Hey Royce, I'm not really seeing a soft focus? That silo looks pretty sharp to me and the first one looks good too. The 3rd one looks like the softness is coming from the water moving?
All 3 are outstanding to say the least!
I've never really shot wide scenics and usually try setting a subject in the foreground and what I do is light the subject with a spotlight (Q-Beam or High Powered Flashlight) and make sure it's in focus with the light on it. Then I turn off my autofocus and just shoot away bracketing my shots to get the best results
This was last weekend camping in Okeechobee Florida before the big moon came up and ruined the sky
This one was in Michigan's Upper Peninsula (Bond Falls State Park) a few years ago, but you can see in both I have a foreground subject to pre-focus on, so I'm not sure if I have an answer for you.
Unless you got there real early, set the camera on a tripod, focused and left it there till it got dark later in the night? Although by then the adult beverages might get in the way
