Fuji X-Pro1 and Fuji XF 60mm f2.4 Macro

Today I added the Fuji XF 60mm f2.4 macro lens to the Fuji X-Pro1 XF 18mm f2 & XF 27mm f2.8 in my kit bag. My understanding is the XF 60mm f2.4 is a tad on the slow side when it comes to focusing, especially if compared to the rather more expensive XF 56mm f1.2 but is there away to gain an edge if using the XF 60mm for anything other than Macro work?
I would say yes and the trick is understand the problem and plan ahead. Think what you want to achieve with the camera lens combination. One thing I want to try with the lens is some candid portraits and grab shots without getting too close to a subject. The problem that needs to be overcome with the Fuji is a combination of slow focusing lens and the fact the the Contrast Detection AF (CDAF) employed by the X-Pro1 cant predict where the subject is going to be. I should probably also point out that unlike a DSLRs which use Phase Detection AF (PDAF) you don’t press the shutter halfway down to start the continuous AF. The correct way to use AFC on the X-Pro1 is to aim the camera at the subject with the cross hairs on the bit you want sharp and squeeze the shutter release in a single movement until the camera fires. I figured a small enough aperture with a reasonable DOF would help the focusing but as with all cameras that results in a drop in shutter speed and the possibility of losing the sharpness to camera shake or subject movement. My first instinct was to wind the ISO up but that has two drawbacks first is a drop in image quality second is a danger of over exposure in bright light. Fortunately the X-Pro1 has the option to program an Auto ISO. You get to tell the camera the minimum & maximum ISO you want to use and the minimum shutter speed it should be trying to achieve. What it doesn’t do is stop the camera working if the shutter speed drops too low it just tries to get up there if it can.
After a little fiddling about I settled on a minimum ISO of 800 a maximum of 6400 and a minimum shutter speed of 1/250. With the aperture set to f5.6 and AF set to continuous I roped in some help from my partner and our dog. As you can see from the images I had her throw a dog toy towards me so he would run towards camera chasing it. Each of the four images below is from a different throw of the toy. There were five throws in all and the results are pretty consistent for a slow focusing macro lens. The first throw I failed miserably and got only grass throws 2, 3, 4, 5 resulted in the images below. They have been cropped but still I think they are pretty impressive. You can find the camera settings for each shot in the captions. I have included the Thistle, shot in Macro, and the dog portrait to give a feel for what can expected if you forget to change the setting back to your ‘usual’ ones for situations that are more sedate.

I have to admit It was a glorious sunny day and the results may not be so good in poor lighting conditions but I feel I may just have an edge that maximises my chance of the subject being in focus while minimising the chance of camera shake with a set of camera settings that alow the X-Pro1 and Fuji XF 60mm f2.4 Macro lens to be used quickly and without too much though of anything other than composition.
