Hi,

I am new to this forum and a recent 'convert' to the Fuji X system. I recently purchased a second-hand 10-24mm f/4.0 and while the lens is cosmetically okay and appears optically in good shape, I do have a concern about the OIS. I can see barely any difference between OIS "ON" and OIS "OFF" - both stills (at 1/2 sec) and video. I compared it with my 'kit' lens the 18-55 f/2.8-4.0 and the OIS on the newer 'kit' lens appears much more noticeable.

Is this a normal expectation of the 10-24mm? I am wondering whether to return the lens.

Any comments from the wise would be appreciated!

First of all, the shorter the focal length, the less noticable the impact of OIS. It’s easier to steady a shorter focal length by hand. In order to compare, you need to set both lenses at approx. the same focal length (e.g. 23mm) select an object at 2-3m distance (max.) and make shots with longer shutter speeds. Then you should see similar OIS impact. If not, you could have the 10-24 checked. If you’re a videographer, you could do similar and walk around. OIS should create a steadier motion with less shake. Note that some waivy background in video is ‘normal’ with some Fuji OIS lenses. In fact the new 10-24 MkII is worse in this than the older version.

Thanks Herco for your kind advice.

I have now compared the two lenses (10-24 mm vs 18-55 mm) at 24mm (because this is the narrowest field of view on the 10-24). This confirmed that there was nothing happening at all on the 10-24mm lens. It is strange because the camera body registers the OIS and there is the usual 'whirring' sound if one places the lens to the ear whilst the OIS is operational. Also, when the lens is not active (camera switched off or lens separated from the body), there is a slight rattle if one shakes the lens from side-to-side - this rattle disappears when the lens becomes active.

Your advice really helped - so now it's off to the local Fujifilm Service Centre (Australia) to sample their legendary customer service. I will post an update with the results.

The whirring is normal, it is the OIS working. You also hear it when the OIS switch is in the "OFF" position, it keeps the OIS group parked in a centered position. Maybe that is where your lens malfunctions, keeping it in the parked position.

Thanks mrPeter. I'm guessing that the lens does seem to be able to park the OIS group because the 'rattle' disappears when the lens is powered up.

Interesting there appears to be no information online about how these mechanisms can malfunction. Not that I would want to attempt a repair myself, but it is interesting to know what has gone wrong. Not sure whether Fujifilm Service will explain that though.... Anyway we'll see...

You're welcome PW104. I searched the internet looking for a document that would explain why the whirring does not stop when you switch the OIS "OFF". When I could not find such document I wrote an e-mail to Fuji service in Germany and they answered:

>>unfortunately there is no special articel about this behavior.

The OIS group is a free moving group. So when the camera gives power to the lens
this group gets first centered in position and is then stabilizing the image.
When you switch off the OIS function the motors of the OIS group fix the group in center
position. While keeping it in this position the motors are active and procude a
"working sound". 
 
When you have any further question, please feel free to contact us.<<
 
It shows they are very helpful when you have questions about your Fuji equipment.

Thanks again mrPeter

As you mentioned in your earlier post - it seems that (apart from lack of image stabilization) the symptom of the fault is that the OIS lens group is remaining in the 'parked' position and therefore I guess the cause may be a lack of signal from the lateral vibration detectors to the OIS motors (when the OIS switch is in the 'ON' position. If this is the logical next cause then I think that is where my reasoning may have come to a stop and I'll have to wait for the Fuji service technician to take it further.

    • The backslashes you are referring are just symbols denoting path.  Once you import into these LUTS into Davinci Resolve those backslashes are removed by default and you only see is the true file name which has no backslashes.  Convince yourself of this by opening the LUT folder from the Davinci Resolve Project Settings.  Do you see any backslashes in those LUT names? Of course not.  The only name you see is the one that has the underscores and the periods. These LUTS work as designed without having to change any path names.  However, they need to be set up properly through CSTs and by what is supported in Davinci Resolve.  Hence, the FLog2C film simulation LUTS cannot be used because Davinci Resolve does not support Fuji Gamut color space and the FLog2C gamut. Alternatively, Davinci Resolve does support Flog2 film simulation LUTS because the color space for FLog2 is Rec 2020 and there is an FLog2 gamut. If all you are doing is changing the path names then you are not getting the correct results.
    • I found the reddit topic i refere to :  https://www.reddit.com/r/davinciresolve/comments/1pc3f1e/cant_apply_new_fujifilm_gfx_55_lut/ "Update for y'all, It's just like what @ExpBalSat said, it's because of the backslashes in the names break them. I changed the file name and it works now. "   For me it was the solution. Realy annoying if it doesn’t work for you 😕  
    • Here is the solution to using the Eterna 55 file simulation LUTs in Davinci Resolve.   In general, do not use the FLog2C to film simulation LUTs as they are not supported by Davinci Resolve for two reasons: 1) Davinci Resolve does not support Fuji Gamut Color Space and 2) Davinci Resolve does not support FLog2C gamma.  Instead, use Flog2 which is supported by Davinci Resolve.  Here is an example.  Let's say that you want to use Classic Chrome simulation.  Do the following: Complete your color grade and use a CST to get to Rec 709. Add a node.  Use a CST to convert from Rec 709 to FLog2.  Output Color space is Rec 2020 and Outout Gamut is FLog2. Add a node.  Apply the FLog2 to Classic Chrome LUT Create a combination node from node in steps 2 and 3. Apply a Key to the combination node and adjust the Key Output Gain to get the amount of the combination node that you want applied. So that you do not have to do this over and over again, generate a LUT for the combination node.  Remember to turn off all other nodes before generating the LUT. Hope this helps others. Don  
    • Thanks for the insights. I think it's really hard to make a decision without having the two side by side!
