Sony A7R3, Nikon D500 which is accurate and fast?

Let's not just talk about good or bad for the time being, let's take a look at the parameters:

d500, half-frame, 20 million pixels, this failure, a7r3, full-frame, 42 million pixels, win;

D500, focus point 153, A7R3 focus point 425, mirrorless does not have a separate focus module, you can't just look at the number of points, but also look at the number of operations per second, it is considered a tie, D500 is slightly better;

D500 continuous shooting, 10 fps, A7R3, also 10 fps, tie;

The D500 native sensitivity is 51200, and the A7R3 native sensitivity is 32000, because the A7R3 is full-frame, and the pixels are high, winning.

Okay, so you should be able to tell which one is better or worse.

Theoretically, the D500 is more accurate in focusing, as the D500 is a 153-point independent focusing system, of which 99 points are cross-shaped. The A7R3 is a mirrorless camera, so the focusing system is achieved by implanting a special detection pixel on the sensor, which is somewhat similar to a slotted focus point, and may have difficulty focusing in some specific situations. Of course, all of the above is faster phase focusing.

If you consider the slower pure contrast focusing, the accuracy should be comparable, and both are very high.

However, the actual focusing speed of the camera is not only related to the body, but also affected by the lens, and it is very obvious. One of these two machines is a full-width mirrorless, E-mount, and the other is a half-width SLR, F-mount. In other words, it's usually impossible to use the two cameras with the same lens, so there's no way to compare focus.

Although the E-mount can be used to transfer to an F-mount lens, the focusing performance is significantly affected when transferred, and it is difficult to reflect the focusing performance of the body itself.

I can't recommend you to choose the Sony A7, it's more accurate, and it will be faster, but it's higher.

The Nikon DSLR D500 is more accurate and fast.

Which precision should be the first to be more accurate?

Which is the fastest Sony A7R3 or Nikon D500? Of course, the Sony A7R3 is accurate and fast.

Only round shot**, not shot**, in fact, A6400 is enough. Although it is only a half-frame fuselage, its absolute performance is not bad, and the shooting is also very powerful, and the ** of this fuselage is not high, and the cost performance is very high, which meets your use needs, and this choice is actually very suitable.

As for the question of whether you want to upgrade the full-frame machine......If you want to use a full-frame machine, you shouldn't buy a half-frame ...... right nowIt would be a waste ...... thatDirectly start with the full-frame machine to ......

The problem with the source nuclear ridge in the lens ......The 18-105 lens is a half-frame lens, and it is not suitable for a full-frame body like the A7S2 ......It's not bad with a body like the A6400......

Moreover, you choose the A7S2 body with more than 10,000 yuan, but only give it a lens of more than 3,000 yuan, which is the ...... of the upside-down configurationFor interchangeable-lens cameras, the lens is more important than the body, and it should be equipped with a higher-end lens!

In fact, it doesn't matter if the calendar cover is not full, the full picture banquet is only more concerned about taking pictures, **It is not necessarily the more blurred, the better, but**The explanation point environment is better The advantage of the truncated frame is that the lens is small The body is small This is conducive to shooting, but to shoot** A7S2 is better than A6400 The most obvious is the high sense In fact, if you like A6400 and are afraid of wanting full frame in the future, you can give 6400 a full-frame lens, Sony lenses are universal.

Perhaps A6400 is more suitable for shooting**, although it is a frame cutting machine, but it is its advantage that there is no cutting jujube Zheng Che super-sampling. The jelly effect is also low. Most of the 4K60P images on the full-picture bench are cropped.

Both models can be used daily, if you want to enter the fixed focal macro in the later stage, D5300 is more suitable than A6000 in terms of optional range and cost, A6000 currently has fewer lens options, and they are more expensive, there seems to be no macro lens. Compared with D5300, although the performance is slightly weaker, the biggest advantage of A6000 is portability, please weigh it up.

The biggest hit in recent times is none other than Sony's most ** full-frame mirrorless A7RIII, among which the official publicity of the 15 levels of tolerance is also quite interesting. The latest DPRew test shows that the Sony A7RIII forgiveness is about half a stop higher than that of the previous generation, thanks to the reduction of the sensor noise floor to make the shadow part more pure. However, compared to the Nikon D850, which is also known for its ultra-high latitude, the Sony A7RIII is slightly better than the Nikon D850 at the same ISO100 and slightly lower than the D850 at its ISO64 base sensitivity.

Previously, Sony's claim of 15 stops of latitude should be A7RIII equivalent to the value of 800W pixels,This algorithm can compensate for the disadvantages of high-pixel machines in the tolerance test,And the value of this test is only close to 15,So the official use of "about 15 stops" is not a mistake。

There are many indicators for image quality evaluation, and the indicators about color performance are very subjective, so it is impossible to give an absolute result.

Compared with these two machines, it can only be said that they have their own characteristics ......Which one is better depends on personal preference.
