X100F: Issue with OVF manual focus distance

8 posts in this topic

I just got an X100F, and set it up for the way I shoot street photographs: auto ISO; shutter 1/250s; aperture f/8; and manual focus distance set to hyperfocal distance - about 11feet (approx 3.4m).

Using the OVF, the focus distance marker nudges upwards every time I press the shutter release (or even half press it), so that in about five presses it's nearly up to 15feet (about 4.5m)

Remember, this is on MANUAL focus - so pressing the shutter release should not change the focus distance at all.

This only happens with the OVF: the focus distance indicator on the EVF and LCD stays in the chosen position.

Has anyone else seen this behaviour? (Grateful for any feedback about whether this is a firmware fault - I've upgraded to latest firmware.)

Does the focus distance actually change? I mean, if you continue to take photos do they become progressively more out of focus?

I haven't tested it thoroughly, but I don't think the plane of focus actually moves.

I suspect it's just the indicator bar on the focus distance scale that's shifting - which is why I think it might be a firmware bug. But if others are not seeing this issue with the same settings as I describe, the firmware theory may not be right, and the problem may be with this particular camera.

this was a known issue with X system ILCs with one particular firmware update that introduced a bug, that was later updated to fix. In MF mode, the focus distance slowly moved every time the shutter was half pressed (I seem to remember it moved to minimum).  Do some proper testing, as if you can recreate it then it needs to be reported to Fuji again.

I understand from Fuji Tech Support that Fuji knows about the issue and is working on a firmware update; but there's no release date yet. (Firmware 1.01 didn't fix it. If anything, I suspect it made the problem worse.)

sorry to hear that. I hope the next firmware version doesn't take too long to be available. Speaking plainly, they really need to get on top of these issues, as they seem to keep having these types of problems, and although some may regard them as "minor" it shows a poor quality control process for software.

hope you get a resolution quickly. I assume the work around is to constantly adjust the focus distance manually before every shot?

The focal plane isn't actually changing, so you could just keep shooting. The trouble in practice is that even wtih my other Fujis (X-Pro1s / X100s) when shooting manual focus at the hyperfocal distance, it's easy to accidentally knock the focus ring - but with the X100F playing up, you can't be sure whether you've done that, or the camera has changed the marker position while you weren't looking! ;)
