Sony a77 Mirrorless Camera Review

Introducing the Sony Alpha SLT-A77 DSLR Digital Camera, which Sony hopes will pique your interest (Body Only). There are a number of positive aspects to this DSLR, not the least of which is the 24.3Mp sensor it has.

Consider all of the possibilities that a resolution of 24.3 megapixels provides: mural-sized prints, stunning detail, vibrant color, and much more! If you’ve been yearning for the pixel power of medium format photography, but in a DSLR format, your wait is now over.

Sony also equipped the A77 with their Translucent Mirror Technology system, which is the second generation. What exactly does this technique accomplish? In this mode, the camera can focus with the speed and precision of Phase Detection AF while also shooting at the same time.

As far as digital photography is concerned, this is a previously unheard-of capacity, at least up until now. The camera is also equipped with an updated BIONZ image processor from Sony. There are several jobs performed by the CPU, including the efficient transfer of shot data to the chip in your memory card.

Additionally, it lowers visual noise and guarantees that capabilities such as 6-image layering and 2D/3D Sweep Panorama operate smoothly and at the required speed, among others.

The SLT-A77 is more than just a still camera; it can also record high-definition AVCHD video at 60p or 24p at a resolution of 1920 x 1080p. You may also opt to record at 60 frames per second. Full manual control over the recording of HD movies is also possible.

That means you have access to every setting on the mode dial, including Program, Shutter Priority, Aperture Priority, and Manual. There are additional options for Live View and Full-Time Live View (in either the LCD or the EVF), as well as Full-Time Phase Detection AF.

It goes without saying that the latter is a clever method of automatically correcting focus while you remain focused on the scene in front of you.

What the DSLR also provides, in addition to the features found in most less-sophisticated cameras, is a viewfinder, which is how all of your heroes used to shoot back in the day. The A77’s OLED viewfinder allows you to take your gaze away from the LCD screen and into the proper position for taking good photographs.

This viewfinder, like other viewfinders, is designed to keep distractions and glare at bay. However, one of the things that the OLED viewfinder achieves that sets it apart from the competition is that it reduces motion blur on the Tru-Finder screen.

The OLED display has a resolution of 2359K dots and a contrast level of 5,000:1. You may also view the consequences of camera settings in real-time, with colors and detail that are as close to live as they possibly can be.

Of course, the SLT-A77 is equipped with an LCD panel as well, but it is not just any monitor. When it comes to capturing difficult photos or successfully analyzing film in low light settings, this one tilts and swivels to make it possible.

What more can you do with this sort of LCD display device? What do you think of self-portraits? Everyone knows you take them; every ‘artistic’ photographer does, after all!) Whenever it’s not in use, the screen may be folded flat against the camera for storage and transportation convenience.

As far as shooting performance is concerned, the A77 provides the types of features and functionalities that one would expect from a camera of this kind, especially when it comes to everything that is internal to the camera.

It is possible to capture up to 12 frames per second at full quality with this camera, which is excellent news for photographers who cover sporting events. In addition, the A77 has a very small lag time of approximately 0.05 seconds.

Then there’s the 16,000 ISO sensitivity and the 1200-zone exposure metering, which are also standard features. The metering feature takes its readings straight from the camera’s primary image sensor and provides three different metering options: Multi, Center, and Spot.

There is also a slew of other proprietary shooting options included with the camera. While you can shoot in manual mode, you may find yourself experimenting with all of the built-in choices for expressing your artistic side instead. First and foremost, there are the twin control dials, which allow you to access two different settings at the same time.

You’ll find all of the typical P, A, S, and M exposure options on the menu. By going into the menu functions, you’ll discover features such as a nineteen-point autofocus system, object tracking autofocus system, and six-image stacking, just to name a few. If you go a bit further, you’ll find that Handheld Twilight mode and Multi-Frame NR are also available to assist you in capturing outstanding low-light shots.

Aside from that, you’ll get accessories like a built-in GPS. Because the embedded GPS receiver records the position and time of every photo you take, you may view them on a map using compatible computers and Internet apps later on in the day.

This function is also useful for individuals who are interested in ‘geo-tagging.’ Eleven Picture Effects modes, including options such as Pop Color, Retro Photo, Toy Camera, and more, provide you with yet another method to express yourself creatively. Face recognition and Sony’s Smile Shutter technology, both of which are old standards, are still available for your usage.

Sony equipped the SLT-A77 with a built-in flash, just like every other high-quality DSLR worth its salt. This allows you to capture images in low light with ease. The same flash can also be used to activate an optional wireless flash if one is available. The camera also features an inbuilt hot shoe, which can be used to attach a variety of external flashes and flash accessories to the camera (sold separately).

Translucent Mirror Design for the Second Generation

Other DSLRs are capable of shooting. Alternatively, users can use the speed and precision of Phase Detection AF to focus. They are unable to perform both at the same time. Sony’s Translucent Mirror Technology technology, which has won several awards, alters all of that. In addition, it sends light to the image sensor and the Phase Detection Autofocus sensor at the same time.

Resolution: 24.3 Megapixels

With an APS-C sensor that captures 24.3 megapixels, you can capture stunning detail and beautiful enlargements.

Frame rates of up to 12 frames per second are possible. Continuous

When you have a transparent mirror, it is much simpler to record the winning soccer kick or your kid at her prettiest. Continuous autofocus allows for up to 12 frames per second at maximum quality (24.3 megapixels) when shooting in burst mode (AE locked after the first frame). As of August 2011, this is the world’s quickest shooting speed for interchangeable lens APS-C cameras, according to Canon.

OLED (Organic Light Emitting Diode) Viewfinder

In terms of electronic viewfinders, there has never been anything quite like the Tru-Finder OLED. This is a rare find in terms of size, speed, and brightness, even after sunset. It starts with 2359K dots for excellent resolution and a high contrast ratio for outstanding depth, and it goes from there.

The use of OLED technology lowers motion blur to the absolute minimum. In addition, you can view the outcomes of camera modifications in real-time, with stunning color and detailed reproduction.

HD movies in 60p, 60i, or 24p resolution

Capture breathtaking high-definition movies. In addition to shooting Full HD 1920 x 1080 resolution, this is the world’s first DSLR to provide a choice of super-smooth 60p video, regular 60i video, or cinematic 24p video. The AVCHD Progressive codec produces an image of exceptional quality. The MP4 codec compresses files to make them smaller, making them easier to post to the web.

HD Movies with Complete Control Over the Action

When shooting high-definition movies, you no longer have to give up control. In HD video mode, you may make use of the full expressive potential of Program, Shutter Priority, Aperture Priority, or Manual (P/A/S/M) control.

AF with full-time phase-detection and tracking

Because of Sony’s proprietary Translucent Mirror Technology, you enjoy quick, precise autofocus in any mode, including HD Movie and Live View. The difference between phase detection autofocus and contrast-detection autofocus is that phase detection autofocus knows precisely where the proper focus is and goes straight for it, whereas contrast-detection autofocus seeks for the correct focus.

Full-Time Live View on LCD or EVF is available.

When shooting in Live View, you may compose your photos using both the LCD panel and the OLED Electronic Viewfinder. In addition to providing a “what you see is what you get” preview of the camera’s settings such as white balance, focus, depth of field, exposure, and 100 percent framing accuracy, both include helpful on-screen displays.

Release Time Lag is a short period of time.

Assists in ensuring that the picture you desire is the one you receive. Once autofocus has been achieved, release time lag refers to the time elapsed between pressing the shutter release button all the way down and the camera actually starting to take the picture.

Fast-moving objects are more difficult to capture when there is a long latency. The Sony A65 has a small DSLR release time lag of approximately 0.05 seconds, which is impressive for a DSLR.

Magnesium Alloy Construction for Durability

The SLT-A77 is created for use in the real world, with a magnesium alloy body that is both strong and light, making it ideal for outdoor use. Ports, doors, and controls are also weather-resistant to ensure that they operate smoothly even under poor weather conditions.

Object Tracking AF (Automatic Object Tracking)

The subject is locked onto a certain object, and the focus is maintained even when the subject moves. Subjects that are unpredictable remain in focus even while zooming. You can concentrate on your composition without having to worry about your concentration.

Auto Focus with 19 points of detection

Sony’s Phase Detection Autofocus (AF) system is extremely sophisticated, allowing it to leverage the utility of Translucent Mirror Technology. Nineteen sensors, including eleven cross sensors, provide the highest level of accuracy for both vertical and horizontal topics.

LCD Display with Three-Way Tilt and Swivel

Tilt the camera up or down to capture high- and low-angle photos that would otherwise be difficult to capture. Self-portraits may be taken by tilting and swiveling the camera. It is even possible to tilt the camera up and down when the camera is in vertical mode! Once folded flush with the camera, the display may either be used for photography or kept covered for travel.

Control Dials with Two Positions

Dual control dials, which are ideal for experienced shooters, allow direct, hands-on access to two settings at the same time.

LCD display mounted on the top of the unit

Additionally, in addition to the status displays on the LCD monitor and the Electronic Viewfinder, Sony provides a top-mounted LCD that shows exposure data.

6-Image Stacking and Layering

This feature takes advantage of the fast BIONZ processor in order to record six photos in less than half a second and then aggregate the data. It produces an excellent single image that may be cleaned up in Multi-Frame NR mode or sharpened for evening photography in Hand-Held Twilight mode, depending on the setting selected.

Multi-Frame NR is a kind of noise reduction.

Without the use of a flash, you may capture fantastic low-light images. A fraction of a second is enough time for the camera to record six photographs. By combining the data from all six sensors, it is able to provide a single image with a decrease in noise compared to two more steps of exposure sensitivity. The sensitivity may be adjusted up to ISO 25600.

Twilight Mode for Handheld Devices

Without the use of a tripod, you may capture stunning nighttime images. For smooth, low-noise nighttime photographs, this feature combines six frames into a single image.

Auto HDR is pre-installed on the camera.

It captures a greater dynamic range in a scene than a single exposure can handle, and it captures a more dynamic range than a picture film. This photo combines the finest highlight detail from one shot with the best mid-tones from another and the best shadow detail from a third to create one stunning image.

Panorama Mode with 3D Sweep

Capture stunning 3D images of expansive landscapes and 16:9 aspect ratios. As you move your camera around the panorama, the camera records distinct right-eye and left-eye pictures, which are shown on your 3D screen to bring landscapes to life. It captures images in both JPEG and MPO file formats.

Sweep Panorama is a type of panorama mode that sweeps over the screen.

Capture large vistas in a simple and automated manner. Press the shutter button and sweep the camera vertically or horizontally. The remainder is taken care of by the camera, which continually captures photos and stitches them together.

GPS with built-in navigation

Each photo you take is recorded by an embedded GPS receiver, which displays your images on a map when used with compatible computer and Internet programs. This allows you to recall the place and time of each shot you take and helps you remember where you took your best shots.

Preview of the shot’s outcome

Take a look at the outcomes before you make your shot. This preview removes the guesswork from camera settings by demonstrating the impact of the aperture, shutter speed, and DRO settings on the depth of field, motion, and dynamic range of the image.

LCD Display with 921K Dots in TruBlack

The 921K dots on Sony’s 3.0 inch Xtra Fine LCD panel give it an exceptional resolution. The TruBlack screen has a unique resin coating that reduces internal reflections, resulting in increased contrast when compared to ordinary LCDs. Using the Sunny Weather setting increases visibility even further.

Main Sensor Live View with Quick AF

Incorporates the quick focus of phase-detection autofocus with high-quality Live View photos taken directly from the primary sensor to create a powerful combination.

Sony Translucent Mirror Technology is responsible for making this feasible. On the LCD monitor or the eye-level viewfinder, you receive sharp shots and perfect framing every time.

Temperature Sensitivity (ISO 16000)

Exmor APS HD CMOS image sensor with reduced noise and enhanced BIONZ image processing allows for very clear low-light photographs without compromising detail.

AUTO+ (Advanced Auto) Mode is available.

Improve the quality of your photos by making them more lively and taking fewer missed shots. Sony intelligent technologies are brought together and simplified. The camera automatically detects and selects the appropriate scene mode.

Display of Graphics

The link between aperture and shutter speed as well as the impact that each has on photography outcomes are explained in detail.

BIONZ Image Processor has been upgraded.

The BIONZ image processor from Sony, which has been significantly enhanced to meet the demands of 24.3-megapixel shooting, serves as the camera’s brain. Even at ISO 16000, chroma noise reduction allows for high-resolution, low-noise images to be captured.

Allows for up to 10 frames per second continuous shooting of data-intensive 24.3 MP photos, 3D Sweep Panorama modes, and 6-image stacking in addition to 24.3 MP image processing.

Dynamic Range Optimizer is a program that optimizes the range of a signal (DRO)

Improves the quality of results while shooting backlit subjects and reveals details that were previously concealed in shadows. Auto, Level (with a choice of five operating levels), and Off are all available options.

Exposure metering using 1200-zones

This function reads the exposure straight from the primary image sensor of the camera. A variety of metering options, including Multi, Center, and Spot, are available to handle a wide range of shooting conditions.

Stabilization INSIDE the camera using SteadyShot

In order to minimize blur, image stabilization compensates for camera vibration. Typical DSLR systems include image stabilization into just a few lenses at a time. Cameras with SteadyShot INSIDE image stabilization have the technology incorporated right into the body of the camera. The reduction of blur is achieved by the use of every A Mount lens, including macro and wide-aperture regular zoom lenses.

HDMI output for high-definition viewing

On a compatible HDTV, you may enjoy high-definition movies and breathtaking still photographs. The camera is equipped with an HDMI output. Aside from that, the BRAVIA Sync system works with Sony BRAVIA HDTVs that are compatible, allowing you to control camera playback via the television’s remote control.

Battery life of up to 530 shots is possible.

Sony Stamina battery power allows you to take up to 530 pictures on a single charge. Sony’s InfoLITHIUM battery technology allows you to view how much power is left in the battery at any time, allowing you to continue shooting with confidence.

Exposure Modes: P, A, S, and M

The camera has a comprehensive set of settings, ranging from the beginner-friendly AUTO+ mode through P/A/S/M, which stands for Program, Aperture Priority, Shutter Priority, and Manual. On-screen suggestions assist you in refining your abilities, increasing your self-confidence, and exercising greater creative freedom.

Anti-Dust Technology of the Highest Level

Anti-Dust Technology helps to keep the CMOS sensor clean, producing in images that are dependably crisp and clear. First and foremost, a static-free coating on the sensor’s low-pass filter aids in the repelling of dust. The vibrations then immediately remove any dust that has accumulated on the sensor.

Flash Memory Built-In (GN12)

The camera contains a built-in flash (Guide Number 12), which may also be used to activate a wireless accessory flash, to assist you in shooting more successfully (sold separately). A variety of auxiliary flashes may be attached to the built-in hot-shoe, allowing you to broaden your lighting options.

Two different media types are accommodated in this slot.

Memory Stick PRO Duo/Memory Stick PRO-HG Duo and SD/SDHC/SDXC media are both supported by the camera, allowing for cost-effective and simple storage and sharing of your photographs.

High-Definition CMOS Image Sensor in the APS-C Format

With an image sensor that is 19.5 times the size of a standard camcorder image sensor, the APS-C format distinguishes between amateur and professional-looking video by offering an unparalleled mix of high resolution, high sensitivity, and stunning, blurred backgrounds.

Exmor technology from Sony

Conventional image sensors make use of just a small number of analog-to-digital (A/D) converters, which might cause your computer to run slowly. It is estimated that the Exmor sensor has more than 5,600 column-parallel A/D converters. This makes it possible to shoot continuously at speeds of up to 10 frames per second.

There are 11 different picture effect modes.

Learn about new and imaginative methods to make your photographs and videos stand out. Posterization (color and black and white), Pop Color, Retro Photo, Partial Color (red, green, blue, and yellow), Soft High-Key, High Contrast Monochrome, Toy Camera, Soft Focus, HDR Painting, Rich-tone Monochrome, and Miniature are some of the techniques used in photography.

Detection and registration of human faces

A total of eight different faces may be detected by the camera, and the camera can automatically change the focus, exposure, white balance, and flash to assist create sharp, properly lit photographs of individuals. Can give preference to youngsters or adults. Face Registration can help you recall friends and family members and prioritize them in a crowded environment.

With the help of Smile Shutter Technology,

Captures a grin at the exact time it occurs. Simply pick the Smile Shutter option on the camera’s menu, and the camera will automatically capture the photo. You have the option of prioritizing children or adults, as well as adjusting the smile sensitivity.
