Review based on a production DMC-G3, Firmware version 1.0
The G3 heralds the start of Panasonic's third generation of mirrorless cameras. In some respects it's a refinement of previous models; its electronic viewfinder and hinged rear display screen are identical to the G1 and G2, for example. However, behind the aluminium front panel of its slimmed-down, externally-simplified body lies a completely new 16.7MP sensor. This makes it the first mass-market Micro Four Thirds model to move beyond Panasonic's 12MP chip.
While some of the new features of the G3 suggest a move upmarket, many other changes point to an attempt on Panasonic's part to make the G-series more accessible. A number of features have been removed, presumably in order to make this model both less intimidating and less expensive (the recommended price is $100 lower than the launch price of the G2).
Mirrorless interchangeable lens cameras are still relatively new. As such, manufacturers are still trying to determine their target audience as well as the balance of features, capabilities and pricing that will have the widest appeal. Panasonic's Lumix DMC-G1, released back in 2008, was essentially a miniaturized version of the company's L10 DSLR, sharing similar features and appearance. More recently, however, mirrorless camera designs are looking to capitalize on the differences the technology can offer, such as compact size and seamless video integration, rather than trying to mimic conventional DSLRs.
The compact-camera-like hand grip is the first, most obvious evidence that the G3 fits into this philosophy. Gone is the prominent lump that has become standard for DSLRs, and instead we have a grip that more closely resembles that of the GF2 - a low profile rounded extension that encourages a very different hand position on the camera. In fact, the G3 is as close in size and appearance to a Panasonic Lumix DMC-GF2 (with a viewfinder) as it is to the Panasonic Lumix DMC-G2.
From the GF2, the G3 gains a touchscreen interface that is a vast improvement over that seen in the G2. It allows lots of control over camera settings as well as direct on-screen selection of the focus point - something that no DSLR can offer. Further distancing itself from previous G-series models, the G3 allows you to place the AF point anywhere throughout the entire frame, as opposed to just within a central portion.
The G3 also gains improved video capability, matching the GF2's ability to output either 1080i60 or 720p60 (both from 30fps sensor output). And, while this isn't up to the same specification as the video capability of the Panasonic Lumix DMC-GH2, the G3 does gain that camera's image processor and impressive autofocus speed.
Beyond this, the bulk of the G3's new features are incremental improvements - there's a picture-in-picture manual focus magnification option so that you can focus while still viewing the overall composition, and a Pinpoint AF mode that combines a small AF area with a zoomed preview for precise focusing. The G3 also features subject-tracking AF while shooting video.
Regrettably however, much has been removed from the new model, too. Unlike the G2, the G3 doesn't have an eye sensor for its viewfinder, so you'll have to manually switch between it and the rear display screen. It also loses the G2's focus point dial and focus mode lever, along with the option for connecting an external microphone (thus ensuring that it doesn't tread on the GH2's toes).
Taken as a whole, these changes lead us to suspect that the G3 might replace both the G2 and the lower-spec'd G10 in Panasonic's lineup. It's worth noting that its suggested price also sits exactly mid-way between those two models.
Panasonic G3 specification highlights:
- 16.7MP CMOS sensor (standard Micro Four Thirds size)
- ISO 160-6400
- 4 fps continuous shooting (20fps at 4MP)
- GF2-style touch screen interface
- 1080i60 AVCHD shooting (from 30p sensor output)
- All-area AF point selection
- Pinpoint AF mode (magnifies focus point to allow confirmation and fine-tune of AF position)
- Tracking AF in video mode
- Picture-in-picture manual focus magnification
- 460k dot articulated LCD
- 1.44M dot-equivalent electronic viewfinder (phase sequential type)
Size compared to a typical DSLR

| Placed next to the Rebel T3i / 600D - fairly typical in size for an entry-level DLSR - the size difference of the G3 becomes immediately apparent. |

| A top-down view further emphasizes the distinction; the G3 is considerably smaller in every dimension. Even at this size, however, the G3 is not going to fit in a pocket. |
Casio Europe has released the Exilim EX-ZS15, a touch-screen compact with a 5x wide-angle zoom. The 14MP CCD-based camera features a 26-130mm equivalent lens and 3" touch-sensitive display. The touch-screen display not only includes a touch-shutter mode but also replaces virtually all the camera's buttons, leaving just a shutter, video record, Best Shot Selector and power buttons. Beyond this the camera can shoot 720p30 video.
Just Posted: Our AF-S Nikkor 50mm f/1.8 G sample gallery. We've had access to Nikon's latest inexpensive 50mm prime lens for a couple of weeks and have put together a 41-image sample gallery to show some of what it can do. The AF-S G version means there's finally an inexpensive Nikon 50mm lens that will autofocus on the company's entry-level bodies, such as the D40, D60, D3100 and D5100. Here we've shot it using both the DX D7000 and the FX D3S to show how it performs on both formats.
Pentax has announced a special edition of its 645D 40MP medium format camera to celebrate being named 'Camera of the Year' at the Camera Grand Prix Japan 2011. The built-to-order special comes with a red lacquer finish and special camera strap, arranged in a paulownia-wood box. The company has not announced how many it will produce. Pentax previously made a special edition of its K10D DSLR when it received the equivalent award in 2007.
Alongside its three PEN bodies, Olympus has announced the M. Zuiko Digital ED 12mm F2.0 and M. Zuiko Digital ED 45mm F1.8 prime lenses for Micro Four Thirds. The 12mm F2.0 is a metal-bodied 24mm equivalent featuring a unique snap-focus manual focus mode. A snap-back focus ring reveals a traditional depth-of-field scale for 'zone' focusing and offers improved focus 'feel.' Later in the year it will be accompanied by the 45mm F1.8 portrait lens, making Olympus one of the only manufacturers to offer a fast prime at a roughly 100mm equivalent focal length, ideally suited to portraiture. There is also a relatively compact, bouncable and remotely commandable flash, the FL-300R, helping the PEN range look more like a complete system. More details of the 12mm F2.0 are included in our E-P3 preview, along with a gallery of sample images.
Sigma has announced pricing and availability for its 105mm F2.8 EX DG OS HSM Macro lens. The optically stabilized version of the lens, originally announced back in February, is available now with a recommended selling price of $1,400. The 105mm F2.8 EX DG OS HSM offers true 1:1 macro reproduction, and uses a floating focus system to maintain high optical performance at all distances. 
Newly merged Kenko-Tokina has quietly launched the Tokina SD 17-35mm F4 AT-X PRO FX, a semi-fast wideangle zoom for full frame cameras. The company says the F4 maximum aperture makes it easier to produce a smaller lens with fewer aberrations, to sit alongside its 16-28mm F2.8 PRO. The lens features 'SD' glass that the company says offers similar properties to fluorite elements as well as its 'silent drive module' AF motor and high-precision AF position sensor for fast, accurate focusing. No details of pricing
Pentax has announced the 'Q' mirrorless interchangeable lens camera. The camera is the first to use the company's Q mount and features a compact-camera-sized 1/2.3" image stabilized CMOS sensor. This is wrapped in a magnesium alloy body with a distinctly rangefinder-esque design but distinctly compact sizing. Its feature set ranges from the 1080p30 movie shooting (with H.264 compression), to a series of fun filters that can be applied to the Quick Dial on its front plate. We've had a chance to play with a pre-production Pentax Q and have prepared a quick preview.
Pentax has announced four additional lenses for its new Q mount. As well as the kit 47mm equivalent F1.9 '01 Standard Prime' lens that will come with the camera, the company has also announced the '02 Standard Zoom' that will offer 28-83mm equivalent focal lengths. Alongside these will be three more affordable, fun lenses. The 03 Fisheye, 04 Toy Lens Wide and 05 Toy Lens Telephoto are designed to make accessible the creativity that interchangeable lenses can bring. The latter three lenses are all manual focus and fixed aperture to keep costs down.
Leica has announced the Super-Elmar-M 21mm f/3.4, a wideangle prime for its M-series rangefinder cameras. Weighing in at less than 10 ounces, it's extremely compact at just under 2 inches in length. It has a minimum focus distance of 0.7m, and uses a dual-sided aspheric element and 4 anomalous partial dispersion elements in its optical construction. On the M8 camera it offers an angle of view equivalent to a 28mm lens. It will be available from June 2011 at a price of £2025.
Leica has announced the M9-P, a variant of its 18MP full-frame M9 rangefinder camera. The P version gains the sapphire crystal LCD glass previously seen on the Leica M8.2 but now featuring improved anti-reflective coatings for improved visibility in difficult lighting conditions. In order to give an understated appearance, the M9-P omits the traditional Leica red dot and M9 designation from the front of the camera, instead the Leica name is engaved in the metal top-plate in the company's traditional script.
