Nine rings, starting at 37 mm

CAMKIX Nine step-up rings, 37 to 82 mm

Nine rings from 37 to 82 mm for 11 €, one more step than the Belmalia set at the same price, and the extra one is at the small end where kit lenses live.

CAMKIX Nine step-up rings, 37 to 82 mm

Nine rings from 37 to 82 mm for 11 €, one more step than the Belmalia set at the same price, and the extra one is at the small end where kit lenses live.

Mounts joined
NONE. Like the 11 € Belmalia and the 23 € K&F on this shelf, this is a filter-thread set: nine rings that let a larger filter sit on a smaller lens. The mount adapters here are the 95 € Canon and the 185 € Nikon, and they do a different job entirely
Contacts present
None, and none is possible at the front of a lens
Functions claimed
One, and the first bullet puts it as an economy rather than a feature: a new lens of a different diameter does not require a second set of filters. The second bullet states the mechanism — a larger filter onto a smaller thread
Optical elements
None
Tripod foot

Aperture ring

Build
Resistant anodised aluminium, in the fourth bullet, with the claim that these last much longer than plastic adapter rings. No stacking is mentioned anywhere — the 11 € Belmalia set advertises screwing its rings together, and this page leaves the possibility unstated

  • Nine steps from 37 mm, covering the small threads an eight-ring set misses
  • The same 11 € as the Belmalia set for one ring more
  • Steps up only, like every ring set that is not the 23 € K&F here

Best for: A bag mixing a small prime or kit zoom with larger lenses, where the 37 mm end is the thread that actually needs adapting.

On the listing

Five bullets, each opening with a tick. No need to buy further lens filters, since a new lens of a different diameter would otherwise mean a second set; a set of nine adapter rings letting a larger lens filter be mounted on a lens of smaller diameter; one step up to larger threads across a maximum of nine sizes from 37 mm to 82 mm, listed as 37-49, 49-52, 52-55, 55-58, 58-62, 62-67, 67-72, 72-77 and 77-82 mm; durable anodised aluminium in every ring, claimed to last much longer than plastic adapter rings; and a closing bullet offering other CamKix accessories for protecting, cleaning or improving photographs from a DSLR or a phone camera.

Thirty-seven millimetres, for the same eleven euros

One ring more than the Belmalia set, and it is the one at the bottom of the range. Kit zooms and small primes are where 37, 40.5 and 43 mm threads live, and those are the lenses a large filter is most often being borrowed for.

Nine steps, none of them down

Every ring here goes from a smaller lens thread to a larger filter. The 23 € K&F set on this shelf is the only one that also goes the other way, and that direction costs corners of the frame.

The maker compares its own metal to plastic

The fourth bullet does not merely name aluminium; it says what the alternative does. A plastic thread deforms under a heavy filter and seizes.

What the fifth bullet is for

Other CamKix products. Worth noticing on a page with five bullets, because it means the specification is really four.

More lens adapters

  • Canon EF-EOS R mount adapter between an EF lens and an RF body

    Canon EF and EF-S lenses onto RF bodies

    Ninety-five euros to put EF and EF-S lenses on an RF body, with ten cameras named, a sealed metal mount, and two caps and a pouch in the box.

    Mounts joined
    EF and EF-S to RF — a real mount adapter, unlike the three ring sets on this shelf, which join filter threads. The intro above explains why this direction works at all: an adapter can only add to the distance between mount face and sensor, and EF is the longer-flanged system, so the gap is filled by an empty tube rather than corrected by glass
    Contacts present
    Not itemised, and that is the gap on this page. The first bullet claims existing EF and EF-S lenses work with performance unchanged and in parts better, and the fourth says the body generates a crop for EF-S lenses — both of which require the body to know what is attached. The contacts are implied throughout and never listed
    Functions claimed
    Performance "unchanged and in parts better", in the first bullet. The intro above asks for functions one at a time — autofocus, aperture control, stabilisation communication, metadata — and this page names none of them individually, which is the pattern that tip warns about
    Optical elements
    None named, and none is needed here. EF sits further from the sensor than RF, so the adapter is a spacer; the corrective element the intro above describes belongs to adapters working the other way, against the flange distance
    Tripod foot
    Not mentioned. The intro above says a foot matters as soon as the lens outweighs the body, which on a mirrorless body with a long EF telephoto is most of the time
    Aperture ring
    Not on this version. The page describes one adapter and names no control ring and no filter slot
    Build
    A metal mount, dust- and splash-protected, in the third bullet. The fifth lists what comes with it: the adapter, an R-F-3 body cap, an RF rear lens cap, a pouch and a manual — two caps, because an adapter left on the body means the lens cap and the body cap no longer fit what they were bought for
    Amazon reference
    B07H5SL6W3 (same reference on 6 Amazon marketplaces)
    EAN
    4549292115703
    • Ten RF bodies named on the page, rather than a mount specification alone
    • A dust- and splash-protected metal mount, at 95 €
    • No function list: "performance unchanged and in parts better" stands in for autofocus and aperture claims

    Best for: A bag of EF glass moving onto an RF body, where the lenses are to keep working exactly as they did.

  • K&F Concept eighteen-piece filter ring set in its two rows of nine

    K&F CONCEPT Eighteen rings, nine up and nine down

    Eighteen rings for 23 €, nine up and nine down — the only set on this shelf that can fit a smaller filter to a larger lens, with the vignetting that implies.

    Mounts joined
    NONE, again: filter threads. The first bullet says the set matches a lens thread to the thread of any other accessory, which is the clearest statement of the job on this shelf. The 95 € Canon and the 185 € Nikon here are the mount adapters
    Contacts present
    None
    Functions claimed
    Fitting, in both directions — and the second direction is what distinguishes this set. The second bullet lists nine step-up rings, the third nine step-down, and the fourth says the ring screws easily onto the front of any lens
    Optical elements
    None
    Tripod foot
    Not applicable
    Aperture ring
    Not applicable
    Build
    Described in the first bullet as extremely robust and light, with NO MATERIAL NAMED — where the 11 € Belmalia and the 11 € CAMKIX both say anodised aluminium. The fifth bullet promises a perfect, secure fit with no wobble and no thread wear
    Amazon reference
    B00JL4HGAI (same reference on 6 Amazon marketplaces)
    EAN
    0700424378524
    • Eighteen rings, and the only step-down set on this shelf
    • The step-up half matches the nine sizes of the 11 € CAMKIX set exactly
    • No material named, where both 11 € sets specify anodised aluminium

    Best for: A bag where a filter is sometimes larger than the lens and sometimes smaller — a compact lens borrowing a big filter one day, a big lens borrowing a small one the next.

  • Nikon FTZ II adapter mounted between an F-mount lens and a Z-mount body

    Nikon FTZ II — F lenses onto Z bodies

    One hundred and eighty-five euros to put F-mount lenses on a Z body, with full autofocus and auto exposure claimed for "numerous" of them — and four bullets that name none.

    Mounts joined
    F to Z — the second true mount adapter on this shelf, beside the 95 € Canon. The intro above explains the direction: F sits far from the sensor because it was built around a mirror, Z sits close, so the adapter restores a distance rather than correcting an optical error
    Contacts present
    Not itemised, but necessarily there: the second bullet claims full autofocus and automatic exposure, and neither is possible through a passive tube. The page never says how many contacts or what else passes — stabilisation communication and metadata are not mentioned
    Functions claimed
    Two, and separately, which is more than any other adapter page here manages: FULL AUTOFOCUS and AUTOMATIC EXPOSURE, for "numerous" F lenses. The intro above warns that claims of this kind are graded rather than binary and that makers usually publish a compatibility list; the word "numerous" is doing the work of that list
    Optical elements
    None named, and none is required in this direction
    Tripod foot
    Not mentioned anywhere in four bullets. The intro above calls a foot important as soon as the lens outweighs the body, which describes most F-mount telephotos on a Z body
    Aperture ring
    Not mentioned. Older F lenses with no electronic aperture depend on how the adapter drives the mechanical lever, and the page says nothing about that at all
    Build
    Robust and protected against dust and splashes, in the fourth bullet, with good ergonomics claimed in the first. The third bullet — "a new level of sharpness" — is a claim about image quality on a device this page never says contains an optical element
    Amazon reference
    B09KKTQSQ9 (same reference on 6 Amazon marketplaces)
    EAN
    4960759909121
    • Autofocus and automatic exposure claimed as two separate functions, not as one word
    • Dust and splash protection on a 185 € adapter, matching the 95 € Canon here
    • Four bullets, and not one names a lens or a body

    Best for: F-mount glass moving onto a Z body, for a buyer who will check their own lenses against the maker’s published list elsewhere.

Elsewhere in the camera bag

  • LENS-AID universal lens cap showing its centre pinch and ribbed outer rim

    LENS-AID 55 mm, centre pinch AND outer grip, 17 sizes

    Six euros for a cap that can be squeezed in the middle or gripped at the edge, from a range of seventeen diameters — and it fits a filter’s thread as well as a lens.

    Cap type
    A front cap sold as a replacement, in the fourth bullet, for a lost original or as a spare kept permanently in the bag. That is the honest framing of what this shelf sells: nobody buys their first cap
    Thread or mount fit
    55 mm here, from a published range of SEVENTEEN diameters — 37, 39, 40, 43, 46, 49, 52, 55, 58, 62, 67, 72, 77, 82, 86, 95 and 105 mm, in the fifth bullet. The range includes the odd sizes that are hardest to find: 39, 40 and 43 mm belong to old primes and adapted lenses, and 86, 95 and 105 to large telephotos
    Pinch mechanism
    BOTH, and it is the only cap on this shelf that offers the pair: the third bullet says it can be squeezed on the inside OR the outside, and stays comfortable to use with a hood or a filter fitted. Centre for a hood, rim for cold fingers
    Tether provision
    None
    Material
    Not named
    Pack contents
    Not stated. What the second bullet adds instead is unusual: compatibility with Canon, Sony, Nikon, Fujifilm, Tamron and Sigma lenses AND with round filters of matching diameter — a cap that screws onto a filter rather than only onto a lens

    4260668674074
    • Centre pinch and outer grip, the only cap here with both
    • Seventeen diameters published, including the hard-to-find 39, 40 and 43 mm
    • No tether, where the 4 € JJC has a keeper cord

    Best for: An odd thread size a maker no longer supplies, or a bag where one spare cap should fit a filter as well as a lens.

  • CamKix cleaning kit with two spray bottles and two microfibre cloths

    CAMKIX Two sprays, two microfibre cloths — no blower

    Seven euros for two sprays and two microfibre cloths — a lens and screen kit with no blower, which is the first tool the job needs.

    Kit contents
    FOUR ITEMS: two cleaning sprays and two microfibre cloths, in the title and the first bullet. It is the smallest kit on this shelf — the 17 € K&F has four kinds of tool and the 30 € UES has seven — and what it omits is the part that comes first
    Blower valve and nozzle
    NONE. There is no blower in this kit, and that is the significant absence: the hub above and every cleaning procedure start by blowing loose grit OFF the glass, because wiping it instead drags it across the coating. A cloth used before a blower is how lenses get scratched
    Cloth type and count
    TWO microfibre cloths, in the title and the first bullet, with no size, weave or washability published. Two is the right number — one damp, one dry — and nothing else about them is stated
    Fluid composition stated
    NOT STATED. The second bullet claims the spray removes dust, streaks and fingerprints and that dust and streaks stay away longer afterwards, and never says what is in it. Alcohol content is the question — it matters for coated optics and for OLED screens — and neither is addressed. The 30 € UES on this shelf publishes an ALCOHOL-FREE pure-water cleaner
    Swab sizing
    NONE. No sensor swabs, so this kit cleans the outside of a camera and never the sensor
    Packaging
    Not described. The 30 € UES supplies a waterproof hard case and the 17 € K&F a bag-friendly set; this page says nothing
    Amazon reference
    B013UBXVI8 (same reference on 6 Amazon marketplaces)
    EAN
    0711099323870
    • Two sprays and two cloths, so one cloth stays dry
    • Eleven lens makers named as safe, and phone and tablet screens included
    • No blower, which is the tool a cleaning routine starts with

    Best for: A bag that already contains a blower, where a spray and a spare cloth are what is missing.

  • K&F Concept cleaning kit with its valved air blower and microfibre cloth

    K&F CONCEPT 4-in-1, blower with a valve, microfibre cloth

    Seventeen euros for a four-piece kit whose blower has a valve — so it refills with clean air instead of sucking back the dust it just removed.

    Kit contents
    FOUR items, described in the first bullet as carefully selected tools and materials, safe and effective for a camera and other sensitive optics. Only two are named individually — the blower and the microfibre cloth — which leaves half the kit unspecified on a page of five bullets, two of which are the same sentence twice
    Blower valve and nozzle
    A BLOWER WITH A VALVE SYSTEM, in the second bullet, credited with optimal blowing action and contact-free removal of deep-seated dirt by simple pumping. The valve is the specification worth having: a plain bulb draws its next breath back through the same nozzle, sucking in the dust it just blew off, while a valved bulb takes clean air in through a separate inlet and sends only that at the glass
    Cloth type and count
    A microfibre cloth, in the second bullet, described as lint-free through a high-quality fibre structure, cleaning dirt thoroughly without scratches, and reusable. The count is not published — one is implied
    Fluid composition stated
    NOT STATED, and no fluid is clearly named among the four items. The 7 € CAMKIX supplies two sprays and says nothing about them; the 30 € UES publishes an alcohol-free pure-water formula
    Swab sizing
    NONE. The third bullet names cameras, lenses, phones, camcorders and glass surfaces — the outside of things. The sensor needs swabs, and only the 30 € UES on this shelf has them
    Packaging
    No case supplied. The fourth bullet says it stows easily in a camera backpack or bag and is easy to operate, adding that it does not need to do more than that — and the fifth bullet repeats the same sentence word for word
    Amazon reference
    B00JL4IWXI (same reference on 6 Amazon marketplaces)
    EAN
    0700424379170
    • A valved blower, which sends clean air rather than recycled dust
    • A lint-free reusable microfibre cloth described by what it avoids
    • Two of its five bullets are identical, and two of its four items are unnamed

    Best for: The everyday routine — air first, then a dry cloth — on lenses, screens and camera bodies.
