K&F CONCEPT Four dioptres, +1 +2 +4 +10, 77 mm, nano coating

Fifty-three euros for +1 to +10 in 77 mm with a nano coating, an EVA case — and the only page here that names the aperture and the focal length to use.

K&F Concept close-up filter set in its four-compartment EVA case

K&F CONCEPT Four dioptres, +1 +2 +4 +10, 77 mm, nano coating

Fifty-three euros for +1 to +10 in 77 mm with a nano coating, an EVA case — and the only page here that names the aperture and the focal length to use.

Dioptre strength
Four: +1, +2, +4 and +10, in the first bullet, which also says several filters can be combined to increase magnification and that the higher the dioptre the shorter the close range. That last clause is the working-distance answer the other pages leave out
Filter thread
77 mm, in the title — the size the buying advice above recommends buying for, because a step ring brings a large filter down to a small lens and costs 11 € on this same shelf
Element count
Not published. The second bullet describes highly transparent optical glass with a coating; it claims no doublet and no apochromatic correction, which is what separates it from the 139 € NiSi. The first bullet is candid about the trade: this is macro at a fraction of the cost of a macro lens
Whether the set is achromatic
NO — and this page is the one that says so between the lines. Its first bullet calls the set macro at a fraction of the cost of a macro lens, and its answer to edge softness is advice rather than glass: stop down to F5.6–F11, stay at 35 mm or longer. The coating is multi-layer and described at length; the CORRECTION is never claimed, and a coating suppresses reflections rather than colour fringing. The 139 € NiSi here is where the doublet begins
Coating described
FULLY, and it is the best coating description on this shelf: a multi-layer AR nano coating on highly transparent optical glass, credited with markedly increased transmission, stray-light-free imaging, effective suppression of flare and ghosting, and an image with no darkening and no colour cast
What a multi-piece set contains
A high-density EVA case with four separate compartments, described as shock-, break- and pressure-resistant, plus THREE dust-free vacuum-packed cleaning cloths, in the fourth bullet. The fifth adds a precision-machined metal filter ring and scratch-resistant glass
Amazon reference
B0H86QPKBH (same reference on 6 Amazon marketplaces)
EAN
6942610305493
  • The only page here that names an aperture range: F5.6 to F11 for best sharpness
  • The only one that names a focal length floor: 35 mm and up, to avoid vignetting
  • No element count and no achromatic claim, at 53 €

Best for: A 77 mm lens used carefully — stopped down, at 35 mm or longer — where the coating and the advice are worth more than the extra 33 €.

On the listing

Five bullets. A macro filter set with multi-level magnification at +1, +2, +4 and +10, the higher dioptre giving the shorter close range, filters combinable to increase magnification, with a small aperture of F5.6 to F11 recommended for optimal sharpness, for detailed shots of insects, stamens, jewellery and watch textures at a fraction of the cost of a macro lens; a nano coating of highly transparent optical glass with a multi-layer AR nano treatment for markedly increased transmission, stray-light-free imaging and effective suppression of flare and ghosting, giving a bright clear image without darkening or colour cast; universal lens compatibility with common DSLR and mirrorless cameras and standard, zoom and prime lenses, ready to use through filter-thread adaptation, with vignetting avoided from 35 mm upward and a fixed focal length recommended on zooms; a high-density EVA case with four separate compartments, shock-, break- and pressure-resistant, including three dust-free vacuum-packed cleaning cloths; and a robust, outdoor-ready precision-machined metal filter ring with scratch-resistant glass.

F5.6 to F11, printed on the page

The one number that decides whether a cheap dioptre looks good. Stopping down deepens a depth of field the filter has made paper-thin and hides the edge softness single glass produces. Three other pages on this shelf say nothing about it.

Thirty-five millimetres and longer

Below that, the frame sees the filter ring. It is the same geometry the step-up rings on this shelf inherit, and this is the page that states the floor.

A coating described, layer by claim

Transmission up, flare and ghosting down, no darkening, no colour cast. Twenty-euro sets on this shelf publish nothing about their coatings at all.

What fifty-three euros still does not buy

An element count, or a doublet. The first bullet is honest about the position: this is macro at a fraction of a macro lens, and the 139 € NiSi is where correction begins.

Four compartments, and three cloths

An EVA case that holds each filter apart from the next. Glass stored loose gets scratched by the glass beside it.
