I got my first taste of this camera back at a Sony event held at the Museum of Natural History in New York City. The event wasn’t strictly about photography, but they were showcasing some of their newest cameras. I sketched my first impression of the camera after my few hours with it, and a few months later, I had it in my possession for a month. With 20.1MP, an APS HD CMOS censor, and smooth contours, the a58 can take some fantastic photos. I took it out alongside my a580, the a58’s portly older brother. As time progressed, I found that I warmed up to this camera, more so than I did initially.
Pros and Cons
Pros
-Excellent image quality
-Smooth form factor
-Great companion camera
Cons
-EVF is difficult to deal with in low light
-The AEL and AV buttons have switched with the SLT-line (a minor con, but it caused some confusion)
Gear Used
I used the Sony a58 with the Minolta 50mm AF f/1.7 and the Samyang 85mm f/1.4.

Ergonomics
I covered the ergonomics in the first impression, but I’ll reiterate them briefly here.
As stated previously, the a58’s SLT technology affords it the smaller form factor. With no reflecting mirror and no pentaprism to worry about, the a58 gets to be a bit smaller than its three digit OVF ancestors.
Up on top, you’ve got the mode dial with the standard P, S, A and M modes. Going clockwise from M, there’s Movie, Tele-zoom continuous priority AE, Picture Effect, Sweep Panorama, Scene, Flash off, Intelligent Auto and Superior Auto. To the right, you’ve got the on/off toggle, shutter release, ISO, Zoom, and Finder/LCD buttons.
Around back, there’s the menu button to the top left. Moving along, there’s the movie, AEL, and AV buttons along the top. To the right of the LCD, there’s the Fn, AF, Playback, and ?/Trash buttons. The AF is surrounded by the Display, White Balance, Picture Effect, and Self Timer.
My major point of comparison is my a580 which, when held against the a58, has hard lines instead of smooth contours. The a580 looks as if it was assembled from disparate parts on an assembly line whereas the a58 looks like it was fashioned from one piece. A nice touch on the a58 is the rubber grip that has a trigger bump separating the middle finger from the ring and pinky fingers.
Here’s a clearer view of the a58’s smooth contours against the a580’s defined lines.
Build Quality
The a58 is built from the same hard plastic as the a580 with a texturized grip and a smaller form factor. The a58 is visually appealing, more so than the a580. Mind you, I’m not structuring this as a comparison, but more so as a study to show how Sony’s Alpha design has evolved over the years. The a58 is sturdy and tight, and it makes for a great camera on the go. A major plus is that it takes the same battery from its alpha ancestors. It would be a solid choice, both in construction and performance, for those just entering the DSLR market.
Autofocus
In the best light, the autofocus is wonderfully fast. There are three autofocus modes: Single Shot, Automatic, and Continuous. I typically had it set to Single Shot as I’m not much of a burst shooter. There are four options for AF area: Wide, Zone, Spot, and Local. I tended to do local as I like the option to select my AF point.
It lagged a bit in low light, but not so much where you’d throw up your arms in frustration.
Ease of Use
If you have experience with Sony’s Alpha line, the a58 will be a cinch. Just mind the change in location of the AEL and AV buttons. If you’re coming from an older class of alpha, you’ll find yourself pressing the AEL button more times than you’d like. If you’re new to the Alpha family, the a58 will be a great learning tool. Everything’s fairly self explanatory, easy to locate, and well spaced. The design is comfortable for most mitts, and despite its smaller size than previous models, I had no trouble getting used to it.
Metering
The camera meters perfectly according to Sunny 16 standards.
Image Quality
The Sony a58 can create some truly stunning images that work nicely in Lightroom. The colors pop, and skin tones are rendered beautifully. This is a great choice for portraitists, and I used it for a headshot session with an actor friend (one of the photos comes later on). The sensor packs a punch, and it will do wonderful things for a photographer just starting out, and given what it can produce, it will make for a great secondary camera to your main rig.
Minor tweaks were done in Lightroom 4.
RAW File Versatility
The a58 renders fairly massive RAW files, 20.1 MP a piece. Hopefully, you’ll have a fast enough card because if you try to preview them in camera immediately after shooting, you’ll be met with a red light. There’s a lot of information to work with, and you can recover a good deal in Lightroom. In the first impression, I mentioned that this camera is being marketed as “an ideal choice for consumers eager to explore the world of DSLR-style interchangeable lens technology”. This puts it as an entry level camera, and those just starting out may not have a steady grip on the power of RAW files. Should they use the a58 as learning tool, however, they’ll find that they have a lot to work with, which is definitely a boon for Sony’s efforts here.
High ISO Images
I didn’t have the a58 in very many situations where I need to crank up the ISO, but I did it it out for a spin in an abandoned anthracite factory. There was a moment where I positioned the camera in a hole in the floor to take a photo of some sodas resting at the bottom.
ISO 3200 doesn’t seem to be ideal, but it’s passable should you absolutely have to use it.
Extra Image Samples
Conclusion
The a58 makes for a wonderful companion camera, or a great starting point if you’re just breaking into the DSLR realm. With an appealing design and intuitive layout (both the buttons and the menu system), it makes for a solid choice for anyone really. It should also be said that you have to be willing to break from optical viewfinders as Sony has abandoned the form in favor of EVFs and its SLT (Single Lens Translucent) technology. It can get a bit noisy in poorly lit situations, but it can do wonders in bright light. I’m a bit of a curmudgeon when it comes to viewfinders, but I found that I had warmed up to it, if ever so slightly. I still prefer my a580, the last of its kind in Sony’s alpha line, but the times have changed, and the a58 is like a slimmer, spunkier younger brother.
It’s $549 at Adorama and Amazon. That’s a great price for a great camera.
