A mount, not a filter thread — and ten bodies named

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.

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

  • 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.

On the listing

Five bullets. Existing EF and EF-S lenses used on a Canon EF-EOS R camera with performance unchanged and in parts better; an adapter that fits any RF-mount body, naming the EOS R, RP, R6, R5, R3, R6 Mark II, R50, R8, R7 and R10; a metal mount protected against dust and splashes; EF-S lenses also attachable, with the camera then generating a cropped image area; and a contents list of the mount adapter, an R-F-3 body cap, an RF rear lens cap, a pouch and a user manual.

A mount, where three pages on this shelf sell a thread

The word “adapter” covers two objects here. Eleven to 23 € buys a hollow ring that fits a filter to the front of a lens. Ninety-five euros buys the piece that lets a lens from one system sit on a body from another.

Ten bodies, named

The second bullet lists them instead of stating the mount and leaving the reader to infer. That is the compatibility list the intro above asks for, and the 185 € Nikon on this shelf does not provide one.

Why nothing optical is inside

EF sits further from the sensor than RF, so the adapter restores a distance rather than correcting one. Glass would only be needed adapting the other way.

Two caps, and the reason there are two

An adapter that lives on the body leaves the original body cap and rear lens cap fitting nothing. The fifth bullet supplies both replacements.

More lens adapters

  • 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

    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

    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

    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.

  • Belmalia set of eight black anodised step-up rings laid out in order of size

    Belmalia Eight step-up rings, 49 to 82 mm

    Eight anodised rings from 49 to 82 mm for 11 €, each stepping up one size, and screwable into one another to reach the gaps between.

    Mounts joined
    NONE — and this is the distinction the word "adapter" hides on this shelf. These are filter-thread rings: they join a larger filter to a smaller lens thread, in eight steps from 49 to 82 mm. No camera mount is involved at any point. The 95 € Canon and the 185 € Nikon on this shelf are the mount adapters; three of the five pages here, this one included, are rings
    Contacts present
    None, and none is possible: a filter ring sits at the front of the lens, where there is nothing to communicate with
    Functions claimed
    One: fitting. The first bullet says larger filters or converters can be used on lenses of smaller diameter, and that is the whole claim. Nothing is passed, nothing is powered, nothing is lost
    Optical elements
    None. The rings are hollow metal, which is why they cost 11 € and change nothing about the image — the intro above reserves corrective elements for adapters working against the flange distance
    Tripod foot
    Not applicable
    Aperture ring
    Not applicable
    Build
    Anodised aluminium, in the third bullet, described as stable, dimensionally true and light. The fourth bullet claims precisely cut threads that neither tilt nor jam, and the second says the rings screw into one another to reach intermediate sizes — 49 to 58 through two rings, for instance
    Amazon reference
    B00OE7B0UE (same reference on 6 Amazon marketplaces)
    EAN
    4054438653150
    • Eight consecutive steps from 49 to 82 mm, with no gap left in the sequence
    • Anodised aluminium rather than plastic, at 11 € for the set
    • Steps UP only: a smaller filter cannot be put on a larger lens with these

    Best for: One set of large filters shared across several lenses, where every thread in the bag is 49 mm or more.

  • 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)

    • A valved blower, which sends clean air rather than recycled dust
    • A lint-free reusable microfibre cloth described by what it avoids

  • UES DKL24 kit open in its hard case showing swabs, cleaner, blower and cloths

    UES DKL24, ten 24 mm swabs, alcohol-free, hard case

    Thirty euros for the only sensor kit on this shelf — ten 24 mm swabs, vacuum-packed, with an alcohol-free cleaner and a hard case.

    Kit contents
    SEVEN kinds of tool, itemised in the fifth bullet: ten 24 mm swabs, 30 ml of cleaner, one blower, one lens pen, fifty sheets of optical tissue, five microfibre lens cloths and one chamois display cloth. It is the only itemised list on this shelf — the 17 € K&F claims four items and names two
    Blower valve and nozzle
    A blower described in the third bullet as compact with an extremely strong airflow, for safe contact-free removal of loose dust — and the reason is stated properly: it stops grains of dust scratching the sensor or the lens during the wipe that follows. No valve is mentioned, where the 17 € K&F names one
    Cloth type and count
    The fullest provision here, and counted: FIVE ultra-soft microfibre cloths for lenses, FIFTY sheets of lint-free optical paper, and ONE chamois cloth specifically for camera displays. Separating the screen cloth from the lens cloths is the detail — a cloth that has touched a greasy screen should never go near a coated front element
    Fluid composition stated
    PUBLISHED: an ALCOHOL-FREE PURE-WATER cleaner, 30 ml, in the second bullet, stated to lift stubborn marks streak-free WITHOUT attacking the sensitive sensor coating. It is the only fluid composition on this shelf, and on a sensor it is the specification that matters most
    Swab sizing
    TEN SWABS AT 24 mm, individually VACUUM-PACKED, sized to fit a full-frame sensor exactly, in the second bullet. Both halves matter: 24 mm is the short dimension of a 36 by 24 mm sensor, so one pass covers it; and vacuum packing means each swab arrives dust-free, which is the whole point of a single-use swab
    Packaging
    A robust WATERPROOF HARD CASE, in the fifth bullet, named as ideal for travel. It is the only case on this shelf, and it is what keeps fifty sheets of tissue and five cloths from becoming dust carriers in a bag
