The Sony a7R III uses the same sensor as the a7R II that came before it, but just about everything else has changed. The image processor and circuitry that drives it are new, which Sony says improves dynamic range. The processor also drives a new autofocus system, which allows the camera to track moving action at 10fps—at 42MP resolution. I’ve only had a few hours to shoot with the camera so far, but have some first impressions to share.
Sony A7r III
The star of the show is as with the previous A7R full-frame 42.4-megapixel EXMOR R sensor powered by a BIONZ processor.Its autofocus is up to twice as fast as the A7R II’s, and the new model is capable of fast AF/AE tracking for continuous shooting at up to 10fps, up from the 5fps you could squeeze out of the last A7R.
The sony a7R III looks and feels a lot like the a7R II—they use the same chassis. It measures 3.8 by 5.0 by 2.9 inches (HWD) and weighs 1.5 pounds. The body is protected against dust and splashes, as are all Sony FE lenses.There are a few physical changes, notably touch sensitivity on the LCD, a larger EVF, a dedicated focus selector, dual memory card slots, and a higher capacity battery.
The top plate houses, to the right of the hot shoe, a locking Mode dial, C1 and C2 buttons (both customizable), and a dedicated EV dial with third-stop adjustments from -3 to +3 EV. The power switch surrounds the shutter button and sits atop the handgrip, just ahead of C1 and C2. On the rear we see some control changes. The C3 button has moved to the far left top corner, with the Menu button in its familiar place to its right.
The sony a7R III finally has a dedicated control to adjust the autofocus area. This is a godsend if you prefer to use a flexible spot for focus. Below it you find the Fn button, a control dial with a center button and four directional presses; Display, Drive Mode/Self Timer, and ISO are marked on the body, but as with most of the buttons, they’re customizable. Finally you get Play and Delete/C4.The display itself is 3 inches in size and packs a 1,440k-dot resolution, a modest bump from the 1,228k screen used by the a7R II. The EVF is also upgraded, and it’s a more substantial jump. The new finder maintains the high 0.78x magnification, but is sharper at 3.6 million dots, up from 2.4 million.
Power and Connectivity
The sony a7R III discard the FW50 battery utilized by past models. It decides on the more up to date FZ100 battery presented in the a9. The bigger battery has more than twofold the limit. As indicated by CIPA standard testing the battery is useful for around 650 pictures utilizing the back LCD and 530 with the more eager for power EVF. I caught near 1,000 Raw+JPEG pictures alongside around 10 minutes of 4K video in a night of testing and just consumed through about portion of the battery. Those figures incorporate overwhelming utilization of the 10fps catch choices.
One is the long standard micro USB, the other is the more modern USB-C, with support for faster transfer speeds. The USB ports are also used for tethered shooting. Other ports include PC Sync for external flash, 3.5mm microphone and headphone, and micro HDMI. There are dual memory card slots, both with support for SD, SDHC, and SDXC media. You’ll need to use a U3 card to take full advantage of video features.
The sony a7R III highlights Sony’s most recent mixed drink of remote correspondence, which incorporates Bluetooth, NFC, and Wi-Fi. I had constrained time with the camera so I didn’t combine it with my telephone. Bluetooth is utilized to set the camera’s clock, keep an association with your telephone alive for faster blending, and add GPS information to pictures, in view of your telephone’s GPS. NFC will dispatch the Sony PlayMemories Mobile application on perfect gadgets, and Wi-Fi is utilized for picture exchange and remote control. PlayMemories Mobile is accessible for Android and iOS.
Performance and Auto focus
The sony a7R III has a pristine mechanical shade, intended to limit vibration, while in the meantime supporting 10fps catch with 1/250-second blaze adjust speed. With strobes that are fit for terminating that rapidly you’ll have the capacity to shoot quick moving activity in the studio.t’s ready to track subjects at such a high rate on account of its on-sensor self-adjust framework. A blend of 399 stage distinguish and 425 differentiation focuses cover around 68 percent of the sensor range, with the focal 47 percent secured by stage.
The sony a7R III has a brand new mechanical shutter, designed to minimize vibration, while at the same time supporting 10fps capture with 1/250-second flash sync speed.The images above, two sequential shots from a 10fps burst sequence, are an example of how you can use the a7R III to freeze motion and capture intense action in a studio situation.the a7R III has a fully electronic shutter option. It allows for silent shooting, which is a plus for covering weddings and events, as well as for wildlife photography.
The sony a7R III uses the same full-frame 42MP BSI CMOS sensor as its predecessor. Sony states that improved circuitry and image processing deliver improvements in image quality. The in-body image stabilization is also slightly improved. The 5-axis sensor-based stabilization system is now rated to compensate for 5.5 stops of shake, up from 5 stops. The added precision isn’t just used to ensure images are as sharp as possible, however. Sony is using it to implement its own high-resolution pixel shift capture system.
When using the mode, the sony a7R III captures four images in succession. You can set the interval between capture, with the shortest duration set at 0.5-second. These photos must be combined on a computer using Sony software; that’s in contrast to the Pentax K-1, which does it in-camera.Sony showed off some side-by-side examples in the form of glossy finish prints and I could see a bit more texture in images captured in this manner. This is similar to what I’ve seen when using Pixel Shift on the K-1 in the lab.
Sony showed off some side-by-side examples in the form of glossy finish prints and I could see a bit more texture in images captured in this manner. This is similar when using Pixel Shift on the K-1 in the lab.You get 4K footage with full frame width with no pixel binning. The a7R III can also shoot in Super 35 crop, about the same as an APS-C sensor area, with 5K oversampling for even better quality footage.the flat Slog 3 profile for the most versatility when trading footage—even the video delivers 14 stops of dynamic range.
Interior account is packed utilizing XAVC S at up to 100Mbps. On the off chance that you require greater quality, you can yield a clean 4:2:2 flag over HDMI to send to a field recorder. You can shoot 4K at 24, 25, or 30fps. In the event that you dial back determination to 1080p you’ll have the capacity to wrench the edges quicker—50, 60, 100, and 120 fps are additionally accessible.
The sony a7R III does some things that an SLR simply cannot. Sensor-based focus means you’ll never have to fine-tune a lens AF system, and portrait and event photographers will find the Eye OF capability invaluable. The area covered by the focus system is larger than you’ll get in a full-frame SLR, so you can better track moving action. Sony has been growing its FE lens line at a fairly staggering pace. It is launching a new FE 24-105mm F4 G OSS zoom along with the a7R III and promises to deliver a super telephoto 400mm F2.8 prime next summer. There are still some holes, and while you can cover those gaps with Canon-mount glass and an autofocus adapter like the Sigma MC-11, I’ve found that using an adapted lens doesn’t net the same consistently quick autofocus as you get with a native FE lens.
