A Fuji X PRO 1 versus Olympus E-M5 focus speed test.

The recently released Fuji X PRO 1 firmware update increased the autofocus performance. ThePhoBlographer compared it with the superfast AF from the Olympus E-M5. Keep in mind that the E-M5 uses a smaller Four Thirds sensor which also increases the DOF and consequently makes it a bit easier to get things in focus.

  • The test is also not representative because the focal lengths used on the two cameras differ quite a bit. The wide angle used on the Olympus leads to more high frequency detail, making it a lot easier for a contrast AF algorithm to get things in focus.

    • +1, noticed that, too. Makes you wonder just how much this reviewer knows about cameras.

      The speed of the OM-D seems really impressive, though.

      • I’m not sure exactly what the comparison with the OM-D (a known AF speed-freak) was supposed to achieve. I don’t suppose this was meant to be a rigorous or credible test, however. All the criticisms of other reviewers show how far short it would fall if it were.

        If anything, this showed the X-Pro1 as a really fast focusing camera given it was so close to the “fastest”. Finally, the “slow AF” X-Pro1 can be laid to rest. As regards the OM-D, I’m hoping that it was a combination of the rear screen and the video camera, but the 720p version I watched on youtube showed the OM-D’s captured image of the hand as either out of focus or poor IQ or both.

        The focus points used on both cameras were quite large. What would have made it more interesting would have been to choose the smallest spot focusing box, run the test and then check speed and accuracy of focus based on what you were intending. I suspect by the time you have added in second and third attempts to actually achieve the *correct* focus, these 0.1 second focus locks would be suddenly irrelevant.

  • And let’s not forget that Fuji stated that autofocus with the new 18-55 standard zoom should be faster than with any of the current primes.

  • The test should be named: “Look, the EM-5 is still faster”, which, I guess was the intention behind it.

  • Unfair test. A small aperture lens will have the advantage as the focusing does not need to be anywhere near as accurate as a wide aperture prime so tends to be geared for speed rather than accuracy.
    Need to compare 2 similar lenses.

  • Chalk & Cheese test… What a surprise!

    How many other aspects of use could you choose to compare where the Fuji would wipe the floor with the Olympus?

    Anyone can make a biased review… Please try harder

  • Indeed, that’s not exactly scientific.
    For one thing, I don’t see the point of pressing the shutter button that much faster on the Olympus than on the Fuji.

  • Well regardless of the test Fuji really need to make their x mount cameras have class leading focusing especially when they are pitching these cameras as pro and have a price larger then micro 4/3 cameras.

    • not sure there is a huge (if any) price difference between the Fuji XE-1 and the OMD-5 for example…

      • Your right its not massive.

        The prices are quite similar but there is no feature parity other then the fuji having a bigger sensor.

        Six axis image stabilisation is an amazing feature which should be available on all ILC cameras.

        I hope Fuji address these things and really creates features that enable the sensor.

        • In the UK, the OM-D is 33% more expensive than the X-E1 based on the £749 firm pre-order price. In fact, the X-Pro1 is barely more expensive than the OM-D, and with the new offer from Fujifilm to get a free lens, you can effectively get the X-Pro1 body for about £700 (based on the current Amazon prices for the 18mm and 35mm lenses), 30% less than the OM-D.

          I suspect the Olympus will drop to match that in November just in time for Christmas sales.

  • It should also be noted that while Fuji cameras aren’t the quickest at focusing, they aren’t cameras designed to capture quick action either. They’re a more “reflective” type of camera. I know that many would disagree, but speed of focusing is quite secondary to me when using a Fuji. I’m not shooting racing cars with it, I’m shooting street scenes, portraits and landscapes. Accuracy on the other hand is a real issue.On that subject, I thought the X-Pro1′s AF was indeed problematic, more so than on the X100 (properly configured and once you’ve grown accustomed to the way it performs, I have to say that I haven’t missed a shot in a long long time).

  • while using the Olympus:
    “Just as proof we’re going to zoom in…” [picture is out of focus] “..Let’s see that again” [reshoots]

    haha ok.

  • Nice try, but you need to use the same focal length and aperture for a reasonable test. And, you should use a specific subject, instead of just random subjects, to test the accuracy – who cares about speed if it is not accurate.

    Although I am neither a Fuji nor Olympus user, I have tested the AF for both systems in the last few weeks, and I would never buy the OM-D ~ the AF may be quick, but it is highly inaccurate and frustrating for delicate focus shots. For any subject that does not fill the entire focus area (square), the OM-D was terrible ~ it kept focusing on the background instead. For instance, I was trying to take shots of some lavender, and it had great difficulties focusing on the tip of the lavender, even in optimal light conditions.

    If you are just shooting people or large subjects (subjects that fill the entire focusing square), I am sure the OM-D is fine. Though you could say the same for almost any camera. However, as I mentioned, for delicate focus shots, the OM-D’s AF system is terrible. I found the Fuji to be far more accurate and less frustrating, though it may be slower – speed means nothing if it is not accurate.And, considering the OM-D has a 2 times crop factor, it is very weak with respect to depth of field control. Without the low pass filter, the Fuji should have sharper images as well.

    If you are going to perform an AF test, use a specific subject that will show the accuracy as well. This test merely showed speed and did not test the accuracy of the AF system ~ except for the shot of your hand, which was clearly out of focus.

    By the way, I am not trying to be rude and I have nothing against you. I am just tired of biased reviews, especially when they are misleading and insufficient. The OM-D may be a great camera for some people, but it does have some serious AF weaknesses and limitations…

  • That’s one hell of a long black out between shots with the OMD. Meanwhile, with the XPro1 , no black out when using the OVF. You have the option. Clear view of your subject while shooting, Priceless. Just one of many many advantages it has over the OMD. This test is was useless as others have stated.

  • Any kid from kindergarten can do a better comparison test. Stop publishing this crap!

  • Nothing to add here. Simply silly comparing prime vs zoom at different, small/large apertures. Sad that Phobloger used this as a serious comparison. Items should be arrayed close, far, and shot at the same aperture, same focal length.

    It proves, however, that photography blogs are dime a dozen. Subscribe to whichever you will, but gee whiz bangy, this was poor.

    That all said, I can’t imagine the fuji will ever be as fast as the OM-D with any lens.

    For my style of shooting, it will work just fine especially as I don’t use autofocus lenses.

  • The least that they could have done is put an equivalent focal length prime lens (or closest to it) on the Olympus (50mm equivalent which makes it 25mm on the Oly?). In addition, they could have done an equivalent aperture on the Fuji given that it has paper thin DOF at f/1.4 (which this test was done at) and thus making the camera really work on critical focusing, i.e., slower focus. Some shots the Oly was making at f4.5 which is what equivalent aperture with the Fuji’s bigger sensor, f5.6?

    However, I do notice that the shutter throw of the Olympus is shorter than the Fuji. If all things being equal, I would imagine the performance would be quite close, though the Oly would probably still be faster from what it looks like.

    Since the comparison above is apples and oranges anyway, how about the Oly OM-5 against the Nikon 1′s that have instantaneous focus. :o )

  • I just noticed that when he took a shot focused on the kitchen counter, Fuji X Pro 1 shot was beautifully out focused. But OM D was not. But then OM D was with zoom lens. Wonder how the OM D works with prime lenses for bokeh.

  • The smaller the sensor, the lower the quality of blur! Therefore, in response to Jun’s question, the OM-D will not provide you with as much depth of field control as the Fuji, which has a larger sensor (OM-D is 2 times crop factor; whereas, the fuji is 1.5 times crop factor). While you can get bokeh from fast primes on the OM-D, the quality of the blur is not as appealing. In addition, for delicate focus, shallow depth of field shots, the OM-D’s AF system is not very accurate ~ unless the subject fills the entire focus square and there is enough contrast.

    While the OM-D has some great features (in-camera image stabilization, weather sealing, etc) and the image quality has improved compared to older M4/3 cameras, I would never consider getting it due to the small sensor and poor accuracy of the AF system. That said, some people love it ~ it depends on your style of photography and whether you are willing to accept those limitations.

    On the other hand, I would love to buy the Fuji X-E1. However, raw file conversion continues to be an issue. Due to the unique sensor, the raw file conversion software companies (including Adobe) have, so far, failed to convert the files without issues (loss of detail, colour smearing, and artifacts). So, if they do not resolve this issue soon, I will likely be compelled to stick with a DSLR, which is unfortunate.

    Come on Fuji ~ resolve this issue now, so your X-series cameras can meet their full potential and you can increase sales of these cameras considerably. The JPEGs are very impressive, but JPEG is not sufficient for most users…

    • Thanks!!!!
