Sony A7 IV Versus the A7 III: Comparison

The Sony A7 range has long been a series of well-known cameras, reaching a fantastic space between speculation and price, and on October 21 at 3pm GMT / 10am EDT the new Sony Alpha A7 IV was unveiled.

The previous Alpha A7 III is one of the best-selling non-reflective cameras with a full frame, but about 4 years after its first launch, it is probably a little longer for birds.

Since the 47-year-old A7 III road price is much lower than the Sony A7 IV when it was launched, why not buy a new baby on the block? We bring you this in-depth comparison of Sony A7 IV vs A7 III to help you choose between the two.

Sensor

Sony A7 III has a 24.2 MP BackSide Illuminated (BSI) Exmor R that delivers still image quality and 4K video.
The 24-megapixel has become the epitome of the latest cameraless and mid-range cameras, with the highest megapixel counts set for premium flagship models.

The A7 IV enhances the ante using the newly built 33 megapixel Exmor R BSI CMOS sensor, which is likely to be the sensor of choice for all Sony full-featured cameras as well as the front-end.

Processor

Sony A7 IV uses the latest BIONZ XR processor, as it was previously acquired on the Sony A7S III camera, which offers 15+ flexible range stops.

ISO speed

There is almost no choice between the two models here, both A7 III and A7 IV which offer the ISO range all the way up to ISO 204,800.

Video

A7IV provides 4K UHD video recording in XAVC SI format, up to 60fps at 4: 2: 2 color depth of 10-bit memory card inserted or over HDMI to external compatible third party records with long wavelength. GOP or All-Intra. coding.

4K / 30p video has been moderately extruded from 7K in full frame, but unfortunately 4K / 60p is taken in 4.8K in APS-C Super 35 mode.
So when it captures 4K at 30p, the camera uses full image sensor to capture over 7K value data, but at 60p, 1.5x throughput.
Supports S-Cinetone, HLG, S-Log3 and S-Log2 profiles. 4K / 60p recording or 10-bit recording is not available in the older A7 III and it uses 1.2x output on 4K / 30p video, and though the Super 35mm 4K / 60p on A7IV is disappointing, it is still a step great. forward from the Mark III camera.

Both can record Full 1080 HD up to 120fps, with dedicated slow and fast mode offering independent rates from 1fps to 120fps.
The A7 IV also has a few inherited features in the A7S III which set it apart from the A7 III. These include AF Speed ​​A7S III settings, no recording time at all, bright blue color, ability to shoot live videos, live streaming support, and dual recording of NTSC and PAL on a memory card without re-formatting it.

In addition, the one-touch movie button has been removed from its unfavorable location from the back of the A7 III to the top panel of the A7 IV.

Sony A7 IV supports Digital Audio Interface to allow the use of the ECM-B1M digital gun microphone. It also has a list of new video settings that you won’t find in A7III, which includes Breathing Compensation to help reduce breath-taking with some Sony lenses, Shockless White Balance to make manual adjustments to smooth white balance, Flexible Exposure Mode. switching between automatic and human exposure settings separately at the opening and shutter speed, as well as two types of Shot Marks to mark your favorite capture or scenes.

Look

A7IV inherits Creative Look pre-set images from JPEG images from A7S III and A1 models, and six additional ‘traditional’ key can be stored manually for quick access.

Automatic focus

The A7 IV auto focus system supports Real-time Tracking AF and human AF, animal and bird Eye, both vertical and animated, making it Sony’s first camera to provide full AF support for both shooting modes.

Price

One of the more controversial aspects of the new camera is the launch price of Sony A7 IV in Pakistan. Whilst the Sony A7 III price in Pakistan has been on the market for a few years now and has naturally declined in price, we still think that Sony is being somewhat over-ambitious with the A7 IV.

It’s no longer the “entry-level” model that it’s predecessor clearly was – instead the A7 III will continue in that role (Sony always carry on selling previous models), along with the more compact Alpha A7C.

Conclusion

Creating the successor to one of the most popular full-frame cameras of recent years was always going to be a difficult task, especially at a time of rising prices and component shortages.

A lot has changed in the four years since the A7 III was released, and it’s clear that the new Mark IV is a much more capable hybrid camera than its predecessor, on paper at least.
