I am really struggling with the metering on the Fuji X100 - to the point where I wonder if my model might be broken. It has often over exposed frames, but seems to be doing so more than before now, to the point where it is happening on most frames. The extent that they over exposed by is extreme as well with the camera 'whighting' out the frame completely more often than not. The only good thing is that shooting manually on the X100 is really easy, I normally shoot in Aperture priority so I just have to reach up to the dial at the top and dial in a shooting speed. I did have the camera set up for Auto ISO, I have now taken this off, (couldn't remember how to do it when hanging precariously off the river bank the other day though). Any ideas what might be wrong? Is it me, the camera or is the metering really that bad with this model? Example below. Attachment: untitled-0772.jpg (Downloaded 60 times) |

Theres something not quite right there Rich. I think Eric and Jonathan will be the best ones for this as they both have experience with the X100 |

Nothing as bad as yours though. However I found mine to be operator error on two counts... 1)I failing to realise I had the f2 settting on the aperture ring ....and selecting ISO and/or shutter speed outside of the range for the ambient lighting 2) adding to this the exp comp dial wrongly set. Both of these were lack of attention because the X100 is prone to having its knobs moved getting it out of the case!! But I am guessing you have discounted these basic possibilities in your checks and the metering method is correct. So it would suggest a camera problem, like the iris is sticking ? Have you looked on the X100 forum? I am not on my desktop (where the link is) so maybe JK can provide the link if you don't know that forum? |

That looks suspiciously like an out of range exposure i.e. the ISO is too high and aperture too large/wide open for the shutter speed to accomodate. I have FujiX forums open. http://www.fujix-forum.com/index.php?/forum/3-welcome-to-the-fuji-x-forums/ You might have the SAB sticky apperture blade problem that comes up but I would expect that you would be persistently seeing this with your images. But you do mention that it is happening more frequently so I worry about the SAB. The EV dial issue then may be a possibility. I went through a spate of these over exposed images but I solved it with an O ring around the EV dial. I'll try find the link in a minute but it is a cheap and effective solution. http://www.fujix-forum.com/index.php?/topic/941-o-ring-stiffens-exposure-compensation-dial/page__p__17042#entry17042 |

I have made some poor shots with the EV dial - but on this tree every time I metered on it the whole shot blew out. The Exif shows exposure comp at zero, ISO at 200 and aperture at f11, I had the ISO on auto at this point and camera in Aperture priority at f11. By metering 90 degrees to the left I was able to get a more sensible exposure setting. I had read about the sticking aperture blades, but if I shoot manually it seems to be fine? On one X100 forum post I read however someone had sent their camera back to Fuji to be told this was the issue (apparently common with this camera). He was told it was being fixed and was awaiting return, but also made the comment he had no problem when exposing manually. |

Hmmm. Not experienced that thankfully. What Firmware version are you using ? I have seen some similar problems reported on v.1.21 I'm busy learning about the XP1 at present and testing out stuff. It is similar but different to the X100 but I am enjoying the fact that I have a 60mm macro lens which is wonderfully sharp. The 35mm f1.4 is as sharp a lens as I have ever used. In fact both are wonderfully sharp. |

Yes, same problem in Landscape. |

richw wrote: Eric wrote: Rich What is the ISO of the over exposed image? The reason I ask is I just got an overexposed image using auto ISO because the default ISO level set was higher than the required ISO. Let me say that another way..... The camera is set with auto ISO ON (max of 3200ISO and slow shutter of 1/20th) I flicked the lens to f2 and shutter speed to 1/250th. It is unusually, a sunny day outside. The camera ISO had been left on 2000 from previous use...far too high for the settings and conditions today, so it created an overexposed image like yours. What surprised me is that the auto ISO didnt kick in and reduce the ISO from the too high camera setting. On my camera .....Auto ISO adjusts UP when I have too low a default ISO setting for the available light and settings...but doesnt bother to adjust DOWN if I have it already set at an ISO above what auto ISO thinks is ok !!!!! |

Sounds like a bug in the firmware. |

Robert wrote: Sounds like a bug in the firmware.I say so but Fuji say that is as intended and that you should put your ISO to a low value and allow the camera to adjust ISO upwards to obtain a match with your minimum shutter speed or higher and f stop chosen. I think it should be like on the Canon and Nikon where it adjusts ISO to get the correct exposure. That is what users expect. In fairness to them they have set other parameters such as minimum shutter speed and say this is intended for low light level shooting not for sunny situations. |

Eric, Rich's photo shows EXIF with ISO 1250, f16 and 1/60th sec shutter speed. This equivalent to EV+10 which is not so bright, probably a UK bright overcast day. I'm worried as this implies a SAB problem to me. |

jk wrote:Eric, Maths isn't my strong point but for a sunny UK day (100asa f16, 1/125) Richs settings would be 4 stops over exposed....wouldnt they? |

jk

Yes four stops is right. I also notice that the EXIF I am seeing is not the same as Rich is quoting. He says f11, I see f16. Wish I was in Oz as I could test with him. |

Rich- If your firmware update doesn't help, fill out a tech support request on the fuji Web site and you will hear from them within a day and will give you a contact to call for help. If you have to send it in to them, they pretty much promise to turn the camera around in 24 hours from when they receive it and send it back overnight delivery. I think you will scratch your head and ask why every company's support isn't this good  Tom |

I no longer think it's the metering that's the problem on this. Shooting manually getting some very weird results. The below was taken on a bright but overcast day (taken just to test exposure). At f16 and ISO200, using sunny 16 I set the exposure time to 1/250 (closest thing to 1/200 available). Badly over exposed result seems to me that something is wrong with shutter rather than the meter. Exif data is correct other than the date which seems to have got out of kilter somehow.

I got an OK exposure at f8.0 by experimenting. The below was shot at 1/2000 at f8, ISO200. Once again using Sunny16 as a guide I figured this should have been roughly 1/800? Attachment: untitled-0220.jpg (Downloaded 21 times) |

And as annoying as getting the exposure right is it's still great to have a camera that will slip into a pocket and take out with you when I would never take a DSLR. I can still play till I get it about right. Here's one of Jac and some friends.  |

Rich is there no way you can have the camera checked out by Fuji. In fact many camera repairers have a shutter speed test mechine. |
|||||||||

Rich- One thing you didn't mention... Were you using OVF or EVF? The metering and focusing CAN be more exact in cases like this by using EVF. You can also set the size of the focus and metering square in the EVF mode to quite a small spot. Try that on the same scene and you might have the answer. Like others have stated, when I've had this problem, it has been a problem between my two ears. Most common, the ev dial, next most, aperture too wide or all the way open unintentionally. I pretty much always use the auto ISO and the only times I haven't liked that is in very low light where I want faster than my set minimum shutter speed, so I just go manual on that shot. Let us know if you work it out. I had to call Fuji support in USA one time and found they were really really really nice and helpful. Tom |

There is also one instance that this over exposure can be induced. If you switch the camera on and almost instantly take a shot then this will happen. You need to power on then do a 1/2 shutter press then release and then do another 1/2 shutter press, before triggering. |
|||||||||
Eric

Rich Have you stopped the aperture right down to minimum and set the lowest Iso ....in dark conditions ....to get the shutter speed a lot slower? The reason why I ask is, I recently broke a bit of a lens mount and I now periodically get way overexposed images. I noticed that the incidence of overexposed images was greater when using fast shutter speeds....or should I say short exposure lighting sitauations. I reasoned that the damaged mechanism was impeding the action and erroneously extending the exposure. Of course this error had greater significance with short exposure situations. I managed to get by, fixing the Iso lower than necessary and using smaller than usual apertures to extend the exposure time. It's off to Nikon now for repair. But I do wonder if something is dragging its feet in the Fuji and needs servicing? |
