I just got the 7artisans 35mm f1.4 lens for my camera. Problem is, the aperture dial on the lens isn't changing aperture but shutter speed. The aperture is just set at f 0. Does anyone have any idea on what might be wrong?

Hi, if its the manual focus one, there is nothing wrong, I guess, there is no electronic contact between lense and camera so camera cannot know aperture. Shutter speed will adjust according to the aperture you chose if in aperture priority mode.

To go along with this, unless the camera is in full manual mode, the “auto” algorithms will notice sensor changes caused by rotating the lens’ aperture ring and make adjustments to other settings, most likely adjustments to the shutter speed. The f-stop is changing, but not being recorded. Try setting the iso and shutter speed manually, you will have to remember what you put the f-stop setting to though.

p.s. Welcome to the forum.

      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!
