Sony A7RM4A (stand-alone)

It was originally intended to buy the A7RM3A. The price difference between the A7RM4A and the A7RM4A is 4600 yuan, which is 2021.11.01. Because A7R2 was used before, it has a special preference for high pixels. So the new product, A7M4, passes directly. Although Sony released it at a very precise time, he also saw many videos and articles on the Internet evaluating A7M4. In general, this machine belongs to the video and photo repair type. I usually take photos, so it is more firm to choose between A7RM3A and A7RM4A. First, I bought an A7RM3A directly. JD bought it, but it hasn't been opened yet. I chatted with friends about buying this machine. A friend said that A7RM3A is an upgrade of A7R2, not an innovative product, but an old product launched in 2017. Both the sensor and button layout are better than A7RM4A. Although A7RM4A is an "old model" launched in 2019, it is the only one with more than 60 million pixels. I also explained why I bought the A7RM3A. One was the price and the other was the size of the RAW format file, because the evaluation said that the RAW format of the A7RM3A did not compress a file of 80MB, and the RAW format of the A7RM4A did not compress a file of 120MB, which somewhat deterred me. However, after the actual purchase, the RAW format of the compressed A7RM4A was chosen to be about 58MB. After all, family photography is still the main format, and occasional travel is the second. Even the JPG format of the A7RM4A is very good. Therefore, I think that if the economy allows, you would rather be ruthless. You will not regret entering an A7RM4A when you buy a new one rather than an old one.

The r2, which has been used for several years, can't stand the temptation of high pixels and the seduction of sony, so I bought the R4 at once. I know that this guy's ability to control 60 million pixels is still a bit limited. It's not much better than r2. The workmanship is average. It's not art, but it gives people the feeling of ordinary industrial products. However, there is still obvious progress. The focusing speed is much faster, at least it can match my big eyes. The old cn family always thought that the camera kept its value. Sony completely subverted the market, and the cameras were more powerful than each other. That's what electronic products should be like! And forced you to change the fuselage

Although not the latest, the budget is here. Dissatisfied with the old menu interface and useless touch screen. But the overall hand feel and use experience are good. It is recommended to buy 7CR or new generation.
