Sony SLT Alpha A55 Price in US

Not just for Sony but also for the enthusiast photography market as a whole, Sony’s most recent interchangeable lens cameras, the SLT Alpha A33 and A55, represent a significant technical milestone. These cameras are part of the SLT Alpha series.

In place of the conventional design of a DSLR, the business has developed a hybrid that, similar to a compact camera, is built from the bottom up around live view, but which is also capable of giving full-time phase-detection focusing similar to that of a DSLR. Because of the combination, they are now in a position to provide capabilities that were previously unimaginable at this price point. These capabilities include the ability to use phase-detection AF while recording movies as well as extremely fast continuous shooting rates (10 frames per second on the A55).

This is made feasible by adopting a method that has more in common with a mirrorless camera (like the Panasonic G2, for example) than with an SLR by eliminating the components that very much identify such cameras, namely the optical viewfinder and the moving mirror.

The term “SLT” means for “single lens translucent,” and the word “translucent” is the distinguishing factor that sets these new models apart from both traditional DSLRs and mirrorless interchangeable lens cameras. The term “SLT” stands for “single lens translucent.” The SLTs do, in fact, include mirrors; however, these mirrors are designed in such a manner that they enable the vast majority of light to travel directly through to the sensor without needing to be moved out of the way to facilitate exposure. As a consequence of this, they are constantly in the same place, reflecting a part of the light that is emanating from the rear of the lens onto an autofocus phase detection array that is placed in the top of the camera. (In the case of these two cameras, a recently designed 15-point array.)

The NEX-3 and NEX-5 all use the same 14 million APS HD CMOS sensor as the A33, however the sensor in the A55 is totally new and has 16.2 million effective pixels, making it Sony’s highest-resolution APS-C format sensor to date. The A33 has the same sensor as the NEX-3 and NEX-5. Both of these cameras are capable of recording video files at a quality of 1080p Full High Definition, which is another first for Sony’s large-body interchangeable lens models. Technically, this evaluation was carried out using an SLT A55V, which is the GPS-enabled edition of the camera that will be sold in the majority of nations. A non-GPS version of the A55 will only be available in a select few countries, the most notable of which being Japan.

8Expert Score
Good

The Sony SLT-A55 is a versatile camera that excels in all aspects and is equipped with a full complement of features. It features a novel touch thanks to the transparent mirror technology, which also provides the greatest live view AF available on the market. The performance in terms of continuous shooting is the finest in its category; nevertheless, you shouldn’t plan on using it to photograph the Olympics.

Pros
  • Very tiny design
  • The automated switch works really well and the LCD and EVF are both very decent.
  • Auto+ mode makes the different continuous shooting modes (see above) available to beginners
  • Very useful manual focus mode (including up to 15x image magnification)
  • Built-in GPS helpful for sorting photographs (albeit it sometimes struggle in built-up regions) (though it can struggle in built-up areas)
  • Lots of amazing features – 10fps, Auto HDR, Multi-shot NR etc., (automatically selected in Auto+ mode)
  • Screen that can swivel, which is handy for shooting from above and on video
  • System for the effective stabilization of images
  • A dynamic range that is nearly 9 EV, which is really impressive.
  • Versatile and competent (for its class) (for its class) 15-point AF system
  • Excellent digital level gauge in EVF/LCD
  • Solid ergonomics all over, good build quality, pleasant handling
  • Very Good JPEG resolution
  • Good quality HD video output
  • Useful Fn menu offers fast access to many key settings
  • Meticulous metering and sharp focusing
  • JPEG output with a high ISO that may be used up to ISO 12800 for smaller prints
  • Reliably good image quality at lower sensitivities
Cons
  • Control is restricted in the 10fps and movie modes.
  • When shooting at 10 or 6 frames per second, there is no live view, which makes panning nearly difficult.
  • Loss of detail is noticeable at any ISO setting higher than 400 when using the JPEG compression format (noise reduction too strong)
  • There are several scenarios in which 'ghosting' can be a problem (clipped specular highlights against dark backgrounds)
  • The menu system can be a little bewildering (hard to orientate yourself sometimes)
  • Slow (50 seconds) Clearing of the buffers (RAW-mode)
  • JPEG mode offers nothing in the way of flexibility over noise reduction at high ISOs ('auto' or 'weak').
  • EVF is somewhat more susceptible to RGB tearing than its competitors.
  • Unfortunately, the AF system is not nearly capable of catching quick activity.
  • It is difficult to switch between the stills and the video playing modes.
  • LCD particularly prone to finger prints and smearing (limiting visibility in very strong light) (reducing visibility in very bright light)
  • Image evaluation cannot be configured independently for the EVF and LCD displays.
