Measuring Nikon D750 Image Quality with Quan Huafu SLR with Balanced Performance

IT 168' s evaluation of the release of Nikon D750 can be said to have earned enough attention. Many people also said that this Quan Huafu SLR camera beat Canon 5D3 in function and cost performance. From the perspective of cost performance, Nikon D750 does have the strength to compete with Canon 5D3. Nikon D750 is a lightweight FX product, which has many function points in D8 10 and D4S dispersion. In addition to the decentralization function of high-end machines, Nikon D750 has also added many popular flip screens and Wi-Fi functions. In short, Nikon has put a lot of effort into this product. Look at the quotation13,500 yuan, ranging from D6 10 to D8 10. It has become Nikon's most popular Quan Huafu SLR. Then the question is coming! What's the picture quality of Nikon D750?

Nikon D750 uses a CMOS sensor with 24.32 million pixels. Nikon's sensor is very competitive among Quan Huafu sensors in terms of tolerance and high noise control performance, but it does not use low-pass to enhance the detail performance. I don't know whether to reserve space for future upgrades. (PS: Nikon D750 is the second speed-oriented Quan Huafu machine after D4S, so it doesn't use ultra-high pixels like D8 10. ) The processor of Nikon D750 is a brand-new EXPEED 4 processor, and the next step is our real shot verification process.

Resolution real shot test: it is obviously better than D6 10 by naked eyes.

Nikon D750 and D6 10 use the same 24 megapixel sensor. The difference is that the processor of Nikon D750 is the latest EXPEED 4 processor, while Nikon D6 10 is the EXPEED 3 processor. This resolution test and subsequent resolution tests will have an impact on this difference. As we all know, the three major factors that affect image quality are sensors, processors and lenses. Nikon D750 adopts a new processor, and theoretically the image quality will definitely exceed D6 10, which is also Quan Huafu.

Under the strict evaluation environment, we used Nikon D750 and D6 10 with 50mm F 1.4G to take the indoor proofs in the following figure, and enlarged the four partial screenshots by 100%.

From the test, the details of Nikon D750 are excellent, and the metal texture in the first screenshot is restored accurately, not to mention the details in the second and third screenshots. The final multicolor details are also "vivid". Nikon D6 10 lost to D750.

Analysis and summary: From the initial metallic texture to the final color details, every screenshot detail of 100% is visible to the naked eye. It can be seen that Nikon D750 is better than D6 10, which is due to the effect brought by the brand-new EXPEED 4 image processor and high pixel sensor. Nikon D6 10 has better resolution performance than Canon EOS 6D in previous comparative tests, and Nikon D750 can compete with Canon 5D3 in resolution performance.

High sensitivity real shot test: the performance is much higher than D6 10-ISO 3200 available.

The common sensitivity range of Nikon D750 camera is ISO 100 to ISO 12800. It can be extended to ISO50 downward and ISO5 1200 upward. Nikon D750 is equipped with Nikon's latest EXPEED 4 image processor, which can effectively reduce noise at high sensitivity. Nikon has four noise reduction options, namely high, standard, low and off. We will test the photosensitive effects of Nikon D750 and Nikon D6 10 under these four conditions respectively.

The first is to turn off the sensitivity test comparison under noise reduction.

When the noise reduction function is off, Nikon D750 can be used under ISO 1600. Even so, it is much better than Nikon D6 10, which is equivalent to the performance of D6 10 in ISO800. Nikon D750 was a little noisy at the beginning of ISO800, but the details were still good. Nikon D750 turns off noise reduction, and the extreme high sensitivity is ISO6400.

Secondly, the sensitivity test comparison under the condition of low noise reduction.

In the case of low noise reduction, the sensitivity of Nikon D750 is ISO3200, but the details are obviously more than that of turning off noise reduction, and the noise is less. On the other hand, Nikon D6 10 is basically only half the level of D750.

Then, the sensitivity test is compared under the standard noise reduction condition.

Standard noise reduction is the most commonly used noise reduction mode of Nikon SLR. I believe many people are more concerned about this. We can tell you for sure that the available sensitivity is still in ISO3200. In ISO6400, there is not much noise, and retaining details is equivalent to closing ISO800 under noise reduction. At the unexpanded maximum sensitivity of ISO 12800, there is not much noise. This is not only an emergency, but also can be used directly when shooting hand-held night scenes.

Finally, the sensitivity test comparison under the condition of high noise reduction.

In the case of high noise reduction, many details are worn off when watching ISO800, but also in this high noise reduction mode, the photos taken by Nikon D750 under non-extended sensitivity can be used, so it can be said that there is no need to worry about the night scene at all. From this degree of noise reduction, the optimization of image processor has played a lot of roles.

Summary of high sensitivity test: The excellent performance of Nikon D750 has a lot to do with the latest EXPEED 4 image processor effectively reducing noise at high sensitivity. If you still use the old image processor, the high-sensitivity image quality may be the same as Nikon D6 10. In this way, the high sense of victory also gives Nikon D750 enough evidence to locate higher than D6 10. In short, the performance of Nikon D750 in high sensitivity can no longer follow the legacy of "master photographer" that Nikon has good resolution and Canon has good high sensitivity.

Summary of full-text image quality: Nikon D750 is much higher than D6 10 from resolution to high sensitivity test. Moreover, from the test results of its high sensitivity and resolution, it does confirm what many netizens said: "Its image quality and comprehensive strength can be comparable to that of Canon 5D3". If you are currently interested in buying a Quan Huafu SLR camera, please consider this D750 with full functions and excellent image quality.

In addition, the operation of Nikon D750 can be seen in this article "Hands-on Experience of Nikon D750 with Comprehensive Strength", and we will produce more relevant tests of D750 later. Please continue to pay attention to the channel dynamics of IT 168 digital cameras.
