Alpha NEX-7 Camera

Compact Camera Redefined

Get your hands on a camera that fits in your pocket or purse, but offers the quality and performance of one nearly twice its size - the Alpha NEX-7. It comes with a massive 24.3MP APS-C sensor and a through-the-lens OLED electronic viewfinder. Choose the perfect lens, then give the Tri-Navi™ dials a spin for instant manual control. Topped it off with Full HD video and up to 10 still frames per second, the NEX-7 delivers.


The camera is compact. The sensor is anything but. Bigger sensors equal better pictures. That's why the NEX-7 boasts a huge, 24.3MP APS-C sensor - the same size sensor used in most DSLRs for ultra-high resolution and incredibly - detailed photos that make for gorgeous enlargements. With a sensor 13 times larger than the average compact camera, the NEX-7 offers the image quality and performance of a DSLR in about half the size and weight.


The APS-C size sensor is more than 13 times larger than 1/2.4-size sensors, three times larger than Nikon CX format and 1.6 times larger than Micro Four Thirds sensors


10 Photos in One Second

Whether shooting a sequence of your preschooler's somersault, or the game-changing instant when ball meets bat, be sure you capture the most critical moments with up to 10fps continuous shooting at full 24.3MP resolution (exposure and focus fixed at the first frame). It's ideal for high-speed sports photography or capturing the fast, fleeting moments other cameras miss. Standard continuous shooting is also available at up to 2.5fps.


Make HD Movie Magic

Record crystal-clear HD movies in super-smooth 60p, standard 60i or richly-cinematic 24p - all at Full HD 1920 x 1080 resolution (records in 29-minute segments). Shoot in the industry-standard AVCHD™ codec for stunning fast-motion video with reduced distortion, or choose the web-friendly MP4 format for easy uploading to sites like YouTube™, Facebook®, and more.


Control at Your Fingertips

Looking for a quick and intuitive way to set aperture, exposure, ISO, and more - faster than ever? Three Tri-Navi control dials put everything at your fingertips. You see the results instantly through the viewfinder or on the camera's tiltable 3.0" LCD. It's perfect for experienced photographers who want immediate, hands-on access to up to three controls at once.


World's First OLED Viewfinder

The Tru-Finder™ OLED electronic viewfinder brings eye-level, through-the-lens viewing to the NEX-7. Boasting 2359K dots and a high contrast ratio for top resolution and unprecedented brightness, images pop with clarity and detail making it easier than ever to compose your shots. You can even see the results of camera adjustments in real time through the viewfinder.


Eye-Popping Picture Effects

Let your imagination run free with 11 in-camera creative effects. Transform ordinary portraits into colorful, high-contrast works of art with Pop Color. Get the tilt-shift photography look with Miniature effect. Try Toy Camera for a nostalgic, lo-fi feel, or make your focal point pop with Partial Color effect.


Interchangeable Lenses

Open up to a world of creativity by finding the perfect lens for practically any situation. Choose from a variety of interchangeable E-mount lenses created specifically for your NEX camera.


Unleash Your Creativity

When it comes to lenses, the more options the better. In addition to E-mount lens compatibility, an optional adapter (sold separately) lets you use Sony A-mount lenses and take full advantage of wide-angle shooting at the lens's designed focal length with no cropping.


PlayMemories Online

With PlayMemories Online, all of your photos and videos can finally be stored, accessed and neatly organized in one place - regardless which device they were taken with.
