Four bodies named, four cold shoes on the handle

Hersmay RSYDB1098 cage for Sony A7III, A7RIII, A9 and A7II, 230 g

Two hundred and thirty grams of aluminium cut for four named Sony bodies, with a top handle carrying four cold shoes — and a page that never says whether the battery door still opens.

Hersmay aluminium camera cage on a Sony body with its top handle and cold shoes

Hersmay RSYDB1098 cage for Sony A7III, A7RIII, A9 and A7II, 230 g

Two hundred and thirty grams of aluminium cut for four named Sony bodies, with a top handle carrying four cold shoes — and a page that never says whether the battery door still opens.

Bodies named
Four, in the title and the first bullet: Sony A7III, A7RIII, A9 and A7II. The hub above says the list of compatible models IS the specification, because a cage cut for one generation fouls the ports of the next — and makers publish models rather than dimensions. Four named bodies is a precise statement
Thread and pin provision
Multiple 1/4-20 and 3/8-16 threaded holes, in the fourth bullet, plus several ARRI-style locating mounts that prevent an accessory rotating once fitted. ARRI pins are the part that turns a single screw into a fixed orientation, and this page names them
Cold shoes
One on the cage and FOUR on the top handle, in the fourth and sixth bullets, the latter naming microphones, LED lights, monitor mounts and viewfinder mounts as what they carry. Five cold shoes is more than any small rig normally needs, which is the point of a handle designed to be built on
NATO rails
Not described. The page names threads, ARRI mounts and cold shoes, and never a NATO rail — so a handle or a side grip that expects one will need a separate adapter
Cable clamp
Not described. The hub above calls the cable clamp the part that saves a socket, because the strain of an HDMI or USB lead then falls on the clamp instead of the connector. This page does not provide for it, which on a cage sold for filming is the notable gap
Battery and card access
Not stated. The second bullet says the cage preserves access to the camera’s controls and hot shoe, and never mentions the battery door or the card slots. The buying advice for this shelf is to check that the battery door opens with the cage fitted AND that the listing says so in words — here it does not
Base profile
Not described as a tripod plate profile. The third bullet names an anti-twist design with the 1/4-20 camera screw and padding at the base to protect the camera from scratches — so the base holds the camera, and what the base itself mounts onto is unstated
Material
High-grade aluminium alloy, in the second bullet, described as a solid piece of metal highly resistant to oxidation
Published weight
230 g, in the fifth bullet, alongside strap holes for a hand strap or a neck strap and a supplied hex key with a magnetic holder so it cannot be lost
Amazon reference

EAN

  • Four Sony bodies named explicitly, which is what a cage specification actually is
  • Four cold shoes on the top handle plus one on the cage, with ARRI locating mounts against rotation
  • No cable clamp, on a cage sold for filming

Best for: One of the four named Sony bodies used for video, where a handle with somewhere to put a microphone, a light and a monitor is the whole reason to fit a cage.

On the listing

Six bullets. Designed specifically for Sony A7III, A7RIII, A9 and A7II mirrorless cameras, protecting and stabilising the body; access preserved to the camera’s controls and hot shoe, in a high-grade aluminium alloy highly resistant to oxidation; an anti-twist design with the 1/4-20 camera screw and padding at the base against scratches; a cold shoe mount and multiple 1/4-20 and 3/8-16 threaded holes, with several ARRI mounts preventing accessories from twisting; a light design at 230 g with strap holes for a hand or neck strap and a supplied hex key with a magnetic holder; and a top handle for handheld work, carrying a large rig with four integrated cold shoes for microphones, LED lights, monitor mounts and viewfinder mounts.

Four bodies, named

That list is the specification. A cage is milled around one camera; the next generation moves a port by two millimetres and the cage fouls it. The hub above says makers publish models rather than dimensions, and this page publishes four.

Four cold shoes on the handle

A microphone, a light, a monitor, a receiver — without a single one of them competing for the camera’s own hot shoe, which stays free. Five shoes in total is what a rig is built from.

ARRI pins, against the thing that actually goes wrong

One screw holds an accessory until it is knocked, and then it swivels. Two locating pins beside the thread mean it can only sit one way. It is a small feature and it is the one that keeps a monitor level after an hour of handheld work.

Two hundred and thirty grams, and a key that stays put

The weight is published, and the hex key is held magnetically in the base — which is where every other hex key in this trade is not, at the moment it is needed.

What the page never mentions

No cable clamp, so an HDMI lead pulls on its own socket. No word on the battery door or the card slots, which the buying advice for this shelf says to check and to insist is stated in words.

Availability

About 60 € on the German, French and Italian Amazon stores when this page was last checked.

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

Listed in the Spanish Amazon catalogue with nothing on sale against the entry: the camera has a page there and no seller behind it.

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 camera cages

  • NEEWER universal camera cage in black and red with two hand grips and 15 mm rods

    NEEWER Universal cage, two handles, 15 mm rod base

    A universal cage at 63 € whose real specification is its rod base — two 15 mm rods at 60 mm spacing — carrying a follow focus, a matte box or a lens support.

    Bodies named
    None precisely, and that is the trade. The first bullet claims wide compatibility and lists examples — Canon 5D Mark II and III, 600D, 700D, Nikon, Sony, Fujifilm, Pentax and other reflex bodies and camcorders — rather than a definitive set. The hub above says the model list IS the specification for a cage; a universal cage replaces it with an adjustable clamp and a screw, which fits more cameras and fits none of them exactly
    Thread and pin provision
    Multiple 1/4 inch and 3/8 inch threaded holes on the top of the cage, in the fourth bullet, for articulating arms, microphones, cold shoe mounts and field monitor mounts. No ARRI locating pins are named, so an accessory is held by its screw alone and can rotate
    Cold shoes
    Not counted. The fourth bullet names cold shoe MOUNTS as something that can be attached to the threads, which is the opposite arrangement from the Hersmay: there the shoes are built into the handle, here they are an accessory screwed on
    NATO rails
    Not described. What takes their place is the rod base — the second bullet gives two 15 mm rods with a 60 mm rail spacing, which is the cinema standard for mounting a follow focus, a matte box or a lens support in front of the camera
    Cable clamp
    Not described. As on the Hersmay, the page provides threads and handles and nothing for the strain of an HDMI or USB lead
    Battery and card access
    Not stated. The third bullet describes a built-in 1/4 inch knurled screw allowing the camera to be mounted and removed quickly without tools, which is a partial answer — a cage that comes off in seconds makes a battery change possible without disassembly, even if the door itself is not reachable
    Base profile
    Not described as a tripod plate. The third bullet names silicone padding stabilising the camera against movement and protecting it from scratches, and the base is where the 15 mm rods are carried
    Material
    Aircraft-grade aluminium alloy, CNC machined with an anodised finish, in the fifth bullet
    Published weight
    Not published. The Hersmay beside it gives 230 g; this page gives no figure at all, on a cage that adds two handles and a rod base to a camera
    Amazon reference
    B0722L8J2Y (same reference on 6 Amazon marketplaces)
    EAN
    0191073013513
    • A 15 mm dual-rod base at 60 mm spacing, which is what a follow focus and a matte box mount onto
    • Two ergonomic hand grips and a top silicone handle for low-angle work
    • No published weight, on the heavier-looking of the two cages here

    Best for: A reflex or camcorder rig that needs rods in front — a follow focus, a matte box or a lens support — rather than a cage machined around one body.

Elsewhere in the camera bag

  • HMF ODK100 hard case open showing its pick-and-pluck grid foam

    HMF ODK100, 30.5 by 23 by 14 cm inside, IP67, 1.82 kg

    Forty euros for an IP67 case that publishes everything: 30.5 by 23 by 14 cm inside, split 10.5 and 3.5 between base and lid, three foam layers, 1.82 kg.

    Internal dimensions
    THE MOST COMPLETE FIGURES IN THIS CATALOGUE: 30.5 by 23 by 14 cm inside, and the fifth bullet goes further by splitting the depth — 10.5 cm in the base, 3.5 cm in the lid — inside an exterior of 34 by 29.5 by 15.5 cm measured INCLUDING the handle and catches. The split is what tells you whether a body with a lens fitted stands up in the base
    Ingress rating
    IP67, in the second bullet: dust-tight, and protected against immersion in water to one metre for thirty minutes. It is a standard rather than an adjective, and both cases on this shelf publish it
    Interior type
    THREE LAYERS, itemised in the third bullet: 95 mm of pre-cut grid foam — the pick-and-pluck kind, plucked cube by cube to the shape of the equipment — a 10 mm foam floor beneath it, and CONVOLUTED egg-crate foam in the lid to press down on whatever is below
    Pressure valve
    YES, a pressure-equalisation valve in the fourth bullet. A sealed case carried up a mountain or flown in a hold arrives at a different air pressure from the one it was closed at, and without a valve the lid either jams shut or strains its seal
    Latch and lock provision
    A folding carry handle and EYES FOR PADLOCKS, in the fourth bullet. Padlock eyes are what let a case be checked into a hold or left in a vehicle
    Wheels and handles
    A folding handle, no wheels — correct at this size. Thirty-four centimetres and 1.82 kg is a case that is carried
    Empty weight
    1.82 kg, PUBLISHED in the fifth bullet — the only empty weight on this shelf, and the figure that decides what an airline allowance leaves for the equipment

    B08K3JBWP7 (same reference on 5 Amazon marketplaces)
    EAN
    4010537103422
    • Internal dimensions published with the base and lid depths split out
    • Three foam layers named — pick-and-pluck, floor and convoluted lid
    • No wheels, though at 34 cm none is needed

    Best for: A body, two lenses and a drone taken somewhere wet, dusty or airborne, where the case has to be locked and its weight declared.

  • JJC transparent disposable rain cover over a mirrorless camera and lens

    JJC Two DISPOSABLE covers, 28 by 17 cm, PE film

    Two single-use PE covers for 9 €, 28 by 17 cm, transparent so everything stays visible — emergency protection that lives flat in a bag.

    Lens length accommodated
    Up to 28 cm LONG and 17 cm WIDE, in the first bullet — and the width is the figure nobody else publishes. Length decides whether a telephoto fits; width decides whether a fat zoom or a hood does. Twenty-eight centimetres is the shortest length on this shelf, so this is a cover for a body and a standard lens
    Eyepiece design
    Solved by the material: the whole cover is TRANSPARENT PE FILM, and the third bullet says the viewfinder and the camera controls stay fully visible — no blurred view, no obstruction. A cover you can see through needs no eyepiece opening at all, which is the one advantage of film over fabric
    Hand access
    Through the ends, not through sleeves. It is a sleeve of film with drawcords, so the hands go in where the cords are
    Material and seams
    Lightweight transparent PE film, in the third bullet, described as ultra-thin and easy to carry. No seam treatment is described — and on a single-use cover that matters less, since it is discarded before it can fail
    Closure method
    ADJUSTABLE DRAWCORDS, in the fourth bullet, fitted quickly over the lens with no complicated assembly and pulled tight to stop water entering during a long outdoor session
    Packed size
    Not given as a figure, but the third bullet is explicit about the property: ultra-thin and light, easy to carry in a camera bag. A disposable film cover folds to the size of a handkerchief, which is why two of them can live permanently in a bag pocket

    EAN
    6950291530974
    • Transparent throughout, so viewfinder and controls stay visible
    • Both length AND width published — 28 by 17 cm
    • Disposable: two uses, then they are gone

    Best for: Emergency rain that was not forecast, on a body and a standard zoom, from a cover that has been in the bag since the day it was bought.

  • JZK rain cover fitted over a reflex camera with its clear rear panel visible

    JZK 32 cm of lens, full-length zip, no flash space

    Nine euros for a cover taking 32 cm of camera and lens, with a full-length zip and a clear rear panel — and a title that admits there is no room for a flash.

    Lens length accommodated
    32 cm for camera AND lens together, in the first and second bullets — the second-longest on this shelf behind the 39 cm K&F. Thirty-two centimetres takes a reflex with a 70-200 mm zoom; it does not take a 400 mm. The figure is published twice, which on this shelf counts as emphasis
    Eyepiece design
    Not described. Nothing on the page says how the eye reaches the viewfinder — an eyepiece opening, a drawcord, a transparent panel — which on a reflex is how the picture gets composed
    Hand access
    Not described either. The fourth bullet covers the zip and the fifth the screen window, and neither says how a hand reaches the controls
    Material and seams
    Waterproof and dustproof, in the third bullet, usable in the rainy season, in the desert and at the beach. No fabric is named and no seam treatment described — and on a rain cover the seams are where water arrives first
    Closure method
    A FULL-LENGTH ZIP, in the fourth bullet, allowing the cover to be closed from underneath whether the camera is hand-held or on a tripod, without weakening the rain protection. A zip that runs the whole length is what lets the cover go on around a mounted camera rather than over it
    Packed size
    NOT PUBLISHED, as on four of the five covers here. A cover that does not fold small is a cover left at home
    Amazon reference
    B01MS6E4JX (same reference on 6 Amazon marketplaces)
    EAN
    6920484230592
    • Thirty-two centimetres of camera and lens, published twice
    • A full-length zip that closes from below, on a tripod or in the hand
    • The title states there is no space for a flash

    Best for: A reflex with a mid-length zoom in real rain, used on a tripod where the cover has to close underneath.
