Nice shot, though a shorter exposure at a wider aperture would have probably yielded better sharpness!

Agree with you totalty on the exposure however I have been trained to go for depth of field in my job. I need to learn more of a balance between the two. My main focus of photo's will be used in court so they want everything in focus. I'm close to retirement and need to unlearn some of my practices. I'm wanting to photograph old courthouse in North Texas at night so I will be wanting better sharpness. Thanks for the advice.

In that case I'd suggest limiting the aperture to F16. There's a huge drop in sharpness going from 16 to 22.

Thanks will try it as night photos are a challenge for Crime Scene People. Paint with light ha limitations so time is our friend at night.

Diffraction is indeed a problem at these F-stops.
The best lenses like primes often top at f/4 and that goes down to f/8 but most of the time f/16 is more then acceptable.

To maximize the range of depth you can try to do hyper focal focusing.

Tried some more photos tonight.
1) F4 @3 sec
2) F4.5@ 6 sec
both at ISO400 and 50 mm focal lenght
Light was so low auto focus would not work set at infinty.
I would be happy with these as distant shots of a crime scene. if markers or object were spread out it would be different.
