I have been getting a lot of out-of-focus images, especially with the pancake 27mm f/2.8 lens.

My setting are:

  • AF-S: priority focus
  • AF-C: priority focus

Even in AF-S, I would say that I was getting in the 20% to 30% range of out of focus images. In AF-C, it would be even more. Basically the pancake 27mm was not usable in AF-C mode.

I know that it has to do with the lens because with the 50mm f/2, I get over 95% of the photos in focus. My skills haven’t improved or diminished by changing the lens.

Lately there have been a few discussions on out of focus images on dpreview.com and on fujix-forum.com.

Somebody mentioned that when the AF+MF is enabled, the camera sets itself to release priority even if the focus has been set focus priority.

The purpose of the AF+MF is:

  • To auto-focus in AF mode
  • Then adjust the focus manually on the lens while half-pressing the shutter button.

So, as far as the camera is concerned, it means that during and after the manual focusing, the AF registers as out-of-focus and the shutter switches to release priority.

When I switched from AF+MF on to AF+MF off, the number of images in focus, on my pancake 27mm f/2.8, has significantly improved.
