If there’s one thing you can say about Sony’s digital camera business, let it be that they’ve tried their hand at a wide variety of various approaches and ideas. Sony has explored practically every option there is to explore in digital imaging, from single-lens reflex cameras with dual focusing systems and “Translucent Mirror Technology” to their NEX mirrorless line-up of cameras. It is possible that Sony’s most recent products, the Alpha 7 and Alpha 7R, are the most intriguing devices to emerge from the company’s research and development facilities in recent memory. The business has developed full-frame cameras that are almost the same size as the Olympus OM-D E-M1, which is quite an accomplishment. This means that the Alpha 7s are far more compact than other full-frame interchangeable lens cameras, such as the Nikon D610 and the Canon EOS 6D. This feat is largely made possible by the fact that the Alpha 7s are not single-lens reflex cameras.
In addition, Sony is combining the Alpha and NEX names, which means that from this point on, any and all future cameras that support interchangeable lenses will be classified as Alpha models. Because it lacks a mirror, the a7 probably would have been given the prefix NEX if it hadn’t already been taken.

The primary distinctions between the Sony a7 and a7R are the image sensor and the focusing technology; the two cameras’ exterior designs are otherwise similar. The a7 has a CMOS sensor with 24 megapixels and a full-frame resolution, whilst the a7R has a CMOS sensor with 36 megapixels and no optical low-pass filter. In contrast to the more conventional contrast detection utilized by the a7R, the a7 utilizes a hybrid autofocus technology (with on-chip phase detection) that is analogous to the one found in the NEX-6. The A7R does not have this feature, although the A7 can use electronic first curtain mode, which results in a quieter shutter and lowers the possibility of vibration caused by “shutter shock.” The A7R does not have this feature. Both cameras are equipped with the most recent version of Sony’s Bionz X processor, as well as XGA electronic viewfinders, tilting LCDs, Wi-Fi, and waterproof casings that are similar to those found on the Olympus E-M1.
To take use of the full-frame sensors, Sony needed to develop new lenses, which will be known as the ‘FE-series’ lenses when they are released. This is something that you would anticipate. The first announcement included the release of five lenses, which are detailed further down in the following list. The picture will (of necessity) be cropped when using lenses designed for the E-mount already in existence. If you already have lenses with an A-mount, you may use those as well as long as you purchase one of Sony’s full-frame-ready adapters (the LA-EA3 or LA-EA4).
The most recent iteration of the business’s processors, which has been given the name Bionz X for reasons that apparently make sense to someone, is noticeably more powerful than the generation that came before it, which the company claims enables it to do more complex processing.
To get the most out of the a7’s full-frame sensor, you won’t be able to use any of the lenses that are compatible with its E-mount. Instead, you’ll have to utilize Sony’s more recent FE-series lenses. The existing E-mount lenses will still be able to be physically attached to the camera, but because they are only intended for use with APS-C sensors, the image circles that they produce won’t properly cover the entire frame (this is analogous to using Sony’s DT lenses on full-frame Alpha mount cameras). Although the debut of the a7 was accompanied by the announcement of five FE lenses, only four of those lenses were available at “press time,” and the 28-70mm F3.5-5.6 OSS was included exclusively in a bundle with the a7. The prime lenses do not have optical stabilization, although the zoom lenses have. However, all of the lenses have been sealed against the elements.

The Alpha 7 has established new standards in the full-frame industry in terms of both its physical dimensions and its cost. The Sony Alpha 7 isn’t flawless, but its small size, extensive feature set, and excellent raw image quality more than make up for its flaws, which include rather short battery life and JPEGs that have been overprocessed to a small degree.
- Full-frame body that is compact and affordably priced
- Build quality that is rock-solid
- Well-implemented dual-axis electronic level
- Ports for both microphones and headphones
- Exposure compensation dial makes Auto ISO useable in manual mode
- The HDR and Sweep Panorama functions that are synonymous with Sony cameras perform admirably.
- It may be more convenient to charge via USB.
- A reliable Wi-Fi system enables distant shooting and makes it simple to share photos
- NFC is a bonus.
- LCDs that tilt provide excellent resolution and visibility even in bright sunlight.
- Powerful video capabilities including: manual settings, audio level adjustment, and uncompressed HDMI output.
- Excellent video quality overall.
- Instruments that are helpful, such as concentration peaking and zebra patterning (work well with native lenses)
- Adaptable hold for a battery
- Viewfinder electronic with a large size and a good resolution
- It is compatible with a wide variety of older 35mm camera lenses and there is no crop to the field of vision.
- When shooting in Raw, the image quality is quite high.
- Not equipped with a built-in flash
- A low level of JPEG quality in comparison to that of competitors, with crude sharpening, too aggressive processing, and occasional posterization.
- Autofocus may be difficult to use, particularly in low light
- AF performance improves when the assist lighting is switched off Auto ISO has a tendency to maintain the shutter speed at 1/60 of a second, which frequently results in fuzzy photographs.
- Tools for shooting with third party lenses have need for development. There is a restricted range of FE lenses, which are more expensive than those of the competitors.
- Start-up times that are significantly longer than the norm
- Overly sensitive eye sensor (also stays active when screen is tilted)
- After continuous shooting, the camera will 'lock up' while the buffer is being cleared.
- A short lifespan for the battery
- There is not an external charger supplied for either speedy charging or maintaining a fully charged backup battery.
- Poor menu organization, and navigating might be a touch clumsy at times (requires a lot of button-pressing)
- It's far too simple to accidently bump the exposure compensation and the back scroll wheel.
- The included software for remote capture does not include a live preview.
- There is no Raw conversion done in-camera.
