This post intends to, in a concise manner, list all known critical bugs as well as quirks – and then keep that list updated. The main reason for doing so is to help Fuji identify the community's reaction to the X100, as well as inform current and future X100 owners of the status of the camera's operability, since Fuji is not offering this transparency officially. The list was initially posted at DPReview but was too hard to maintain and keep updated there, hence moving it here.
Please reply to this post if a new bug has been confirmed with clear information on how to reproduce it – or the original forum thread discussing it.
List updated on Jul 31th, 2012, for X100 firmware version 1.30.
Fixed bugs will remain in this list with green highlighting.
Bugs – critical priority
AFL in MF focus method fails after 1.20 update – Original thread #1 (DPReview) and #2 (Fuji X-Forum) highlighting the issue– fixed in 1.21
Using the focal point in MF-mode with macro on one of the lower two lines or the right row will freeze the x100 after pressing AFL/AEL– fixed in 1.21
When close focusing in macro mode at f/2.0 and f/2.8 the camera will get achieve/show sharp focus just before the focus point box turns to green . When the camera focus box turns green, the camera goes out of focus and the out of focus image(diffused, not sharp) will be recorded – Original thread (Fuji X-Forum) highlighting the issue– fixed in 1.21
In Auto ISO, when you set Max ISO and Min shutter speed, the min shutter speed does not take effect until the camera is turned off, and then back on.– fixed in 1.21
Focus lock is lost when leaving viewfinder. This happens in AF-S or AF-C mode with AE/AF-lock mode set to S (Switch mode). Look in the OVF, half press, then lock focus (with AE-L button). Leave the VF for any reason, go back to VF and the green box reverts to white. If you lock focus in LCD instead, simply going to VF will have the camera loose the lock. In FW 1.13, it doesn't loose focus.– fixed in 1.30
- If you lock AF via the AFL/AEL button, it is impossible to define an AE correction factor via the EV correction wheel, even if the AFL/AEL button has been configured to exclusively lock AF – Poll link
- DOF preview via EVF doesn't work (AF-S/AF-C). Measure the distance to a target and lock the focus distance (in my case ~ 2m) in OVF mode. Then try to get a DoF preview via the EVF - the function cannot be called up if focus is locked. EVF is not being invoked.
- When the film simulation settings are on Astia and Velvia the "Sharpness" setting in the exif file are not listed when the push button toggle displays the picture exif, although sharpness is applied. The sharpness settings are displayed in the exif readout for Provia and B&W film simulations, but not for Velvia and Astia. I was told by Fuji that Astia and Velvia are film simulations, thus sharpness is not applicable. Should not the sharpness either be grayed out from the UI and not affect the image OR should it not simply work as-is but also register amount of sharpness in the exif? Original thread (Fuji X-Forum) highlighting the issue
- The aperture blade "dance" related shutter lag in MF mode. If this is needs to happen in the EVF, this should not have to happen when in OVF, thus removing the feature from the OVF should also rid the bug from this list ... Some users have been speculating that this happens in order to show the histogram and can be disabled only by the "Power saving" feature (which disables the histogram), however this doesn't seem accurate as the aperture dance still happens in OVF when power saving is on. In any case, this needs to be explained in the manual and/or release notes of future firmware updates – Original thread #1 (Fuji X-Forum), #2 (Fuji X-Forum) and #3 (Fuji X-Forum) highlighting the issue – Poll link
- When in Motion Panorama, there is a visual offset error of the values of the DR menu. If DR is set to "DR100" in Still Image mode, it will say "DR100" in Motion Panorama mode too. However, if entering the DR menu while in Motion Panorama mode, the selected value is "DR200". The value "Auto" is missing and if scrolling up to where it should be placed, the menus act up.
Quirks (besides DPReview's list of oddities)
- If you access ISO values via the Fn button, the list of available values does not contain Auto ISO. A simple solution would be to include an on/off toggle at the start or end of the ISO value list – Poll link
- Please elaborate in the next release notes on why the white DOF bar on the focus distance scale has changed between 1.13 and 1.20 (potential bug?) – Original forum #1 (Real Photographer Forum) thread highlighting the issue --- related: The DOF scale in Manual mode is highly non-linear. A better visual representation of this would be very usable for zone focusing. #1 (Fuji X-Forum) thread highlighting the issue.
- If you configure the AFL/AEL button to lock automatic exposure, then pressing the button will directly initiate an AE measurement and lock the result - no need to half-press the shutter button beforehand. If however the AFL/AEL button is configured to lock automatic focus, then you DO need to half-press the shutter button beforehand to make an AF measurement. NOT half-pressing the shutter button before will still make the AF frame go green, but the button will lock on to the previous AF measurement which might have measured a completely different target. Should not the AFL/AEL button work following the same operating sequence, regardless of whether it is configured to lock AE or AF? – Poll link
- Make Auto ISO minimum shutter speed configurable up to 1/500s. The current minimum of 1/125 sec is not fast enough for many situations, especially for street photography – Poll link
- The battery indicator is very unreliable. You basically need to carry a spare battery at all times. Thread highlighting the problem: #1 (Fuji X-Forum) and blog post with technical data: #2 (My Fuji X100, blog post)
- The Macro mode when set to Fn button should be consistent with how the ND filter works, a toogle on/off. And why not use the left button (macro) as toggle on/off as well – Poll link
- (The MF still does not work very well when the camera does not see anything –– This is an issue when you need to prefocus in a dark environment before aiming the camera at the well-lit subject, or simply when having the camera on a tripod when it's dark) –– MF ring responsiveness was improved greatly in 1.20/1.21, although by design it does not perform very well in low-light situations.
- In MF mode: Focus confirmation (visible green rectangle/graphic) and resizable and parallax corrected focusing area. These features should be the same as in AF-S mode, no? Currently, the rectangle represents the magnifier frame.
- When shooting in DR bracketing mode, all images are recorded at minimum ISO 800. It should be minimum ISO 400 for DR200 and minimum ISO 200 for DR100, which is what you would expect since this is how DR works otherwise.
- Controls are locked while images are being written to the card. On another (but similar) note, write speed seems slow for a "SanDisk 45MB/s Extreme Pro" card (takes approx 3 seconds to store RAF+JPG) - or is this the CPU crunching the data from the sensor that takes this long?
- In AF mode, the focus distance is reset after camera power-off. In MF mode, it is being remembered. It would be nice to keep the focus point at power-on for AF as well. A "miss the shot" feature...
- If the camera is turned on, then quickly turned off and back on - it stays off. A "miss the shot" feature...
- Exposure compensation is currently not available in manual shutter and manual aperture mode (M). This has been discussed frequently by users whether this should be enabled or not... Thread highlighting the issue: #1 (Fuji X-Forum).
- "Banding" appears in Motion Panorama mode at high shutter speeds. A simple solution could be to enable the ND filter to keep the current aperture and ISO, but it is not possible to enable the ND filter in Motion Panorama mode.
- The luminance histogram seems to be based off the LCD/EVF preview image. This makes it highly unreliable especially in M mode.
There are also countless posts regarding quirks in the "Recommended Updates/Improvements" section of this forum. My goal is to identify the ones that applies to most people and add them to this post's list of quirks.
And last but not least, thank you Fuji for taking this in!
