Apple iPhone 3GS s lence pass and missed iOS 5

iPhone4S, iPhone5, iPhone4S, these terms are likely to become the official definition of the next generation iPhone, of course, all is not possible. Perhaps everyone EldarMutazin the name is very familiar, and recent editor of the Russian MobileReview site once again express his personal opinions, forecasts will not upgrade to iOS5 iPhone3GS operating system, iPhone4 would normally upgrade to iOS5 intelligent systems.

Apple remained silent mass iPhone3GS and iOS5 missed
before final confirmation in Apple official, the General Assembly passed a lot about the WWDC news content, there is news that the WWDC conference new iPhone, does not appear that Apple will focus on new iOS systems and related services and promotion. The next generation of iPhone has not yet appeared, Eldar remarks gave no clear now the situation had cast a veil, Eldar last week predicted that Microsoft will buy Nokia mobile sector, news that the talk of the town, the upgrading of iOS5 matters to make bold assumptions again, credibility is uncertain, only for your reference.

Beyond GF2/GH2 new flagship Pan sonic G3 test!!

Compared to GF, GH series, Panasonic G series of single power product less attention has been too high. GF Series flagship compact and lightweight because, GF1, GH2, respectively, won the “One girlfriend,” “Girlfriend II” reputation, GH series flagship high-definition video, GH1, GH2 also are the hot pursuit of high-definition camera enthusiasts, while the G series stressed SLR line, the main idea of ??SLR-like photography, has become a single power in the heterogeneous. G1, G2 are not tepid, but Panasonic has just recently released a new LUMIXDMC-G3, with the current Micro4 / 3 system, the highest 1630W pixels LiveMOS sensors, full HD video support 1920×108060i/30p and support Panasonic cited proud of the world fastest 0.1s contrast AF system, then the Panasonic LUMIXDMC-G3 before the G Series can turn this “single-power heterogeneous” embarrassment?
This article is compiled articles, which read “PanasonicLUMIXDMC-G3M43rdsFirstImpressionsReview”, thanks ephotozine website and the original author.

1630 megapixel CMOS image sensor
Panasonic LUMIXDMC-GH2 release, including Olympus, including the M4 / 3,4 / 3 sensors are 1210W, even after some minor improvements, but with the APS-C frame pixel has grown to the 1600W-1800W-pixel level, this sensor has Get the lead, has been behind many of the pixels. Again, due to the sensor area of ??the tired, high-quality performance is always not a very good sense. Panasonic LUMIXDMC-GH2 uses 1605W effective pixels pixel sensor has been increased though, and there is a degree of high quality to enhance a sense, but because the sensor size remains unchanged, the high sense of quality improvement is not a qualitative improvement.
Panasonic 1630W used LUMIXDMC-G3 sensor Effective pixels LiveMOS LUMIXDMC-GH2 looks the same as with the Panasonic, but Panasonic that this is a new product, the use of “low-noise pixel signal is read out circuit “and a new” low noise amplifier signal / noise cancellation circuit “, signal to noise ratio (S / N) improves by 6 dB in the ISO3200, ISO6400 is the improvement of 9 dB, without increasing the sensor area on the basis of improved a sense of quality high-quality, high sense of quality that is more smooth. New 1630W 1630W pixels LiveMOS sensor pixel sensor structure LiveMOS
In addition, because Panasonic LUMIXDMC-G3 with a new generation of image-processing engine Venus IVFHD, more computing power, sensor hardware and machines in LiveMOS Treatment of the double combination of powerful software under the camera, though still only with the same ISO6400 LUMIXDMC-G2 highest sensitivity, but its quality performance has been quite different.
before Micro4 / 3 system high sense of quality has always been a problem, and some even returned to the performance level of their cards labeled with the label of the same level, more than ISO1600 basic intelligence to emergency, the Panasonic LUMIXDMC-G3LiveMOS sensors to improve, it will completely change our understanding of this before, although still affected by the size of APS-C frame can not be comparable, but LUMIXDMC-G3 has been done within the limited size of the best high specific a sense of quality as we will show you below.
0.1 s ultra high contrast type AF system
0.1 s ultra high contrast type AF system is still in the first Panasonic LUMIXDMC-GH2 , we had “GF2 missed the complaint about the secret behind the Panasonic GH20.1s Focus” article to find out more analysis of this technology. Panasonic LUMIXDMC-G3 sensor in the AF state will 120fps high-speed refresh, refresh rate of 60fps, compared to double before, especially with high-definition video for optimized LUMIXGVario14-140mmF4-5.6MEGAO.ISHD lens, you can achieve the most Contrast type AF 0.1 seconds faster. Figure 1: The phase-detect AF and contrast-type AF works
phase detection AF can instantly detect the focus position, forward or rearward, while the comparison is to contrast type AF search maximum contrast, there is a repeated search process (Figure 1), so the phase-detect AF speed compared with its inherent disadvantage. To improve the speed of contrast-focus, first of all, we must strengthen the communication between body and lens, the camera lens can accept the current real-time data, the information needed to master the body. Second, even if is to strengthen the communication between body and lens, if the lens focus speed is slow, still can not improve the overall focus speed, so the focus needs to be developed faster lenses. Third, accelerate the auto-focus system sensor sampling rate, improve focus feedback loop (refer to the information transmitted back to the lens), it is in-depth research on the above three points to ensure that the M4 / 3 system, with more contrast-type AF fast.
To achieve the above three points, Panasonic LUMIXDMC-G3 made the following three points: to strengthen communication between the lens and body, in the M4 / 3 system, the link body and the lens is shock 11, compared with 4 / 3 system more than two (this point also has one other Panasonic micro, such as Panasonic GF2, G2, etc.). Second, improve focus sensor refresh rate, DMC-G3 is 120, which is the second reading 120 images, while focus position can be adjusted according to the focus of the search speed, for example, when far from the focus position when the acceleration detected When you slow down when approaching return of the focus detection accuracy, while the Panasonic DMC-G3 models before the focus can only provide the refresh rate of 60 frames, and can only speed the search function does not have the focus, in focus throughout the flat detection ( see below).
Panasonic emphasized again 0.1 seconds to achieve ultra-high-speed focus, you must use LUMIXGVARIOHD14-140mmF4-5.8ASPH.MEGAO.IS lens, because the camera uses a linear direct-drive motor and weighs only 3.8g focusing lens, all 0.1 seconds to achieve ultra high speed focus, Panasonic DMC-G3 and LUMIXGVARIOHD14-140mmF4-5.8ASPH.MEGAO.IS lens indispensable.
Today, Panasonic 0.1 seconds on the AF system is almost at the speed can not be exceeded, whether or contrast-type AF phase detection AF system.
more compact, lightweight design
Panasonic LUMIXDMC-G3 uses aluminum alloy material, so Panasonic LUMIXDMC-G2 compared to the volume or both weight has decreased, the volume of which the most obvious aspects, Panasonic LUMIXDMC-G2 smaller than about 25%. To reduce the size, Panasonic LUMIXDMC-G3 exterior design change is also very obvious, and now the handle design is similar to the performance level LX5 hot similar, more streamlined, but also the right position before the shutter handle protruding above the top of the transfer to the body, shooting touch LUMIXDMC-G2 than a certain decline. In addition, the camera body has no “G3″ this model of identity and replace it with “G” letter, do not know the Panasonic next GH3, GF3, and other models will not only keep family name, rather than identify the specific model. Panasonic LUMIXDMC-G3 Left: Panasonic G3 right: Panasonic GH2
Panasonic LUMIXDMC-G3 back is still a 46W-pixel 3-inch touch screen, support for multi-angle rotation, can be adapted to a variety of camera angles, and GF2, GH2, G2 the same, although the pixel-pixel compared with the existing gap between the mainstream 92.1W, but feel very good touch, we have in the “handling comparable to iphone4 Panasonic GF2 video analysis,” an article by the way as we interpret the video Panasonic LUMIXGF2 the same touch as iphone4 pleasure, this is not any one of 92.1W pixel display available. Panasonic G3 back left: Panasonic G3 right: Panasonic GH2
Panasonic LUMIXDMC-G3 in the back of the retained “a dual-use” electronic trackwheel, you can press the trackwheel, then they can be another parameter manipulation, such as in aperture priority mode, the default size for the aperture control, press the exposure compensation can be carried out after a trackwheel can have the effect of two trackwheel, Panasonic this design very creative. Panasonic LUMIXDMC-G3 back buttons have also been slightly adjusted to cancel the AF / AE lock button, and an increase in the position of a video capture key, Q. MENU and DISP keys and custom keys display Fn1, Fn2 share, G2 Cross control area from the original definition of Fn key into the shooting, regular camera and other capture mode switch key.

streamlined body control settings < / strong>
Panasonic LUMIXDMC-G3 G2 left and right shoulder by a two-wheel design into a single wheel design right shoulder, left shoulder to cancel the original focus mode dial, the control area by left-back cross to adjust, while the right shoulder of the shooting mode dial also been streamlined, the most obvious is the landscape, portrait and other shooting mode is canceled, leaving only the P, A, S, M, filters, scene selection, and C1/C2 from definition of design, the mode dial is more like high-end SLR. In the mode dial to the right to retain the “iA” intelligent mode button, but Panasonic has been upgraded to iA G3 mode, iA Intelligent Auto technologies, including enhanced optical image stabilization, personal identification, intelligent scene selection, intelligent iso, intelligent scene control functions can automatically capture and HD recording double pleasure. Panasonic LUMIXDMC-G3 shoulder Left: Panasonic G3 right: Panasonic Panasonic G2
key LUMIXDMC-G3 compared to G2 and streamlined wheel design looks a lot, but before the G3, however, has a GF2, G2, GH2 do not have the function of the camera, that is, the Panasonic LUMIXDMC-G3 support full-screen touch screen, rather than the GF2, G2, GH2 only a fixed area as support for touch, so Panasonic LUMIXDMC-G3 almost all of us required parameters can be directly on the touch-screen operation, and touch more sensitive, I think this is Panasonic LUMIXDMC-G3 button and dial design to streamline the reasons, allowing users to choose more touch operation.
EVF electronic viewfinder camera remains at 144W pixels, display crisp and clear, light sound effect of the environment close to the optical viewfinder, but unfortunately, the EVF Panasonic LUMIXDMC-G3 abolished light induction device, not as close as the G2 to automatically turn off EVF LCD display. The camera uses the DMW-BLD10E lithium battery-powered, capacity 1010mAh, CIPA standard test can be taken 250 or more. BLD10E Panasonic Battery
LUMIXDMC-G3 in the 1630W can be achieved when all 4 pixels / second continuous shooting speed, and the use of electronic shutter, the 400W can achieve 20 pixels / second high speed continuous shooting, With the high x2 telephoto conversion rate on the ecological aspects of photography helpful.
1920×1080 Full HD video
Panasonic LUMIXDMC-G2 which has 720pAVCHDLite HD video recording capabilities, LUMIXDMC-G3 was the perfect upgrade finally reached FullHD 1920×1080 resolution video capture, recording 1080i video 60 frames per second (bit rate 17Mbps), but the output is only 30, and supports stereo recording, the use of AVCHD packaging formats to meet the needs of multimedia enthusiasts. Meanwhile LUMIXDMC-G3 format also supports high-definition 1280×720 video format, but did not carry LUMIXDMC-GH2 24Mbps high rate mode. Panasonic video camera has been the focus performance of the force, this is not to worry, LUMIXDMC-G3 can also be achieved in video focus the powerful ability to recover.
same time, to pull with the Panasonic LUMIXDMC-GH2 gaps in the video, the distinction between the concept of GH series flagship high-definition, LUMIXDMC-G3 only supports the interlaced 1080i format, does not provide support LUMIXDMC-GH2 Progressive scan 1080p video option, which is LUMIXDMC-G3 and GH2 the apparent gap in the video. In addition, Panasonic LUMIXDMC-G3 video capabilities with his girlfriend II “GF2″ consistent.

white balance preset and the frame ratio
Next look at the Panasonic LUMIXDMC-G3 white balance mode, the automatic setting When white balance is very accurate, fine-tuning can be corrected by custom to the more accurate, close to the real world colors. Tungsten white balance, auto white balance custom white balance
Panasonic LUMIXDMC-G3 addition to the regular 4:3 recording modes, and also increased the ratio of 1:1 mode 3:2,16:9 However, the relationship between the proportion of the sensor, in addition to 4:3 mode, the other models are coming through the cut. 4:33:216:91:1
creative mode / photo mode
Panasonic LUMIXDMC-G3 also offers a wealth of creative modes (before the “My Colors”) and photo mode (before the “movie mode”), creative model includes retro, high-profile, nostalgia and high dynamics, and photo models include standard, vivid, natural, monochrome, landscape, portrait, etc. and so on.

proof sensitivity Test
Panasonic LUMIXDMC-G3 provides a sensitivity range of ISO160-ISO6400, high sense and low sense of setting the relative bit conservative. Through testing, the ISO160 Panasonic LUMIXDMC-G3 performance of fine quality, well until the ISO1600 can keep the details relative to the Panasonic LUMIXDMC-G2 has been greatly improved, ISO6400 although the details of performance significantly decreased, but relative to the APS-C also almost the same format cameras, and Panasonic LUMIXDMC-G2 prior to the time of the ISO6400 noise performance has been miserable. Overall, the ISO6400 Panasonic LUMIXDMC-G3 G2 is almost equivalent to the ISO1600. ISO160ISO400ISO800ISO1600ISO3200ISO6400 Panasonic LUMIXDMC-G2: ISO6400

test summary
The ephotozine Panasonic LUMIXDMC-G3 site testing is not in the official version of the firmware, which may also provide proof of the original site is not large Figure reasons, because the test the firmware and do not represent the final listing of the true level of quality LUMIXDMC-G3. But we can also test throughout the approximate spy LUMIXDMC-G3 quality performance, especially in the high sense of quality performance, enhance image quality is very obvious compared to G2.
Panasonic LUMIXDMC-G3 more compact body, focusing capacity of the same with GH2 ultra-fast 0.1 seconds, and supports 1920×1080 format video, touch operation is also more convenient, most people pleased that the G series has finally got rid of that piece of 1210-pixel CMOS sensor, using the more outstanding 1630WLiveMOS quality sensors, I think they have enough people satisfied.
Back to the article begins with the question, Panasonic LUMIXDMC-G3 can change in the light before the G Series GH Series HD between GF and rather embarrassing situation, whether the frame SLR with APS-C competition in general get a place? Large compared to the current hot GF2, Panasonic LUMIXDMC-G3 are super-focus advantage, and GH2 than the Panasonic LUMIXDMC-G3 also has a price advantage. The limited by the frame, quality has not been the Micro4 / 3 system, the advantages, so there must be characteristics of the camera to be in the price of SLR with APS-C frame stand out quite the case, and now Panasonic LUMIXDMC-G3 have done this point: the category iphone4 like touch experience, 0.1s high-speed focus, strong video capabilities, the Panasonic LUMIXDMC-G3 enough to get people attention.
Of course, Panasonic LUMIXDMC-G3 can eventually be accepted by the market, the ultimate determining factor is price!
