Re: Use this depth of field calculator for comparisons

On the question of DoF, an online calculator for the K7 indicates that 50 f/1.2 yields a total DoF of .57 feet at 10 feet, compared to the 85 f/1.4 yielding .23 feet at 10 feet. Even if you are compensating for framing (which you might or not want to do based on the situation), at 6.5 feet for the 50mm f/1.2 - you are still at .24 feet for DoF; but this isn't really apples to apples because of shift in perspective created by framing closer.
