They rate ISO by a different standard, use a non-standard Color Filter Array (CFA), and their RAW files rely on proprietary metadata to correct exposure levels (which 3rd party RAW processors may ignore). In my eyes, the best performing camera is the Fujifilm X-H1, which shows less color noise and more pleasing grain. The imaging sensor sits in the middle of your digital camera, right behind the lens, and turns the optical image into a digital version, converting light into electronic signals. Digital Cameras Fujifilm is one of the best regarded camera brands worldwide. The X-Trans sensor in most of Fuji cameras does not use a Bayer matrix, but rather a very different matrix whose pixels are arranged in rows of three colors — a technology inspired by the naturally irregular distribution of silver halide crystals on film. The third mode of operation for the EXR sensor uses variable photosite sensitivity to greatly extend dynamic range. Still today, Bayer sensor cameras show more moiré than X-Trans cameras (including the 50MP Fujifilm GFX 50S), but I think that once APS-C cameras will go beyond 30MP and Medium Format reach 100 Megapixel with the Fujifilm GFX 100S, one of the advantages of X-Trans cameras (less moiré) will become almost negligible. So perhaps what Fujifilm really meant to say is that X-Trans demosaicking is 30% as efficient as Bayer. However, the other possibility is the new update to the Fujifilm GFX line, complete with a 102MP sensor. But X-Trans is not only about less moiré. These color filters also have the effect of increasing the resolution so, when shooting with a high-resolution Fujinon lens, the camera delivers images with a perceived resolution far greater than the actual number of pixels used. There are many situations where a recipe is 99% compatible. With a monochrome subject, the extra green in the X-Trans pattern is supposed to produce a perceived higher fidelity result than Bayer. In this guide, I’ve attempted to cut through all the noise, and offer my recommendations of the top 9 Fuji cameras in 2020. Where the best Bayer cameras can now capture useful images at ISO 1600, 3200, or even higher, the Foveon sensor is best at lower ISOs. X-Trans was developed by Fuji because Fuji always do their own thing as far as sensors are concerned. Bayer sensors are more colourful. Now the moiré is significantly attenuated. So for those people, who refuse to read the article and don’t go beyond the headline, I will at least make a bullet-point list, in the hope they will read that one at least. The X-Trans 4 sensor is able to gather considerably more light than the sensor on the X-T2, or any other APS-C Fuji mirrorless camera. When it comes to image quality, the resolution remains unchanged at 24-megapixels. But Bayer sensor cameras like Olympus cameras have this issue too, both the flare and the grid. The new Fujifilm GFX will be an incremental update to Fujifilm GFX100. DCRaw is used for all demosaicking because it conveniently allows us to provide our own raw pixel data without having to wrap it in a container. Per saperne di più su quello che stiamo facendo. Especially since Full Frame is cheap nowadays. Down below you see a comparison between the Sony A6500, Fujifilm X-A5 and Fujifilm X-H1 at ISO6400 (RAW). According to rumor website Fuji Rumors, there are two possible cameras that they are expecting it to be. Above left is the standard "Bayer" color filter array pattern used by most cameras' sensors, with the yellow outlines indicating the two-by-two pixel grid on which the array is repeated. http://www.artoftheimage.com - Fuji X-T100 - Is the NON - X Trans Sensor a POSITIVE Thing? Predictably, AA-filterless Bayer and X-Trans suffer from similar levels of false color, X-Trans being slightly worse/chunkier due to the courser pattern. Bring on the magic! It’s just a larger pattern, 6×6 vs Bayer’s 2×2. FUJI's X-Trans-Sensor im Vergleich zu Bayer-Matrix und Foveon rkphoto_art. By using a technique designed to treat color noise to treat both color noise and false color (which have similar appearance but different causes), fine and especially subtle color variations are lost, even in low noise, low ISO images. Sony and Nikon files have the Bayer color pattern. Fujifilm X30 – 1/1000 sec., F/2, ISO 100 – Clicca per ingrandire Conclusioni. I think we can do better than charts though, let’s try a subject where one typically encounters moiré in the real world: fabric. documents). Without XTRANS technology, I'd toss all my Fuji stuff in the garbage and go back to Full Frame. Why? Even though X-Trans lost the battle, the results were very close. X-Trans tends to produce line-like artifacts, appearing smeared in aggregate, whereas Bayer produces more speckle-like artifacts. One thing though: because the X-T1 doesn’t use a standard Bayer pattern on the sensor, RAW converters often don’t do a good job with them. Here is an illustration of a traditional bayer pattern color filter array compared to the new Fuji color filter array: Top image: 1) Lens, 2) Sensor, 3) Optical low-pass filter. Since the introduction of the Fujifilm X-Series line of cameras, reviewers and consumers have struggled to compare them directly to the competition. Because Fujifilm’s own X-Trans demosaicking algorithm is proprietary, it could not be used for this comparison. In combination with newly introduced three-way tilting LCD monitor and high resolution and high magnification (0.62x) organic EL electronic viewfinder, the FUJIFILM X-T100 is versatile, reliable and the ideal companion for executing creativity. One well-known lens and camera metrics company has declined to even attempt any comparison against Fujifilm X Series cameras. So, for me and my personal needs, the only real remaining advantage of going Bayer would be that the cameras would be cheaper (and that’s a HUGE advantage). This came after a long pause in availability of interchangeable lens cameras from Fujifilm (they made Nikon F-mount DSLRs in the 90’s and early 00’s). Here Fujifilm elaborates on the claim that APS-C X-Trans can match the performance of full-frame (presumably higher resolution as stated above) Bayer: The FUJIFILM X-M1 is equipped with a large APS-C X-Trans CMOS Sensor, which offers picture quality comparable to that of full-frame sensors. The poor performance of X-Trans on Example 4 is more interesting. Explore the world of FUJIFILM's X Series and GFX mirrorless digital cameras. PSNR is a standard measurement for quantifying image degradation. Utilising unique colour science technology developed over the past 80 years and the largest system of dedicated APS-C lenses, FUJIFILM helps you to spend more time shooting and less time fixing your images afterwards. Also, keep in mind that lab tests at imaging-resource for example, are made using different lenses on different cameras. Huh. I know some lab tests show better sharpness results for Fujifilm’s Bayer cameras X-A1, X-A2, X-A3, X-A5 and X-T100 over the X-H1 or X-T2, but we already explained back in 2013 why it is like this. Any apparent larger noise advantage found in other comparisons must be due the confounding factors of underlying sensor technology (Sony makes the sensors, FYI), ISO rating, electronic/thermal noise, and noise reduction baked in to the X-Trans demosaicking algorithm in use. The reality is that the false colors wash out this supposed advantage and it actually performs worse.
