Relax and enjoy ecological photography. Sony Black Card RX 10M4 evaluation.

IT 168 evaluation unconsciously, Sony's RX 10 series has been upgraded to the fourth generation. Compared with previous generations of RX 10, the lens optical structure is continuously optimized and the video specification is improved. This RX 10M4 focuses on improving the focusing performance of the camera, and also expands the use scene of this camera from tourism photography to ecological photography. What are the professional market-oriented designs of RX 10M4? Can the image quality meet the professional needs? Can concentration be a big responsibility? This is the question that needs to be answered in this evaluation.

Advantages:

1, the lens resolution performance is first-class, and the 600mm full aperture image quality is available;

2, excellent focusing performance, and the use experience is close to its flagship A9;

3, support macro shooting, eco-photography is really a mirror of the world.

Regret:

1, the performance of high-quality image quality is average;

2. Focus tracking sensitivity adjustment is not supported.

Evaluation summary:

Looking back at the previous generations of RX 10, everyone is still saying that this machine is "good or not, but it is a bit cumbersome". But in the generation of RX 10M4, it seems that everyone is saying that this machine is "really good, small and good". What is the reason that leads to the opposite direction of comments when the fuselage changes little?

The reason is that the reference for evaluating this product has changed.

In the past, when we evaluated the RX 10 series cameras, we always compared the RX 10 series with the RX 100 series of the same door intentionally or unintentionally, and the result was naturally that the RX 10 series was a little too big.

In the generation of RX 10M4, the 600mm telephoto and A9-like powerful focusing system, coupled with excellent image quality, have actually exceeded our expectations for this volume camera. So our contrast object naturally changed from RX 100 series black card to A9+ telephoto gun. So we naturally come to the conclusion that RX 10M4 is "really good, but little good".

Sony RX 10M4 appearance comments, adding a focus restriction mechanism.

As the fourth generation product of Sony RX 10 series, the body of Sony RX 10M4 seems to have little change from previous generations. However, in some small details, we can still see some careful thoughts of Sony. What are the exquisite designs and workmanship? Let's have a look.

The design of RX 10M4 continues the tradition of Sony Black Card series, and the metal body is full of cold feeling.

The lens is equivalent to 24-600mm, which can be attacked (600mm super telephoto) and retreated (24mm super wide angle).

The main operation buttons of the fuselage are mostly concentrated in the right hand area of the back.

In addition to the regular buttons at the top, there is also a small shoulder screen design.

Look carefully, there is also a click on/off switch at the bottom of the lens, and you can choose whether the lens aperture can be adjusted indefinitely. At this time, when shooting video, you can get a smooth transition effect from shallow to deep by adjusting the infinite aperture.

There is also an exposure compensation dial on the right shoulder of the fuselage, which is very convenient to view and adjust the exposure compensation.

Mode dial on the left shoulder. Although there is no locking mechanism on the turntable, it feels tight and should not be easily misoperated.

I won't read the viewfinder parameters for you. The intuitive feeling is wide and bright, and the refresh speed is very fast. In short, the experience is very good.

The SD card slot on the right side of the fuselage, alas, I wish I could give you a dual card slot.

There are various interfaces on the left side of the fuselage, including audio input, fuselage echo, Micro USB data (supporting charging) interface and Mini HDMI video output interface.

It is worth mentioning that the lens of RX 10M4 supports focus limitation. These two gears are full range gear and 3m- infinity gear. This helps to avoid focusing interference and get faster focusing speed.

The aperture of RX 10M4 is adjusted on the lens, and the design is very retro.

The bent state of the hood.

Hood combat (positive mouth) state. The coating of the previous group of Zeiss is green.

The back screen supports flipping &; Touch control, high and low angle framing freely.

The design of flip screen is very useful for both still photos and dynamic videos.

The batteries of RX 10M4 are FW-50, just like the A7 series of Sony's previous two generations.

The battery capacity is not large, but it should be no problem to shoot on this machine for one day.

Generally speaking, the fuselage of this generation of RX 10M4 has not changed much compared with the previous generation of RX 10M3. However, the addition of the focus restriction mechanism is indeed a key step for this camera to enter the professional photography market.

The O 1600 can be tested with Sony RX 10M4 high sensitivity.

The high sensitivity of the camera is directly related to the night scene and motion shooting ability of the camera. The better the high sensitivity of the camera, the higher the image quality in dark light, and the stronger the ability to capture moments.

Sony RX 10M4 is equipped with 1 inch CMOS sensor with 2065438+ megapixels. It stands to reason that the image quality at high sensitivity should be better than that of ordinary card cameras. Let's take a look at the actual performance of RX 10M4.

Put the camera on a tripod, turn off all internal noise reduction optimization and output JPEG files directly. Take a 100% enlarged screenshot of the position shown in the red box below each ISO file.

It can be seen that the picture quality of Sony RX 10M4 is the best in ISO 100. ISO200 decreased slightly, but there was little change. The details of the O400 continue to be lost, and the straight lines in the picture begin to become uneven, but the noise is well controlled; Speaking of ISO800, it seems that it has reached a watershed, and the noise suddenly appears. However, the loss of details is acceptable, and this performance has continued until ISO1600; At ISO3200, the details and noise of the picture suddenly became uncontrollable, and the picture entered a range that was not recommended.

So we suggest that when using RX 10M4, if you are very concerned about the performance of image quality, then use ISO 100 practically. If your requirements for image quality are not so harsh, we think that ISO 1600 should be the acceptable limit of the image quality of RX 10M4 when you turn on the in-machine noise reduction or do it yourself later.

600mm full open can be analyzed and tested by Sony RX 10M4.

For RX 10M4, the performance of telephoto end is undoubtedly more important than that of wide-angle end. After all, people who buy this machine are all for this 600mm super telephoto.

However, in view of the poor high sensitivity performance of RX 104, RX 104 urgently needs to open the aperture. Therefore, the performance of this camera under the maximum aperture of 600mm telephoto end has become the key to determine the usability of this camera.

Let's still look at the proofs, F4 aperture ISO 100, shutter11000 seconds, and take a 100% enlarged screenshot of the area shown in the red box.

From the real shot, details such as antlers and even eyelashes on deer eyes are presented. This kind of analytical performance can be said to be faultless.

Lexiang Eco-photography RX 10M4 Focus Macro Anti-shake Review

In the previous chapter, we analyzed the design changes and image quality performance of RX 104. Let's answer the last two questions about RX 104.

What is the focusing performance of 1.RX 10M4?

The focus limit switch is added to the lens of RX 10M4, which can reduce the focus stroke and improve the focus speed. On the other hand, the addition of this mechanism can effectively avoid the influence of obstructions on the focusing system (such as the glass and fence in front of the photographer). One more thing.

The screen supports touching and dragging to select the focus, and supports eye control AF, which will undoubtedly improve the efficiency of our focusing operation. One more thing.

However, there is one thing to mention. Although Sony RX 10M4 is very similar to its own micro-single flagship Sony A9, both in focus speed and focus range. One thing that RX 104 hasn't learned is that RX 104 doesn't have the focus tracking sensitivity adjustment option provided on A9.

This has no effect on shooting a single moving object, such as ecological photography. However, if it is used in sports photography, when obstacles frequently appear in front of the focus target, the lack of this option is likely to affect shooting.

This is also my only regret for the RX 10M4 focusing system. In view of the high overall usability, there is a little fly in the ointment.

Second, the macro performance of RX 10M4 &; Anti-shake performance of RX 10M4

The nearest focusing distance of RX 10M4 is about 72 cm, and the maximum magnification is 0.5 times. From the specification point of view, RX 10M4 has strong macro capability.

From the actual experience, due to the addition of anti-shake function, the handheld macro function of RX 104 becomes highly available. The above picture is a macro sample taken by the author with RX 104. It can be seen that even if the depth of field is very shallow, the hand-held RX 10M4 can still firmly lock the focus and take very clear photos.

Finally, as usual, the sampling time was in Nanhaizi Park in the southern suburbs of Beijing. I recommend it as a good place to walk children.
