The exchange of my prophecies of the year did indeed appear!
A7M4 mocker R6 heat dissipation does not work lens group pit, R6 mock A7M4 is a half-frame camera. This is the classic Japanese enterprise dislocation competition ah friends, the year D700 VS 5D2 is so, 5D2 users mock D700 video garbage pixel low, D700 users mock 5D2 focus is sparse, more than ten years have passed or so.

Video
The advantages of the A7M4 in video are very obvious, but there is a fatal drawback, which is often ridiculed by R6 users.
The A7M4 provides three kinds of video encodings: within H.264 frames, between H.265 frames, and H.265, which can shoot 422 10bit. The R6 has only 422 10bit H.265. If your computer configuration is a little worse, cutting H.265 pieces will be very stuck, and the proxy file is an additional time long cost and storage cost. The A7M4 has H.265 with a high compression ratio and H.264, which does not require a high computer configuration, giving users a variety of choices, which is one of the biggest advantages of the A7M4.
The lens group of the A7M4 is far richer than that of the R6, although the R6 can also transfer EF lenses to shoot videos, but at least in the native mount lens, this piece is far inferior to the A7M4, both in quantity and price is not as good as the A7M4 lens group.
The biggest problem with R6 in video is heat dissipation, which is basically recognized, shooting 4K60P in a 25-degree environment to about 27 minutes of overheating off. However, the heat dissipation of A7M4 is not much better, if it is set to a standard of ten minutes, it may overheat, if it is set to "high", generally speaking, it will not overheat for more than 30 minutes (in an environment of more than 20 degrees), but it is also easy to overheat in an environment of more than 30 degrees.
The biggest problem with A7M4 is 4K60P cutting, which is also the most intolerable place for everyone, including many A7M4 users are scolding while using. The A7M4 was 1.5X cut when shooting 4K60P, that is, APS-C format (S35 format), so that it was ridiculed to take pictures of full frame, shooting video half-frame, although the A7M4 shot 4K30P is uncut, and it is 7K super-harvested to 4K. What are the consequences of this? I used 24-105F4G to shoot video, when shooting 4K30P is 24mm, shooting 4K60P is 36mm and even wide angle is gone, who can bear this? R6 beat 4K60P only a little cut, about 1.08X to 1.1X, that is, 24mm to 26mm, the impact is not large.
I used to joke that the A7M4 was paired with a Mating Horse 18-50 or a Tenglong 17-70 (both of which are APS-C frame lenses) very well, although this is a joke that the A7M4 is like a half-frame micro-single, but these two lenses to the A7M4 to shoot 4K60P is really no problem, a good choice.
Straight out the color
Sony's past micro-single straight out color is not good, but the new micro-single straight out is great, many friends around me have used Sony's new creative appearance presets are full of praise, I also feel very good after using it myself.
Note! Only the A7M4, A7S3, and A1 have this preset, and other Sony micro-orders do not! Now to say that Sony is straight out is that these three straight out are good, and what A7R4, A7C has nothing to do.
I made a FL-based photo setup myself, straight out is very good, I can produce a film after the liquefaction of the skin.
This is A7M4 straight out jpeg, there is nothing wrong with this color, right?
This one only did the microdermabrasion liquefaction, I haven't even moved the skin tone, this A7M4 straight out of the problem, right?
This is jpeg straight out, in the later stage, as long as the face is brightened, a little skin polishing can be produced. (The face is a little black to prevent overexposure of white clothes)
The straight out of the R6 is probably like this.
This is the RAW original picture and fine-tuning of the R5, I have to say that canon shoot people are indeed metaphysical, and it is very good to adjust it slightly later. But the Sony A7M4 is not inferior at all.
Finally, again, Sony micro single straight out of the color refers to A1, A7S3, A7M4, other Sony micro single or the old way, Sony high probability is impossible to update the firmware for the old model, don't think about it.
Burst
A7M4 in the shooting lossy compression RAW is 10 shots / sec, if it is uncompressed RAW that is 6 frames / s, this is another slot point of A7M4, but the problem is not too big, the loss of RAW is not bad enough, and it is not unusable.
R6 mechanical shutter continuous shooting of 12 shots / sec, electronic shutter continuous shot of 20 shots / s, which can be said to be a hanging A7M4. However, for the vast majority of ordinary enthusiasts, even for some professional photographers, 10 shots / second is enough, so the continuous shooting of A7M4 is not much worse, mainly due to the loss of RAW to achieve 10 frames / s, which is somewhat diaphragm.
Stabilization
Canon's stabilization in the full-frame micro single field is one of the best (and Panasonic have a win-win), and Sony is the lowest.
pixel
R6 pixels may be the biggest problem with this camera, as long as we don't shoot 4K60P all the time, it won't overheat, and the lens group can also be solved by transferring EF, but this 20 million pixels is really unpleasant. Mainly this year's mainstream full-frame camera has achieved 24 million pixels, you R6 must be less than 4 million pixels, but not enough, is simply uncomfortable.
The A7M4's 33 million pixels is relatively reasonable, the A7M4 is cut to the APS-C format and there are 14 million pixels, and the R6 crop to the APS-C format is only 8.5 million pixels, and the gap is reflected.
It seems that the dissatisfaction with R6 is also on the pixel, in fact, 20 million is really enough, but for ordinary consumers", "enough" does not make much sense, who does not like high pixels? Especially R6, which is 4 million less than the mainstream 24 million, enough is enough, it is not very cool.
As for secondary cropping, if you take "pixel low impact secondary cropping" as a reason not to choose these cameras, I think it is a bit exaggerated, there is no need to be unnecessary.
I found a very interesting thing, if you have a camera with a slightly higher pixel in your hand, you basically don't care about the R6's 20 million pixels when you buy a camera, but if you only buy a camera, 20 million pixels is a grudge, hahaha!
Lens group
The native bayonet lens group Canon was hung by Sony, which is why many photography enthusiasts do not want to buy Canon. Full-frame micro single Canon, Sony, Nikon, Panasonic these four, Sony lens group rich we will not say; Although Nikon is expensive, 1.8 fixed focus is really good, in addition to 40F2 and 28 2.8, domestic Yongnuo Wei Zhuoshi is also in addition to Z mouth AF fixed focus; Panasonic 1.8 is cheap and easy to use, and the Sigma L-mouth, the lens group is also rich enough. What about canon RF mouths? The original factory head did not have Nikon conscience, there were few deputy factory heads, and Yongnuo Wei Zhuoshi came out of the RF head but it seemed that there was no news again.
But fortunately, the Focus of the Canon Micro Single Transfer EF Lens is basically not lost, and the adapter ring is less than 300 yuan, which may be the only good news.
Quality control
I have Sony dealer friends, second-hand business friends, I also have a lot of enthusiast friends who bought A7M4, quality control problems A7M4 has more than 10 units, over the years so many micro-orders, on A7M4 problems the highest frequency, do not know how Sony to do, which also led to a lot of people who made up their minds to buy A7M4 began to hesitate.
Budgets in the early 20,000s can buy the A7M4 + Sigma 28-70 2.8 directly. It is said that the offline A7M4 fuselage has fallen below 16,000 (the good culprit of the yen fall, this price is for reference only), if you buy 28-70 2.8 less than 5200 yuan during the 618 period, this configuration is enough for a long time.

But what if this configuration exceeds your budget? Zoom is a must, 28-70 and 28-60 is too bad, 24-70F4ZA is also too bad, may only be able to buy the second-hand Tenglong 28-75 generation, can you accept the second-hand?
R6 only has a combination of 24-105stm + RF50, or replace the RF50 with another fixed focus (this fixed focus is a little too weak).

As the first camera in life, buying it means that it is impossible to change the door in the short term, and it really needs to be carefully considered, especially the two cameras R6 and A7M4 have more obvious advantages and disadvantages, or seriously consider it.
Finally, if you don't take a video, there are many choices in the early 20,000s, why are people now thinking of video photos and double repair?
