I can’t say for sure if will remove it but I’d try a dedicated sensor cleaning kit, or if you have a local shop that does repairs they might offer cleaning services too. 

It’s not the lens itself, it’s the perspective that changes. A 50mm forces you to move back to get the same field of view so your perspective changes. 

You have changed from a 35mm lens to a 50mm which forces you to change your perspective. Try a 35mm on the XT-4 and your shits should look like they used to. 

“Best” is very subjective, and I’m always wary about answering questions phrased that way; that being said *I* use DxO pure raw3 in conjunction with Lightroom Classic.  With that, I share a linked collection that allows me to access my Lightroom classic catalog with Lightroom Cloud, giving me viewing and editing capability across the internet and all my mobile devices.  

Maybe this is better....

I was reviewing some more of my shots from my recent trip, and I noticed something in one shot that at first I thought was trouble, but turned out to be shocking.  Here are two images....
 
Here's the first - I purposely used the top of the spire to shield the sun, to allow it to halo the top as part of the composition....

 
 
 
 
 
 
 
 
 
 
 
 
 
 
When I zoomed in to see about cropping it some, I noticed spots, and thought, "wow the lens or sensor got REALLY dirty, and that's a shame.  Wasted shot."  I looked at the other images immediately after and before it, and there were no spots, so I was naturally confused.
 
Zoomed in...

That's when I realized, those aren't dust spots or bad pixels, those are... STARS.  The dynamic range was wide enough that it could pick up the faint starlight that was mixing in with the sunlight, stars that are always in the sky, but normally invisible due to the intensity of the sun.  I am impressed with the ability of the sensor in the X-T5 to resolve these details.
post edit - the compression when posting the image ruins the details, sadly.  I may post another one REALLY zoomed in to show it better....

Since there is no topic for landscapes in b&w, I thought let's create one...

Hello all, I’m Gordo from Australia and haven’t even received my first fujifilm camera yet (it’s on its way). I have used a variety of cameras over the years though but look forward to my Fuji journey. 
Cheers
