NiSi Close Up Lens Kit 77mm – Convert Telephoto Lenses into Macro with a Large Working Distance

The NiSi Close Up Lens Kit NC 77mm lets you use a telephoto lens as a macro lens while keeping a comfortable working distance. It works with zoom or prime lenses in the focal length range of 70–300mm (full-frame equivalent) and mounts on any lens that has a 77mm filter thread.

How the Close-Up Lens Works

This close-up lens reduces the minimal focal distance of your telephoto lens, allowing you to focus much closer to your subject. The magnification you achieve depends on the focal length of the lens: longer focal lengths provide higher magnification. For example, magnification will be close to 1:1 when you focus at 200mm.

Because the close-up lens changes the focusing range, you must be aware of the maximum and minimum distances at which you can focus. You will only be able to take a properly focused image within that range. The best working distance for this kit is 22–30 cm from the subject.

Optical Design and Image Quality

NiSi designed the close-up lens using double optical corrective glass elements with an apochromatic design. In addition, the elements feature a multi-nano coating. These optical choices aim to deliver advanced resolution and natural colour rendition. Furthermore, the apochromatic correction and coatings help minimise purple/green fringing both in sharp focus and within the bokeh.

Recommended Use

Use the NiSi Close Up Lens Kit primarily on telephoto or telephoto zoom lenses with focal lengths between 70 and 300mm. For the sharpest detail, NiSi recommends stopping down to apertures in the f/8–f/16 range when shooting with the close-up lens.

What’s Included and Compatibility

• NiSi Close Up Lens NC 77mm (main close-up lens element)
• Included adaptors for 67mm and 72mm filter threads

Key Features

• Close-up lens designed specifically for telephoto and telephoto zoom lenses
• Dual lens elements made from high-quality optical glass
• Apochromatic correction to reduce chromatic aberration

Practical Tips

1. Attach the close-up lens to any lens with a 77mm thread, or use the included 67mm/72mm adapters if needed.
2. Start at a longer focal length to increase magnification, then adjust your distance to keep your subject within the usable focusing range.
3. For the best detail, try apertures between f/8 and f/16, as recommended.

FAQ

Question: Which lenses are compatible with the NiSi Close Up Lens Kit 77mm?
Answer: The kit mounts on any lens that has a 77mm filter thread and is designed for use with lenses in the 70–300mm focal length range (full-frame equivalent).

Question: What magnification can I expect with this close-up lens?
Answer: Magnification varies with focal length. It increases with longer focal lengths and will be close to 1:1 when focused at 200mm.

Question: What working distance should I aim for when using the close-up lens?
Answer: The best working distance is 22–30 cm from the subject. Within the maximal and minimal focus distances for your setup, you will be able to capture properly focused images.

Question: What aperture should I use for the sharpest results?
Answer: NiSi recommends using the close-up lens on telephoto lenses stopped down to f/8–f/16 to achieve the sharpest details.

Question: What optical design features help image quality?
Answer: The close-up lens uses double optical corrective glass elements with an apochromatic design and multi-nano coatings to improve resolution, maintain natural colours, and reduce purple/green fringing in both focus and bokeh.
