When it comes to DSLR cameras, the Sony Alpha a58 is an excellent choice since it combines outstanding photography capability with a range of sophisticated and intuitive features that help you obtain the best possible results for both still and moving images.
There are two sensors in the camera, one of which is an Exmor HD APS C sensor and the other of which is a BIONZ image processor, which works together to produce clear and detailed images with impressive low-light sensitivity up to ISO 16000 and fast performance that allows for up to 5 frames per second continuous shooting at high resolution.
The innovative Translucent Mirror Technology, which successfully directs light to both the image sensor and the focus sensor at the same time, is also a substantial benefit to the CPU and sensor combo.
Because of this, the 15-point autofocus system may continue to operate constantly even while recording video or photos in continuous shooting mode. In terms of video, the AVCHD version 2.0 format supports full HD 1920 x 1080 footage at up to 60i or 24p in the AVCHD 1920 x 1080 resolution.
When recording 1440 x 1080/30p videos, the Internet-friendly MP4 format is also accessible, allowing for a more streamlined and efficient process.
An electronic viewfinder and a rear LCD monitor are also included as part of the Translucent Mirror Technology for picture composition, playback, and menu navigation, in addition to a rear LCD display.
Because of the high resolution of the SVGA Tru-Finder OLED EVF (1,440k dots), you can see subjects clearly in real-time while using an eye-level viewfinder. Additionally, you can preview the impact of camera settings while using an eye-level viewfinder.
The back 2.7-liter engine “The 460.8k-dot Clear Photo LCD monitor has a tilting design that makes it extremely convenient to operate from both high and low angles, and the greater size is ideal for image review and editing.
A variety of imaging features have been integrated into the a58 to allow you to refine the overall look and feel of your images. These features help you to get ideal exposure results while also applying creative effects to your images.
Auto HDR works to increase the dynamic range of a single exposure by blending three distinct exposures-one overexposed, one neutrally exposed, and one underexposed-into a single picture to capture the most tonal detail possible.
Both Hand-held Twilight and Multi-Frame NR are designed to enhance hand-held shooting capabilities while also providing noise reduction procedures to help in shooting in low-light circumstances. When dealing with portraits and still lifes, Auto Object Framing and Auto Portrait Framing are used to automatically construct visually acceptable compositions based on the rule of thirds from source photographs.
They make use of a system of sophisticated detection and exposure methods to crop and enhance the appearance of photography, resulting in the creation of a new image that is both compositionally and tonally balanced in addition to the image that was originally captured.
The Sony DT 18-55mm f/3.5-5.6 SAM II lens is also included with the a58 digital camera, and it has a 35mm-equivalent focal length range of 27-82.5mm, allowing you to capture anything from wide-angle to portrait-length views.
This lens is equipped with the SAM (Smooth Autofocus Motor), which provides rapid and silent autofocus performance, and is beneficial for video recording and subject tracking. Several aspherical elements and one ED (extra-low dispersion) glass elements are used in the lens design to assist decrease chromatic aberration across the zoom range while also producing crisper pictures.
Exmor HD APS CMOS sensor with a 20.1MP resolution and a BIONZ image processor
APS-C-sized Exmor HD CMOS sensor with 20.1MP resolution and ISO sensitivity up to 16000 delivers high-quality images with excellent low-light sensitivity thanks to superior noise reduction technology.
Besides improving image quality, the BIONZ image processor also increases the overall speed and performance of the camera system, allowing for rapid full-resolution continuous shooting at a rate of 5 frames per second.
Translucent Mirror Technology is a term used to describe a type of transparent mirror.
This innovative design allows the mirror to continually guide light to both image and autofocus sensors, allowing for continuous phase- and contrast-detection focusing for speedy and precise performance. Translucent Mirror Technology is available in a variety of sizes and configurations.
A number of shooting features are aided by the reduction in camera speed gained by eliminating the need for a swinging mirror, including the fast continuous shooting rate, continuous focusing when shooting movies, and working in continuous shooting modes.
The camera also benefits from the use of a high-resolution electronic viewfinder for real-time monitoring at eye level.
Autofocus with 15 points of continuous coverage
The autofocus mechanism is able to continually monitor the image frame and adjust the focus swiftly and responsively due to the use of Translucent Mirror Technology. It is particularly handy when a crucial focus is required during video recording or when filming in continuous mode.
Focus placement is accomplished with high precision and speeds thanks to the utilization of 15 points, which include three cross-type sensors, in the camera.
It also collaborates with subject recognition technologies to give improved focus tracking, which can lock onto subjects and keep focus even when the subject is moving around inside the frame.
Sony DT 18-55mm f/3.5-5.6 G Master Lens SAM II Telephoto Zoom Lens
Although the integrated 18-55mm f/3.5-5.6 lens has a 35mm-equivalent focal length range of 27-82.5mm, it is compact and lightweight, making it perfect for usage in a broad range of photography conditions.
The SAM (Smooth Autofocus Motor) embedded inside the camera enables silent, rapid, and precise focusing that is ideal for video applications and following moving subjects.
Also included is a revised rear element shade, which helps to reduce internal surface reflections, as well as flare and ghosting, in order to provide images that are crisp and contrast-rich in color and contrast.
Tilting LCD Monitor with OLED EVF and Touchscreen
To watch the live view in real-time, perform picture review and playback, and navigate the menu system, two different viewing modes are available: a high-resolution electronic viewfinder or a big rear LCD panel.
The SVGA Tru-Finder OLED EVF has a bright and crisp 1,440k-dot resolution and delivers 100 percent frame coverage for perfect compositional correctness. It is also available in black and white.
For more comfortable viewing possibilities, the finder has the adjustable magnification and eye-point settings, and the eye-level viewing position can also be used as an additional point of contact between the photographer and the camera, which can help to increase stability when shooting with longer lenses or in low-light conditions.
The back 2.7-liter engine “The 460.8k-dot Clear Photo LCD monitor provides a bigger medium for viewing and producing pictures than the previous generation.
It has a tilting design that allows it to be rotated 135 degrees upward and 55 degrees downward, making it easier to see when working at high and low angles, respectively.
Full-HD video recording is available.
In the high-quality AVCHD version 2.0 format, full HD 1920 x 1080 video recording is available in both 60i and 24p frame rates at 60i and 24p frame rates. Translucent Mirror Technology allows for full-time live view monitoring as well as continuous focusing while recording, resulting in higher precision and guaranteed sharpness for the photographer.
Additionally, while filming for the web, it is possible to record at 1080/30p in the MP4 format, which allows for a more streamlined process.
Image Stabilization INSIDE the Camera Using SteadyShot
In-camera image stabilization, SteadyShot INSIDE is a sensor-shift type system that helps to decrease the impression of camera shake by up to the equivalent of 2-4.5 shutter speed steps, resulting in a sharper, clearer picture.
Sony’s SteadyShot INSIDE is available in certain Sony cameras. Because the image stabilization mechanism is integrated inside the camera body, any A-mount lens that is compatible with the a58 may be used in combination with the camera to benefit from the image stabilization system.
Auto Object and Portrait Framing is a feature in Photoshop.
Portrait and still-life compositions are automatically created by the Auto Portrait Framing and Auto Object Framing modes, which aesthetically crop your images based on the rule of thirds, the subject’s location within the frame, and exposure on your subject, and in the case of portraiture, the direction your subject is looking.
Using the Auto Portrait Framing mode in conjunction with the Face Detection, Smile Shutter, and Face Recognition modes, you may create great portraits in a very short amount of time. It is possible to output cropped photographs with complete detail and clarity using the iAuto and By Pixel Super Resolution technologies, which are applied in both modes to produce cropped images with ideal exposure balance that are reliant on the newly-created composition.
Both modes preserve the cropped picture with the original, unedited photo and can be used to create composite images.
Auto High Dynamic Range
During the use of this mode, three distinct bracketed exposures are taken at the same time and then automatically combined into a single file. Consequently, this file contains a greater variety of tones in the highlights, mid-tones, and shadows than would be achievable with a single exposure alone.
Because it does not necessitate the use of a tripod, this mode is more convenient than standard high dynamic range capture because it reduces the entire process to a simple in-camera function.
Multi Frame NR and Hand-Held Twilight are two examples of this.
Multi Frame NR and Hand-held Twilight, which are conceptually similar to HDR pictures, are both equipped with noise reduction technology that automatically merges six separate photographs into a single file, resulting in a decrease in the noise of up to two ISO levels (to an equivalent of ISO 25600).
These settings also provide you the option to shoot handheld exposures with little picture blur since six discrete exposures are taken at quicker shutter speeds than one long exposure, allowing you to capture sharper images.
Effects on Photographs
A wide range of visual effects is offered for in-camera image processing as well as for creative applications such as video editing. Posterization (both in color and in black and white), Pop Color, Retro Photo, Partial Color (R, G, B, Y), High Contrast Monochrome, Toy Camera, Soft High-Key, Soft Focus, HDR Painting, Rich-Tone Monochrome, and Miniature are some of the effects you may use.
