Originally posted by ncallender I think I need to do a full calibration of all my most used lenses and give it one more shot.
If the images look sharp on your computer monitor without any post-processing, then your camera is capturing sharp images in its current setup. (It may be that your lenses need calibrating, but this is often a last resort after all the other options have been addressed.) With the situation as you describe it, if I'm understanding correctly, I'm more inclined to suspect a problem with the LCD. These can be susceptible to heat (and cold?) damage.
I have adjusted fine sharpening in the Custom Images profiles (Bright, Natural, etc.) on my KP based on recommendations here on PF. But, before doing so, the images looked fine on the LCD.
