The Sony Alpha 57 ($699.99 direct, body only)£1999.99 at Amazon UK is one of four APS-C D-SLR cameras in Sony's current lineup. It's one step up from the entry-level Alpha 37, and like its siblings sports a fixed mirror design and an electronic viewfinder, a departure from classic SLR cameras that use a moving mirror and optical viewfinder for through-the-lens viewing. The 16-megapixel A57 is capable of producing some excellent images and delivers a superlative video recording experience, but its EVF is just not as good as the next model up in the Sony line, the Alpha 65£899.99 at Amazon UK, and the camera is a little slow to start and fire a shot. Nikon's more traditional D5100SEE IT remains our Editors' Choice for D-SLRs priced under $1,000.

Design and Features

At 3.9 by 5.25 by 3.25 inches and 1.4 pounds, the Alpha 57 is only slightly larger than the Nikon D3200SEE IT, which measures 3.8 by 5 by 3.1 inches, but is lighter at one pound. Its sharp 3-inch 921k-dot rear LCD is hinged so you can view it from the side, the top, or slightly above your head. It's also possible to disable the screen by facing it toward the camera, which is handy if you prefer to use the eye-level finder. By default the camera automatically toggles between the EVF and the rear LCD as you place the camera to your eye or pull it away, but you can disable this functionality and opt to use the physical Finder/LCD button to switch between the two.

The viewfinder is one of the most important ergonomic components of any SLR, and the Alpha 57's is a bit lacking. Even though its 1.4-megapixel resolution sounds impressive, it's not nearly as sharp and lacks contrast when compared with the 2.5-megapixel OLED EVF found in Sony's Alpha 65, Alpha 77, and Alpha NEX-7See it at Amazon UK cameras. If you're shooting in low light, the typically fluid finder suffers from laggy, stuttering motion.

Sony clearly put some thought into the Alpha 57's control layout. The camera has a mode dial on its top left side, a front control dial, and Exposure Compensation and ISO buttons on the top of the grip, directly behind the shutter and On/Off switch. The rear of the camera features buttons to control the Drive mode, White Balance, and Exposure Lock, and to start Movie recording. An overlay menu, which gives you access to the rest of the shooting controls, is launched by pressing the Function button. There's no rear control dial, which makes it challenging for shooters who are used to a dual-dial camera like the Pentax K-30See it at Amazon UK. Having a second dial available makes it easier to shoot in Manual mode, and to more quickly adjust a second shooting setting when using the camera in Aperture Priority or Shutter Priority mode.

My Experience

Images, and the devices that capture them, are my focus. I've covered cameras at PCMag for the past 14 years, which has given me a front row seat for the changeover from DSLRs to mirrorless cameras, the smartphone camera revolution, and the emergence of drones for aerial imaging. I have extensive experience with every major mirrorless and SLR system, and am also comfortable using point-and-shoot and action cameras. As a Part 107 Certified drone pilot, I’m licensed to fly unmanned aircraft systems (UAS) for commercial and editorial purposes, and am knowledgeable about federal rules and regulations regarding drones.

The Technology I Use

I use all of the major camera systems on a regular basis, swapping between Canon, Fujifilm, L-Mount, Micro Four Thirds, Nikon, and Sony systems. I still find time to use Leica M rangefinders and Pentax SLRs on occasion, too. I keep an iPhone 13 in my pocket for the rare occasions I'm not carrying a camera.

I'm not a brand-specific photographer. For product review photos, I swap between a Canon EOS R5 and a Sony a7R IV. I use Flashpoint and Godox TTL lights and Peak Design tripods, and I most often reach for a Think Tank or Peak Design backpack to carry equipment.

When it comes to computers, I'm an unapologetic Mac person and have been for the past 20 years. I write in Pages and use Numbers for spreadsheets. I currently swap between an Intel i9 MacBook Pro and an Apple Silicon Mac Studio for writing and use a calibrated BenQ 32.5-inch with the Studio for photo and video editing. I rely on a LaCie 6big RAID for media storage. I also keep a PC around for gaming, but please don't tell my Macs about it; they'll get jealous.

I split time between several different software apps depending on the type of editing I'm doing. For Raw image processing, Adobe Photoshop Lightroom Classic is my standard. I pair it with a LoupeDeck CT console to supplement my keyboard and trackpad, and I lean on RNI All Films 5 presets when I want to give an image a film look. I use Apple Final Cut Pro for video editing.

My first digital camera was the Canon PowerShot Elph S200, and my first DSLR was the Pentax *ist DL. I have a soft spot for antique film gear. I still use a 1950 vintage Rolleiflex Automat TLR and love trying mid-century Leica lenses on film and digital alike. I mainly use whatever's in front of me for review for digital snaps, but I pick up either my Leica M Typ 240 or Pentax K-3 III Monochrome when I want to step away from review work. In my downtime, I enjoy bird watching, reading, video games, and both good and bad movies, especially in the sci-fi and horror genres.
