The Sony Alpha A7R IV proves that Sony is still very much on a roll with its Alpha line. While a handful of niggles from previous models remain, the class-leading pixel count, revamped Pixel Shift Multi Shooting mode and autofocusing improvements in particular show the company continuing to innovate, and push further in all the right directions. And, while it’s not cheap, it commands less of a premium than previous Alpha models when you consider just what you’re getting here.
- Great handling with improved ergonomics
- Very fast and intelligent AF system
- Bright, sharp and high-contrast viewfinder
- Excellent 4K video quality
- Pixel Shift Multi Shot capable of superb detail
- Well-behaved metering system
- Some AWB and focus issues
- Rolling shutter noticeable in videos
- Mode dial more awkward to access than before
- Touchscreen could be better
- No in-camera raw processing
- No motion correction in Pixel Shift mode
Sony has spent much of the past year proving just how seriously it’s taking the needs and demands of enthusiast and pro photographers.
It updated its flagship compact proposition with the RX100 VII, while the Alpha A6400, Alpha A6100, and Alpha 6600 gave enthusiasts looking for a mirrorless camera many places to turn for their next models.
Lens releases have ranged from the teeny FE 35mm f/1.8 through to the Sony FE 600mm F4 GM OSS behemoth, with many in between, while new firmware updates have improved autofocus performance across its most popular cameras, such as the A9 and Alpha A7R III.
And now Sony has launched the A7R IV, a 61MP full-frame addition to its Alpha portfolio, and a follow-up to the 42MP Alpha A7R III. It’s rare to see such a jump in pixel count between two generations of models, but then Sony isn’t a company that tends to do things by halves when it comes to camera releases.
Furthermore, the move is perfectly in line with the company’s ambition to grab the number one spot for full-frame interchangeable-lens cameras worldwide – something it already claims to have achieved in the US.
- 61MP back-illuminated full-frame sensor
- 4K video recording to 24 and 30p
- 5-axis sensor-based stabilization (5.5EV stops maximum)
Sensor resolution may have taken something of a back seat to improvements to performance in other areas in recent years, but the ‘R’ line has always been about resolution, and it’s unquestionably the main pull of this new model.
The 63MP sensor yields 61MP pictures as standard and, likewise with the sensor inside the past A7R III, flaunts a back-lit up plan for better light-social event control. Sony guarantees up to 15EV prevents of dynamic range from the sensor, which is additionally what it guaranteed for the A7R III.
As is currently standard on Sony models of this bore, SteadyShot Inside picture adjustment has additionally been consolidated into the body. This guarantees a most extreme 5.5EV-stop compensatory impact, and is glad warrior on whether you’re shooting stills or catching recordings.
This framework is additionally behind the Pixel Shift Multi Shift giving mode, an element we saw already yet one that has been given a noteworthy lift here. This catches a progression of pictures that can be along these lines converged to make a solitary, super-high-goals document.
So what’s extraordinary? Though the A7R III had the option to catch pictures bound for 169.6MP composites, with its higher-goals sensor the A7R IV vows to convey records at an amazing 240MP. The catch is this isn’t possible in-camera; you have to utilize the Imaging Edge programming suite that is packaged with the camera.
Sony has outfitted the model with the most recent cycle of its BIONZ X Processing motor, and expresses that Advanced Detail Reproduction Technology and Area-explicit Noise Reduction have been changed to consider the sensor’s high goals.
The processor additionally enables the camera to catch pictures at a pace of 10fps with self-adjust and auto-presentation empowered; while not exactly class-driving, that is still noteworthy when you consider the higher sensor goals here.
Some of the time you’ll require 61MP pictures less that you will additional scope from your focal points, and fortunately the Sony A7R IV will give you a chance to shoot in an APS-C crop mode (1.5x yield factor), with coming about pictures yield at 26.2MP. This is another component that has existed previously, yet it’s been redesigned here with expanded yield goals. APS-C focal points can likewise be utilized on the body on the off chance that you have any of these, with pictures again yield at this goals.
SONY ALPHA A7 III SPECS
Sensor: 61MP full-frame, back-illuminated Exmor CMOS sensor (62.5MP total)
Lens mount: Sony FE
Screen: 3-inch tilting touchscreen, 1,440,000 dots
Burst shooting: 10fps (with AF and AE)
Autofocus: Fast Hybrid AF system with 567 phase-detect and 425 contrast-detect AF points
Video: 4K to 30p
Connectivity: Wi-Fi, Bluetooth, NFC, USB 3.2 (Type C), Micro USB, HDMI Micro (Type D)
Battery life: 530 / 670 shots (Viewfinder and LCD)
Dimensions: 128.9 x 96.4 x 77.5mm
Weight: Approx. 578g (with battery and card)
The sensor and processor likewise cooperate to catch 4K recordings to a most extreme 30p, which can be caught in both full-edge and Super 35mm arrangements. When utilizing the last mentioned, the camera records 6K film with full pixel readout and no pixel binning to help improve the nature of film, before downscaling this to 4K.
Video recording is bolstered by a heap of further highlights, from a HLG (Hybrid Log Gamma) picture profile and both S-Log2 and S-Log3 gamma bends through to the recently observed Gamma Display Assist work, support for Time Code IN/OUT, zebra and clean HDMI yield.
With video, maybe the greatest change from before is the selection of another Multi Interface Shoe on the top plate, which takes into account sound to be recorded carefully. You can do this with the ECM-B1M shotgun receiver that was reported close by the A7R IV, in spite of the fact that you can in any case record sound through a 3.5mm port on the camera’s side on the off chance that you as of now have a mic with this association; a 3.5mm earphone port enables you to screen sound as it’s being recorded.
Another key change from the A7R III concerns the viewfinder. It’s as yet a 0.5-inch electronic viewfinder with an OLED board that invigorates at up to 120fps (or 100fps in PAL districts), and has an amplification of 0.78x in 35mm terms, yet the goals has jumped from 3.69 million specks to 5.76 million dabs.
The back showcase underneath it, be that as it may, has remained the equivalent, estimating three crawls in size and with a goals of 1.44 million spots. Indeed this can be tilted here and there for shooting from unbalanced edges and can be constrained by contact, in spite of the fact that touchscreen activity is somewhat more restricted here than it is on some adversary cameras.
Like the A7R III, the A7R IV has a couple of SDHC/SDXC card spaces around its side, and Sony has guaranteed that the two openings support UHS-II cards (the A7R III just had both UHS-I and UHS-II support in one opening, and just UHS-I support in the other).
Battery life has likewise been improved, with around 530 shots ready to be caught when utilizing the viewfinder, and around 670 when utilizing the LCD screen – as usual, these are CIPA assumes that are genuinely moderate contrasted with what will really be feasible by the normal picture taker.
