Recently, a friend asked me such a question, which I think is more interesting.
This question is: the main video, 4k120 is not just needed, how to choose between the new Fx30 and the second-hand A7s3?
In terms of price, the price of the brand-new Fx30 is around 12,000 yuan, while the price of the second-hand A7s3 is around 1.5-16,000 yuan.
For this question, most people's opinion is: does this still need to be considered, of course, it is A7s3.
But I have a different view on this.
If it's just about performance,It's definitely SonyA7S3It's more suitable,After all, this is a full-frame mirrorless,And it's only 12.1 million pixels,It can be said that the high sense is invincible,Even if the ISO soars to12800,The picture quality is still very pure。
However, if you consider it from the perspective of practical use, as a veteran driver with more than ten years of shooting experience, I don't recommend buying a second-hand Sony A7S3.
Why? Because if you think about it, who is the person who buys and uses the Sony A7S3? Ordinary users will not buy this kind of machine,Most of the people who use Sony A7S3 are some professional video creators and video studios,And as far as I know,At present, some Internet celebrities live broadcast,Sony A7S3 is also one of the most used models。
To put it bluntly, Sony a7s3 has always been a model that has been used as a productivity tool with a high frequency, and this product was launched in July 2020, 4 years ago, as long as it is sold now, basically CMOS image sensors have been worn out.
So if you have to choose between the two, you should consider the Sony FX30. Although this product is half frame,But there is also a built-in cooling fan,The image quality is also enough,And because the pixel is higher,Sony fx30Shooting4K is super quality,In fact, the picture quality is not worse than Sony a7s3,And if you take pictures,Sony fx30Take pictures with a higher resolution。
In addition, if it is a professional shooting, the role of lighting is more important than the shooting equipment, so you should focus on the lighting factor, you look at some professional movie cameras, the sensor is only half frame size, so for video shooting, it is not that the larger the sensor, the better.
Of course, if you have to shoot with a full-frame mirrorless shot, and you want to have a better high-sensitivity performance, you can take a look at the Sony ZV-E1, which uses the same sensor as the A7S3, and the high-sensitivity aspect is also invincible.
And in terms of focusing performance, Sony ZV-E1 uses Sony's latest AI intelligent focusing chip, which has faster and more accurate focusing and video focusing performance.
Of course, Sony ZV-E1 shoots high-bitrate video continuously for a long time, there will be overheating problems, mainly because this product does not have a built-in cooling fan, which is also easy to do, you can paste a heat dissipation sticker similar to an SSD on the back of the machine, which can effectively solve the problem of overheating for long-term shooting on the fuselage.
In addition, if the 4k120 is not too rigid, you can also consider Panasonic S5 second generation and S52X models.
Panasonic S5 2nd generation and S52X have better body image stabilization performance, and both have built-in heat dissipation devices, but also have 6K video shooting specifications, in addition, S52X has a direct recording function through USB connection SSD, in addition, Panasonic S5 second generation and S52X are more cost-effective.
