Summary: My review of the Sony Alpha SLT-A55V DSLR camera can be summed up pretty easily: This is one of the best entry-level DSLR cameras currently available on the market.
The Alpha SLT-A55V -- usually called the a55 -- provides a very nice mixture of easy-to-use features and great performance, including great image quality and fast response times in all typical shooting conditions.
Pros: Extremely sharp and bright images, either in auto or manual shooting modes, Automatic exposure is very accurate, even in tough shooting conditions, Extremely easy to use for a DSLR camera; automatic shooting mode works very well, Autofocus is very fast and accurate, Camera automatically switches between viewfinder and LCD view, depending on how you're holding it
Cons: Camera's size may bother those used to a point and shoot camera, In extreme low-light conditions, camera sometimes cannot generate enough light to focus, Occasional glare makes LCD tough to see in direct sunlight, Might not have enough features for experienced photographers
Summary: The Sony Alpha SLT-A55 is an excellent alternative to a DSLR, acquiring most of their advantages, some unique abilities with very little downsides. Externally, the SLT-A55 is a lot like an entry-level DSLR, with a price to match. Its design though, which includes a translucent mirror, lets it perform phase-detect AF during exposures and video. No other ILC can shoot 1080p video while focusing so quickly.
Pros: Good resolution and sharpness, Lower than average image noise, Good color accuracy, Conservative metering, Speedy and accurate autofocus, Very effective image stabilization, Excellent large and detailed EVF, True exposure-priority Live-View, Fantastic Eye-Start sensor, Phase-Detect AF-C while recording video, AF-C during continuous drive up to 10 FPS, Excellent dual-axis digital-level, Fast and responsive, Nice build quality, Good ergonomics, protruding EVF, Phase-Det...
Cons: High-ISO softness due to, AWB struggles more than usual, Indistinct EC button, Tiny video crop-marks, 1s Delay starting video recording, 1s Delay stopping video recording, Eye-Start AF triggers too often, Delicate translucent mirror, Gap below mirror lets dust in, No way to use 1/2 EV stops, Histogram and level views show little info, Difficult Sweep Panorama framing, GPS not so reliable, Weak LCD hinge
Conclusion: The Sony Alpha SLT-A55 is an impressive piece of kit. It's well made, offers a host of decent lenses, and is incredibly quick. It's good for shooting fast moving objects then, but you'll have to get used to the electronic viewfinder.
Pros: The Sony Alpha SLT-A55 is a fast camera – amazingly so at times. The main reason for this is the lack of movable mirrors inside the body. This means it's not a traditional DSLR – even though it features similar sensor technology and interchangeable lenses, and as a result you can capture up to 10 frames per second with the Sony Alpha SLT-A55. The lack of mirrors also allow the Sony Alpha SLT-A55 to be smaller than other Sony Alpha models; it's a lot more compact and l...
Cons: On the downside, the lack of moving mirrors inside the Sony Alpha SLT-A55 mean that what you see isn't exactly what you get. Instead of seeing through the lens itself, the Sony Alpha SLT-A55 uses an electronic viewfinder (EVF). It's good, but it uses more battery life than a proper viewfinder, and it can never quite match up to DSLR rivals.
Summary: As you have likely gathered by now, I think the Sony A55 is a great entry-level camera. Those who love the ability to frame photos using the live view display won’t find a more capable DSLR-type camera than the A55. And, if you are stepping up from a point and shoot camera, you’ll feel right at home with the A55′s user-friendly display and autofocus features.
Summary: Expensive and probably a bit large for the typical point-and-shoot upgrader, the Sony Alpha SLT-A55V nevertheless delivers the performance and photo quality boost those shooters are expecting.
Pros: Fast, especially for burst shooting; articulating display; relatively straightforward, streamlined interface; really nice virtual-level implementation.
Summary: The Sony SLT-A55 is an excellent all-rounder with a comprehensive feature set. The translucent mirror technology gives it an innovative touch and the best live view AF on the market. Continuous-shooting performance is the best in its class--just don't plan on shooting the Olympics with it.
Pros: Reliably good image quality at lower sensitivities, High ISO JPEG output usable up to ISO 12800 for smaller prints, Excellent LCD and good EVF, with efficient automatic switch., Versatile and capable (for its class) 15-point AF system, Accurate metering and focus, Very Good JPEG resolution, Very good (almost 9EV) dynamic range, Good quality HD video output, Swivel-screen useful for overhead- and video shooting, Good ergonomics all around, good build quality, nice hand...
Cons: Limited control in 10fps and movie modes, AF system not quite up to capturing fast action, No live view in 10fps/6fps shooting makes panning almost impossible, Slow (50 seconds) buffer clear time (RAW-mode), Little control over high ISO noise reduction in JPEG mode ('auto' or 'weak'), Visible loss of detail at anything over ISO 400 in JPEG mode (noise reduction too strong), Menu system a little confusing (hard to orientate yourself sometimes), 'Ghosting' can be an iss...
Conclusion: Given the current Sony A55 price, it may still prove to be a compelling choice if the features meet your buying criteria, due to its decent image quality at high sensitivities, compact dimensions and support for existing Sony A-mount lenses.
