Well, as we discovered in the first article of this series, the in-camera processing does more than just demosaic the image, it also applies heavy chroma noise reduction and color profiles which reduce overall saturation (these are called Film Simulations by Fujifilm). Bottom image: 1) Lens, 2) Sensor, 3) Natural random arrangement of the fine grains of silver halide in film. I also bought a smaller secondary Fuji camera called the X-A2. That means you can get better IQ by buying a low-end camera (X-A3) that costs a third what the high-end model (X-T2) does — from the same manufacturer (although you won’t necessarily get better JPEGs if the level of chroma NR being applied in-camera is the same in the X-A line). Well, that’s more like it. With two model line exceptions (i.e. The X-T200 employs a very similar APS-C Bayer sensor to the X-T100, now with copper wiring for better image quality and performance. This spell has a catch! Disclaimer: Fujirumors has no affiliation with any of the equipment manufacturers mentioned on this site. However, the other possibility is the new update to the Fujifilm GFX line, complete with a 102MP sensor. There is no evidence of “dramatically boosted resolving power.”. The XF10 is certainly one of the smallest compact cameras to have an APS-C size sensor, and although it’s a traditional Bayer design instead of Fuji’s legendary X-Trans sensor design, the image quality is impressive. Got a rumor or news to share for FujiRumors? As you can plainly see for yourself in the above figure, there’s absolutely nothing random about the X-Trans CFA. In order to test this, we generate a noise image and apply the very same noise image to the raw Bayer and X-Trans data before demosaicking, which simulates how noise occurs in a sensor. 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. 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. Fuji’s X-Trans sensor is unique in that it uses a custom layout for detecting colour on its sensor. A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors. Fuji X-E1 / X-E2 :: As you can see, this is the class of X series camera that I do not own. X-Trans was developed by Fuji because Fuji always do their own thing as far as sensors are concerned. Because Fujifilm’s own X-Trans demosaicking algorithm is proprietary, it could not be used for this comparison. The Sigma “microcontrast” would be far superior to the Fuji — but the Fuji would be better than a Bayer because of the X-Trans sensor layout. This is because there are fewer red and blue sites in the X-Trans pattern compared to Bayer. 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. However, I’ve done tests and found that this algorithm is at least as good as (and perhaps better than) Fujifilm’s. Ricordo che il sensore fuji è un sensore standard sony, ... An AA-filterless Bayer sensor and an X-Trans sensor of the same resolution are fairly evenly matched." The Fuji X Weekly app has the ability, for Patrons, to filter by Camera or Sensor. http://www.artoftheimage.com - Fuji X-T100 - Is the NON - X Trans Sensor a POSITIVE Thing? A Fuji filter is composed of 3x3 matrices with four green cells in … First and foremost, let me say that I LOVE X-TRANS. For instance, you cannot use the RAW files directly in DeepSkyStacker. Why? A good 4K is all I need, maybe with full sensor readout (no line skipping and no crop), Fujifilm cameras are already small enough for my taste (I own and X-E3, which is a compact powerhorse. Fujifilm X-H1 (APS-C 24MP) Vs. Sony A7rIII (FF 42MP) Vs. Canon 5DsR (FF 50MP) Vs. Nikon D850 (FF 45 MP), Fujifilm X-H1 (APS-C 24MP) Vs. Sony A6300 (APS-C 24MP). Digital Cameras Fujifilm is one of the best regarded camera brands worldwide. Fujifilm claims resistance to dust, moisture and cold temperatures down to -10˚C while Sony only mentions dust and m… Think Super CCD on the early S series ILC that in all other respects were basically rebadged bayer sensor Nikons or EXR in cameras like the X10 for example. But probably it is possible to patch the header of a RAW file of a Fuji camera with the same sensor generation i.e. It might seem most obvious to pick your camera, but that might not be the best choice. Nevertheless, in our testing of previous Fujifilm Bayer-sensor cameras, the image quality remains very high, with lots of detail and excellent high ISO performance for this sensor size. I would say this is true. The preceding tests were conducted with images containing essentially no noise. The filter pattern is 50% green, 25% red and 25% blue, hence is also called BGGR, RGBG, GRGB, or RGGB. Subscribe to our Newsletter! With a monochrome subject, the extra green in the X-Trans pattern is supposed to produce a perceived higher fidelity result than Bayer. Can you see the difference? The bigger the number, the higher the fidelity. And let’s take a look at that moiré target with a simulated AA filter: Now let’s compare our simulated AA-filter Bayer output to X-Trans. Fujifilm claims that this layout can minimise moiré effects, and in turn increase resolution by eliminating the need for a low-pass filter. Bayer sensors are more colourful. By all accounts this is the Sony sensor that is used by many cameras, including most significantly for me, by Leica in all their APS-C X and T series cameras. firstname.lastname@example.org. As well as Fujifilm’s continuous improvement philosophy (‘kaizen’) of providing consistent firmware updates to keep their existing product line competitive, they also have a habit of releasing plenty of cameras and accessories each year!. , DPReview says that the 16 MP X-T1 effective resolution is not much lower than 24MP, due to the virtues of the X-Trans sensor, as well as less color noise and moiré, we already explained back in 2013 why it is like this, using larger heat sinks on the Fujifilm X-H1, Fujifilm tried to put the X-TransIII sensor into the small X70, less moiré (an advantage that will become negligible once APS-C sensor go beyond 30MP), sharper compared to cameras with same pixel number and optical low pass filter, unless the processing in camera is very aggressive, like on X-A5 and X-T100, more pleasing “film-like” grain at high ISO, 20%-30% less processing power required (possible benefits listed below), Bayer is better for features and speed, unless Fujifilm can compensate for the extra 20-30% processing power required by the X-Trans sensor with a more powerful processor (present in Fujifilm X-T3), new sensor tech for faster sensor readout (maybe stacked sensor) and better heat management (present in X-H1), more pleasing (some say “film-like”) looking grain at high ISO, 24/26 Megapixel are more than enough for my photography, no need to have 30MP+, Zebra & Co could be implemented using a new and more powerful processor (available on the Fujifilm X-T3), I don’t need 8K video. Content Copyright It’s also of the same vintage from 4 years ago. Some Fuji fanboys prefer cameras with the X-Trans sensor (also developed by Fuji), which is used on other models, but the X-Trans sensor is great for 'artistic' photos, but I find them too grey and moody. To eliminate this, an anti-aliasing (or optical low pass filter) filter is fitted. Later that evening, after blue hour, I did a quick test of both cameras. As you can see, the difference between the two is quite big. If we compare it to the A7 III, the Fuji is larger but lighter. X-Trans provided a marginally higher PSNR than Bayer in the presence of noise (the results are so close that things like a different choice of Bayer algorithm, JPEG compression, and certainly any application of NR would wipe out the differences). Fujifilm cameras are broadly categorised into X-system and GFX-system. A7 III: 126.9 x 95.6 x 73.7mm, 650g Weather-sealing is available on both products. As an Amazon Associate I earn from qualifying purchases. This happens because the chroma NR strength required to eliminate moiré, which is, in-camera, naively applied to all images, regardless of the actual presence of moiré, is much greater than the chroma NR strength required to eliminate chroma noise. Well,as if Fuji doesnt have enough different models to choose from in their X mount range,here comes another form factor. Everyone can clearly see the Bayer sensor is much better at resolving detail and fine patterns and X-Trans is simply worst, even though both are Fuji cameras and the X-T3 (26 MP X-Trans) costs much more compared to the X-A7 (24 MP Bayer). Fujifilm also makes a series of lower-cost cameras that use Bayer sensors like you find in most other DSLRs. When it comes to image quality, the resolution remains unchanged at 24-megapixels. The two cameras feature an APS-C sized sensor. I had both cameras with me when I was out testing my super-wide lens. Using X-Trans didn’t buy us anything. Ah, there we go. No noise reduction or desaturation is required. 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. Fujifilm representatives have tossed around various figures of their own for X-Trans performance (“30% slower”) and have also hinted that one of the reasons they choose Bayer for their new medium format GFX 50S camera was because demosaicking 50 megapixel X-Trans images would be too slow. The pattern repeats to fill the sensor, with the same orientation for each 2x2 cell. Home Blog About Fuji cameras, x-trans sensors and RAW processing. The sensor in the X-T1 is capable of some awesome low-light performance, but the 6D’s larger size will give it an advantage. But the fact that I love X-Trans, does not prevent me from discussing the big Bayer Vs. X-Trans debate, that has recently been fueled again by DPReviewTV in the X-T100 review and Tony Northrup in his X-H1 review, in the most objective way as possible. And it’s not me, a fanboy, saying it, but DPReivew’s own lab test. The new Fujifilm GFX will be an incremental update to Fujifilm GFX100. Well, the moiré/false color certainly looks different. Let’s see if that’s true. Fujifilm Manager Toshihisa Iida said it clearly this interview of 2017: the next generation APS-C sensors will still be X-Trans. Let me explain. The more expensive X-T30 is the first model in the current Fujifilm range to feature the company's unique X-Trans sensor, which Fujifilm claims offers better image quality, so that's an important difference to the cheaper X-T200 if you're considering both models. I used to own an X-E1. They all look crusty as a Leprechaun’s corduroys on St. Patrick’s Day. The reality is that the false colors wash out this supposed advantage and it actually performs worse. With our award-winning range of cameras suited to Pros and enthusiasts alike, we're sure there's a … In this guide, I’ve attempted to cut through all the noise, and offer my recommendations of the top 9 Fuji cameras in 2020. I prefer the grain at high ISO of camera number.... Fujifilm X-A5 (Nr 1), Fujifilm X-H1 (Nr.2) Sony A6500 (Nr.3). Fujifilm X30 – 1/1000 sec., F/2, ISO 100 – Clicca per ingrandire Conclusioni. I also bought a smaller secondary Fuji camera called the X-A2. 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. Poof. From looking at the difference image, it seems likely that if AHD were doing a better job interpolating the near-diagonal lines in Example 2, it would have won across the board. Well, so much for that… This example looks far worse with X-Trans! 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. documents). (Leprechauns are magical right?) An AA filter, however, does nothing to help with noise, which happens in the sensor, so false colors introduced by high ISOs (as in the noise examples above) are unaffected. And you have to define the source with “Source: Fujirumors.com” (working link). This reduces sharpness and the amount of light that the sensor is sensitive too. But I’d lose the more “film-like” grain and less color noise at high ISO (as well as better moiré control, at least until APS-C goes beyond 30MP). Just different, still patterns — neither are random. L’X-Trans è certamente un sensore innovativo e rivoluzionario, che avvicina non poco la fotografia digitale a quella analogica in termini di resa. Fujifilm’s is a tightly integrated system, wherein everything is a little bit different. Now I ask you, should Fujifilm stick with X-Trans also after the Fujifilm X-T3 or go all-in with Bayer? This is what raw data from a sensor with a Bayer and an X-Trans CFA looks like, respectively, before demosaicking:This methodology allows for a direct comparison of the output with the input images (ground truth), and is the same technique employed by the researchers wh… There are better algorithms available for Bayer, but this is the best DCraw supports. The X-Trans pattern changes the character of moiré, but does not appreciably reduce it, and certainly doesn’t eliminate it. The sensor’s unique colour filter array minimises moiré and chromatic aberration without the need for an optical low pass filter, while dramatically boosting resolving power even at identical pixel counts to deliver sharp and texture-rich pictures. So there you have it: We disenchanted the marketing copy, saw through the legerdemain, traced the rainbow back to its very source, and found the truth about X-Trans. Sensor. As we know, Fujifilm recently registered three cameras: FF190001 = X-A7 FF190002 = X-Pro3 FF190003 = ? (Note that the input image is completely monochrome.). I am merely trying to test if the X-Trans sensor is a good or a bad thing. The effect of all these confounding factors, intentional or not, along with Fujifilm’s hyperbolic and cryptic marketing copy, has been to lead consumers to draw incorrect conclusions when comparing Fujifilm against other brands of camera, specifically regarding noise, moiré, and detail resolution. instax instax mini Link. In this time of evolving full-frame cameras with new features that increase the automation of “capturing an image” perhaps it is useful to very briefly review the reasons why those who use a camera with a different sensor continue to believe that a slower and more deliberate workflow has advantages. And if you have no problems using other converters, just get Capture One, Iridient & others, who do a better job pulling out the best of the X-Trans sensor with no need of extra editing steps. Without XTRANS technology, I'd toss all my Fuji stuff in the garbage and go back to Full Frame. The fact is, some patterns and orientations will look better with Bayer and some will look better with X-Trans.
