o NiSi close-up lens II 77mm allows you to increase the multiplication factor of your lens. Thanks to this lens, you can turn your telephoto lens into a macro lens with magnification even up to 1: 1 (or more!). We recommend using the NC Macro NiSi close-up lens with lenses with focal lengths between 70 and 200mm. So any lens that presents (even partially) these focal lengths is fine. The close-up lens is perfect with 70-200 f / 2.8 or f / 4 lenses and also with 70-300, 18-105mm, 24-105, 100-400 and so on. The best performances are between 70 and 200mm, but you can also experiment with other focal lengths and you will be surprised by the sharpness of the NiSi optical glass. The main features:
Optical glass for NiSi precision applications. As always, the best optical glass on the market.
Double apochromatic optical element
Multi-Nano Coating NiSi (NC) treatment, for better sharpness and easy cleaning from water and grease (such as fingerprints)
Magnification very close to 1: 1 when shooting at 200mm
Design that significantly reduces the purple/green fringing
Diopters +3-4 (between 3 and 4 diopters)
The close-up lens screws directly to 77mm thread lenses, but adapter rings are included in the kit for use with 72mm and 67mm threads. You can use a third party adapter ring to use the Close-up NiSi lens with lenses with any thread, the important thing is to have focal lengths between 70 and 300mm.
Autofocus remains active in most lenses, in the range of use (e.g. between about 20cm and 30cm with most lenses)
Includes two (front and rear) lens caps to protect your lens when not in use
