This price is the lowest among several popular Quan Huafu SLR models (D600/D700/5D2), and it is worth buying by many users. However, many users suffer from the lack of objective third-party evaluation and comparison, and cannot make choices by reference. They dare not make a move for a long time. I hope that a series of 6D evaluations provided by IT 168 can solve your distress.
Resolution test: enough pixels; The resolution is better than 5D2, but slightly worse than D600 in RAW format.
The effective pixel number of Canon 6D is 20.2 million. In my opinion, 20 million pixels is enough, which can not only bring high picture resolution, but also meet the general output requirements, and the high sensitivity performance will not be too bad. It is a relatively balanced choice.
In the resolution test, we used Canon 6D equipped with EF50 1.4 lens to shoot the sample of ISO 12233 resolution target (4000 lines) at various apertures, and tested it by Imatest software, and finally got the resolution values at various apertures. The test results are as follows:
▲EOS 6D resolution test results
Among the 4000 lines, the performance of JPG straight out in 6 days is the best, and the performance of nearly 3600 lines has been excellent, and the resolution from RAW to JPG is higher than that of straight out. Therefore, shooting in RAW format and then converting to JPG can record more details. For photos with high quality requirements, you may wish to shoot in RAW format.
Without comparison, there is no good or bad, after all, full of various evaluations? Good, good, good, enough? In the new era, what we want to see more is a well-founded conclusion that can really guide us. Therefore, the author chooses the best-selling Quan Huafu SLR at the same price, and compares the resolution with Canon 6D in the same environment, so as to provide some data reference for users who can't buy better products.
▲ Resolution contrast test
By comparison, it can be found that the resolution of 6D even exceeds D600 when JPG is straight out; In the case of RAW to JPG, it is also much better than 5D2, but slightly worse than 600, and it looks excellent as a whole. After all, 5D2 is the model of several years ago, and the hardware and algorithm are out of date. In this link, it can be compared with D600 and 6D.
In fact, high pixels may not bring high-resolution performance, but also depends on the lens. In the case that most of the lenses are not updated, the existing 20-megapixel body is enough.
Take Nikon as an example, most zoom lenses are equipped with D800, the top pixel volume test, and the best resolution is only about 3,800 lines (1.4G can exceed 4,000 lines after several fixed-focus tests). The reason for this result is simple: the detail performance of photo sharpness is restricted by two main factors: the pixel of camera body and the resolution of lens. Considering that the resolution of most existing lenses is limited, the pixels with too high camera body may not be useful (only a few high-resolution lenses can give full play to the advantages of camera body pixels), but the high-sensitivity performance will be affected by the dense pixels.
From this point of view, for users who do not require large-scale printing, 6D20.2 million effective pixels can fully exert the resolution of most zoom lenses and a few fixed focus, which is completely sufficient.

Comprehensive high sensitivity performance: Canon 6D>；; Nikon D600 & gt Canon 5D2, ISO6400 fully equipped.
The effective pixel of Canon 6D is 20.2 million, which is lower than D600(2426 million) and even worse than 5d 2(2 165438+ million). Under the condition of the same sensor size, the lower pixels per inch will theoretically make the camera have better high sensitivity performance. Prior to this, some high-sensitivity samples were posted on foreign websites, and the high-sensitivity performance of 6D should be good. But I believe what people want to know more is what is 6D high sense? Not bad? To what extent? Under the same environment and settings, which is better, D600/5D2?
So, the following slice may be what you want to see:
▲JPG Direct Out high sensitivity slice comparison
It is not difficult to see that the performance of 6D2 is better than that of D600 and 5D2 (5D2 has a strong sense of tailing, and the algorithm has to sacrifice details for noise reduction), and the overall noise reduction of 5D2 is worse than that of D600. The author thinks that 6D can reach 6400 with ISO. The most prominent is the suppression of color noise, which is basically invisible under high ISO.
Considering the differences of built-in algorithms, the high sensitivity level of JPG does not represent the high sensitivity performance when the camera actually records the picture. To this end, the author also made a set of ISO local enlarged slices by converting the RAW file into JPG for comparison.
▲ Comparison of high-sensitivity slices from RAW to JPG
In the comparison of high-sensitivity slices from RAW to JPG, we found that the advantage of 6D is very obvious, which can reach 12800 with ISO, while D600 has obvious noise in ISO6400 and 5D2 has obvious noise in ISO3200.
In terms of high sense alone, 6D is undoubtedly the best of the three SLR models, and its advantages are very obvious.
Indoor low-light real shooting experience: using standard noise reduction JPG straight out, ISO6400 picture is still clear.
Theoretical data need to be combined with practice more often to be meaningful. The high-sensitivity contrast of local slices can explain some problems, but it can't represent the overall image quality level of machine shooting. We still need to shoot real scenes to observe the whole picture to fully understand the high sensitivity of 6D. In this regard, our IT 168 editor took 6D to shoot a series of indoor low-light lenses and felt the high sensitivity level of 6D.
All photos are taken with the default factory settings (standard noise reduction), and JPG is straight out. I believe it has certain reference value for users who want to know the effect of 6D real shooting.

"High sense summary:
The high sense of 6D is excellent in both the slice contrast and the overall picture effect of real shooting. Although the performance of high sensitivity is expected to be better because of the lower pixels, it is beyond the author's expectation to be so excellent. Undoubtedly, among the three best-selling entry-level SLR, 6D's high sensitivity performance is the most outstanding. ${PageNumber}
Editor's point of view: There are enough pixels, excellent high sense and comprehensive image quality, which is the king of the best-selling entry-level Quan Huafu SLR.
Through evaluation and real shooting experience in various environments, the cheapest Quan Huafu SLR Canon 6D impressed me the most: excellent high-sensitivity performance and JPG direct resolution performance are also the best. It doesn't matter if the pixels are less than 5D2/D600. After all, 20.2 million effective pixels is enough.
Pixels are more often a trade-off between resolution and high sensitivity. From this point of view, I personally think that the overall picture quality of 6D may not be the best in the entry-level Quan Huafu SLR, but it is definitely the most balanced: there are enough pixels, outstanding resolution and high sensitivity.
Canon 6D's detailed evaluation of image quality has ended. In addition to the image quality, the appearance, feel, control and additional functions of the machine are also important factors for our users to purchase. In addition, the Wi-Fi module equipped by Canon 6D is also a highlight.
Please continue to pay attention to the IT 168 digital video channel (Weibo @IT 168 digital video). Later, we will provide a detailed evaluation of Canon 6D appearance control, so stay tuned!
