Sony SLT-55 Review
Revision based on a production Sony SLT Alpha A55V with firmware version 1.0Latest Sony interchangeable lens system cameras, the SLT Alpha A33 and A55 represent a technological milestone-not only for Sony but for the entire camera enthusiast market.The company rejected the traditional DSLR design and instead created a hybrid that, as a compact camera, is built from the ground up around live view, but what is also able to offer full-time DSLR-style phase-detection autofocus. The combination means can offer features such as phase detection AF during movie recording and amazingly fast continuous shooting rates (10 frames per second at A55), unthinkable at this price.This is made possible by adopting an approach that has more in common with a mirrorless camera (such as the Panasonic G2, for example) a reflex by removing bits which practically define these cameras: the optical viewfinder and moving mirror.The name ' slt ' stands for single lens is translucent and the bit ' translucent ' that is the key to what differentiates these new models from both conventional DSLRs and interchangeable lens mirrorless cameras. The SLTs are mirrors, but are mirrors that allow most of the light passed straight to the sensor, rather than having to swing out of the way to allow for exposure. Consequently they are fixed in position, always reflecting a part of the light emerging from the back of the lens on an array of phase-detection AF housed at the top of the camera. (A newly-developed 15-an array of points in the case of these two cameras).The APS HD CMOS sensor A33 features the same 14 million as the NEX-3 and NEX-5, but the sensor A55 is brand new, with 16.2 million effective pixels-maximum resolution APS-C format sensor Sony yet. In another first for big models of Sony interchangeable lens body, both cameras can shoot well, movie files to 1080p HD resolution. Technically this review was conducted with a A55V SLT: Variant enabled GPS camera that will be sold in most markets – only a handful of countries (including Japan), will be a non-GPS A55 sold.

Panasonic Lumix DMC-GH 2 Preview
server temporarily unavailable
Preview based on a pre-production GH2 When Panasonic first launched the GH1, its second Micro Four Thirds camera, it was widely seen as simply being a G1 with video shooting and a considerably more expensive kit lens. And, if your primary concern was stills photography then this wasn't an entirely unreasonable assessment. However, its real appeal was not that it had video, but that it offered what was, at the time, some of the most flexible, high quality video available. Again, the 14-140mm F4.0-5.8 kit zoom may not have been cheap but it had been specifically designed and built with fast, quiet autofocus and stepless aperture control to allow AF during movie shooting and exposure changes without sudden changes in brightness.
Now that the G2 (along with the majority of contemporary cameras) is able to capture HD video, the distinctions between just being able to shoot HD and to really control it become more apparent. Stills shooters may get some advantage from the new, higher resolution sensor but the main differences between the GH2 and G2 are the ability to control the movie shooting process (both in terms of frame rate and shutter speed).
In the twenty five months since Olympus and Panasonic jointly announced the Micro Four Thirds standard there have been eight models launched to date, seven of which share the same 12MP sensor. The only exception was the GH1 which, despite its 12MP output actually featured a 14MP sensor. The sensor was slightly larger than the format's imaging circle, which allowed it to deliver images in different aspect ratios while retaining the same image diagonal. And now the GH2 follows the same pattern, shooting 16MP images using its brand-new, similarly over-sized 18MP sensor.This sensor is capable of much greater output speed than its predecessor, bringing a host of benefits. Videographers will see an improvement in the quality of the highest quality output - the 1080i output is derived from 60p or 50p capture, rather than doubled-up from 24p or 25p on the GH1. However, the faster readout also means the AF system can more frequently check the accuracy of its focus, meaning faster autofocus (on lenses that can respond quickly enough). Finally, the faster readout means the live view is updated 60 times a second (rather than 24fps displayed at 60hz), giving a smoother viewing experience with less tearing.The viewfinder has also been slightly widened - it now shows 852 x 600 pixels (rather than 800 across) to allow it to show 16:9 and 3:2 previews without the need for such extensive cropping as before.• 18.3 million total pixels

Preview based on a production E-PL2, firmware 1.0
The Micro Four Thirds system turned two years old last October, and a lot has happened since Panasonic debuted the DSLR-inspired, but mirrorless Lumix DMC-G1. What was then a brand new system has had time to mature, and mirrorless interchangeable lens cameras (ILCs) now make up one of the fastest-growing and competitive segments of the consumer digital camera market.
Although the Micro Four Thirds system got in first, Panasonic and Olympus haven't had everything their own way. After a decent head start, Panasonic's G-system and the Olympus PEN-series have been joined by Samsung's small-but-growing NX range, and Sony's innovative NEX-3 and NEX-5. All this competition has resulted in a rash of new releases from both 'original' mirrorless ILC manufacturers in recent months, as Panasonic and Olympus attempt to consolidate their early lead and grab as much market share as possible.
Part of that strategy is to aim lower, at novice rather than solely enthusiast consumers. The Olympus E-PL1, released in February 2009, was designed to appeal to precisely this market, filling the gap between high-end compact cameras and enthusiast-oriented, mostly DSLR-inspired, ILCs. The E-PL1 dispensed with the control dials of the E-P1 and E-P2, but retained the same sensor (albeit with a lighter AA filter), in a smaller, considerably more compact-like body. It also boasted - gasp! - a built-in flash; something which Olympus opted to dispense with in both the E-P1 and E-P2.
The E-PL2 has the same sensor as the E-PL1 and doesn't officially replace it, but sits above it in the product line, beneath the E-P2. As well as a physical makeover (the E-PL2 reminds us slightly of the rather beautiful Stylus Verve) its ergonomics have been refreshed too. The all-button operation of the E-PL1 has been ditched, in favor of a more conventional combination button/dial approach, with a rear plate that's much closer in design to the E-P2 than the E-PL1. The LCD screen is better too - its size has increased to 3 inches and it doubles in resolution, topping out at 460K dots. Indeed with its 3:2 aspect ratio and deep blue anti-reflective coating, it bears a startling resemblance to the unit used on Panasonic's DMC-GF2, although without that model's touch-sensitivity.
There are a couple of specification and firmware tweaks, too. The available ISO range now covers 200-6400, with the low-noise but limited-dynamic range ISO 100 option dropped. There's also an intriguing extension of the familiar face-detection AF mode, in the shape of 'iDetect' that aims to focus specifically on your subject's eyes. Some of the Art Filters gain a number of variations, plus the ability to add a stylized border.
The E-PL2 also comes with a new kit lens, that made its debut alongside the Japan-only E-PL1s late last year. The collapsible M.Zuiko Digital ED 14-42mm f/3.5-5.6 II MSC is 25% lighter than the previous generation, but boasts three aspherical elements rather than two. Its mechanism has also been modified, with one extending barrel section rather than two, making for a more solid construction than its notoriously-wobbly predecessor. It also gains a bayonet fitting at the front which can accept not only a lens hood, but also a new series of add-on lens converters - fish-eye, wideangle and macro.
Perhaps most significantly, though, the lens now gains the 'Movie and Still Compatible' (MSC) designation, signifying a much faster and quieter internal-focus design. According to Olympus, this makes the AF speed of the E-PL2 and 14-42mm II combination on a par with the best cameras in its class. However it does come at a slight cost to the lens's macro capability, with a maximum magnification of 0.19x rather than 0.24x.
A full test of the E-PL2's AF capabilities will follow in our forthcoming review, but Olympus's claim that the E-PL2 with the new kit lens offers faster AF than the previous generation E-PL1 with the original 14-42mm is born out in our initial testing. Although from our measurements the speed difference is not enormous, we have found that on the E-PL2, the new 14-42mm II can reliably achieve focus in slightly less time than the older lens. The speed increase is small - typically in the region of 0.1s - but enough to make it feel more positive. This is especially true when refocussing across a small distance range, at which point the E-PL2 with 14-42mm II feels pretty close to instantaneous.
It is worth noting that E-PL1 users will see a significant leap in AF performance from the new 14-42mm II. With the new lens mounted, we found that AF aquisition is typically around 0.2secs faster than when using the original kit zoom. This amounts to an increase in AF speed of almost 30% in some circumstances - a substantial boost. Back to the E-PL2 though, and the impression of better AF speed is aided by the silent focussing of the 14-42mm II. Not only does this make the lens feel swifter in use, but crucially it also means that movie footage from the E-PL2 is not marred by the sound of the lens' AF motor racking back and forth.
Although the E-PL2 is a less expensive camera than the E-P2 that sits above it, it gives very little ground to its big brother in terms of specification, and is better specified than the E-PL1. The biggest differences between the E-PL2 and E-P2 are in fact cosmetic and ergonomic: the E-PL2's more compact-camera-like interface, the simplified construction and of course the slightly more compact, more 'styled' body shell.
One control dial (vs. 2 on the E-P2)Built-in flash (external flashes only on E-P2)Compatible with Penpal PP-1 bluetooth accessory (the E-P2 is incompatible).Direct record movie button vs. movies as position on E-P2 mode dialMono mic with option to add stereo using adapter vs. built-in stereo micsNo orientation sensor on E-PL2The omission of the uppermost control dial and the addition of a direct video recording button, plus (of course) the flash release catch are the only differences between the two cameras in terms of physical control points, but although we're looking at the same number of buttons in more or less the same place, their functions have been shuffled around a bit. Perhaps most significantly, the E-PL2 sports a magnification button (for both image review and manual focus) in place of the E-P2's dedicated AEL/AFL button.
