The X-Pro 1 uses contrast detection autofocus (CDAF) compared to phase detection autofocus that is usually found in DSLR cameras. As I have shown in an earlyer post, I like to photograph at minimum aperture to create a shallow depth of field. And in those situations perfect AF lock is essential for good results. The advantage of contrast detection is, that it is very accurate when it locks onto the target. On my phase detection DSLR camera I have gotten used to pushing the shutter half way for 2-3 times before I trust that the AF locked correctly onto the subject.
So is the X-Pro 1 useless for moving subjects? Not at all! You just have to approach things differently to get good results! Here are my tips to get the best results from the X-Pro 1…..

Try laying the AF point across an area where the only contrast is a horizontal dividing line between two objects – in my case the top of a TV or picture frame vs the wall. The AF will struggle to focus, and depending on the circumstances, fail to lock more often than not. However, tilt the camera by 30-45 degress, or even 90 degrees, and it will lock – every time. Note that 90 degrees – horizontal lines don’t seem to cause a problem in portrait mode, only lines parallel to the long edge of the frame.

Personally, coming from a Canon EOS 40D, 60D and 7D I think the autofocus on the X-Pro1 is quick for what type of camera it actually is. It seems like the X-Pro1 is receiving a lot of criticism regarding the autofocus speed, but I’m thinking that this is because of too high expectations from people which are moving away from DSLR’s (Phase Detection AF) to a mirrorless and more compact camera with contrast based autofocus. Is it really that sluggish? I personally don’t think so.
