Still, it would have been nice to have a couple hundred more mAh. Flash: Surprisingly useful, though not powerful. The GN of 7. My measurements say it doesn't quite achieve that, but it's not far off. You're at a level where adding flash will make a meaningful difference in most situations you'd try to use it for fill. Nikon definitely raised the bar for mirrorless camera focus performance, and that was clearly evident to me using the two side by side.
Not quite as snappy as the V1, but close enough to make it a race. It's when subjects start moving that things change. It's actually not that the focus system doesn't respond quickly on the GX1, it's that it doesn't track solidly. The faster or more disjointed the subject motion is, the more you see the focus system undershoot or overshoot where it should be, then struggle to catch up. This has long been the Achille's heel of contrast-based focus systems, so it isn't a problem unique to the GX1.
I tried to find a difference in tracking between the G3 and GX1. I couldn't reliably come up with anything that indicated to me that the GX1 was consistently and measurably better, but anecdotally it felt there were times when it did indeed hold track a bit better than the G3.
Some of my disappointment is that in the first generation of mirrorless, Panasonic was at the forefront of focus performance. I would tend to characterize the GH1 with mm lens performance as state of the art for contrast focus at the time of its introduction. Part of that was the video refresh speed of the sensor, part was the type of motors used in the Panasonic lenses.
Both were a step forward for contrast focus. Unfortunately, I can't really say that a lot has changed two generations later: initial acquisition is still reasonably fast, follow focus works on slower motion though with occasional hunts , and birds in flight are near impossible, especially for continuous shooting. In other words, no pragmatic progress even though we've had some modest overall improvement. I can't reliably shoot things now that I couldn't shoot before, though I do get a few more keepers overall.
Image Quality: Let's get the good news out of the way first: if you like detail, the GX1 very well may deliver what you want. It seems to have a lax anti-aliasing filter, because I'm seeing clear false detail above the Nyquist frequency in raw files.
It resolves slightly above its class. On the other hand, in JPEGs some of that "detail" isn't detail at all, but over aggressive sharpening. Interestingly, noise seems to play into the resolution appearance on the GX1.
Panasonic has finally played down the color noise while letting luminance noise stay. Some people will like that. Unfortunately, it makes for a slightly grainy appearance, even at low ISO levels. That said, there is a slight improvement over the G3, which uses the same sensor. You can clearly see this at ISO , where the balance of detail destruction and noise is better handled on the GX1 than the G3. But it's present at all ISOs to a smaller degree.
Curiously, most of that difference appears to be in the green channel, not the red and blue channels. When examining the raw files shot at the same time, I can't find any differences in the G3 and GX1 ones that can't be attributed to very small sample or testing variations. The interesting thing is that I don't see a big falloff in the sensor's capability in raw files until I get to ISO That's not good for JPEG shooters, at least.
The small built-in flash lifts up from the front of the viewfinder housing. Most notably, Canon has finally included an auto-stitching sweep-panorama mode. You can choose the direction you wish to move the camera, and generate files up to x or x pixels, depending on which way round you hold the camera.
Results are impressive, being highly detailed with no hint of stitching errors. This means that if you point it towards the sun at any point, that section will get overexposed. In this particular respect, most modern smartphones do much better. When it comes to video, Canon has again disappointed any fans hoping that it might finally include 4K recording in an affordable camera.
One consolation is that in-camera time-lapse movie creation is available. Unfortunately, it offers little user control; the camera just takes one shot every 3 seconds for 15 minutes and then compiles it into a movie. This makes it easy to connect the camera wirelessly to a smartphone, tablet, printer or smart TV for copying, printing or viewing your shots.
Connections are set up using a small button at the base of the handgrip, which also provides a simple way to push images across to your phone when browsing through them in playback.
The camera forms an always-on connection to your phone, allowing you to use your phone as a basic wireless remote control at any time via the Canon Camera Remote app. The SLR-styled body layout is lifted from the 1in-sensor G5 X, which is no bad thing as that camera is very pleasant to shoot with. Indeed, I used it in snow showers with no ill-effects.
The central EVF affords a very natural balance, while giving a decent amount of space on the body for buttons and dials. At Yet despite its petite size, the camera feels unexpectedly secure in your hand, thanks to its good-sized rubberised fingergrip and pronounced thumb hook.
Canon has included an EOS-like electronic dial for changing exposure settings. It sits vertically on the front-plate for operation by your forefinger, along with an exposure compensation dial that falls beneath your thumb.
The exposure mode dial is another awkward one, as you have to hold down a button in its centre to be able to turn it, which turns out to be a lot less easy compared to the larger dials on EOS DSLRs. A toggle-type lock would have worked better here. The small exposure mode dial has a lock button to prevent accidental movement.
A rocker around the shutter button controls the zoom, but you can use the dial around the lens, too, which I found offers much finer control over composition. This dial rotates smoothly with no clicks, and can be used for manual focus as well.
Doing so would have provided the option of using the lens dial as a large and tactile control for changing exposure settings. These are all rather small and crowded together, however, and some users might find it too easy to press the wrong one by accident.
You get a decent degree of control customisation, too. For example, the AE-L button can be used for back-button focus, the video and AF-area selection buttons can be reassigned to other functions, and the three electronic dials can be configured separately for each exposure mode. Overall, the physical control layout works rather well, and I even found it quite usable shooting in the cold with my thin, but snug MacWet gloves.
The corresponding values for the Canon G1 X are Since , DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. Of the two cameras under review, the G1X has a notably higher overall DXO score than the GX1 overall score 5 points higher , which gives it an advantage in terms of imaging quality.
This advantage is based on 0. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators. Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX1 provides a faster frame rate than the G1X. Apart from body and sensor, cameras can and do differ across a variety of features.
For example, the G1X has an optical viewfinder , which can be very useful when shooting in bright sunlight. The table below summarizes some of the other core capabilities of the Canon G1 X and Panasonic GX1 in connection with corresponding information for a sample of similar cameras.
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The GX1 has a touchscreen , while the G1X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process.
The table below provides an overview of the connectivity of the Canon PowerShot G1 X and Panasonic Lumix DMC-GX1 and, in particular, the interfaces the cameras and selected comparators provide for accessory control and data transfer.
Further information on the two cameras e. So what is the bottom line? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants. If the count of individual advantages bullet points above is taken as a guide, the GX1 comes out slightly ahead of the G1X 8 : 7 points. Hand-holding the GX1 during movie recording inevitably leads to obvious shake, despite the optical image stabilizer on compatible lenses, so for best results you'll need a dedicated video tripod.
One great benefit of the touch-screen control system is that Touch Auto Focusing is available in movie recording, enabling pro-level rack-like focusing simply by pointing at the subject on the LCD screen.
You can also use features like Photo Styles, metering modes, Intelligent Resolution and Intelligent Dynamic Range for video as well as stills. Panasonic have published marketing data which suggests that the GX1's AF is as fast, if not faster, than a typical DSLR camera's, with a claimed speed of just 0. In practice we noticed very little difference in speed between the GX1 and a DSLR, and there were also very few occasions when the GX1 failed to lock onto the subject, especially when using the centre AF point.
It takes about 1 second to store a JPEG image, allowing you to keep shooting as they are being recorded onto the memory card - there is a barely perceptible LCD blackout between each image. Storing a single RAW image takes around 4 seconds, but thankfully it doesn't lock up the camera in any way - you can use the menu system or shoot another image while the first file is being written to memory. There's also a faster 20fps mode, but the images are only recorded at 4 megapixels.
Once you have captured a photo, the Panasonic Lumix DMC-GX1 has an average range of options when it comes to playing, reviewing and managing your images. You can instantly scroll through the images that you have taken, view thumbnails up to 30 onscreen at the same time and in a Calendar view , zoom in and out up to 16x magnification, view slideshows, delete, protect, trim, resize, copy and rotate an image. You can also select favourite images, change an image's aspect ratio, divide a video and set the print order.
You can also turn on guide-lines to help with composition and flashing highlights which indicate any over-exposed areas of the image. Now let's take a look at its image quality on the next page All of the sample images in this Review were taken using the 16 megapixel Fine JPEG setting, which gives an average image size of around 6Mb.
ISO exhibits quite visible noise and loss of fine detail, and the fastest settings of ISO and are even noisier but still usable for small prints and web use. The images were a little soft straight out of the camera at the default sharpening level and ideally require further sharpening in an application like Adobe Photoshop, or you can change the in-camera setting if you don't like the default results.
The pop-up flash worked well indoors, with no red-eye and good overall exposure. The night photograph was excellent, with the maximum shutter speed of 60 seconds allowing you to capture plenty of light. There are some subtle differences between the Intelligent Resolution settings, and Intelligent D-range is an effective feature for capturing more detail in the shadows and highlights. The right-hand image has had some sharpening applied in Photoshop.
The out-of-the camera images are a little soft at the default sharpening setting, and benefit from further sharpening in a program like Adobe Photoshop. You can also change the in-camera sharpening level by tweaking the Film Mode, with five different settings available. These shots of a white coloured wall were taken at a distance of 1. And here are some portrait shots. As you can see, neither the Flash On setting or the Red-Eye Reduction option caused any amount of red-eye.
The Panasonic Lumix DMC-GX1 maximum shutter speed is 60 seconds and there's also a Bulb option for exposures up to 4 minutes long, which is excellent news if you're seriously interested in night photography.
The shot below was taken using a shutter speed of 15 seconds at ISO The camera takes the same amount of time again to apply noise reduction, so for example at the 15 second setting the actual exposure takes 30 seconds. The Panasonic Lumix DMC-GX1's mm kit lens has a built-in shake reduction mechanism, which allows you to take sharp photos at slower shutter speeds than other digital cameras. To test this, I took 2 handheld shots of the same subject with the same settings.
The first shot was taken with anti shake turned off, the second with it turned on. The Panasonic Lumix DMC-GX1's Intelligent Resolution feature identifies outlines, texture areas and soft gradation areas of the image and then automatically optimizes the edges and detailed texture areas while using noise reduction to make the soft gradation areas smoother.
There are three available strengths - low, standard and high. The Panasonic Lumix DMC-GX1's Intelligent D-range feature adjusts the exposure setting to record more detail in the highlights and shadows, with three strengths available - low, standard and high.
Panasonic's Photo Styles, similar to Nikon's Picture Styles, Canon's Picture Controls and Olympus' Picture Modes, are preset combinations of different sharpness, contrast, saturation and noise reduction settings.
The six available Photo Styles are shown below in the following series, which demonstrates the differences. There is also a Custom option so that you can create your own look.
The Panasonic GX1 has a range of Creative Controls, denoted by an artist's palette in the shooting mode menu, with 8 different options on offer. The thumbnails below link to the full-sized versions, which have not been altered in any way. Download Original.
