Canon PowerShot G1 X: What It Is, and Whether It Still Makes Sense

The Canon PowerShot G1 X was Canon's attempt to put a camera sensor the size of a DSLR's into something you could carry in a coat pocket. It ran for three models across five years, and it is now over: Canon's own UK store lists the final model as discontinued and permanently unavailable.

This is not a review. Nobody at TechOrbitly has held a G1 X, so you will not find opinions here about how it feels in the hand or how its files look at ISO 6400. What follows is what the three cameras actually were, taken from Canon's published specifications, why the line ended, and a way of deciding whether a used one is worth your money — which is the only way to buy one now.

What the Canon G1 X actually is

Compact cameras traditionally used tiny sensors. That is the reason phone-sized cameras produced phone-sized image quality: a small sensor collects less light, which costs you detail in dim rooms and the shallow-focus look that makes a portrait stand out from its background.

The G1 X was Canon's answer. When it launched in March 2012, Canon described a sensor "approximately 6.3 times larger than the 1/1.7-inch sensor employed in the G1 X's predecessor, the PowerShot G12", with "a height dimension comparable to that of APS-C size sensors". In other words: most of the light-gathering advantage of a proper interchangeable-lens camera, in a body with a fixed zoom lens and nothing to swap.

That is the whole premise of the line, and it is why the G1 X was always expensive relative to other compacts. You were paying for sensor area.

The three models, and which one you are looking at

The name is used loosely, and the three cameras are genuinely different. If you are shopping, this is the section that matters.

Canon PowerShot G1 X Mark III

Marketed November 2017, and the last of the line. Canon calls it "Canon's first compact camera to utilize an APS-C sized CMOS sensor with 24.2 million effective pixels", paired with the DIGIC 7 processor.

From Canon's specification sheet:

Canon also notes it is "a weight reduction of approximately 27% and an approximately 16% reduction in body size compared to its predecessor".

Canon PowerShot G1 X Mark II

Marketed March 2014. This one keeps the 1.5-inch sensor of the original rather than moving to APS-C — Canon describes "a large Canon-developed 1.5-inch CMOS sensor" with "total pixel count: approx. 15 megapixels, effective pixels: approx. 12.8 megapixels (3:2)".

Here is the part people get wrong. The Mark II has the better lens: "a fast f/2.0-f/3.9 lens with 24-120 mm (35 mm film equivalent) 5x optical zoom". That is a full stop and a half faster at the wide end than the Mark III, and it reaches considerably further. It is also the heavier camera at approximately 553 g against the Mark III's 399 g, in a chunkier body of roughly 116.3 x 74 x 66.2 mm.

So the Mark III is not simply a better Mark II. Canon traded lens speed and zoom range for sensor size, autofocus and portability. Which of those you want is a real question, not a foregone conclusion.

The original PowerShot G1 X

Marketed March 2012. A 1.5-inch sensor of approximately 14.3 megapixels, the DIGIC 5 processor, and a "4x optical zoom lens (28-112 mm / f/2.8-f/5.8)". It shoots 14-bit RAW — Canon points out it "supports the same 14-bit RAW shooting as Canon's EOS series of digital SLR cameras" — and it accepts Speedlite flash units.

It is a fourteen-year-old camera. Everything about handling and autofocus has moved on since, and only the sensor size still argues for it.

Why it was discontinued, and what replaced it

Nothing replaced it. There is no G1 X Mark IV, and Canon has not announced one. The Mark III was marketed in November 2017 and the line stopped there.

The discontinuation is not a rumour: Canon's own UK store page for the Mark III carries the words "Discontinued" and "Permanently unavailable".

Canon has not published a reason, and it is worth being honest that the usual explanation — that phone cameras absorbed this market — is an inference rather than something Canon has said. What can be stated from the record is the shape of it: Canon's compact range shrank considerably over the same years that its mirrorless range expanded, and a premium fixed-lens compact sat awkwardly in price against an entry-level interchangeable-lens body.

If you want a current Canon with the same sensor size, the answer is an interchangeable-lens camera, not a compact.

Should you still buy one in 2026?

Only a used one exists, so this is a used-camera decision, and the honest framing is a set of checks rather than a recommendation.

The case for it. Sensor size has not been superseded by anything. An APS-C sensor in 2017 gathers the same light as an APS-C sensor today, and that is the one specification that does not age. If what you want is a single pocketable camera that produces noticeably better images than a phone in poor light, a G1 X still does the thing it was built to do.

The case against it. Autofocus, video and connectivity have all moved on sharply. The Mark III tops out at Full HD — if you want 4K, this is the wrong camera and no firmware will change that. Battery life of approximately 200 shots is modest, and you will want a spare. And a used body of this age carries the usual risks: a worn shutter, a tired battery, a lens mechanism that has been in a pocket for eight years.

What to check before buying. Ask the seller to power it on and zoom through the full range while you watch, since lens mechanism faults are the common failure on compacts of this era. Check that the screen articulates freely and that the touch panel responds across its whole surface. Confirm the battery is a genuine NB-13L and ask how long it holds a charge. Take a photograph at the widest and longest ends and look at the corners. And confirm the card door and battery door close firmly — the dust and drip resistance Canon claims depends on it, and Canon says explicitly that you should "keep the terminal cover, memory card/battery cover, and all other covers firmly closed".

Are compact cameras dead? Not as a category, but as a mainstream one, largely yes. What survives is exactly the niche the G1 X occupied: cameras bought deliberately by people who want something a phone cannot do, rather than bought by default.

How it compares

Against the PowerShot G7 X, the trade is sensor against lens and price. The G7 X line uses a smaller 1-inch sensor but is cheaper and slimmer, and it stayed in production far longer.

Against the Sony RX100 series, the same logic applies and the RX100 line went through many more generations, so a similarly-priced used RX100 may simply be newer.

Against a smartphone, the G1 X wins on sensor area and optical zoom and loses on everything else: computational processing, sharing, updates, and the fact that your phone is already in your pocket. That is the honest comparison, and it is why this class of camera contracted.

Against an entry-level mirrorless body, the G1 X Mark III's advantage is that it is one sealed object with no lens to carry. Its disadvantage is that you can never improve it.

Living with one: the things owners actually search for

Canon still hosts support material for all three models, which is the practical good news for owners.

Battery, charger and power

The Mark III uses the NB-13L rechargeable lithium-ion battery, supplied with a charger. Canon rates it at approximately 200 shots per charge, or approximately 250 in Eco mode. Both figures are lab ratings; heavy use of the EVF and Wi-Fi will land you below them. If a camera will not power on at all, the battery is the first thing to eliminate — these cells are now many years old, and a battery that charges but drops dead under load is the most common symptom.

Firmware, manuals and support

Canon's support site still carries manuals, software and firmware downloads for the G-series, including the G1 X models. If you have bought a used body, downloading the manual for your specific model is worth doing before anything else — the three cameras differ enough that generic advice will mislead you.

Cards, Wi-Fi and getting pictures off

The Mark III takes SD, SDHC and SDXC cards and is UHS Speed Class 1 compatible. A faster card will not hurt but will not help much either.

For wireless, the Mark III has Wi-Fi (IEEE 802.11b/g/n, 2.4 GHz only), Bluetooth low energy, and NFC support. Pairing is handled through Canon's Camera Connect app. Note the 2.4 GHz restriction: if your phone is on a 5 GHz-only network, connection problems usually trace back to that rather than to the camera.

When something goes wrong

A lens error on a compact of this age usually means the zoom mechanism has been obstructed or knocked. It is a hardware fault, not a settings problem, and it is the single most important thing to test before handing over money for a used body.

If the screen appears dead, check the display toggle before assuming failure — the Mark III can route the image to the electronic viewfinder instead, and a camera set to EVF with a blank rear screen looks broken and is not.

A full settings reset is available in the camera menu and is worth trying before concluding that anything is wrong, particularly on a second-hand body that arrives configured by its previous owner.

Settings worth knowing

The Mark III offers the full set of exposure modes: Program AE, Shutter priority AE, Aperture priority AE and Manual, plus two custom slots. Aperture priority is the mode that makes the most of this camera, because the entire point of the large sensor is control over depth of field.

Shoot RAW if you intend to edit. All three cameras record 14-bit RAW, which gives far more latitude to recover a bright sky or lift a shadow than a JPEG will. Canon's Digital Photo Professional handles the files.

The Mark III also includes a time-lapse movie mode and star modes for night scenes, both of which are built into the scene menu rather than requiring an accessory.

The short version

The Canon PowerShot G1 X was a good idea executed three times, and it is finished. The Mark III is the one most people mean, and it remains the only Canon compact with an APS-C sensor. If you want one, you are buying used, you are buying Full HD video rather than 4K, and you are buying a camera whose sensor has aged well and whose electronics have not.

That is a reasonable purchase for someone who knows exactly why they want it. It is a poor default.
