Just found out that the coating on the front element is damaged so my guess is that it'll be useless and flare like a wild thing .

Sean,
This was taken with my K-r and the 16-45 lens. f/8, 1/50th sec, ISO 200, 31mm focal length. Do you think this is any better than your camera/lens?
As Bill says perhaps your depth of field is a bit out? If your focus position is too close then you will not get full depth of field to infinity. Having said that, according to an app on my phone (lens Lab - suggested by someone on here and very useful), you would need to focus at or beyond a distance of 62cm at 16mm and f/22. At f/8 you would need to focus on a point 1.7m away or more for the infinity to be in focus.
Both your pictures seem to have good sharpness in the foreground. The rocks and pebbles seem fine. Are you worried about the far distance? They don't look too bad to me considering you have probably reduced the size of the photos for the web and you are pointing into the sun.
Thanks for your input,where was your focus point in this shot. Sean,
