white pixels appearing on images

[MrPolite]

Hello,

I've been using my XT-1 and only recently i noticed that there are a few white pixels appearing on images. I tried blowing on the sensor with a tool and took a picture with the lens cap closed, but I still see these pixels. 

 

Not too familiar with sensor issues, but since they appear even with no light (cap closed), are they "bad pixels"? I didn't think this would be something that's common. Any suggestions?

Here's a crop of the area where this happens

You appear to have some defective pixels ( might be dead or not), this is generally speaking, reason to have the sensor fixed, changed or in some cases the camera replaced.

ah surprised that this happens after a whole year... hopefully the warranty is still valid. Any pointers on where to send it to and who to contact? They seem slightly obscure about their service 

[milandro]

as usual the first and foremost place to get in touch with is the shop where you bought it.

 

In lieu of this the warranty applies in any country at the distributor, this is true even if you bought somewhere else.

 

Everything sold in the EU carries a statutory minimum guarantee of 14 months.

 

You might have not noticed this before but it was probably there from the start. Most people never notice this because they never test it.

Thanks milandro... nah I've looked closely at many other images and it only appeared the last few weeks

 

I've bought this in north america from B&H, .. hasn't fully been a year yet. So you think I'm better off contacting B&H first or just send it to Fuji?

[milandro]

No in case on B&H they don’t have a guarantee to honor. Get in touch with Fuji in your country.

Just in case they might say they are not responsible.......they are, for a minimum of 1 year

 

Should they be resistant and uncooperative get in tough with Tokio head office.

Thanks again! 

Someone from Fuji responded saying I should send it to their Edison center for repairs... crossing my fingers that it won't take forever

They called hot pixels, occurring during long exposures or high iso values. Those pixels are more sensitive by light than the others. I had this problem on my X-T1 within two months after purchasing. Went back to the store and they send the camera to Fuji service where they remapped the sensor and I have no problem up to now! 

[milandro]

Nice to hear that Fuji came up trumps 

 

B&H doesn’t......

All items sold by B&H are warranted solely by the manufacturer/distributor, except "direct import" a/k/a IMP items. All items needing repair (other than IMP) should be sent to the manufacturer/distributor directly for service. B&H is not liable if the manufacturer/distributor fails to perform warranty service.

This effect is a very common one and is caused by dead or damaged pixels.

Pixels may be "stuck on" and a single pixel producing a bright one colour dot or a small group of pixels

 

In images they are often termed "hot pixels. Most sensors have some. They are a common consequence of aging. Some sensors will have them from new, some won't.

 

LCD screens also have them. Software is available to map them and to adjust the image to greatly remove their effect. As a simplistic example, if you had a single "hot pixel" if you averaged the light values in the adjacent pixels and replaced the "stuck" value wit the average value it would be exceeding unlikely to be noticed in the very large majority of images. The algorithms used for correcting them are liable to be more complex than this but this explains the concept well enough.

 

Some cameras have a hot pixel correction function - a long exposure shot is made in 'total darkness' (eg - with lens cap on) and the camera then adjusts for anything it finds in the dark frame.

 

Hot pixels will usually be most obvious in areas where they stand out against the background, and in longer exposure images.

 

"Stuck" pixels are most obvious if they are stuck on - but pixels that are always off will also be encountered. Here's an image showing an always off greem pixel.

Same here with my one year old X-T1. All images from the last two days show one white pixel (reproducable with lens cap on, normal exposure 1/30, ISO 200). Unfortunately I bought it used and while have the original receipt from Amazon.de, I'm not sure, Fujifilm support will handle it as waranty case.

Funny this came up recently. I just noticed the same thing with my X-T1. Between that and the warped accessory port door, I'm finally sending it in for warranty work. The camera wasn't abused but it is scuffed a bit and some of the rubber grip is loosening a bit - I hope they don't try and say it's not covered under warranty anymore. Fingers crossed.

My accessory port door was warped too, it seems like bad design. They replaced it for me as a part of warranty.

Between that and the hot pixels, I finally sucked it up and shipped my camera out to them today. I was having trouble with their customer service for the last little while, and just realized they have a separate customer service department for the "pro" X series cameras. I found that out this morning and everything has been so much smoother - the replies were so much faster and the guy was helpful and straight forward. I got more accomplished in two or three emails this morning than I had in a dozen or so emails over the last couple months. 

 

I'm not sure if I listed too much, but I made note of the pixels, the warped door, and the rubber grip starting to come loose. I'm pretty sure I have an early copy of the camera, so I'm hoping they'll just replace it. We'll see how it goes.

Ah yea they treat the pro line differently. I need to contact them again for sensor issues and they're not responding via email! Could you direct message me the contact info you found for the pro center?

For sure, are you in Canada?

Ah no in US! sorry thought you are here as well

The Problem has been solved by Fujifilm Germany on waranty. It took two weeks including shipment, about five working days for testing and repair, including firmware update to 4.10. So for me everything worked very well, no problem buying an X-Pro 2 or X-T2 next year.

[Phil]

I'm happy to report good news, too.

 

I got my camera back today. I shipped it out Friday Oct 31 and it arrived at the repair centre Monday Nov 2, so it was pretty much exactly one week's time. Something I found interesting is that Fuji's arranged pickup was through Purolator, but they shipped it back to me via Canada Post. 

 

So far it seems like this was a great experience. They didn't explicitly mention the hot pixels or sensors in the repair log, but they had listed it in the description of the camera upon arrival, so I'm guessing that means they addressed it. They gave it a "Pro Service Level 2" (whatever that is ), replaced the accessory port door, and to my surprise, replaced all the grip. If it weren't for a couple scuffs on the metal, I would have thought they'd given me an entirely new camera. I didn't realize how faded the rubber had gotten on mine.

 

I was nervous, but I shot a couple frames with the lens cap on and couldn't find any hot pixels. The accessory port door doesn't seem any different, but it's flat and sits flush, so hopefully it doesn't warp on me again. It feels great to have a camera again. That was a long week.

 

edit: Forgot to mention Canon. I sent my 70D out twice for autofocus issues (I couldn't get the micro adjustment to calibrate properly), had to wait two weeks each time, only have Canon send the camera back to me stating that it appeared to be in working order. That's mainly why I was so nervous about sending this one off to Fuji, but thankfully it was an entirely different experience.
