The Nikkor-SC 5cm f1.4 or commonly known as the Nikon 50mm F1.4 LTM lens is the perfect choice. It is compact, solid, unique and affordable at the same time.

Build Quality

The First Impression of the Nikkor 50mm f1.4 lens is that it feels incredibly solid and dense. The lens is small and compact but it is well constructed as the entire body is made of chrome brass. It is extremely high quality lens and feels balanced when mounting on Leica M rangefinders. Overall, It offers a compact and solid package.

Image Quality

The Nikkor 50mm f1.4 provides great image quality with full of character. When shot wide open, the image sharpness isn’t clinically sharp like some Leica lenses but it produces a soft glow common only to certain vintage lenses. However, it also lacks contrast and clarify like on most modern lenses.

At its minimum aperture of f1.4, the point of focus is relatively sharp and the out of focus area provides the soft vintage glow. The sharpness increases dramatically when stepping down the aperture with its peak image performance between f5.6 - f8. The lens does suffer the common issues with older lenses such as chromatic aberration and vignetting. The image quality isn’t perfect but it is unique with classic characteristics, which makes it perfect for monochrome renderings.

Practical Use

The Nikkor 50mm f1.4 LTM is a small, compact, lightweight and solidly built lens. It feels very balanced on Leica rangefinders and easy to carry around to everywhere. This lens is in Leica thread mount (LTM), therefore will require a LTM-to-M adapter to work properly on Leica M bodies.

The aperture ring provides a soft click when selecting the aperture unlike distinctive aperture clicks on most Leica lenses. The focusing ring does have a lock mechanism for infinity but once unlocked by pressing down the little lock button, the focusing ring feels very smooth with a long focus throw when turning.

Overall, the Nikkor 50mm f1.4 LTM Lens is intuitive to use and simple to operate once familiar with practicality of the lens. It is a vintage fast lens from the 1950s with classical rendering and yet it works perfectly on modern Leica Rangefinders.
