ISO Accuracy

The actual sensitivity of each indicated ISO is measured using the same shots as are used to measure ISO noise levels, we simply compare the exposure for each shot to the metered light level (using a calibrated Sekonic L-358), middle gray matched. We estimate the accuracy of these results to be +/- 1/6 EV (the margin of error given in the ISO specifications). Note that these tests are based on the sRGB JPEG output of the cameras, in accordance with the Standard Output Sensitivity method defined in ISO 12232:2006, the standard used by camera manufacturers.

By our tests, the X-Pro 1's measured sensitivities are about 1/3 to 1/2 stop lower than marked, which is unusual for a modern camera. This means that for any given light level, shutter speed and aperture the X-Pro1 has to use a higher ISO to get an image of the same brightness as an accurately-rated camera.

Noise and Noise Reduction (JPEG)

Note: this page features our interactive noise comparison widget. By default, we show you the default noise reduction settings of the camera tested, and three other models of the same class. You can select from all available NR options, and from other cameras. The 'tricolor' patches beneath the familiar gray/black/portrait images are taken from the same test chart, and show how noise impacts upon blue, green and red areas of a scene.

ISO range noise comparison

The X-Pro1 does an exceptional job of balancing noise and detail in its JPEG processing, even taking its generous ISO ratings into account. It manages to retain fine detail impressively well at high ISOs where other APS-C cameras are visibly suffering; even at ISO 3200 images looks clean yet detailed. At higher sensitivities low contrast detail progressively degrades, but ISO 6400 is still entirely usable. The two highest settings (12800 and 25600) are only available to JPEG shooters, and here you can see why - they should probably be treated as emergency-only options.

Noise reduction options

The X-Pro offers five noise reduction settings, which cover a good range of options between reducing noise and maintaining detail. Here, for clarity, we're showing the default Standard setting (labeled 'NR 0') and the two extremes, Low (-2) and High (+2). If you want grittier, more detailed output you can set NR to '(-2) Low', while if you're after the smoothest output you can set '(+2) High'. The graphs show little difference at low sensitivities, but begin to diverge at ISO 800. In the crops we can start to see clear differences at ISO 1600, with fine detail being clearly better-retained at lower NR settings.

Raw noise (ACR 7.1 noise reduction set to zero)

Even a cursory glance at this comparison tells you that Adobe Camera Raw's processing of the X-Pro1's files looks radically different compared to its output from conventional Bayer cameras. Chroma noise is strikingly low, and detail retention is impressively high - very much like the camera's JPEGs, in fact. Because of this, direct comparisons have to be treated with a degree of caution - it's best to assume that the demosaicing process of the X-Trans CMOS sensor behaves as though it's doing substantial chroma noise reduction relative to ACR's standard treatment of Bayer sensors. Again we also have to factor in the X-Pro1's over-rating of its ISOs.

That said, the output from the X-Pro1 is remarkably good at high ISOs, and it's difficult to see APS-C Bayer sensor cameras quite matching it at ISO 6400 even with substantial noise reduction applied. In fact the X-Pro1 is giving the full frame Canon EOS 5D Mark III a decent run for its money here. Needless to say, this is very impressive stuff.

I am a rather new member and I must say that the few dopey questions I have asked have usually been answered with great information and a lack of sarcasm and judgement. They were not dopey on purpose. If anyone would like to visit the images in my portfolio you will at least know that I am not just obsessed with cameras but sing them to shoot, share, publish et. So without further ado, just purchased a new Fuji X Pro1 and bam I read the rumor page and it says Fuji X Pro2 verified rumor will be introduced this year. Besides offering the advice, "just shut up and shoot', What would you do? Is this even the right spot to leave my qesriom

Don't worry too much about it.I also just bought the X Pro 1,well aware of the rumors. It's all about IQ right?I can assure you,you wont be disappointed! Far away from it.And I really wonder whether the IQ(mind you, IQ!)will be very different from this one.
All else, yes for sure.

It will take you a bit of effort getting used to the AF of this camera but it's very engaging to use, the VF is great and images are great too.

If you don't shoot action (like sports, pets or running children) you will be ok.

I bought an X-Pro1 a week or so ago - I've got a use for it (I wanted a compact 50 that's not too demanding) and they can be had new for £350 in the UK! Happy days. No doubt a new flagship X-Pro2 will be announced soon, but it'll be a very expensive camera, presumably sitting above the X-T1 in the range.

Fujifilm has fixed most of the reported issues (like slow AF) with incremental updates. I got a chance to review it recently

What is the seemingly insurmountable problem with studying a traditional 35mm film rangefinder and re-engineering it into an equally capable digital rangefinder instead of trying to re-invent the wheel? The idea that you cannot accurately use manual focus is absurd. The whole focusing by wire thing is absurd. Again, why is everyone trying to re-invent the wheel?

looking at these RAW examples the fuji x Pro looks softer nad less saturated than the Fuji X100s

After using one for a while and with the latest firmware I find the camera to be quite superb. Lets face it, most of us are looking for IQ firstly and has been said in the review lenses like the 35 1.4 are second to none in my book.

I just purchased a used X-_pro1 like new in box and I am very curious about the firmware updates that seem to address its previous shortcomings. Should I ask the seller about these because I am naive and no nothing about these on her camera is it a simple fix to update the firmware Your recommendation I don't even know the latest and best ones. or are they available fre e or can they be user updated. and again what is the latest firm ware and how would you perceive this as situation.

The latest firmware update as of May 2015 is version 3.4 and can be downloaded from Fuji's website for free. Also check to see if your lenses are also up to date.

Firstly I really would like to thank almost everyone for the generous and non combative input. So as long as I am curious about one further issue, any gracious input will be devoured with great enjoyment. Some lenses, whether short, medium or full on zooms have O.I.S and some don't. So any other advice on gaining sharpness and stability that works well for you, hardware wise , please let me know because I am well aware of the great impact shutter speed and stillness etc. have. And please take a moment to take a look at my gallery just so you understand that it is images and not equipment I am really hungry for. Thanks in advance, and yeah thanks Light Catcher LT for the real corn on the cob. "things what you are asking do exist and they are called Leica..Really??

OIS helps when the shutter speed gets below 1/60.

Use as wide an aperture as possible and push the ISO up to 6400.

Brace the camera against your face with your left hand under the lens to steady it. A thumb-grip, like the Lensmate, helps as well.

Set the camera to continuous low and learn to fire off two or three shots. many times one will be sharper than the other.

After that, just practice being as smooth as possible while gently pressing the shutter release, I find a screw-in soft release button helps. Also, use a faster SD card like the Sandisk Extreme Pro 95 Mb/s.
