The A58 was introduced by Sony in February 2013. It belongs to the Amateur DSLRs category.
Sony is well-known and shouldn't require further introduction, please see our manufacturer's page for more digital cameras by Sony.
The A58 features a CMOS sensor in APS-C size that has an area of approximately 23 x 15 mm² (0.91" x 0.61").
This infographic compares the A58's sensor to other common formats:
(The 1-Euro coin used for scale has a diameter of 23.25mm, slightly smaller than a US quarter.)
Note: APS-C sensors made by Sony are slightly larger than those from other manufacturers.
The A58's image sensor has an effective resolution of around 20 megapixel. The resolution is above average and will be sufficient for the foreseeable future. Photos with this resolution can easily be printed in A2 size or larger, even if unwanted parts of the photo have to be cropped.
The Sony supports taking images in RAW. RAW images are stored as they come from the sensor, without any in-camera processing or sharpening. Converting to JPEG or other formats takes place on the computer, using software like Adobe Lightroom or Sony's RAW converter. This involves one extra processing step but almost always results in superior image quality. Some filters, like converting to monochrome (black and white) will only yield decent results when used with RAW images.
The A58 does not have a mechanism for automatic sensor cleaning. Dust that collects on the sensor has to be removed with a blower or brush.
|Sensor area||23.20 x 15.40mm²|
(0.91" x 0.61")
|Resolution (physical)||20.40 megapixel|
|Resolution (effective)||20.10 megapixel|
|Pixel size||18.08 µm²|
All compatible A Mount lenses can be mounted to the A58.
Currently, approximately circa 45 A Mount lenses are available, not counting lenses by third-party manufacturers. Further lenses can be connected via suitable adapters.

The A58 uses an electronic viewfinder with a resolution of 1.44 megapixel, an above average value for a viewfinder like this.The magnifcation is c. 0.53x, an average value for an electronic viewfinder.
The infographic illustrates the viewfinder magnification of the A58. The black area represents a magnification of 1x, corresponding to natural size. The red frame indicates the largest viewfinder magnification in any digital camera on the market today (0.85x).
Tip: If the viewfinder image of the A58 is fuzzy, us the little wheel next to the viewfinder to adjust the sharpness.
The A58's shutter speeds range from 1/4000s to 30s.
|Max. shutter speed||1/4000s|
|Min. shutter speed||30s|
The A58's sensitivity goes from 100 ISO und 16000 ISO, a very useful and practical range.
|Min. sensitivity||100 ISO|
|Max. sensitivity||16000 ISO|
The A58 supports all common metering modes.
The Sony will also allow spot metering, a must for challenging motives.
The A58's auto focus processor uses 15 AF points (or sensors). A basic rule of thumb says that the more AF points you have, the better. More AF points mean a better chance to have a point at the location of interest in a scene, a big plus in challenging situations (e.g. when doing macross).
Manual focus is also possible with the Sony, a plus in tricky situations or for some creative freedom.
The A58 features a built-in flash with a range of up to 10m (33 ft.). That range will work for most situations.
A flash or a trigger for remote flashes can be attached to the Sony's hotshoe. Very useful for indirect flashes or for trigggering remote flashes.
The A58 features a monitor with a diagonal of 67.00mm (2.6 in.) and a resolution of c. 0.46 megapixel. That rather low resolution is no longer state of the art and will make it difficult to evaluate images on the display.
The camera's display is articulated, a plus for selfies and other challenging situations.
The A58 does not feature a touch screen.
Display characteristics at a glance:
When recording videos with the A58, the highest supported resolution is 1920 x 1080 pixel, in other words Full HD Video. 4K videos are not supported by the Sony.
A connector for an external microphone is missing from the Sony. A built-in mike will usually record everything in front and to the sides of the camera which is not always what the film maker wants. Internal microphones also tend to record camera sounds like focus beeps.

Memory Stick Pro Duo
Memory Stick Micro
Let's have a look at some other features of the Sony A58:
The A58 doesn't have a built-in GPS receiver. If you want to add coordinates to your photos, you'll have to do so in 3rd party software like Adobe Lightroom.
The A58 features a built-in stabilizer. A plus when using legacy zooms or tele lenses without stabilizer.
The camera has a built-in function to facilitate creating panoramas: While panning the Sony over the scene, the camera takes a sequence of images which are then automatically assembled to form a panorama.
If you are into HDRs, the camera won't create those automatically. You will have to manually create image sequences and later assemble those sequnces in third-party software.
The A58 is not environmentally sealed against dust and moisture; keep that in mind in the rain and on the beach.
The Sony's features in a handy table:
The Sony A58 works with a NP-FM500H LiIon battery. The battery lifetime is a generous 700 shots. Usually enough for a full day or more.
The battery can not be charged while in camera. Instead you have to take it out of the camera and put it into the supplied dedicated charger.

|Battery life||700 photos|
The Sony A58's dimensions are 128.6 x 95.5 x 77.7mm³. (5.1" x 3.8" x 3.1"). That's the body only, without lens. The camera's weight is a reasonable 492 grams (15.9 oz.). Add to this the weight of the lens.
Front and top view of the A58 with dimensions:
To put the size of the camera in context, here it is next to a typical ID card (c. 86mm x 55mm, about the size of a credit card).
The A58 is clearly bigger:
