I tested the lens focus against my 77mm. It seems that the front focus on my microwave was due to my camera having front focus in indoor light. (K-R is known for indoor FF issues it seems.)
Below you can see both my lens have FF indoors and are good outdoors. This solves my issue ... thanks!!
Photo #1 - 40MM DA outdoor - NO FF (very slight)
Photo #2 - 40MM DA indoor - FF Issue
Photo #3 - 77MM FA indoor - FF Issue
Photo #4 - 77MM FA outdoor - NO FF
(Not sure why the color balance is off so much indoors ... i did not check the setting at the time.)
