The Sony ALPHA 7 III: An entry point into mirrorless cameras

Move over, DSLRs: mirrorless cameras are the cool kid on the block, so now’s a good time to give them a whirl. The reviews of the Sony ALPHA 7 III are in—and it’s the perfect place to start.

What is a mirrorless camera?

Time to get technical: put simply, a mirrorless camera’s sensor is directly exposed to the light, with the image appearing on an electronic viewfinder (EVF). By contrast, a DSLR has an integrated mirror that bounces the light into the sensor and the viewfinder. The benefits of mirrorless are multiple: for starters, the EVF presents a “live” view of what the lens is seeing, so you can make rapid adjustments to the settings. It’s also more stable, making the image quality clearer. Lastly, it offers a higher shooting speed, and is more compact and lightweight overall—good for your back if you’re carrying it around with you.

The Sony ALPHA 7 III: the details

Is the Sony A7 III a professional camera? Not exactly. Marketed as an entry-level mirrorless model, it boasts fewer megapixels (24) and isn’t as fast at shooting as the Sony A7R III or A9, though it can handle weddings, wildlife photography and casual filming. Does that mean the Sony A7 III is good for beginners? Absolutely. With superb features, strong resolution and in-body image stabilization, it’s a great place to start if you’re new to full-frame cameras or if you’re looking to upgrade your DSLR. There are plenty of Sony A7 III lenses to choose from, too. Can the Sony A7 III connect to Wi-Fi? It sure can, along with Bluetooth and NFC. One final important question: does the Sony A7 III have autofocus? Yes it does, thankfully.
