The only magnification figure on the page is the camera’s digital zoom

NEEWER For DJI Osmo Pocket 3 and 4, magnetic

Sixty-four euros for a magnetic converter that clips to an Osmo Pocket 3 or 4 — and whose only published magnification is the 2× digital zoom already in the camera.

NEEWER teleconverter clipped magnetically to the front of a DJI Osmo Pocket

NEEWER For DJI Osmo Pocket 3 and 4, magnetic

Sixty-four euros for a magnetic converter that clips to an Osmo Pocket 3 or 4 — and whose only published magnification is the 2× digital zoom already in the camera.

Magnification
NOT PUBLISHED for the converter itself. The second bullet says a higher magnification factor is reached by using the camera’s 2× DIGITAL zoom, which is a function of the camera and not of this glass. Every other page on this shelf leads with a factor — 1.4× or 2× — and this one leads with the camera’s crop
Lenses named as compatible
No lenses: two cameras. The first bullet says it is compatible only with the DJI Osmo Pocket 4 and Pocket 3, and the title says the same. This catalogue carries the Osmo Pocket 4 on its gimbal shelf, so the narrowest compatibility statement on this shelf is also the easiest to check
Light loss in stops
Not published. The intro above gives the arithmetic for converters that sit between a lens and a body — one stop for a 1.4×, two for a 2× — and this one attaches magnetically to the front of a fixed-lens camera, where that arithmetic does not apply. The page gives no figure either way
Autofocus limits stated
None. On a camera whose lens and body are one piece there is no aperture for the converter to reduce, and the page makes no claim about focus at all
Added length
Not published. The fourth bullet calls the lens light and slim and gives no millimetres — and on a pocket gimbal, length is exactly what decides whether it still fits in a pocket
Sealing
Not claimed as sealing. The third bullet describes multiple coatings that resist water, scratches and fingerprints, which protects the glass rather than the joint. Three converters on this shelf claim dust and splash protection; this is not one of them
Published weight
Not published — and not one of the six converters on this shelf publishes a weight, though the intro above asks for it

  • Four elements in three groups, multi-coated against water, scratches and fingerprints
  • A magnetic mount, so nothing is threaded onto a gimbal-mounted lens
  • No optical magnification figure anywhere on the page

Best for: An Osmo Pocket 3 or 4 used for interviews and distant subjects, where a longer view is wanted without cropping into the sensor.

On the listing

Five bullets. Designed for the Osmo Pocket 4 and 3 and compatible with nothing else, called an indispensable tool for creators and influencers shooting point-of-view footage with Creator Combo accessories; a higher magnification factor reached by using the camera’s 2× digital zoom for distant subjects with fine detail, named for portrait and nature photography; multi-coated HD optical glass in four elements and three groups for sharpness, with coatings against water, scratches and fingerprints; a fast magnetic attachment that snaps directly to the camera, with a note to remove the lens before switching the camera off and to fit no protective film and no filter over it; and one tempered glass screen protector included, protecting the touchscreen without affecting its sensitivity.

Where the factor should be, a digital zoom

The camera’s 2× crop is not this converter’s magnification. One is a sensor being sampled more narrowly; the other is glass bending light. The page names the first and never names the second.

Two cameras, and no lens

The narrowest compatibility statement on this shelf, repeated in the title and the first bullet. It is also the only one a buyer can verify in a second.

A magnet instead of a thread

Threading a ring onto a gimbal-mounted lens works against the stabilising motor. A magnet lands square with no twisting force.

Three rules in one bullet

Take it off before powering down, add no film, add no filter. Instructions like these are usually learned from a broken arm rather than a listing.

What this fits

More teleconverters

  • OM System MC-14 teleconverter showing its slim housing and metal bayonet

    OM SYSTEM 1.4×, 15 mm of housing height

    Fifteen millimetres thick, sealed on a metal bayonet, 1.4× for M.Zuiko PRO telephotos — the only converter on this shelf that publishes how much it adds.

    Magnification
    1.4×, in the first bullet, named for sport, nature and wildlife photography. The intro above gives the cost of a 1.4× as one stop; the page does not repeat it
    Lenses named as compatible
    In the TITLE only — the M.Zuiko ED 40-150 mm and 300 mm PRO — and in none of the five bullets, which say merely "your compatible lenses". The intro above explains why the list matters more than the mount: a converter protrudes, and an unlisted lens can meet it with its rear element
    Light loss in stops
    Not published. Only the 169 € Viltrox on this shelf states the figure, and it states two stops for a 2×. A 1.4× costs one, by the arithmetic in the intro above, and this page leaves the reader to apply it
    Autofocus limits stated
    No limit, and a claim: the fifth bullet promises fast autofocus and stable handheld telephoto shots, with clear images at longer shutter speeds without a tripod. The buying advice on this shelf asks for the minimum aperture the body’s autofocus is specified to, and no page here supplies it
    Added length
    PUBLISHED: 15 mm of housing height, in the third bullet, described as particularly slim and said to fit in any camera bag. It is the only dimension published anywhere on this shelf, and it is the figure that decides whether the converter lives in the bag or gets left at home
    Sealing
    Dust- and splash-protected with a high-grade METAL BAYONET, in the second bullet, named for use in any weather and for travel in the open. The intro above asks whether sealing carries across the joint, and a sealed converter between a sealed lens and a sealed body is what keeps the chain intact
    Published weight
    Not published, as on all six converters here — on the one page that publishes a thickness
    Amazon reference
    B0FS25M28G (same reference on 6 Amazon marketplaces)
    EAN
    4545350054458
    • Fifteen millimetres of housing height, the only dimension published on this shelf
    • Dust and splash protection on a metal bayonet, so the sealed chain is not broken
    • The compatible lenses appear in the title and in none of the bullets

    Best for: An M.Zuiko PRO telephoto used outdoors in bad weather, where 15 mm in the bag and a sealed joint both matter.

  • Sigma TC-2001 2× teleconverter with its Canon EF mount

    Sigma 2×, SLD glass, sealed — no lens list

    Three hundred and forty-nine euros for a sealed 2× converter with Special Low Dispersion glass — and five bullets that name no lens, no stop and no gram.

    Magnification
    2.0×, in the second bullet. A 300 mm becomes a 600 mm, and the maximum aperture moves two stops with it
    Lenses named as compatible
    NONE — and on a 2× converter that is the gap that matters most. The title gives the Canon EF mount and the five bullets give nothing: no list, no range, not even a phrase like "L-series above 135 mm". The intro above is explicit that makers publish a list rather than a mount specification because a converter protrudes, and that fitting one to an unlisted lens can mean contact with the rear element. The 169 € Viltrox on this shelf names five lenses and puts "only" in front of them
    Light loss in stops
    Not published. Two stops, by the arithmetic the intro above gives for every 2×: an f/2.8 lens works at f/5.6, an f/4 at f/8. The page does not mention it, and at 349 € that is a considerable omission
    Autofocus limits stated
    Autofocus is not mentioned at all, in any bullet — neither claimed nor qualified. On a 2× that turns f/4 into f/8 this is the specification a buyer most needs, and the page is silent
    Added length
    Not published. The fifth bullet says compact and light and gives no millimetres, where the 323 € OM SYSTEM publishes 15 mm
    Sealing
    Dust- and splash-protected, in the fourth bullet. One of three converters on this shelf to claim it
    Published weight
    Not published — on a bullet that calls it light. As on all six converters here

    EAN
    0085126870546
    • Special Low Dispersion elements, named as a material rather than as a coating
    • Dust and splash protection, at the price level where this shelf starts claiming it
    • Not one compatible lens named, in five bullets, on a converter that protrudes

    Best for: A buyer who has already confirmed elsewhere that their lens accepts this converter, and who wants Special Low Dispersion glass in the joint.

  • Viltrox C-AF 2X II teleconverter with its aperture lever and USB port

    VILTROX 2× for Canon EF, exposure factor about 4

    A 2× converter for Canon EF that publishes both things this shelf asks for and rarely gets: the light it costs — two stops — and the five lenses it fits.

    Magnification
    2×, in the first bullet, doubling the focal length of Canon EF lenses. A 100-400 mm becomes a 200-800 mm, which is the reason anybody buys one
    Lenses named as compatible
    PUBLISHED, and published as a limit: the second bullet says it is compatible ONLY with L-series fixed focal lengths of 135 mm and above, plus the EF 70-200 mm f/2.8L, the f/2.8L IS, the f/4L and the EF 100-400 mm f/4.5-5.6L. The intro above explains why the list is the gate rather than the mount: a converter protrudes, and fitting one to an unlisted lens can mean contact with the rear element
    Light loss in stops
    PUBLISHED — an exposure factor of about 4, which the first bullet itself translates as the equivalent of 2 apertures. It is the only page on this shelf to state the cost, and it matches the arithmetic the intro above gives for every 2×: an f/2.8 lens behind it works at f/5.6, an f/4 at f/8
    Autofocus limits stated
    Autofocus is claimed — the third bullet says the lens autofocus function is supported, with improved performance, fast focusing and reliable subject tracking — and NO minimum aperture is stated. The buying advice on this shelf asks for exactly that figure, because an f/4 lens becomes f/8 here and some bodies stop focusing there
    Added length
    Not published. Seven elements in four groups is the optical construction, given twice; how much further forward the lens sits is not
    Sealing
    Not claimed. The 323 € OM SYSTEM, the 349 € Sigma and the 479 € Canon on this shelf all claim dust and splash protection; this one claims coatings against ghosting and flare instead
    Published weight
    Not published, as on all six converters here

    B08GC59HV2 (same reference on 6 Amazon marketplaces)
    EAN
    0086291917067
    • Two stops of light loss published, and translated into apertures on the page itself
    • Five lenses named, with the word "only" in front of the list
    • No minimum aperture for autofocus, on a converter that turns f/4 into f/8

    Best for: One of the five Canon EF telephotos named on the page, when 400 mm has to become 800 and two stops can be spared.

Elsewhere in the camera bag

  • Amazon Basics 67 mm UV filter lying flat on a lens cap

    Amazon Basics 67 mm, no coating or thickness published

    Nine euros for a 67 mm protective lid whose five bullets describe what it is for four times over, and its construction not once.

    Thread size
    67 mm, in the title and the fourth bullet, which calls it compatible with a wide range of lenses. Sixty-seven millimetres is the thread of a great many standard zooms, and it is the size the buying advice above says to buy for and step down from
    Glass
    NOT SPECIFIED. No origin, no type, no grade — where the 11 € K&F and the 13 € PROfezzion on this shelf both name Japanese optical glass and the 8 € Hama names optical glass in a black metal frame
    Coating description
    NONE, and this is the specification whose absence costs most. An uncoated filter reflects light between its surfaces and the lens, which lowers contrast and can throw a ghost of a bright source into the frame. The hub above is blunt about it: an uncoated filter in front of a good lens is a downgrade you pay for. The other three filters here publish 2, 12 and 18 layers
    Frame thickness
    Not published. The 8 € Hama gives 3.4 mm and the 13 € PROfezzion 3 mm; on a 67 mm filter destined for a standard zoom, thickness is what decides whether the corners darken at the wide end
    Material
    Not named. Neither the frame metal nor the glass is described anywhere in five bullets
    Front thread provision
    Not mentioned. Whether a hood, a cap or a second filter screws onto the front is left unstated — the 8 € Hama names all three
    Stated transmission figure
    Not published
    Amazon reference

    EAN
    0848719099393
    • Sixty-seven millimetres, the thread the buying advice above says to standardise on
    • Nine euros, the cheapest 67 mm lid on this shelf
    • No coating described at all, on glass that sits in front of every photograph

    Best for: A lens that lives in a bag with sand and keys, where a 9 € replaceable lid is the point and image quality is carried by the hood instead.

  • Hama 49 mm UV filter in its black metal frame beside its plastic box

    Hama 49 mm, one coating layer per side, 3.4 mm frame

    Eight euros for a 49 mm colour-neutral UV filter with one coating per side, a 3.4 mm metal frame and a box — and a front thread that still takes a hood or a cap.

    Thread size
    49 mm, in the title — the smallest on this shelf, where the three others are 67 mm. Forty-nine millimetres is the thread of small primes and older kit lenses, and the buying advice above prefers the largest thread in the bag with step rings below it. This is the filter bought for one small lens
    Glass
    Optical glass in a black metal frame, in the third bullet, described as colour-neutral. No glass origin is named, where the 11 € K&F and the 13 € PROfezzion both claim Japanese optical glass
    Coating description
    COUNTED, and precisely: one coating layer on EACH SIDE — a two-fold coating, as the title has it. That is the lowest count on this shelf, against twelve layers on the PROfezzion and eighteen on the K&F, and it is stated plainly rather than dressed up
    Frame thickness
    3.4 mm, in the fifth bullet, described as a flat mount. Only two pages on this shelf publish a frame figure; the PROfezzion is 3 mm and the two others publish none. Thickness is what decides whether a wide lens sees the ring
    Material
    A black metal frame around a glass lens, in the third bullet. Black inside the frame is what stops light bouncing between filter and lens, and the colour is worth the mention
    Front thread provision
    YES, and it is the only page here that spells out what the front thread is for: the fourth bullet says further filters, a lens hood or a lens cap screw straight on. A filter without a front thread ends the stack; this one does not
    Stated transmission figure
    NOT PUBLISHED. The 13 € PROfezzion is the only filter on this shelf to give one, at 99.5 per cent minimum. With one coating layer per side, the loss here will be larger, and the page does not say by how much
    Amazon reference
    B00006JEAY (same reference on 6 Amazon marketplaces)
    EAN
    4007249700490
    • A published 3.4 mm frame and a counted coating — one layer per side
    • A front thread stated to take another filter, a hood or a cap
    • One coating layer per side, against twelve and eighteen elsewhere on this shelf

    Best for: A small 49 mm prime or an older kit lens that needs a lid over the front element, where a hood or a second filter still has to go on top.

  • K&F Concept 67 mm UV filter with its green-tinted coating catching the light

    K&F CONCEPT 67 mm, Japanese glass, 18 nano layers

    Eighteen layers of nano coating on Japanese glass for 11 €, with a claim to cut chromatic aberration — and a sales-rank citation where a seventh specification would go.

    Thread size
    67 mm, in the title, and the fifth bullet says it suits all lenses with a 67 mm thread, naming Canon, Nikon, Sony, Samsung and Fuji
    Glass
    JAPANESE OPTICAL GLASS, in the second bullet, credited with first-class light transmission, improved optical clarity and colour fidelity. The same claim the 13 € PROfezzion on this shelf makes; the 9 € Amazon Basics names no glass at all
    Coating description
    EIGHTEEN LAYERS of green anti-reflective nano coating, in the third bullet — the highest count on this shelf, against twelve on the PROfezzion and two on the Hama. The same bullet claims the coating blocks ultraviolet light, raises contrast and eliminates light haze at sea or in high mountains
    Frame thickness
    NOT PUBLISHED as a figure: the fourth bullet calls it an extremely thin filter and leaves it there. The 8 € Hama publishes 3.4 mm and the 13 € PROfezzion 3 mm, so the one page here claiming thinness is the one that does not measure it
    Material
    Not named for the frame. The glass is specified and the ring is not
    Front thread provision
    Not mentioned
    Stated transmission figure
    NOT PUBLISHED — which is the odd gap on a page that counts eighteen coating layers. Layers exist to raise transmission, and the 13 € PROfezzion publishes the resulting figure at 99.5 per cent minimum
    Amazon reference
    B0C1YZBPRK (same reference on 6 Amazon marketplaces)
    EAN
    6942052514675
    • Eighteen nano layers on named Japanese optical glass, for 11 €
    • A stated effect on chromatic aberration, which no other filter here claims
    • Calls itself extremely thin and publishes no thickness

    Best for: A 67 mm standard zoom used in bright coastal or mountain light, where haze and reflections matter more than the gap to the 9 € Amazon Basics.
