Curious if I have A bad lens, viewfinder never demonstrates a clean, crisp image. Only this lens is/has been like this.

Always a bit blurry. LCD Display is crisp…

Thoughts/Feedback is appreciated. This is my first Macro.

Did you accidentally move the Dioptric Adjustment Knob that's right next to the viewfinder (to the right) while attaching the lens?

Was thinking the same thing. Try checking diopter adjustment by the viewfinder to see if this could be the cause.
