It’s true. This is a lens you will either love or hate! It just so happens to be very challenging to use and there has been controversy surrounding it since its release. When it was released, some users thought it was a very soft lens wide open and there were statements about it being so soft it appeared dreamy. That could not be further from the truth. This lens is pretty damn sharp wide open but the key is to get the focus right, and using a rangefinder makes it tough because this lens is usually calibrated for use at f/2.8 which means focusing with your rangefinder at 1.5 will not be accurate and will result in a soft “dreamy” look. It is called “Focus Shift”. Keep in mind that this only affects rangefinder cameras and using the rangefinder focusing patch. If you use this lens on a mirrorless system with live view you will not experience focus shift.
