Four cameras named, not four lenses

Fujifilm 1.4×, to 50 mm equivalent, for four X100 bodies

Two hundred and thirty-nine euros for a 1.4× converter that takes the X100 series to a 50 mm equivalent — five short bullets, four named cameras, and no element count.

Fujifilm TCL-X100 II silver teleconverter beside an X100 camera

Fujifilm 1.4×, to 50 mm equivalent, for four X100 bodies

Two hundred and thirty-nine euros for a 1.4× converter that takes the X100 series to a 50 mm equivalent — five short bullets, four named cameras, and no element count.

Magnification
1.4×, in the first bullet, given as extending the focal length to 50 mm in full-frame equivalent. The arithmetic is visible: 1.4 times a 35 mm equivalent is 49, and the page rounds it to 50 — which also tells the reader what lens is underneath
Lenses named as compatible
FOUR CAMERAS, not lenses: the X100, X100S, X100T and X100F, in the second bullet. It is the only page on this shelf whose compatibility list is made of bodies, and that makes it the easiest to check and the narrowest to satisfy
Light loss in stops
NOT PUBLISHED. The intro above gives one stop as the price of a 1.4× sitting between a lens and a body; this converter is sold for four cameras whose lens does not come off, and the page states no figure at all. Nothing here confirms or denies a loss
Autofocus limits stated
None. No aperture, no focus claim, no caveat — in five bullets, two of which are "silver" and a contents list
Added length
Not published
Sealing
Not claimed. The 323 € OM SYSTEM, the 349 € Sigma and the 479 € Canon here all claim dust and splash protection
Published weight
Not published, as on all six converters here

  • Four compatible cameras named outright, in a market where lists are usually absent
  • The result is published as a focal length — 50 mm equivalent — not only as a factor
  • Five bullets, of which one is the word "silver" and one a two-line contents list

Best for: An X100, X100S, X100T or X100F used for portraits, where 35 mm is too wide and a second camera is not the answer.

On the listing

Five bullets, and they are short. The focal length extended by 1.4× to 50 mm in full-frame equivalent; suitability for the X100, X100S, X100T and X100F; particular suitability for portraits; silver; and a contents list of the TCL-X100 II converter and a manual.

One point four times thirty-five is forty-nine

The page rounds to 50, and in doing so names the lens underneath. Publishing the result rather than the factor is the more useful habit, and it is rare on this shelf.

Four cameras on the list

Not four lenses. Compatibility becomes a single question with a yes or a no, which is the opposite of the 349 € Sigma here, whose page names nothing at all.

Fifty millimetres, for a face

Thirty-five takes in the room behind the subject. Fifty takes in the subject. The third bullet says portraits and stops there, which is the correct length of that argument.

What five bullets leave unsaid

No element count. No coating. No length. No weight. No light loss. The 169 € Viltrox publishes four of those five.

Between 239 € and 271 € on the German, French, Italian and Spanish Amazon stores when this page was last checked.

  • 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

    EAN
    0191073127913
    • 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.

  • 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.

Elsewhere in the camera bag

  • NEEWER GM36 low-profile ball head with its Arca plate and panning scale

    NEEWER GM36 low-profile ball head, 15 kg, Arca 38 mm

    Fifteen kilograms declared and the only Arca-compatible plate named on this shelf, on a low-profile ball head weighing 310 g at 43 €.

    Head type
    A low-profile ball head with a 36 mm ball, in the title and the first bullet, which gives the reason for the shape: a lower centre of gravity makes the head more stable. The third bullet adds 360 degrees of pan and 90 of tilt in a U-shaped notch — the cutout that lets a camera drop into portrait orientation
    Declared load
    33 lb, 15 kg, in the first bullet — the largest figure on this shelf and more than twice what any tripod in this catalogue declares. The hub above says the lower of the head and legs governs, so this head will never be the limiting part of any assembly built from these pages
    Plate standard
    Arca-compatible, 38 mm, named explicitly in the second bullet with a 1/4 inch fixing screw and rubber pads to protect the camera. It is the ONLY page of the three here to name a profile, and the hub above says to read the plate before the load figure precisely because an Arca dovetail joins what most bags already contain
    Mounting thread
    A 3/8 inch thread below with a 3/8 to 1/4 inch screw adapter supplied, in the first bullet, said to fit most tripods, monopods and sliders. Supplying the adapter matters: it is the small brass ring that otherwise lives at the bottom of a bag until it is lost
    Panning base and markings
    A separate panning foot with a 360 degree scale, in the third bullet, credited with precise and smooth panoramic work, plus a bubble level for keeping the horizon straight. A panning base independent of the ball is what lets a level pan stay level — the K&F below it describes no such base
    Locking and friction controls
    Three locking knobs, in the fifth bullet: release them to set the ball freely, turn the camera gently for a panorama, release the plate. No separate friction adjustment is named, so the ball either holds or moves
    Published weight
    310 g, in the fourth bullet, with CNC-milled aluminium alloy named as the material. Half again the weight of the K&F, for half again the declared load

    0191073122574
    • A 38 mm Arca-compatible plate, the only named profile on this shelf
    • Fifteen kilograms declared, more than twice what any tripod in this catalogue carries
    • No friction control, so the ball holds or releases with nothing in between

    Best for: Any tripod, monopod or slider in this catalogue, for a photographer who already owns Arca-profile plates and wants the head to stop being the limit.

  • 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

    • 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

    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
