A hundred metres, and no unit to lose

YONGNUO RF-603NII transceivers, 100 m, identical and interchangeable

Transceivers rather than a transmitter and receiver — every unit does both jobs and any two work together — with a 100 m range, the longest on this shelf, for 46 €.

Yongnuo RF-603NII transceiver pair in black with metal shoes and locking wheels

YONGNUO RF-603NII transceivers, 100 m, identical and interchangeable

Transceivers rather than a transmitter and receiver — every unit does both jobs and any two work together — with a 100 m range, the longest on this shelf, for 46 €.

Radio system named
Only as a product line: the RF-603NII, stated in the first bullet to be backwards compatible with the earlier RF-603. No protocol and no frequency is named. What is named instead is a design principle — the units are transceivers, identical and interchangeable, so any unit can transmit or receive. Extra units are sold separately, which is how the set grows
Camera mounts supported
Nikon, named in the title across the D1 to D800 range. The fourth bullet describes the release cable supplied for connecting a transceiver to the camera, and the first mentions a shoe with a screw clamp so the unit cannot slide sideways off the camera
Channel and group counts
Not published. Five long bullets describe the transceiver principle, the two firing arrangements, the camera release function and the multi-flash use, and no channel or group figure appears at all — the only page on this shelf to publish neither
Remote power control
None. The set fires flashes and cameras, and nothing describes adjusting a light’s power remotely
Metering and sync modes claimed
None claimed, and no sync ceiling is published either — unusual on this shelf, where 1/250 s and 1/160 s figures appear elsewhere. The fourth bullet does describe a two-stage release button, half press to focus and full press to fire, and says long exposures, continuous frames and video start and stop are all possible with the right camera setting
Power source
Not published. The first bullet mentions a side-mounted on-off switch as an improvement over the previous model, and no cell type or count appears anywhere

  • A 100 m range, more than three times the 30 m claimed by everything else here
  • Transceivers: identical units, any one transmitting or receiving, interchangeable and expandable
  • No channel or group counts published at all

Best for: Firing a flash or a camera from a distance on a Nikon body, where the 100 m range and the ability to add identical units matter more than channels.

On the listing

Five long bullets. Improvements over the earlier RF-603: a shoe with a screw clamp so the transceiver cannot slide sideways, and a side-mounted on-off switch, with backwards compatibility stated; a bullet on firing camera and flash together, with a transceiver between flash and camera on the shoe and a second unit releasing both; use as a flash trigger, one transceiver on the camera shoe and the flash in a second, at up to 100 m, with several flashes possible and studio heads connected by a 6.3 or 3.5 mm jack cable that is not included; use as a camera release, either through the supplied cable or by mounting a transceiver on the shoe, with a two-stage button for focus and fire and support for long exposures, continuous frames and starting and stopping video; and a closing bullet on firing several flashes, noting that extra transceivers are sold individually, that the units are identical and interchangeable, that the range reaches 100 m, and that the metal shoe carries an integrated tripod thread.

Identical units, either job

There is no transmitter to lose. Any unit transmits, any unit receives, and a third bought later is the same part as the first two. That is a different purchasing model from the fixed pairs elsewhere on this shelf, and it is the reason this design has survived so long.

A hundred metres

Three times the claim on every other page here. At studio distances the value is margin rather than reach — a link with that much headroom does not drop behind a softbox.

A screw clamp and a tripod thread

Two small pieces of metalwork that matter. The clamp stops the unit sliding out of the shoe mid-session; the thread lets a receiver stand on a tripod or a light stand by itself, with the flash on top of it.

The two-stage button

Half press to focus, full press to fire, from up to a hundred metres away. With the right camera setting the same button covers long exposures, bursts and video start and stop — which makes this a camera remote as much as a flash trigger.

Three blanks, and a cable to buy

No channels, no groups, no sync speed published. And the jack cable for a studio head is stated as not included, where two cheaper sets on this shelf supply one.

Availability

Between 46 € and 53 € on the German, French, Italian and Spanish Amazon stores when this page was last checked.

The British Amazon store carry it too, priced in local currency. Those amounts are deliberately absent from the range above, which reads euro stores only.

Nothing came back from the American Amazon store at all, so the button for that country runs a search instead of opening an entry that is not there.

Everything in this section is the figure Keepa carried on the day of the last update to this page. Availability and prices shift without notice.

More flash triggers

  • JJC trigger set laid out with one transmitter, two receivers and its cables

    JJC One transmitter, two receivers, Nikon release cable

    A 36 € set that fires flashes and releases the shutter, with two receivers, both cables and the batteries in the box — and a compatibility list that reaches back to the F5.

    Radio system named
    None. Five bullets describe the contents, the compatible cameras, the compatible flashes, the dual function and the specifications, and no radio system or frequency appears. What the page does instead is name the hardware it works with on both sides, which is a different kind of assurance — concrete about the present, silent about what could be added later
    Camera mounts supported
    Nikon, named exhaustively in the second bullet — Z9, D500, D4S, D5, D810, D850, D800, D700, D300s, D300, D200, D100, D4, D3S, D3, D3X, D2H, D1H, D2Xs, D2x, D1X, D1, F100, F90x, F90, F6, F5 — plus Fujifilm FinePix S3 Pro and S5 Pro and the Kodak DCS-14n. A list that includes film bodies is unusual and tells you what the release cable fits
    Channel and group counts
    16 adjustable radio channels, in the fifth bullet, with no groups published. The same position as most of this shelf: enough channels to stay clear of interference, no means of controlling lights separately
    Remote power control
    None. The set fires flashes and releases shutters, and nothing on the page describes changing a flash’s power from the transmitter
    Metering and sync modes claimed
    Sync to 1/250 s, in the fifth bullet, and no metering or high-speed sync. The fourth bullet claims something else worth having: it can fire speedlights and studio flashes at once, and supports several flashes firing together
    Power source
    Supplied — a 23A cell and an AAA alkaline cell are in the box list, which is the only page on this shelf to include batteries at all. It does not say which unit takes which, and the counts for a three-piece set are not broken down

    EAN

    • Two receivers in the box, so two lights are covered by one purchase
    • It doubles as a camera remote release, with the Nikon shutter cable supplied
    • No system and no frequency named anywhere

    Best for: A Nikon photographer lighting a still life or a portrait with two manual heads, who also wants a wireless shutter release from the same box.

  • Andoer WanSen AC-04 flash trigger set with transmitter, receiver and sync cable

    Andoer WanSen AC-04, 4 channels, 30 m

    The cheapest trigger here at 17 €, with four channels, a 1/250 s sync claim and a cable for cameras with no hot shoe — and no system, no groups and no stated power source.

    Radio system named
    None. Five bullets describe a set, a sync speed, a fit, a cable and a range, and no radio system and no frequency appears — less even than the 433 MHz stated by the trigger above it. What arrives in the box works together, and the page gives no basis for saying what else ever will
    Camera mounts supported
    Canon, Nikon and Sony reflex bodies with a single-point hot shoe, in the third bullet. Single-point means the central firing contact only, so nothing is passed but the signal to fire — and the fourth bullet adds a connecting cable for cameras and transmitters, so a body without a usable shoe can still trigger the set
    Channel and group counts
    Four channels, in the first bullet, and no groups. It is the smallest channel count on this shelf — the trigger beside it offers sixteen — and four is enough to avoid a clash in a quiet room and not in a busy hall
    Remote power control
    None. Nothing on the page describes adjusting a light from the transmitter
    Metering and sync modes claimed
    A highest sync speed of 1/250 second, in the second bullet, and nothing else: no metering, no high-speed sync, no named modes. For a manual studio set that is the honest minimum, and the figure is above the sync speed of many bodies
    Power source
    Not published on the listing. Neither the transmitter nor the receiver has a cell type or count named, which on a two-piece radio set is a real omission — the trigger above it at least states two AAA cells for its receiver

    • Seventeen euros, the cheapest way to get a manual flash off the camera on this shelf
    • A connecting cable supplied, so a camera without a usable hot shoe can still fire the set
    • No system and not even a frequency named, so nothing can be said about future compatibility

    Best for: Getting one manual studio head off the camera for the least money, on a reflex body with an ordinary hot shoe.

  • Godox X5F flash trigger in black, a small hot shoe unit with a locking ring

    Godox X5F for Fujifilm, Godox 2.4G X system

    A 20 € transmitter that belongs to a named system — Godox 2.4G X — fires the maker’s studio heads by name, and has no power switch and no channel count.

    Radio system named
    The Godox 2.4G X system, named in the title and the third bullet, which then lists what it reaches: the AD100Pro II, AD200Pro II, AD600Pro II, AD600BM II, iT30Pro, V100, V480 and the Lux Master models. This is exactly what the hub above asks for — a system named on the box, with the lights that speak it enumerated, so the consequences of the purchase are visible before it is made
    Camera mounts supported
    Fujifilm, named in the title and listed body by body in the second bullet: X-Pro2, X-T20, X-T2, X-T1, GFX50s, GFX50R, X-T30, X-T4, X-T3, X-S20, X-T5, X-Pro1, X-T10, X-E1, X-A3, X100F and X100T. One camera system, named explicitly — which is the gate the hub above describes, since the contacts behind the centre pin differ between makers
    Channel and group counts
    Not published. Five bullets name the system, the cameras, the compatible lights, the mounting and the battery, and no channel or group figures appear. The cheapest trigger on this shelf publishes 16 channels; this one publishes none, which is the odd gap on an otherwise precise page
    Remote power control
    Yes, but narrowly, and the third bullet is careful about it: used off-camera the X5F can adjust the power of the iT32 only. It will fire other Godox X-system lights and cannot change their power levels. That is a real limitation stated plainly rather than left to be discovered
    Metering and sync modes claimed
    High-speed sync support, named in the first bullet, and TTL in the product description. No sync ceiling in fractions of a second is published here — the flash it partners quotes 1/8000 s — and no metering protocol is named beyond TTL for Fujifilm
    Power source
    A built-in 3.8 V 100 mAh lithium cell that charges only when the unit is attached to the iT32, about 3 hours to fill, giving up to 16 hours of standby. The closing bullet also states there is no physical power switch: status is shown by coloured LEDs, and the charge level appears in the flash’s own menu

    • A named system with its compatible lights listed by model, from the AD100Pro II to the V480
    • Fujifilm bodies named individually rather than described as universal
    • No channel or group counts published anywhere

    Best for: A Fujifilm body already inside the Godox X system, where the named light list is the reason to buy and the iT32 is the flash it drives.

Elsewhere in the camera bag

  • 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

    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

    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

    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.

  • Canon E-58II black lens cap lying face up

    Canon E-58II, 58 mm — three bullets, two irrelevant

    Four euros for Canon’s own 58 mm cap, from a listing whose three bullets are a colour and two camera specifications that have nothing to do with a cap.

    Cap type
    A front cap — the Canon E-58II, identified by part number in the title. The "II" marks Canon’s revised centre-pinch design, replacing an older rim-grip cap, which is the single most useful fact about it and appears nowhere in the bullets
    Thread or mount fit
    58 mm, carried only by the part number: E-58II. No bullet states a diameter, and no lens is named — where the 4 € JJC on this shelf names nine
    Pinch mechanism
    NOT STATED. The E-58II is a centre-pinch cap, which is why it can be removed inside a hood, and the page does not say so
    Tether provision
    NONE. No cord, no hole and no keeper
    Material
    Not named
    Pack contents
    Not stated. What the three bullets do contain is: "colour: black"; "Intervall-Aufnahme Y" — interval shooting, yes; and "USB Konnektivitätstechnologie" — USB connectivity technology. The last two are fields from a camera-body template, published on the listing for a piece of plastic with no electronics in it

    EAN
    4960999795904
    • Canon’s own part, so the fit and the pinch action are the originals
    • The E-58II part number identifies it unambiguously
    • Two of its three bullets are camera specifications — interval shooting and USB

    Best for: Replacing a lost original cap on a 58 mm Canon lens, bought by part number.
