NiSi ONE achromatic doublet, 77 mm, about 1:1 at 200 mm

One corrected doublet rather than four single elements — apochromatic, coated, with two step-up rings, quoted at about 1:1 at 200 mm, for 139 €.

NiSi 77 mm close-up lens with its two step-up rings and caps

NiSi ONE achromatic doublet, 77 mm, about 1:1 at 200 mm

One corrected doublet rather than four single elements — apochromatic, coated, with two step-up rings, quoted at about 1:1 at 200 mm, for 139 €.

Dioptre strength
NOT GIVEN IN DIOPTRES — and that is deliberate. The second bullet quotes a reproduction ratio instead: about 1:1 when used at 200 mm, on a zoom or prime in the 70 to 300 mm range. A ratio says what fills the frame; a dioptre only says where the glass focuses, and the intro above explains that the same dioptre behaves differently on every focal length
Filter thread
77 mm, with TWO STEP-UP RINGS in the box — 67-77 and 72-77 mm, in the fifth bullet. That is the buying advice above followed by the maker: buy for the largest thread and step down, and two of the rings that the 11 € Belmalia set on this shelf sells eight of arrive with the lens
Element count
TWO, cemented as a DOUBLET, with an apochromatic design, in the first bullet. It is the only corrected close-up lens on this shelf, and the intro above names that as the line that separates the shelf: a single element is a magnifying glass and shows it at the edges, while a doublet corrects colour fringing and costs several times as much for a visible reason
Whether the set is achromatic
YES, and it is the only one on this shelf. The first bullet gives two doubled optical glasses in an apochromatic design; the third gives the consequence, a special design against colour shift said to reduce purple and green borders considerably. The intro above explains the price of that: an achromatic doublet corrects colour fringing and costs several times as much for a visible reason — here 139 € against 20 to 53 € for uncorrected sets. It is also one lens rather than four
Coating described
A NiSi multilayer nano coating, in the first and fourth bullets, credited with improved resolution, natural colour, optimal clarity, easy cleaning and water- and grease-repellency. Named twice, which on this shelf only the 53 € K&F otherwise manages
What a multi-piece set contains
One 77 mm close-up lens, one 67-77 mm adapter ring, one 72-77 mm adapter ring, two lens caps and a pouch, in the fifth bullet. Two caps because a lens of this kind stays on the front of a lens that still needs covering

  • A two-element apochromatic doublet — the only corrected close-up lens on this shelf
  • Strength quoted as a reproduction ratio, about 1:1 at 200 mm, not as a dioptre
  • One lens, where 20 € to 53 € buys four strengths on this shelf

Best for: A 70-300 mm telephoto used for close work where purple and green fringing at the edges is the problem to be solved.

On the listing

Five bullets. Made from two doubled optical glasses with an apochromatic design and a NiSi multi-nano coating, for improved resolution and natural colour; recommended with zoom or prime lenses in the 70 to 300 mm range, with a reproduction ratio of about 1:1 when shooting at 200 mm; a special design against colour shift, said to reduce purple and green borders considerably; a NiSi multilayer nano coating for optimal clarity and easy cleaning, repelling water and grease; and a kit containing one 77 mm close-up lens, one 67-77 mm adapter ring, one 72-77 mm adapter ring, two lens caps and a pouch.

Two glasses, cemented

The line the intro above draws across this shelf. Three sets here are single elements and say nothing about correction. This one is a pair, designed so that red, green and blue land in the same place.

One to one, at two hundred millimetres

A ratio instead of a dioptre: the subject at life size, comparable with a macro lens rather than with another filter.

Two step-up rings, in the box

Sixty-seven to 77 and 72 to 77. The maker follows its own shelf’s advice — buy for the biggest thread, step down to the rest — and supplies the rings to do it.

Seventy to three hundred millimetres, and not below

A telephoto accessory. On a standard zoom at 35 mm it is the wrong tool, which is the price of a design aimed at one job.

A hundred and thirty-nine euros for one strength

The 20 € Walimex pro gives four dioptres and no coating claim. This gives one corrected pair, a coating named twice, and the reason the difference exists.
