In the early days of the Sony Alpha A7-series there was the A7, the A7R and the A7S. Things were quite simple. The A7S was the one for video, the A7R was the high-resolution model and the A7 was the more affordable option. It was fairly easy to choose the right camera.

The situation has got a bit more complicated since then. We’ve had the introduction of the Mark II versions of each camera, the Mark III version of the A7 and the Mark III and Mark IV versions of the A7R. Sony hasn’t officially discontinued any of the A7-series and they are all still available to buy new.

So how do you know which Sony A7 camera to choose? Well, in some ways the original distinguishing features still help:

Which Sony A7 Camera: Sony A7R III

Sony A7R series = High Resolution

With 61 million effective pixels on its full-frame sensor, the Sony A7R IV is the highest resolution model in the A7 range. It enables the camera to capture a huge amount of detail and, thanks to Sony’s fantastic sensor-building knowhow and the BSI design, noise is controlled extremely well. That said, we’d recommend making ISO 12,800 the top value you use if possible.

Meanwhile, its predecessor, the 42.4Mp A7R III has the same same sensor as the A7R II. Both of them resolve more detail than the original A7R which has a 36.4Mp sensor, but they can’t match the A7R IV.

Where the A7R III scores over the A7R II for image quality is with the improved dynamic range at the lower sensitivity settings. However, we’re only talking about around 0.5EV. And while that could be significant for landscape photography, if you use ND grads or composite images, then it’s not THAT big a deal.

The A7R III also feels more rounded than the models that go before it. Its autofocusing system is impressive so it’s even suitable for shooting sport.
Sony has improved the handling of each successive model. Consequently, the A7R IV’s handling is significantly better than the A7R’s and a little better than the A7R III’s. Like the A7R III, most recent camera features a touch-screen, but Sony hasn’t gone overboard with it. Sadly, it’s only really useful for zooming in and out of images or setting the AF point.

There’s also a joystick that simplifies setting the AF point on the A7R III and A7R IV, (and the A7 III). Of course if you shoot still life, macro or landscape photography that may not be a major issue for you. This is a bit fatter and easier to find on the A7R IV than the Mark III camera.

Conclusion

If you find the Sony A7R available at a bargain price, it’s worth considering. But it wouldn’t be our first choice of the A7R-series cameras. Its AF system isn’t a patch on the latest version and the handling can get annoying. The Eye AF (human and animal) that’s available with the A7R III and A7R IV, is superb, but if you want it to work for humans in video you’ll have to opt for the very latest model.
If you don’t need quick AF point selection and the fastest focusing, nor the improved dynamic range, then the A7R II looks like a good solid proposition. It also makes a significant saving on the A7R III.
However, if you can afford it, the A7R III makes a solid upgrade. The A7R IV, however is one of the best cameras available at the moment.

Which Sony A7 Camera: Sony A7SII

Sony A7S series = Video

While the A7S and A7S II are intended as the video cameras, Sony hasn’t stinted on the video features of the A7R II, A7R III. A7R IV and A7 III. However, where the A7S models win is with their low-light capability. They have a native sensitivity that tops out at ISO 102, 400.

Their low (12.2Mp) pixel counts mean that they handle noise extremely well.

What they don’t do well in low light, however, is focus. That’s not an issue for many videographers who routine focus manually, but it’s worth mentioning.

Conclusion

The big issue when thinking about buying a Sony A7 camera for video right now is that there’s supposed to be an A7S III coming in the not too distant future. Normally, that would mean it would make sense to wait and see what comes along, but it seems like we’ve been waiting for ever. Sony has confirmed that there’s an A7 III in the pipeline but it’s still to see the light of day.

Which Sony Alpha A7 Camera?

Sony A7 series = The Affordable Option

While the A7 II was pretty decent, the A7 III is much better. What’s more, at launch Sony priced it quite aggressively for a full-frame camera at £2000/$1,998 (body only) or £2,500/$2,198 with the 28-70mm lens.

That’s not a figure to be sniffed at, but that money brings you a very capable AF system, that’s streets ahead of the A7’s and A7 II’s. It also brings improved handling with the mini-joystick control, a touch-screen and twin card ports.

The A7 III’s full-frame sensor also has a pixel count of 24.2 million, which as well as being a popular figure, allows a good balance between detail resolution, file size and noise control. Add in 4K (3840 x 2160) video recording with S-Log plus a battery that has a much longer life than the A7 II’s and the Mark III looks like an easy decision.

Conclusion

In the UK the Sony A7 II can be bought for around £899 body only. That’s temptingly below the current £1,700 asking price of the A7 III. But the new camera gives you so much more, we’d be sorely tempted to save a little longer.

It’s a similar story in the US. The A7 III retails for around $2,000 and the Mark II is around $898.

Which Sony A7 camera should you choose?

If you’re still not sure at this stage then plump for the A7 III. It’s a great all-rounder that designed with enthusiast photographers in mind. Don’t be fooled by Sony calling it a ‘basic full-frame camera’. It’s far from basic. Sony wants to redefine the genre.

With the A7 III, you’ll be able to shoot a wide range of subjects including fast-moving sport and action. Noise is also controlled well and the level of detail in images won’t disappoint.

If you’re keen to get more resolution then the A7R IV is the best choice and its AF system is incredible.
