One thing I don’t see with pentax is fast glass, the fastest I could find in production is F2.8 so this would be like F2.2 on FF

My question, can a FF 1.4 lens stopped down to F2.2 be as sharp as a 645crop F2.8 shot wide open?

would this not give an edge to FF ?

An f/1.4 lens does not have to be shaper at f/2.2 than a true f/2.2 lens, just the opposite.
