Sixteen channels, and one transmitter fires many receivers

PROfezzion 50 m radio, 16 channels, 5 modes, batteries included

Thirty-five euros for a 50 metre radio release with sixteen channels and five modes including bulb — batteries included, and one transmitter fires several cameras.

PROfezzion wireless shutter release transmitter and receiver with its tripod clip

PROfezzion 50 m radio, 16 channels, 5 modes, batteries included

Thirty-five euros for a 50 metre radio release with sixteen channels and five modes including bulb — batteries included, and one transmitter fires several cameras.

Connection type
2.4 GHz RADIO, in the second bullet — a transmitter and a separate receiver that plugs into the camera. Radio needs no line of sight, which the first bullet names directly: the shutter fires at up to 50 metres without a clear view of the camera
Sockets and bodies named
MORE THAN FORTY, in the fifth bullet — the longest compatibility list on this shelf by a wide margin. It runs from the EOS R and RP through the R6 Mark III, R7, R8, R10, R100 and R50V to the 2000D, 1500D, 850D, 90D and 77D, the M6 Mark II and M5, and then leaves Canon entirely for Contax 645 and N1, Samsung NX, and Pentax K-3 II, 645D, K500 and K200D — bodies sharing the same release socket
Half-press support
Not named as half-press, but answered in a better way: the third bullet says the RECEIVER ITSELF FUNCTIONS AS A CABLE SWITCH. Unplugged from the transmitter’s control, it becomes a wired release on the camera — which is where a half-press lives
Intervalometer functions
NONE, and the page is explicit about a second limit in the same bullet: IT DOES NOT CONTROL VIDEO START AND STOP. What it does give is FIVE MODES — single shot, a 5-second delay, a 3-frame burst, unlimited burst, and BULB for long exposures
Stated range
50 METRES, published in the first and second bullets, over 16 CHANNELS. Channels matter where several photographers work together: sixteen means two people can fire their own cameras in the same room without triggering each other
Power source
AAA batteries for BOTH units, and the fourth bullet says they are INCLUDED — which on this shelf is rare enough to note. The same bullet adds a detachable clip for fixing the transmitter to a tripod leg

  • Fifty metres over sixteen channels, with one transmitter able to fire several receivers
  • Five modes including bulb, and the receiver works alone as a cable switch
  • It does not control video start and stop, stated by the maker

Best for: Wildlife or group work at a distance, and long exposures — where bulb mode and 50 metres matter more than a timer.

On the listing

Five bullets, each opening with a loudspeaker. A wireless remote reducing camera shake and allowing hard-to-reach subjects to be photographed, firing the shutter without line of sight at up to 50 metres, with 16 available channels; support for several shooting modes, releasing the shutter wirelessly in five modes — single shot, 5-second delay, 3-frame burst, unlimited burst and bulb — working at 2.4 GHz, with a caution that it does not control video start and stop; easy setup, light and portable, one transmitter able to fire several receivers, with the receiver itself acting as a cable switch; a user-friendly configuration with a detachable clip for attaching the transmitter to a tripod leg, and AAA batteries for transmitter and receiver included; and a compatibility list naming more than forty Canon EOS, M-series, Contax, Samsung NX and Pentax bodies.

Fifty metres, through anything

Radio rather than infrared. No line of sight, no standing in front of the camera — the first bullet says the shutter fires without a clear view, which is what a hide or a crowd requires.

Sixteen channels, and several receivers at once

Two photographers in one room do not trigger each other. And one transmitter firing three cameras is how the same moment is taken from three angles.

Bulb, in the mode list

Thirty seconds is where most cameras stop. Bulb is how a four-minute exposure is made, and a remote is the only comfortable way to hold it.

The receiver is also a cable release

Unplugged from the radio, it is a wired switch on the camera. Two products for the price of the parts.

Batteries in the box, for both units

Rare enough to note. And a clip for the tripod leg, so the transmitter is not in a pocket when it is needed.

What it will not do

Start and stop video. The maker says so in its own second bullet.

More remote shutter releases

  • Rollei wireless remote release with its illuminated OLED display lit

    Rollei Radio intervalometer, OLED, 50 m, to 99 h 59 min 59 s

    Thirty-nine euros for the only intervalometer here: an OLED display, 50 metres, exposures to 99 hours and two setups stored — for Nikon.

    Connection type
    RADIO, wireless, with an ILLUMINATED OLED DISPLAY and illuminated buttons, in the second bullet — which makes the point that matters for the work this does: a timer is programmed in the dark, at the start of a night exposure, and a lit screen is the difference between setting it correctly and guessing
    Sockets and bodies named
    NIKON DSLM AND DSLR, in the title, with no individual model named anywhere in nine bullets. It is the vaguest compatibility on this shelf — the 35 € PROfezzion names more than forty bodies — and Nikon uses several different release sockets, so the exact plug has to be confirmed elsewhere
    Half-press support
    Not stated
    Intervalometer functions
    THE ONLY ONE ON THIS SHELF, and the fullest specification here: INTERVAL SHOOTING for time-lapse sequences; a TIMED RELEASE PROGRAMMABLE UP TO 100 HOURS IN ADVANCE; UNLIMITED BURST; and MANUAL LONG EXPOSURE adjustable from ONE SECOND to 99 HOURS 59 MINUTES 59 SECONDS. Four functions, each in its own bullet
    Stated range
    50 METRES, in the third bullet, for both remote release and interval work — matching the 35 € PROfezzion and five times the 10 m of the 8 € phone remote
    Power source
    NOT PUBLISHED, in nine bullets — which on a device meant to run a hundred-hour timer is the specification most worth knowing. A remote whose cell dies at hour ninety has taken no photograph at all

    • The only intervalometer here: time-lapse, timer, bulb to 99 hours, unlimited burst
    • An illuminated OLED display and lit buttons, for programming in the dark
    • No power source published, on a device that runs hundred-hour programmes

    Best for: Star trails, time-lapse and any exposure measured in hours, on a Nikon body whose release socket has been confirmed.

  • Pair of ATUMTEK Bluetooth camera remotes with a wrist strap attached

    ATUMTEK Two Bluetooth 5.2 remotes, 10 m, CR2032

    Eight euros for two Bluetooth 5.2 phone remotes with a published 10 m range, 20,000 shots from one CR2032 and their dimensions on the page.

    Connection type
    BLUETOOTH 5.2, in the first bullet, claimed to give lag-free operation. It is the only wireless standard on this shelf that is not a proprietary radio or infrared — and it exists because this remote talks to a phone rather than to a camera
    Sockets and bodies named
    NO CAMERA. The second bullet claims compatibility with most Android and Apple smartphones on the market, and names nothing else. It sits on this shelf as the phone answer to the same job — and the hub above compares connection, range and power, all of which this page publishes
    Half-press support
    Not applicable. A phone has no two-stage shutter button, so there is nothing to half-press: focus is set by tapping the screen before the remote is used
    Intervalometer functions
    NONE. The 39 € Rollei on this shelf is the only intervalometer here
    Stated range
    UP TO 10 METRES, in the first bullet — the shortest published range on this shelf, against 50 m for two of the camera remotes. Ten metres is a group photograph or a self-portrait, which is what a phone remote is for
    Power source
    A CR2032 button cell of 210 mAh, in the third bullet, claimed to take OVER 20,000 PHOTOGRAPHS. Publishing a shot count rather than a battery life is the right unit for this product, and 20,000 means the cell outlasts the interest

    • Two remotes for 8 €, with a published 10 m range
    • Over 20,000 shots from one CR2032, and the cell is included
    • Phones only — no camera, no socket, no body named

    Best for: Group photographs and self-portraits taken on a phone on a tripod, where two remotes mean one lives in a coat pocket.

  • Canon RC-6 infrared remote release, black, seen from the front

    Canon RC-6 infrared — three bullets, one body named "t1i"

    Sixteen euros for Canon’s own infrared remote, from a page of three bullets that names one camera in lower case and lists its contents twice.

    Connection type
    INFRARED — the only one on this shelf, and the constraint that defines it: an infrared remote needs LINE OF SIGHT to the sensor on the FRONT of the camera. It works from in front, where you are standing to be photographed, and not from behind. Every other remote here uses radio or Bluetooth and works through a wall
    Sockets and bodies named
    ONE, and written as "t1i" in lower case — the EOS Rebel T1i, a camera from 2009. The RC-6 in fact works with a long list of Canon bodies carrying an infrared receiver, and the page names a single one of them, in the wrong case
    Half-press support
    Not stated. The RC-6 has a two-position switch — immediate release and a two-second delay — and the page mentions neither
    Intervalometer functions
    None
    Stated range
    NOT PUBLISHED. Two remotes on this shelf publish 50 m and one publishes 10 m; the original publishes nothing, on a technology whose range is its main limitation
    Power source
    NOT PUBLISHED. The RC-6 uses a CR2032, and the page does not say so — where the 8 € ATUMTEK publishes the cell, its capacity and its shot count

    EAN

    • Canon’s own remote, so the infrared protocol is the correct one
    • The RC-6 part number identifies it unambiguously
    • Three bullets, and the contents are listed twice

    Best for: A Canon body with an infrared receiver, standing in front of the camera — bought by part number because the page says nothing else.

Elsewhere in the camera bag

  • 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

    B00NIHBM9U (same reference on 6 Amazon marketplaces)
    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

    • 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

    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.
