Complementing the DX macro lens, the Nikon AF-S DX Micro-NIKKOR 40mm f/2.8G Lens with Accessory Kit from B&H bundles the close-up optic with 52mm UV and circular polarizer filters, as well as a bottle of lens cleaning fluid.
Excelling at close distances, the AF-S DX Micro NIKKOR 40mm f/2.8G from Nikon is a 60mm-equivalent macro prime offering a 1:1 life-size maximum magnification along with a 6.4" minimum focusing distance. Benefitting both close-up shooting as well as working at greater distances, the optical design uses a Close Range Correction system that maintains consistent image quality and sharpness throughout the focusing range. Individual elements also feature a Super Integrated Coating, which suppresses flare and ghosting for greater contrast and color fidelity and harsh lighting conditions. Additionally, complementing the imaging capabilities, a Silent Wave Motor affords fast and precise autofocus performance, along with full-time manual focus override, to benefit both stills and video applications.
This Sunpak 52mm Filter Kit includes a 52mm UV Filter and a 52mm Circular Polarizer Filter. Each filter in this kit fits a lens with 52mm front filter threads and can provide one of two enhancements to your imagery. Additionally, these filters are constructed from optical glass within an aluminum-alloy frame, which protect the front element of a lens from scratches, bumps, or impacts. A filter case that can accommodate both filters is included for storage and transport.
The Sunpak 52mm UV Filter is a general use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter.
This UV filter is also useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.
The Sunpak 52mm Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.
The Sunpak 52mm UV Filter and Sunpak 52mm Circular Polarizer Filter are both non-coated and are constructed from optical glass for clarity and color fidelity. Additionally, they each feature an aluminum-alloy filter ring for durability while remaining lightweight.

Keep your optical surfaces clean with the Sensei OC-CK Optics Care and Cleaning Kit. This kit contains a pack of lens tissues, a lens cleaning pen, bulb air blower, paint brush, lipstick brush, lens cleaning fluid, microfiber cleaning cloth, and see-through mesh travel case to put everything in. This kit can be used to clean a variety of different optics and glass. You can use the air bulb blower and any of the three supplied brushes to initially remove dust from the surface. Sensei recommends applying a small amount of the alcohol- and ammonia-free cleaning fluid directly to the lens tissue. Then, gently rub in small circular motions to remove stubborn smudges or fingerprints from the glass. For those more stubborn blemishes or smudges, the lens pen is very effective.
