Sony Alpha a7R III A Full-Frame Mirrorless Camera Body (ILCE7RM3A/B, New Version)

The Sony a7R III A achieves outstanding resolution, sensitivity, dynamic range, and provides the technical capability you need to let your imagination soar and fulfill your vision with breathtaking reality. The full-frame, mirrorless a7R III A will up your photography game without breaking the bank, and has a variety of connectivity features that offers the potential you need to explore worlds that have previously been beyond reach.

42.4 Effective Megapixel Full-Frame Exmor R CMOS Sensor

The Sony a7R III A features a back illumination for high sensitivity, gapless on-chip lenses, antireflective seal glass coating, no optical low-pass filter, and other unique features. The high resolution, high sensitivity with low noise and wide dynamic range add up to vastly expanded shooting potential.

High-Speed BIONZ X Image Processor

The BIONZ X image processing engine offers an increase in system speed, plus an impressive 15-stop dynamic range at low-sensitivity settings. Sony’s Detail Reproduction Technology has been updated with advances along with the Area-Specific Noise Reduction feature which can reduce noise by as much as a full stop in the mid sensitivity range. The combination of high resolution and low noise is ensured over a wide sensitivity range, for excellent image quality and color accuracy that is ideal for portraits and landscape photography.

Up to 10 fps with AF/AE Tracking

Thanks to the new shutter unit and image processing system refinements, the a7R III A is capable of shooting continuously at up to 10fps with AF/AE for easy, stable shooting of even intensely active subjects. An electronic shutter allows silent, vibration-free shooting when even slight noise can mean missing an ideal shot.

Advanced Autofocus

The a7R III A also autofocuses reliably down to EV-3 brightness. AF algorithms optimized for the a7R III A improve AF speed, precision, and tracking performance. 399 phase-detection AF points and 425 contrast-detection provide high-density wide-area coverage. The a7R III A also features Eye AF's enhanced precision, plus two times greater AF speed and AF tracking performance further assists you to easily shoot a portrait of a moving subject using AF-C even during continuous shooting. Focus information from the lens keeps AE control and image brightness consistent even when subject position or background brightness changes. The a7R III's E-mount body supports Eye AF for A-mount lenses mounted via an adaptor.

High-Resolution 4K HDR

The camera features a Hybrid Log-Gamma picture profile, supporting instant HDR workflow, that provides a wide dynamic range for highly precise and lifelike movie images without color grading.

Versatile Viewing

This high-resolution Quad-VGA OLED Tru-Finder has approximately 3.69 million dots. It provides outstanding details and high contrast for accurate black reproduction. The high luminance brings viewfinder brightness closer to that of the actual scene. The high quality of the viewfinder image and features like focus magnification make it easier to achieve perfect focus with just about any subject in any situation.

Wi-Fi and NFC Functionality

The Sony a7R III A offers a variety of controls and functions. With the one-touch remote, a smartphone or tablet functions as a viewfinder/remote control. You can easily share transfers photos/videos to the device with One-touch. Install the PlayMemories Mobile app on an NFC-enabled Android device via Wi-Fi. The Sony a7R III A provides features that will perfect and enhance your images. All of this comes in a compact package that is easy to use while seamlessly supporting professional workflows.

Rated 5 out of 5 by from Intuitive Camera Out of the Box I have only shot on Canon products. Out of the Box it makes me want to get rid of all my Canon gear.

Rated 5 out of 5 by from Best beginners camera Awesome Camera.My first dslr mirrorless and it works beyond my expectations.

Rated 5 out of 5 by from I'm consistently amazed As I pass 5,000 shutter actuations on my a7r3 I'm consistently amazed by the camera. I'm a retired professional with over 50 years experience and I tell you that this camera makes up for my failing eyesight and occasional technical flubs. ISO is beyond anything we dreamed of and with the 24-105 zoom I've stopped carrying a bag. This features on this machine are way beyond my needs or skill set. Nice to have something to grow into.

Rated 5 out of 5 by from Amazing Camera! Bought this camera about a month ago and wow I love it nothing to complain, its perfect for what I do, I have owned a bunch of other cameras and decided to switch from fuji xt2, it was but it couldn't tether and didn't work with lightroom or capture one at the time. So now I own this amazing camera and never plan on using any other brand. Thanks Sony

Rated 5 out of 5 by from Digital equipment at its peak Simply amazing photographic results. Full frame 80+ m/b files with astounding color,clarity and sharpness. Been using the a7r markiii in aerial photography and really enjoy its size and overall quality. If you have large hands a battery grip will greatly help. For those seeking professional level pictures.

Rated 5 out of 5 by from A7R iii Just stunning! After shooting Canon DSLRs for over 15 years and investing a lot in Canon lenses, I decided to try the A7R iii after reading reviews that said it now had one of the best focus systems available and Sony was making very good lenses. I was hoping to get a smaller camera than my Canon and the Sony body is a little smaller than my 5d III Canon but some of the Sony zoom lenses are actually big .The combination of fast 10fps with a 42MP is jaw dropping.Eye AF is now on whole new level and not only with Sony lenses but with Canon lenses also. The battery is larger and has a much greater capacity, so much less risk of running out of juice while touring and taking lots of photos.Still a good idea to get a spare battery. Simply Best Camera Ive ever owned!
