I have a Leica Q, the old one and really like it. The lens is incredible sharp with lots of contrast. What other lenses give me this feel? I can't afford Leica lenses because they are so damn expensive. How are the Voigtländer Apo lenses? Looking at the 50mm f2 APO-Lanthar for example. In reviews it is described as very sharp even at f2. Or does it also depend on the sensor?
