FOREWORD

The Micro-Nikkor 105mm f/4 is a special telephoto lens designed for close-up photography at high reproduction ratios. It features the same optical construction as the much-acclaimed Bellows-Nikkor 105mm f/4, but with a special focusing helicoid that enables operation from infinity (°°) to a reproduction ratio of 1 : 2 (half life-size) without the need for any adapters. The lens offers "automatic maximum aperture indexing" (Al) with suitably equipped cameras, via the meter cou- pling ridge provided. The ridge and the auto diaphragm function to- gether to permit full aperture exposure measurement; the lens is also fitted with a meter coupling shoe to permit the same operation with Nikon cameras which lack the Al facility. In terms of optical perform- ance, the Micro-Nikkor's excellent flatness of field is a stand-out feature, enabling virtually distortion-free images at all reproduction ratios. The application of Nikon Integrated Coating (NIC) further en- hances performance by increasing image contrast, while reducing flare and ghost, for outstanding color reproduction.

When the Micro-Nikkor 1 05mm is used with the special Auto Extension Ring PN-11 or PN-1, focusing is further extended from 1 : 2 to 1 : 1 for full life-size reproduction.

To get the best results from your Micro-Nikkor 105mm f/4, read this instruction manual carefully. Keep the manual handy for reference until you have thoroughly familiarized yourself with the lens and its operation. A few minutes of preparation will help you avoid costly mistakes.

Micro-Nikkor 105mm f/4 specifications

The Nikon Micro-Nikkor 105mm f/4 is a renowned macro lens that has captured the interest of photographers, particularly those specializing in close-up and nature photography. With its extraordinary delivery of sharpness and precision, this lens has established itself as a favorite among both amateurs and professionals.

One of the main features of the Micro-Nikkor 105mm f/4 is its impressive 1:1 reproduction ratio. This capability allows photographers to capture life-sized images of small subjects, making it ideal for macro photography. The lens provides a working distance of approximately 6.3 inches, which is advantageous for keeping a safe distance from delicate subjects, such as insects and flowers, ensuring that they remain undisturbed.

The lens construction includes 9 elements in 8 groups, which work together to minimize chromatic aberrations and distortions. This optical design, along with the Nikon multicoating technology, enhances light transmission and reduces flare and ghosting, resulting in clearer and more vibrant images. The lens exhibits exceptional sharpness, even at its maximum aperture of f/4, while maintaining good image quality throughout its aperture range.

Another significant feature of the Micro-Nikkor 105mm f/4 is its focus mechanism. The lens utilizes a manual focus system with a smooth focus ring, making it easier for photographers to achieve precise control when working with close-up subjects. Furthermore, it has a relatively compact and lightweight design, making it portable for outdoor shooting.

The Micro-Nikkor 105mm f/4 is equipped with the well-regarded Nikon close-up capability, allowing users to easily shoot in challenging macro environments. It also has a rubber seal that offers some degree of protection against dust and moisture, although it is not entirely weather-sealed.

Additionally, this lens is compatible with Nikon's tele converters, which can extend its focal length for even greater close-up capabilities while retaining image quality.

In conclusion, the Nikon Micro-Nikkor 105mm f/4 stands out with its high-quality optics, versatile macro capabilities, and user-friendly design. It is a valuable tool for photographers looking to explore the intimate details of the small world around them.
