Is Sony a7C good for Astrophotography?

Sony has been widely regarded as the preeminent brand in the field of astrophotography photography for many years. After having experience with the A7rii, A7riii, and A7iii, I decided to switch to the Sony A7c, which I believe to be one of the best cameras in Sony’s current portfolio. I’ve used it for travel, weddings, YouTube videos, and landscape photography, among other things.

But is it any good for astrophotography? Yes!

The A7c is one of the best cameras for astrophotography because of its settings, sensors, and lens selection. Additionally, its form factor is ideal for star tracking, making it one of the best cameras for astrophotography.

Bright Monitor Mode

The bright monitor mode that Sony offers is a game-changer. Because of this, I solely use Sony cameras for my astrophotography.

Bright monitor mode allows you to enhance the amount of light that enters your sensor, allowing you to see in low-light situations. In the event that I am unable to see a composition during the night, I switch to the bright monitor mode. If I am having trouble seeing where I am going, I switch to the bright monitor mode.

I use it as a custom button on my center button, and if I didn’t have it, I’d be completely confused.

Although the electronic viewfinder (EVF) on the Sony A7c isn’t very good, some people don’t like the camera because of this, but it’s not really necessary for astrophotography. When I was shooting with the A7riii, which has a sensor with a better resolution than previous models, I didn’t notice much of a difference.

The Best Camera Sensor for Astrophotography

Both the A7C and the A7iii use the same sensor, which is one of the best sensors for astrophotography due to its excellent pixel pitch and its ability to function well in low light conditions.

For astrophotography, you could be enticed to purchase a sensor with a high megapixel count, but in my opinion, 24 megapixels is the optimal resolution. If you choose the A7iv or A7Riv, you will receive a greater number of megapixels; however, larger sensors are more sensitive to movement in the night sky, so you will need higher shutter speeds.

When photographing stars with a quicker shutter speed, you will get crisper stars, but the amount of light that will reach your sensor will be reduced. The sensor found on the A7c is identical to the one found on the A7iii. It performs exceptionally well in low light and enables you to lower your shutter speed while maintaining the ability to capture sharp stars.

Additionally, the A7C is one of the best cameras available for shooting in low light. You will observe a greater amount of noise with practically any other camera (A7riii, A7riv, Canon RP). The A7siii is the only full-frame camera that has a superior sensor, but it only has 12 megapixels of resolution.

In 2005, professional photographers were using cameras with a resolution of 6 megapixels to capture magazine covers. It’s not that I have anything against 12 megapixels; it’s just that I’ve spent too much time with cameras that have larger megapixel counts.

Sony A7c lenses for astrophotography 

The Sony 20mm 1.8 is my go-to lens for night sky photography, but I really adore the 24mm 1.4 GM that came with my camera. I believe the coma performance is slightly improved with the 20mm 1.8, and it is the ideal focal length for photographing the milky way.

These are the additional lenses that I use for astrophotography at the moment.

Sony a7C is the best camera for star tracking

Because of its diminutive size and weight, the Sony A7c is an excellent camera for star tracking. The vast majority of star trackers have weight limits, however, the A7c’s form factor ensures that this will not be an issue.

I pair the A7c with the Tamron 17-35 2.8-4 and an MC-11 adapter so that it may be used for star tracking. It appears that Tamron has ceased production of this lens, but I still consider it to be the best option for tracking because of how well it handles coma.

SOny a7C is the most affordable Camera for Astrophotography

The Sony A7c is an excellent full-frame camera that also comes at a reasonable price. It comes in at roughly the same price as the A7iii, which is $1800. I prefer it better since the focusing is quicker, it can autofocus during video, and it has a smaller form factor.

Consider the Nikon Z5 as an additional option if you are constrained financially. The low light sensor and excellent ergonomics are included, however, there is no bright monitor option available on this model.


The Sony A7c delivers excellent results when used for star photography. It has the performance level of a professional camera, a brilliant monitor mode, an outstanding sensor, terrific lens selections, and it’s not too expensive. It functions well as a star chart, and its compact size makes it an ideal travel companion for use during the evening hours.
