Perhaps the best crop camera from Sony. Ergonomically, it has the best grip in the hand out of all the cameras I've had.

Positives: Very good stabilization, similar to the GH5 but with specific Sony lenses. Build quality, screen.

(If you are ONLY a videographer, it is the ideal camera. There is no reason to go for the A74)

The negative is the multi-selector button. They have placed it in a position that I wonder how they thought of it. It is not convenient at all.

(ISO 6400 is very clean)

Update: After 20 or more mysterious weddings, I can say with certainty. It went from being my second camera to my first. The A7iv is very good but it became second now.
The FX30 has better autofocus than the A7iv, better dynamic range, better stabilization, it is 100% reliable at 40 degrees Celsius (I worked with it in 40-degree 4K outside in the sun and it didn't overheat at all), it has a better grip, and Sony Hellas offers a 5-year warranty

I bought it from Cyprus. It is a masterpiece for those who want to get into filmmaking and do not have a big budget. Although it is an APS-C camera, I prefer using it with FE lenses, even though I have minimal chromatic aberrations.

It has a dual ISO base, which means you can increase the ISO without much grain in the footage, and it is a very reliable tool for low-light conditions, even though it is a crop sensor.

It takes two cards simultaneously for backup, and I would recommend using UHS-II cards with a minimum speed of 300mb for optimal results.

With the battery, you can record almost two hours in 4K at room temperature.

It has the S-Cinetone profile, which is excellent for accurate color grading in human skin tones.

It is the ultimate entry-level tool for a relatively experienced videographer, not a beginner as Sony presented it.
