Hello,

I've just received a brand new GF 120mm F4 OIS and wonder if any owners of same have encountered the following"

Set the GFX 50s to manual focus, turn off OIS on the lens and you can still hear the lens motor chirping or singing intermittently, as if it is hunting for something.  Is this normal?  The OIS switch appears to work in terms of activating and defeating actual image stabilization, but turning it off seems to have no effect on the sound? Clearly, some motorized aspect of the lens remains active at all times, but for what purpose?

This is a reply to my own post:

Fujifilm was kind enough to reply to my email, and apparently the noise is normal.  The linear focus motors remain active in all states, and that includes when the camera is set to manual focus.

 

I might add that the 120mm OIS is incredibly sharp.  The OIS is the best that I have encountered, and I have been able to capture handheld images at a 30th of second that remain sharp.  Totally amazing.

I was thinking the same about the 110mm lens I just got with regard to sharpness. What about battery life? When I switch off, there is still info shown on the secondary top LCD. I wonder what sort of drain that has on the battery?

My understanding is that the LCD on the top plate is E-Ink and uses very little energy.

      LUT doesn't works on resolve

      By Don Barar · Posted

      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!
