I've been shooting since 2001
Currently I own following autofocus cameras: an original X100, the X100V, XT1, The original Leica Q, and Sony A7III
The X100V is by a landslide the most unpredictable and unreliably out of the bunch when it comes to autofocus.
It get's easily confused when subjects are between 5-20 meters away.
The autofocus miss and end up on a distance between 2-3 meters, when the real object is actually more then 7 meters away. This again resulting in a slightly soft subject, while the foreground is nice and sharp.
I shoot most street, so i don't need monster fast AF. As a matter of fact, the original x100 has ben perfectly fine, and I never ended up with an image out of focus with that.
Same goes for both the XT1 or the XT2.
This is how i use the camera, and it's pretty basic.
I use singel autofocus point. The next smallest box.
I use an F-stop at around F4 to F8 99% of the time, where F5,6 is my sweat spot. I shoot mostly in good sunny conditions where the ISO never goes above the 400 mark.
I normally focus at an object at the distance my subject will be, and wait until subject walk into the frame then shoot the image. Or i do a focus recompose.
This works 100% of the time whit all other cameras then the x100v.
I notice the same behaviour on an X-T3, but thought the camera was faulty and end up trading it in.
And you should be able to easily recreate it.
1. Activate the focus distance scale on your X100V/xT3/XT4
2. Set F stop to F 5.6 or higher (make sure its good light outside)
2. Make sure u got a target at say 5 meters and one at 10+ meters (both with excellent contrast )
3. Now, focus between them and shoot image after focus is acquired. Watch where the focus point lands on the distance scale from time to time.
you will se it jumps around and now and then completely misses, like set the focus at 3 meters and you subject is more then 20 meters away.
Watch the image and see how many it will fall short on. So is there any one out there that recognize this and have a fix for it?
