What Are The Key Difference Between Sony a7c vs a7iii ?

As a beginner, it’s pretty confusing to determine which is better. Don’t worry, I’m here to help you. I’d make a list of features.

You’ll get all the possible differences based on the features. Thus, you can quickly figure out which camera is actually suitable for you.

Let’s have a look:

#01. Sensor Resolution

The first thing that every professional inspects is the sensor resolution. Actually, it is a traditional and common practice after the revolution of the Camera industry.

You’ll get advanced 24.2 MP resolution, which is an illuminated 35mm full-frame sensor in Sony alpha 7c. However, alpha 7 iii has a similar resolution.

In the case of photo clarity and aesthetics,  you can’t easily differentiate. Both will get 9 out of 10. Furthermore,  both have a similar ISO range, which is 50 to 204,800.

There is a slight difference in webcam resolution. You’ll get 25.3 MP resolution in alpha 7c and 24.2 in alpha 7 iii. If you’re a content creator, then you can consider this option.

#02. Image Quality

Previously, I’ve already clarified that you can’t see too much difference in photo quality. I’ve got nearly the same result in wildlife and street photography.

However,  I’ve got differences when capturing photos in low light conditions. Here,  Sony a7iii will win over the alpha a7c.

The low light iSO of a7iii is 3730, whereas a7c has 3407. It can be the reason to choose the Sony a7iii for night mode lovers or event photographers.

You’ll get a significant benefit from the viewfinder magnifications in Sony a7iii. It has up to 0.78x magnifications.

On the other hand,  alpha 7c has 0.59x. So,  you will enjoy capturing what is located in the distance.

#03. Video Quality

Now, let’s talk about the video quality. The overall video quality in Sony Alpha 7c and 7iii is nearly identical. You can record 4K ultra HD at 3840 x 2160 video resolution.

Moreover, you’ll get at least 120 fps video recording. So, what’s the difference?

There is a video recording limit in alpha 7iii, whereas a7c has unlimited video recording facilities.

If you have a big project or must complete more shooting in a single day, then it’s better to choose a7c over a7iii.

I’m sorry to tell you that the Sony Alpha A7c has no front dial system. This is generally used to moderate the shutter speed or aperture. On the other hand, you’ll get this facility in a7iii.

#04. Autofocus

Sony Alpha 7c and 7iii both have a powerful autofocus. Both have precise autofocus, which is useful for detecting the image faster than other similar-range cameras.

Both have better AF tracking, real-time face and contrast detection and, lastly, 693 focus points. So, what’s the core difference?

Sony Alpha 7c has better and updated AI-trained detection capabilities.

When you select the tracking mode in its AF area options, the camera adeptly maintains focus on the subject. Sounds cool, right?

On the other hand, the Sony Alpha 7iii has less smoothed Eye-AF and subject tracking than the a7C. In addition,  this model needs more accuracy.

In this way, it can manage to follow the entire subject rather than the specified part.

#05. Viewfinder and LCD

Sony Alpha 7c and 7iii both have an electronic viewfinder. The electronic viewfinder is quite familiar and more advanced than an optical viewfinder.

Generally, the chief function of the electronic viewfinder is to make the captured image apparently visible. Both have a similar dot point, which is approximately 2360k.

There is a little difference between them. You’ll get the minimum focus sensitivity is EV=-4 in Sony alpha 7c and -3 in a7iii. However, it would not find any major issues.

Lastly, with the help of this viewfinder, you’ll get 100% coverage. Thus, you can easily utilize the full resolution.

#06. Screen

The screen is another consideration that you should not neglect. In this mirrorless edge, who does not love a touchscreen?

The touchscreen provides more easy accessibility and flexibility when shooting.

You’ll be happy to know that both a7c and a7iii have touchscreen display. You don’t need to waste your time by clicking keys manually.

The Sony Alpha 7c has a Vari-angle 3-inch touchscreen. This type of screen is more flexible than a tilting display.

You can easily move the display based on your shooting type. So, you can capture selfies, wide-angle photos, and other angles photos without any hesitation.

On the other hand,  Sony Alpha 7iii has a tilting 3-inch touchscreen. The only problem is it can only move up and down.

But, the major positive side is it can be more durable than a vari-angle screen. Moreover, this type of display is lightweight.

#07. Shutter Life

Shutter life or shutter life span is another essential consideration. Actually, the core function is the duration of exposure.

It means it resolves how long the camera’s image detector is exposed to sunlight.

The minimum shutter speed in Sony a7c and a7iii is 1/8000 seconds. So, you can enjoy the same shutter speed.

This shutter speed takes a short exposure time. Thus, you can capture the subject very fast and accurately.

But, you should avoid capturing in the extreme or under conditions. It can be harmful to your camera and probably damage the mechanism.

So, it’s better to use an electronic shutter whenever possible.

#08. Lens Quality and compatibility

Sony A7c and Sony A7 III both have an optical zooming lens. You can use both auto and manual focus.

The Maximum Aperture in a7c is 5.6 f, whereas a7iii has 4 f. In this regard, you’ll get slight benefits in a7c.

Both have a similar autofocus point, which is approximately 693.

The Sony A7c and Sony A7 III are equipped with the Sony E lens mount. Additionally, you can use a Sony GM 35mm 1.8 lens as well in both of them.

Another recommended lens is the Zeiss FE 2 8/3.5 lens. Moreover, you can use 204 types of lenses, which explicitly cover the Full-frame sensor.

#09. Battery life

Battery life is another important aspect that you can’t avoid. Their battery duration is pretty good in the same price range. You’ll get approx 5 hours of battery backup.

So, how many pictures can you capture within this duration? You can capture at least 730+ photos with Sony Alpha 7c.

On the other hand, you can capture 600+ photos with Sony Alpha 7iii. In this regard, a7c has got more upvoted.

Generally, video recording takes more batteries. So, you can increase the amount of shots without recording any videos.

Overall, the exact amount depends on how many activities you’ve done.

#10. Brand Ecosystem

Mirrorless cameras are popular because of their use of a variety of lenses. Usually, DSLR has no such benefits. That’s why the popularity is decreasing day by day.

Sometimes, we want to use 3rd party lenses because of the low budget. So, is it safe to use? The answer is Yes. You can use several 3rd party lenses.

For example:

I recommend using Tamron 17-28mm f/2.8 Di III RXD as a 3rd party lens. If you cannot purchase any E-series lenses, then you can try this lens for better performance.

So, what about the Sony Alpha 7iii? Based on my experience, I got good results by using Viltrox 85mm f 1.8 lenses at my friend’s wedding. So, you can try this lens as an alternative to Sony E-mount lenses.


Is Sony A7III a professional camera?

The answer is “Yes”. From the studio owner to part-time photographer, they are still using a7iii for their professional job.

You will get a great experience with its 120 fps video recording.

Not only videography, but it’s also quite popular for snapping quality photos. So, indeed, it’s a great piece for professional work.

Does Sony A7C have image stabilization?

Obviously, Sony Alpha 7c has a full-body image stabilization. This is a 5-axis image stabilization.

That means it improves your photo from 5 sides like pitch, roll, yaw, X, and Y. This way, you’ll get a sharp image even in darker or low-light conditions.

The 5-axis IS is also effective in videography. With the help of this feature, you’ll get a smoother experience than others.

Is Sony A7 III good for beginners?

Yes. As a newbie, you can use both auto and manual focus. The dashboards are not complex.

You don’t need to spend extra any time to learn the entire configuration. Thus, you can capture photos like a PRO.

Moreover, this camera is supported by a wide range of 3rd party lenses. So, you can mount any supported lens at any time.

Is Sony A7C good for low light photography?

The Sony A7c has a high ISO setting, which allows it to capture photos in low-light conditions. Due to its full-frame sensor, it can produce high-quality images.

Its sensor can easily capture and detect the subject without any issues. So you won’t feel annoyed while shooting at night.

Can you use A7C in rain?

Yes and No, both. It can tolerate splash and a small quantity of rain. It’s highly advisable not to use it during heavy rainfall. It results drained the battery and lens.

This results in massive costs for repairing. If your camera is wet somehow, you should pay attention to this. Make sure the device is appropriately dried.
