Sony Alpha a57 Price in US

In 2010, Sony introduced its ground-breaking SLT technology with the SLT-A55 and SLT-A33 models, both of which were pleasant to novice users. The company’s dedication to competing with Canon and Nikon in the market for entry-level DSLR cameras was underlined by the sheer ambition of a transparent fixed-mirror design that utilized an electronic viewfinder rather of an optical viewfinder. The Sony SLT-A57 is an upgrade of the A55 that was released by the corporation without the usual hoopla that surrounds the introduction of revolutionary technology. In point of fact, there is very nothing in the way of features or handling that can be found on this model that is not also available on another model in Sony’s SLT portfolio.

However, this does not mean that the A57 should simply be written off as a subsequent iteration of the product. We have seen a number of improvements to the Alpha lineup in the two years since the launch of the original SLT. Simply by bringing the A57 up to date with current SLT models, Sony is offering novice DSLR users a significantly enhanced user experience compared to that which was offered by the first-generation A55. One of the features that did not make the cut for the upgrade, however, was the built-in GPS module that was included in the A55. This means that if geo-tagging plays a role in your workflow, you will need to purchase an extra external device.

The biggest noticeable difference between the A57 and the 24MP SLT-A65 is that the A57 has a bigger form factor and an exterior design that is almost exactly the same as the SLT-A65. The highest possible frame rate for still photographs has been raised to 12 fps (albeit with the camera set to a lower resolution 8.4MP crop mode). The video specification has been updated, and users now have the option of shooting 1080p video at either 60 or 24 frames per second (50 or 25 on European models). The well-known high-contrast edge-enhancing ‘peaking’ function is offered as a manual focus aid in both the stills and video modes of the A57, but the camera’s autofocus mechanism is the same as that of the A55: 15 points (also used in the A65).

The ‘Clear Image Zoom’ digital zoom capability is now available in Sony’s SLT camera lineup for the first time thanks to the A57. Previously, this function was only available in Cyber-Shot models. Clear Image Zoom makes use of an image database to do an interpolation between acquired pixel data in order to provide what Sony claims to be output with full resolution and no discernible loss in quality. The A57 makes even more use of this capability by including a setting that will reprocess your photographs of people with what it considers to be a more pleasing arrangement on its own will. When you select the Auto Portrait Framing option on your camera, it will look for faces and then re-crop the image so that it is in portrait orientation with the subject’s eyes aligned along a rule-of-thirds grid. Clear Image Zoom scaling is then used to “intelligently” increase the resolution of the cropped image back to 16 megapixels.

In spite of all of this camera’s cutting-edge technology, the viewfinder on the A57 is still a 1.4 million-dot LCD, the same device that we saw in the original A55. This is in contrast to the high-resolution OLED finder used in the A65 and A77, which are the camera’s more expensive siblings. However, there have been a few adjustments done. In order to make it possible to view more of the display, the magnifying lenses that are located in front of the LCD panel have been changed. There are also two other magnification settings available inside the viewfinder itself. These modes are meant to adjust the eyepoint (viewing distance) of the finder, making things simpler for those who need to wear corrective lenses.

Despite the fact that the A57 does not offer the same resolution as its high-end relatives, Sony’s current 16MP CMOS chip is among the best-performing sensors available for entry-level to mid-range APS-C cameras. And the A57 comes equipped with the most recent revision of the BIONZ processor developed by the business.

Good

The A57 has a sensor with a high-resolution of 16 megapixels, straightforward access to the shooting controls, and the best video performance in its class. And it achieves all of this while maintaining a consistent shooting experience, regardless of whether you compose your shots using the electronic viewfinder (EVF) or the back LCD.

Pros
  • Very excellent Raw file output all the way up to ISO 6400 Dynamic range that is unmatched in its class
  • An electronic viewfinder with a high magnification and a detailed information display
  • "Peaking" option for manual focus, available for both still and video shooting modes
  • Large picture buffer space and significantly reduced write times (compared to A55)
  • Battery with a high capacity
  • Eye sensor for toggling between the electronic viewfinder (EVF) and the back LCD mirrors the form factor and body design of the higher-specified A65.
  • Operation that is quick and responsive
  • Two buttons, AEL and ISO, that are fully programmable and offer a diverse set of possibilities
  • Access to the shooting parameters may be gained via the convenient function menu.
  • Fully articulating LCD on the back for a variety of different viewing angles
  • video resolution that is at the top of its class 1080/60p with customizable exposure control
  • capturing images at a full resolution at 10 frames per second
  • Optional live view exposure simulation
Cons
  • LCD viewfinder (vs OLED panel in other Sony models)
  • The absence of live view in continuous shooting rates of 8 or 10 fps makes correct panning extremely challenging.
  • The primary menu structure is difficult to traverse.
  • When using manual mode, aperture should be set in a manner that is counter-intuitive.
  • It is difficult to switch between the stills and the video playing modes.
  • Clear Image Zoom does not provide any improvements in image quality in comparison to post-capture upsampling.
  • In video mode, AF cannot be used in conjunction with manual exposure control.
  • Processing in JPEG that is below average, with soft details and noticeable imperfections.
