Sony Alpha 57

When Sony wants to replace a digital photo camera like the Sony Alpha 55, they may want to re-design everything from the ground up ou they can collect all the best from various (recent) sources and create a significant progress. That is the later that the Sony engineers chose when designing the all new Sony Alpha 57: You take most of the contents of a Alpha 55 to cram it into an Alpha 65 body. But they also chose to keep the best technologies to make it better than a rough composite product.

Here is how an Sony Alpha 57 is built:

• A 16.7 MP APS-C digital sensor seen on the Nex-5N
• A body directly drawn from the Sony Alpha 65
• The most recent BIONZ processor
• The autofocus system of the Sony Alpha 55 with some algorithmic improvements
• The EVF of the Alpha 55 (so, quite less impressive than the EVF of the Alpha 65 or the Alpha 77 but… much less expensive)
• The tiltable LCD display of the A55

The shutter is probably a good (complex) mix of technologies already known in Sony with several improvements (allowing 8 fps, or 10 fps if you use a fixed AF, or 12 fps with a reduced resolution).

Video (now compulsory on any new digital camera, SLR or not) allows AVCHD 2.0, and a mode automatically re-framing portraits to help apply the rule-of-thirds (not very software-intensive, but it could help photographers with short-attention span like me),

All the details are on the special page for the Sony Alpha 57.

We will find this Alpha 57 sold from April. Considering the US$700 price, it could well become a very serious contender in the competition to grab the attention of a lot of high-end amateurs or price-conscious experts.

Press Release

SAN DIEGO, March 12, 2012 — A wider palette of creative options is now accessible to more shooters with the α57 camera, the newest addition to Sony’s popular line of A-mount cameras employing Translucent Mirror Technology.

The innovative Translucent Mirror design directs incoming light to the CMOS image sensor and the AF sensor at the same time, allowing full-time continuous AF during both still and video shooting. Users can also frame, focus and preview shots in real-time on the high-resolution Tru-Finder™ electronic viewfinder, which offers a wide viewing angle and 100% field of view. This allows photographers to capture exactly what they see on the screen.

A natural successor to Sony’s acclaimed α55 camera, the α57 is positioned for a wide audience of DSLR users. It can shoot still images at up to 12 frames per second, full HD video at 60p, 60i or 24p frame rates and has a variety of creative modes including Auto Portrait Framing, a world’s first technology.

“Today’s DSLR consumer is looking for a higher level of control and flexibility in their camera,” said Mike Kahn, director of the Alpha camera business group for Sony Electronics. “With the introduction of the new α57, we’re bringing blazing fast response rates, enhanced artistic capabilities and other advanced features to the mainstream DSLR marketplace, offering professional-grade performance at affordable prices.”

With the α57 camera, shooting speeds of up to 12 frames per second are achieved in new Tele-zoom Continuous Advance Priority AE mode, maintaining continuous auto focus and auto exposure with fixed aperture. Magnifying the central portion of the sensor’s image by 1.4x, it’s perfect for capturing split-second action close-ups with a burst of sharply focused images, even when the subject is moving. In this shooting mode, aperture is fixed at either f/3.5 or the maximum aperture of lens in use (whichever is smaller) and image size of photos is about 8.4 megapixels.

Additionally, the α57 camera lets people create powerfully expressive Full HD movies. Responsive full-time continuous phase detection AF ensures that moving subjects stay sharply focused, just like with still shooting. Support for the AVCHD™ Ver. 2.0 (Progressive) format means that Full HD resolution movies can be captured with 60p frame rate: ideal for capturing smooth, blur-free action. Shooting in 24p is also available to give footage a rich, cinematic look. Movie-making options are enhanced further with full control over P/A/S/M shooting modes for virtually limitless creative expression.

The α57 model shares the α65’s 15-point AF system with three cross sensors delivering fast, accurate TTL phase detection autofocus. Newly enhanced Object Tracking AF keeps faces or other selected objects in sharp focus – even if a target is obscured momentarily by another passing object.

Even the novice photographers can now easily create pro-style portraits with the α57 thanks to new Auto Portrait Framing, a world’s first technology. Using face detection and the compositional ‘rule of thirds,’ the camera identifies a subject’s position, trimming the scene to create tightly framed, professional-looking pictures in portrait or landscape orientation while maintaining a copy of the original image. Saving both the original photo plus the adjusted version allows for easy comparison between the two images, offering photographers inspiration to refine their portrait skills.

To get closer to the subject, 2x Clear Image Zoom digital zoom technology doubles the effective magnification of your lens and is a highly practical alternative to travelling with a bigger, bulkier telephoto lens. The camera uses Sony’s “By Pixel Super Resolution Technology” to ensure that cropped and zoomed images retain full pixel resolution.

Additionally, the model’s range of popular in-camera Picture Effect modes includes 11 different effects and 15 total variations – offering a generous palette of ‘PC-free’ artistic treatments, including Pop Color, HDR Painting, Miniature Mode and much more. Results can be previewed directly in live view mode on the LCD screen or in the new Tru-Finder™ electronic viewfinder while shooting either Full HD video or stills.

Still and video shooting, framing, focusing and real-time preview of exposure adjustments are a pleasure with the new Tru-Finder™ electronic viewfinder. With ultra-detailed 1440k dot resolution and a 100% field of view, it rivals quality optical viewfinders. There’s a choice of selectable high-resolution information displays with a wide viewing-angle to help consumers shoot with confidence, including a digital level gauge and framing grid. Information can be displayed either directly in the viewfinder or on the angle-adjustable 7.5 cm (3.0-type) Xtra Fine LCD™ display.

Ensuring detail-packed images, the 16.1 effective megapixel Exmor® APS HD CMOS sensor is teamed with a latest-generation BIONZ® engine. Refined by Sony during the development of its flagship α77 and high-end α65 cameras, this powerful processor effortlessly handles large amounts of image data for flawless, low-noise images and Full HD video.

Thanks to the BIONZ processor, creative shooting opportunities are boosted by an outstanding sensitivity range of ISO 100-16,000. Users will experience consistently natural, low-noise images – whether shooting at fast shutter speeds to freeze dynamic action or handheld without flash in low light.

Pricing and Availability

The new α57 interchangeable lens camera will be available this April with an 18-55mm kit zoom lens for $800 (model SLT-A57K). It will also be offered as body-only for about $700 (model SLT-A57).

Sony will also be introducing a new battery-powered LED video light, model HVL-LE1, which broadens options for recording video indoors or in low light. This new accessory will be available this month for about $250.

More later.

The most recent release of Capture One (version 6.3) now supports the new RAW files grnerated by the most recent Sony products using the huge 24 MP sensor:

• Sony Alpha 77
• Sony Alpha 65
• Sony NEX-7
• Sony NEX-5n

We should also list the support for the most recent Olympus:

• Olympus E-P3
• Olympus E-PL3

Everything points at a sound produces inside the camera bod (it can be heard from the outside, but it is mostly audible in the recorded sound taken using the internal mike of the NEX-5N). But it’s already a known problem of the NEX-5. Some would like to think that this is the beginning of a PR nightmare for Sony. But the past experience of the Nex5 and the overheating sensor video issues seem to have always been handled by Sony without grave problems in front of customers who only marginally worry about these (these are acceptable issues, somehow).

What is an EVF?

EVF = Electronic View Finder.

Be ready to see this term used more and more, even for SLR cameras. Many a compact point-and-shoot photo camera already is equipped with an EVF, but it is most common in video cameras (and it has been for many years already). In the viewfinder, instead of looking at an image coming from a more or less complex optical system, your eye is pointed at a small LCD screen (or TFT, or OLED or whatever similar technology) reproducing the picture recorded by the CMOS imaging sensor of the camera.

After all, this is only what we already know well as the LiveView mode on the back LCD of nearly all the compact photo cameras (and many SLR too). But as a small picture in the viewfinder.

An LCD display + a viewing lens = an EVF.

In some case, you could add a small mirror for space reasons, but this is a minor variation to the original tune.

EVF and Single Lens Reflex (SLR) cameras

SLR viewfinder

A Single Lens Reflex (SLR) photo camera is organized around a very mature technology in which a mirror reflects the image through an eyepiece via a pentaprism (or a penta-mirror) as in the drawing on the left.

Of course, as the film (film plane and focal plane shutter) is hidden by the mirror, this one must be drawn up to take the snapshot.

All this is greatly simplified when there is an electronic viewfinder.

Advantages and drawbacks

Advantages et gains from an electronic viewfinder

The first positive side is mechanical and optical: If you remove the mirror and the pentaprism, the architecture of the camera will be greatly streamlined, lightened and its manufacturing cost will go down. For three different reasons (at least):

• reduction of the number of parts
• reduction of the assembly complexity (or of the amount of human work needed)
• increased ease of calibration (alignment) of the optical parts (an LCD and an eyepiece, rather than a whole bunch of parts)

Even better, the disappearance of a huge articulated and mobile mechanical system brings several positive effects:

• increase of the continuous shooting speed/cadence (there’s so much less hardware to move around for a photo)
• reduction of shutter noise (in a traditional SLR camera, most of the noise actually comes from the mirror up-swing and the shutter operation; It’s worth removing one of them)
• a lighter mechanical structure through reduction of the quantity of parts and since the enclosure is lighter because it has less stress to sustain in all these shocks and moves

Also, the electronic viewfinder exactly reproduces what the sensor sees. A 100% optical coverage on a viewfinder of fully optical design has always been reserved to the most expensive SLR cameras. But when you get an EVF, 100% coverage is totally natural and effortless. Luxury comes to you in the clothes (and price) of entry level.

Then, having an LCD display brings the additional possibility of adding all the data you can think of. Many brands already experimented with this and brought us some Electronic Viewfinders with features like:

• Histogram
• Artificial Horizon
• Zoom on a part of the image
• Telltales and technical displays (aperture, speed, ISO, etc.)
• Active AF zones (including face detection)

As a matter of fact, there is no other limit than what a computer screen can display: Data, image, etc. It’s only a choice from the designer.

And it’s not even the end of it. The EVF also has a major advantage when light is low: As far as the sensor can see something, it’s only a matter of amplifying light signal (like for the ISO sensitivity selection) to make the picture readable. If the photo is possible (even barely possible), showing it is possible. Think about it! A nikon D3s digital sensor could display what it sees even in the darkest dawn it can manage. Since the digital noise is only a marginal issue on an LCD display (even at 3MP resolution), you can see what the sensor will be able to grab even in a room too dark for comfortable framing with an optical viewfinder.

If you compare it with the lowest-priced optical viewfinders of entry-level SLR cameras, the EVF is an easy winner in those low-light conditions: These simple viewfinders where already unpleasant and dark, the EVF bring a new life to cameras used indoors.

Drawbacks and limitations of the electronic viewfinder

But all is not pink and shiny. EVF have the same problems as most point-and-shoot cameras find on the rear-side LCD displays used for LiveView.

To start with, even if the electronic viewfinder (EVF) is intrinsically better protected against sunlight, it is still very sensitive to bright light issues. If there was only one thing that the EVF-sensor pair does not like, this would be high lights and bright sun (sic!) highlights are easily washed white and overblown. You will find more white flat areas than nice clear zones. The worst comes when you add high contrast to the picture. The EVF has a very small dynamic range (this is not HDR!) and the designer must choose between high-lights and dark areas.

We tend to forget it, but the human eye is amazingly sensitive and adaptable. Behind a prism and a mirror, in the brightest mid-day sun light, it can marvelously adapt to over-exposure situations that totally saturate the purely digital EVF system.

Best (or worse), the eye is extraordinarily able to switch within a few hundredth of seconds from the darkest night to the most violent lighting without even thinking about the marvelous brain processes involved. On the contrary, the EVF system uses a gain correction which will change at any time the apparent brightness to track the actual scene brightness. What is clearly an advantage in a dark room, forces the system to include an auto-adaptation feature which will change the brightness of the EVF several times per second. According to what you point the camera to, the electronic viewfinder will change from lighter to darker display. Not really a problem, but this asks for some tolerance to a process which is not natural to our human eyes. You have to get used to it.

Additionally, but this is all very sensitive to the user (you!), watching a computer screen may be more or less comfortable in the long run. As a matter of fact, if you use the EVF for long hours (this is the case for the professional photographer waiting in front of the Cannes Festival stairs, for the photo safari amateur or for the intensive tourist photographer willing to bring everything on a memory card – don’t laugh, I’m sure you shoot it as much as I do), you may come back with a serious headache. This is certainly not an issue for everybody (and you’re not supposed to keep the camera to your eye if you want to immerse yourself in your subject), but this may become a real limitation to some people. At the strict minimum, you must take very seriously the setting up of the dioptric correction of the eyepiece (much more seriously than on your current camera) to limit the impact to a tolerable level. Unfortunately, the eye seems to get more prone to this issue when the photographers gets older… Our eyes are not equal in front of photo gear. Too bad, but true.

Sony Alpha : miroir semi-transparent et EVF

Last but not least, even if the electronic viewfinders improve in time (and Sony has shaken the market with a 2.3-million-pixel EVF in the Sony SLT-A65 and in the Sony SLT-A77 which has raised the bar to a whole new level for all the competition), the fine quality of a focusing screen in a common optical viewfinder stays incomparably better than what the best EVF can display today. Far better! This is the reason why they generally include an additional Zoom feature allowing to better judge focus through enlarging an area (On the opposite, a company like Zacuto proposes an enhanced edge sharpening to make the focus analysis easier or more natural).

If you let your camera focus for you, honestly, you shouldn’t care much about this. If you like to fine-focus your pictures (all the more if you use a USM, SSM or similar lens which allows easy manual focus correction), if you use wide-aperture lenses (which call for a very attentive selection of the focus location or AF area), you will be in a living hell playing with buttons to merely focus while you were used to just looking at the image in your old optical viewfinder. Interestingly, Sony keeping in its technological portfolio the marvelous AcuteMate focusing glass surface (bought from Minolta and still widely considered as the absolute best here), is the first to jump to the next technology.

While we talking about AF, we must stop and remind ourselves that the disappearance of the reflex mirror means that focusing is now done from the data directly available on the image sensor. Where the traditional SLR camera focuses just before the exposure, using phase difference sensors (high precision, high speed, and not very complicated), the EVF viewfinder seems to enforce the use of automatic focusing using the measurement of a contrast difference directly on the image (very consuming in terms of processor power, intrinsically less reactive). Sony, once again at the forefront, chose to insert a semi-transparent mirror to keep the fast phase detection sensors. But they are quite alone in this decision – for now.

(Temporary?) conclusion

The electronic viewfinder is no panacea. But it brings good answers to tough questions asked by the old reflex technology, starting with price reduction for the digital photo cameras which is always a major issue for the manufacturers.

The camera owners already used to the optical viewfinder of entry-level cameras will immediately recognize the many advantages and all the more if they are occasional photographers or if they come from the compact point-and-shoot camera world.

Expert users (not even pros) will certainly have more mixed feelings, even if the most advanced electronic viewfinders like the recent Sony ones progressed in great strides. As I read in one of the recent articles about these new photo cameras, Sony brought enormous (not incremental) progress but this is still an electronic viewfinder. Not perfect, but with enough advantages to balance the drawbacks.

Now, you may have to read the post again to choose which ones are the most important for you. But there is a big problem left: We usually choose our photo camera inside a relatively dark shop (perfect, ideal conditions to demonstrate an EVF) and we use it mostly during our Summer holidays (the worst conditions to use an EVF). Some people may be unpleasantly surprised if they do not think twice before choosing a camera.
