I like
Canon surprised many observers and photographers launching the Powershot G1 X, a new kind of device in the range of Canon digital compact, untouched offer “hybrid” because it is not equipped with a holder for the lens to change, it has, however, a large sensor in 4:3 format to be six times larger than that of the G12 and a size slightly larger than that of the sensors of compact hybrid Panasonic Lumix G or Olympus Pen and OM-D.

CMOS technology, technology that has proven itself on the S100, for example (see the test of Canon Powershot S100), called “HS” for high-sensitivity CMOS sensor 14 megapixel Canon G1 X may peak at 12,800 ISO. For an audience of photographers’ amateur-experts, the G1 X allows saving photos in RAW format quality and powerful in terms of freedom of post-treatment with a 14-bit sampling for image quality worthy of final that of a reflex on the paper.

Ergonomics: G1 G12 X inherits

It borders on flawless: Canon G1 X inherits the proven ergonomics G1, G2, G3 …. G12, itself inspired by the Canon EOS digital SLRs. Double game wheel, wheels steel knurled for selecting the shooting mode and exposure compensation, etc.. Only two regrets: the removal of the ring sensitivity setting and the absence of a manual zoom ring, what a pity that the lens barrel has plenty of room and does not penetrate inside the box when you turn off the G1 X.

Optical Viewfinder: an appearance

We will quickly on the optical viewfinder which has the merit to exist. This will be his only quality. It is as bad as the G12: narrow, sketchy, brief, unpleasant to use. Damage. An optical viewfinder is more important for a camera expert (see the test Fujifilm X-Pro1), but the G1 X, we can live without …
We appreciate all the more beautiful screen 3 “/ 921 000 pixels, like the G12, is articulated.

Congestion Canon G1 X

The G1 X is very attractive with its large sensor and ergonomics worked, but the price is quite high: the weight and size swell.
– Weight: The G1 X still weighs 534 grams, 133 grams more than the G12 already quite heavy for a compact.
– Dimensions: G1 X is 1.64 cm thicker and almost half a centimeter taller and wider than the G12.
Finally, the G1 X fits easily into a pocket of big winter jacket. Exclude slip into the pocket of your pants or shirt. It is also really heavy. We strongly advise potential buyers of the G1 X to weigh before you buy. It seems slightly more bulky than the G12 on the visuals, but in practice, its space can be a greater handicap than it seems. It will naturally an advantage in terms of compactness and weight when compared to a DSLR.

4x stabilized zoom lens

The lens of the G1 X, an amplitude of only 4x zoom range to little current (28-112 mm) is very ambitious in terms of focal lengths as to what is the correct opening is wide-angle (f/2.8), but only f/5.8 at 112mm. It is stabilized by the optical device Canon IS.
You may want to buy a camera with a large sensor to exploit its ability to generate a bokeh effect, but on this point, the small lens aperture telephoto left us on our hunger. It restores depth of field still important, typical of a conventional digital compact. Canon is missed.
Its closest focus often asked to switch to macro mode for close-up pictures.
A good, apart from its high sharpness, the lens includes a filter density gray 3EV that can be activated to lower the exposure speed maintaining a large opening or for example to more easily create an effect of yarn.

General responsiveness, autofocus

Despite the presence of a powerful processor on paper (DIGIC 5) Canon Powershot G1 X is struggling to provide the responsiveness that we are entitled to expect from a premium compact market in 2012. The G1 X is slow, its autofocus is really poor and RAW + JPEG images are recorded on the memory card is now a senator. Today, more is expected of a compact camera: the Panasonic GF5 amateur small hybrid will focus in just 0.09 s and even a classic like the Sony compact HX20V (a 25-1000mm) is capable of putting developed in 0.13 s. In short, the G1 X is built for action photography, far from it … but even in the context of typical daily use, the phlegm becomes annoying over time and to miss many opportunities photo on the spot.

Canon G1 X offers an HDR mode by stacking three photos taken at different exposures which is significant compared to models that simply underexpose a single picture and to enhance low and mid tones by software. Unfortunately hit by a burst shooting indolent, without a tripod, the pictures are too far apart and it will be impossible G1 X align perfectly. We have failed any test HDR freehand …

Providing comfort and freedom in framing the articulated screen is appreciable.

Image Quality: Canon Powershot G1 X vs. Powershot G12

It is actually much bulkier and heavier than the G12, its sensor is larger and it is his main argument, which is the image quality. Its sensor measuring 18.7 x 14 mm to 14 megapixels that when the G12 is only 7.5 x 5.6 mm to 10 megapixels. The pixel pitch of 2.03 microns thus passes on the G12 to 4.16 microns on the G1 X. This results in a much higher level of performance. The test DxO Analyzer, the overall score (or DxOMark Score), password
– 47 points for the G12
– 60 points for the G1 X
Not surprisingly, it is the sensitivity that benefited most from large sensor: measured in low light at ISO 161 lePowershot G12, it culminates on the Powershot G1 X ISO to 644 or 2 stop difference.

Unfortunately, the dynamic range of the new sensor G1 X does not benefit the progress of this new generation. It is even slightly from 11.2 EV of the Canon G12 only 10.8 EV of the Canon G1 X. The maximum dynamic range is really the Achilles heel of sensors Canon earn more dynamic below ISO 200. But the G1 X retains an advantage over the G12 when it exceeds 100 ISO, the hierarchy is then reversed and the G1 X shines with its dynamic stability. At ISO 400, the G1 X is 2EV more forgiving than G12.
Regarding the color depth, the G1 X sensor has a sampling 14-bit, 12-bit against the G12, where a score slightly.
The signal / noise ratio of the G1 X compared to the G12.


The dynamics of the G1 X sensor is progressing more below ISO 200.

Two diaphragms with a sensitivity higher than the G12 and dynamics, equivalent to ISO 100, but better after ISO 200, 14-megapixel CMOS sensor G1 X completely justifies the excess overweight device.

Canon Powershot G1 X vs Panasonic G3 vs Sony NEX-5N

Given its size and price, many of you will hesitate between buying a Canon G1 X and that of a compact hybrid. Moreover, the sensor is a compromise between the APN and the Micro 4:3 APS-C as the Sony NEX.
A reading of the results, we see that the logic of the size of sensitive surfaces is fully respected: the G1 X with its DxO score of 60, ahead of the Panasonic G3 and 56 points (but with only 4 points gap) and is quite frankly distanced by the famous APS-C 16-megapixel CMOS Sony NEX-5N, which also equips the Nikon D7000 or the Pentax K-5, with a score of 77 points.
Sensitivity Panaosnic G3 and Canon G1 X are equivalent, although one could expect a benefit in favor of Canon. As for the NEX-5N sensor remarkable high sensitivity, it is more sensitive than 2/3EV his two challengers. The APS-C is beneficial in this regard. The hierarchy is reproduced identically in terms of dynamics.
Sensor with a newer design as that fitted the Lumix G since their launch, without much progress, CMOS Canon G1 X is not much better, despite his youth and a sensitive surface slightly larger . The APS-C size (especially with Sony sensor) allows SLR and compact hybrids feature, keep a significant advance.

Canon Powershot G1 X vs Canon EOS 7D

And compared to a sensor Canon EOS G1 X which will often be chosen lining more portable, how does the sensor Powershot G1 X? All current Canon DSLRs not full frame, with the exception of the EOS 1100D (EOS 600D therefore, EOS 60D and EOS 7D), are equipped with the same APS-C CMOS imager 18 megapixel definition. Faced with the EOS 7D, the G1 X is not really favored by the modern design of a CMOS sensor. Its performance is slightly lower compared to the 18 megapixel sensor EOS SLR. Its lead in the G1 X sensor is again proportional to its extra few mm2. The G1 X offers good image quality worthy of a DSLR, in any case, of the same class, because it will slightly recessed, so fine, but the tangible DxO test: the Canon G1 X 1/3 EV less efficient in low-light sensitivity as the EOS 7D and a wide dynamic diaph less.



Image Quality – Field Test of the Canon G1 X

Sensitivity: the contribution of large sensor

In this assembly views to 100% detail of a photograph taken in Canon Powershot G1 X, we note that the picture quality is very consistent from 400 to 1600 ISO (spend the first 2 pictures that are in fact AF blurry …. thank you …). The large sensor and healthy G1 X ally noise processing Canon signed and a powerful processor, can be used without complex G1 X until 1600. There is only from ISO 3200 as light whitecaps appear. But even at ISO 6400 and 12800, the image is exploitable. This is remarkable.

If you are interested in the G1 X, you love beautiful cameras and should definitely consider also the case with the Fujifilm X10 sensor 2/3 “. Comparative Here is the same picture taken with the X10:


Image quality – the best in its class

If it is so cumbersome is that the Canon G1 X large sensor offers a couple – quality objective. The compromise was achieved at the expense of the size of the device and reap the benefits in the image: the G1 X offers a quality SLR with a very detailed picture for low sensitivity to a level which is exceptional in a compact high ISO. Its white balance is apart from the competition by his insight, even in harsh environments. By cons, automated intelligent exposure are conspicuously absent and cons when days are legions of other compact compensate themselves exposure when they detect a strong light source behind the subject.
Apart from this point, in terms of image quality, the Canon G1 X is a success.
Testing the Canon Powershot G1 X: Conclusion

699 euros is the price to pay to provide Powershot G1 X. It is the price of a reflex as leCanon advanced EOS 600D which will provide a more responsive autofocus, a true reflex viewfinder, shooting burst less modest, less simplistic video mode and picture quality slightly higher with 1 / 3V sensitivity and a more dynamic diaph further, but at the cost of other dimensions. However, the Canon G1 X does not shine by its compactness or lightness. But with a DSLR …
The target of the G1 X is clearly the expert photographer already equipped with a digital SLR like the EOS 7D or EOS 5D Mark III and would like a lining more discreet and portable without sacrificing ergonomics and quality of image. As such, the Canon Powershot G1 X fulfills this function.
But, apart from its uncompromising image quality and ergonomics accomplished, the PowerShot G1 X combines the disadvantages: slow autofocus, poor viewfinder, aim low amplitude and low light … that irritate the long and cost him the title of dream device for expert amateur photographer. But in its class digital compact with a large sensor, the Canon G1 X is alone.

The G1 X 28mm ….
… and to 112mm. We would go a little deeper into the image.
44mm – f / 5,6 – 1/30s
A 1/30s, the picture remains clear thanks to the Canon IS.
For cons, the G1 X has been abused by the blackness of the water and we had to compensate the exposure here-1EV.


At ISO 100 – f / 5.8 – 1/250s
At ISO 100, with a minimum aperture, the photo is full of details.


Here is an example of HDR failed, however, in broad daylight, because taken freehand.


ISO 100 – f / 5,6 – 1/100s at 41mm.
ISO 160 – f / 7,1 – 1/1250s to 57mm. In auto mode, the G1 X was “dazzled” and the slightly underexposed status.
ISO 200 – f / 5,6 – 1/1000s – 37mm.


ISO 160 – f / 6,3 – 1/1250s
ISO 100 – f / 5.8 – 1/800s – 19mm
Another HDR failed …. damage the subject lent itself.
