Nope that is not normal -- appears to be an artifact of the CFA. Is this a camera generated JPEG or a JPEG from a processed raw file and if so from what software?

I converted my RAW through Adobe RAW converter and then I have it opened in Lightroom. Should I use a updated Lightroom(like Adobe cc) to process my RAW files from now on?

 

Don't really know what is wrong yet. Next step is to let someone else examine that raw file. Open a free Dropbox account and upload the raw file. Then place a link to the raw file here. I have multiple RAF capable raw converters -- take a look for you.

I don’t understand, what I see is a few darker blobs, is this not simply dirt on your sensor?

 

Take a picture of a white surface and enhance contrast if you see black globules it’s dirt otherwise it is something else

I mainly use Adobe DNG converter and I just double checked my converter is capable for X100F. Do you guys think I should use that RAW file Converter from Fuji?

 

OK -- definitely a demosaicing error. You're seeing an artifact of the CFA generated by a failure in the demosaicing algorithm. It's your processing software. From what you've written so far here's what I assume: You have an older copy of LR/Photoshop which does not support your camera. So you're using the Adobe DNG converter to generate a DNG file and then you're processing that DNG file with the older LR/Photoshop. Your older copy of LR/Photoshop is the point of failure.

 

For reference: processing using Fuji Raw Converter: clouds

 

Your options: You can keep doing what you're doing but you need to make a change in the Adobe DNG raw converter: Open DNG converter and under item #4 click the box Change Preferences. Click the dropbox Compatibility and select Custom. In the dialog that pops up check the box Linear. You're good to go. The DNG files will be larger but they'll work.

 

You can demosaic the RAF files wth other software. Fuji supplies a version of SilkyPix with the camera -- I used that for the above file. There are lots of other options from free to $$$.
