I just noticed a little red dot in one of my photos from about two weeks ago. The strange thing is, I tried every test I could find about the issue, and a hot pixel shows up with both my Olympus 14-42mm and my 40-150mm, but the strange thing is, I cannot find a hot pixel if I take a shot with my Sigma 50mm.

This is the photo that I discovered the problem in. The second shot is where you can actually view the detailed area. The hot pixel is in the subjects shoulder area.

Has anyone else had this problem so soon with a camera? I got this camera brand new in June 2009 and it is now only August 2011. Any information that will help me out is much appreciated! Thank you.

Olympus cameras have a function built in called "pixel mapping". Read your manual for the camera or search for "Olympus pixel mapping".

I had a new Canon P&S with a hot pixel. You have to send these to Canon to be corrected (they just map them out), but they simply ignored my emails. I probably should have simply returned it to the shop as faulty.

All cameras have defective pixels. These are normally all found during production and are simply mapped out (my Canon P&S being an example where this process didn't work entirely). The manufacturer programs a list of pixel faults into the camera and when a photograph is produced they interpolate the faulty pixels from surrounding areas. The problem is that over time more pixels will commonly go bad. If you have an Olympus then you just run pixel mapping if you find any -- problem solved.
 
Pixel mapping is built right in to the camera.. Simply run it and be done with it.

Its not unusual for a hot pixel to show up at any time or any age of the camera.. Thats why you have pixel mapping in the menu.. So you dont have to send it out to be fixed.

I did just that and I think it worked! As far as I can see that is. Now this is a random question, do you know anything about pixel mapping as far as Nikons go? My significant other has a D40 and it was previously used before she got it a year or so ago. Is there a pixel mapping mode for Nikon?

The makers or photoediting software just hate this Oly feature :)

No, Nikon has nothing. On the other hand...

Only my Olympus cameras ever needed that feature. The D300s which is two years old now has no issues, just like the Canon G10, which is about three years old now.

BTW, why do you ask? Your wife's D40 got the problem? How old is the camera? Maybe it is time for a “check-up and clean” anyway... ;)
 
Is Pixel mapping in user controls unique to Olympus?

I picked up about six in a short period and 30 seconds mapping plus a cleaning cycle with a blower solved it.

Think about things like this and in body stabilistaion, remote flash control etc I loved OM and hope I will still love E in four years time!

Yet my brand new Canon P&S had a hot pixel.

It is a fairly random process, so you may be fortunate and never get one (or at least not notice it), or you may get a rash of pixel failures.

One of my E-1s seemed to lose track of the already mapped pixels, or suddenly sprouted a few dozen -- I can't tell which, but from zero to a great many in an instant seems unlikely.

(Maybe a really big photon hit the sensor and broke into lots of little bits and took out the poor pixels? :))

He asked because his two year old E-410 developed one hot pixel, and he was not aware that this function is user-operable with Olympus.

I really don't understand why this feature isn't available on all brands. Does it do some harm?

Apparently it does.... to their service profits and upgrade lifecylce...;-)

Maybe yes...

...as the need for such function seems to be Oly specific as well.

If you need remote flash control... get Nikon. It has the best flash system available. If you like old Nkon lenses than Nikon in many ways is better than Oly because you have full control of the aperture, can focus wide open, set the desired aperture and the camera stops down for you. No adapters needed and you even get focus confirmation.

Maybe Pentax has pixel mapping as well, I don't know, but if you like Pentax lenses the Pentax system is also better than Oly since you don't even need an adapter to use them on their DSLRs and you even get focus confirmation without those stupid adapters. I don’t know if their IBIS is working with the old K lenses.

Anyway, I don’t think Oly is alone with IBIS, Pentax and Sony has it as well if I am not wrong.

If you need pixel mapping than maybe Olympus is the only option but only maybe. I know Nikon does not have it.

I would be the last to say it never happens with any other brand than Oly. I know even some Nikon issues, not only old consumer models, but also new upper level ones.
It is a fairly random process, so you may be fortunate and never get one (or at least not notice it), or you may get a rash of pixel failures.
I'd agree about the "random" part concerning my Nikon and canon experience but the number of Oly cameras went through my hands is higher and it ranges from P&S up to E-3. Each one needed pixel mapping more than once and on a quite regular (less than yearly) basis.

Anyway, it has been a while ago I last checked, maybe I'll check my cameras today.
One of my E-1s seemed to lose track of the already mapped pixels, or suddenly sprouted a few dozen -- I can't tell which, but from zero to a great many in an instant seems unlikely.
The pixel mapping is done in software and as far as I know reset to factory default resets even the map.

He asked because his two year old E-410 developed one hot pixel, and he was not aware that this function is user-operable with Olympus.
Right. Then again, perhaps he did not look before, and I am not sure there is only one single pixel, there may be more. Anyway, in that image I'd worry more about the exposure than the hot pixel... Remember that hot (or dead) pixels are mostly visible in dark areas and most of the time only at very high magnification. Most people look at their images in quite small sizes and in that case it may not be that obvious.
I really don't understand why this feature isn't available on all brands. Does it do some harm?
Of course it does no harm. I do agree, it should be in every camera. I don't know why it is not included, but in any case no big deal, it is not a show stopper. I think there are more important features than pixel mapping.
 
...as the need for such function seems to be Oly specific as well.
A google search would suggest you are very wrong.
Think about things like this and in body stabilistaion, remote flash control etc I loved OM and hope I will still love E in four years time!

I think there are many happy remote flash users from other brands, including Olympus.

Another Nikon advert? Again, there are many happy users of old lenses on other systams, including Olympus.

I don’t know if their IBIS is working with the old K lenses.
Now Pentax is better than Olympus. Poor 4/3 fools taking photos with their "stupid adapters". What relevance has this to the OP?

Pixel mapping is a wonderful in-camera tool. If it happens to me, I can Pixel map in a couple of minutes, as opposed to sending it in for a service.

Why did you turn this thread into an Olympus bashing opportunity? The OP was asking about a stuck pixel, not lenses, adapters etc., and certainly not Pentax!

Am I? I am just sharing my experience. That's all. How can that be wrong? All 5 Oly cameras I had needed it. Neither the Canon nor the Nikon I have now has ever needed it, but I would never claim that they will not need it ever.

Yes well, I have not said otherwise, have I? What I meant is that the Oly remote flash is not very special, is it?

Another Nikon advert? Again, there are many happy users of old lenses on other systams, including Olympus.
Advert or not, interpret anyway you like. The post I replied to make it sound like Oly OM support was unique. The Oly implementation of legacy lens support is rather poor compared to others, Nikon included. I don't say Nikon is best in this respect, that's your own interpretation, I just say the Nikon implementation is better than the Oly OM support.
Maybe Pentax has pixel mapping as well, I don't know, but if you like Pentax lenses the Pentax system is also better than Oly since you don't even need an adapter to use them on their DSLRs and you even get focus confirmation without those stupid adapters. I don’t know if their IBIS is working with the old K lenses.
Now Pentax is better than Olympus.
I believe the Pentax implementation is the same as the Nikon but since Pentax has IBIS it offers even that. All that without adapters. Take this as a "Pentax ad", I regard that to be the best solution for those who like the IBIS.
Poor 4/3 fools taking photos with their "stupid adapters". What relevance has this to the OP?
OK, maybe I am missing something. He says "I loved OM" but might not mean he has any OM lenses at all. If that's the case than I agree, it is irrelevant that Nikon, Pentax and Sony has better support for old lenses than Olympus has for the OM. Never the less, it is a fact that you need that "stupid adapter" if you want to use OM lenses on any Oly camera, but yes, that may be irrelevant. But leaving your emotions out for a moment...

...isn't it better to use a lens without adapters than with adapters?
...isn't it better to spend the money on other things than "stupid adapters"?
...isn't it better to use a lens with aperture control than without?
...isn't it better to have focus confirmation than not to have?
...isn't it better to have IBIS with any old lens than not to have it?

...just think for a moment without emotions.

There is nothing in what I said which indicates that FT users can not happily use their OM lenses. If you know anything about history you should know that I was a huge fan of legacy lenses and other OM gear long before you entered the scene, but fact is a fact, and there is a huge room for improvement and we all know by now that there will be no improvement in that department.
Anyway, I don’t think Oly is alone with IBIS, Pentax and Sony has it as well if I am not wrong.

Pixel mapping is a wonderful in-camera tool. If it happens to me, I can Pixel map in a couple of minutes, as opposed to sending it in for a service.
Right, and I wish every camera would have it. But is it so important that I would base a decision on it? Definitely not.

You see, it is called "bashing" only by those who don't want to open their eyes. The in body stabilization, remote flash control and OM was mentioned in this very post you reply to. There is a lot of falsified misinformation going on around here and many people believe that Olympus is unique in that respect. I always welcomed information as opposed to misinformation . It was on this very forum (1022) I learned that Pentax and Nikon has better legacy support than Oly, and that Oly is not at all specific in it, quite the opposite, it is the system which has the least support, or is just pretty ordinary, nothing special. However, that's just technical information, not bashing, at least not according to my vocabulary.

Too much emotions in your post... ;) but that's OK, after all this time on this forum, I am not surprised.
 
Sorry - message limits...

Yes you are. You made a blanket statement without qualifying. A reader in these forums may form the opinion that stuck pixels are an Olympus only problem from your comment. I clarified for balance.

"If you need remote flash get Nikon. It has the best flash system available." is a sweeping statement. I commented purely to balance your personal sweeping statement. There are many, many third party remote trigger options.
Advert or not, interpret anyway you like. The post I replied to make it sound like Oly OM support was unique. The Oly implementation of legacy lens support is rather poor compared to others, Nikon included. I don't say Nikon is best in this respect, that's your own interpretation, I just say the Nikon implementation is better than the Oly OM support.
The OP didn't mention OM lenses, and the thread you replied to was commenting htat he liked "OM" cameras before, and now he likes "E" system cameras. Nothing at all to do with legacy lenses, but you saw an opportunity to plug Nikon. Why do you feel the need to do this?
I believe the Pentax implementation is the same as the Nikon but since Pentax has IBIS it offers even that. All that without adapters. Take this as a "Pentax ad", I regard that to be the best solution for those who like the IBIS.
But, why bring Pentax to the thread at all? It seems you want to dissuade anyone from buying Olympus cameras. There was absolutely no need to mention anything about Olympus. I just can't fathom why you would go on a tangent like this on a "stuck pixel" thread?
Poor 4/3 fools taking photos with their "stupid adapters". What relevance has this to the OP?
OK, maybe I am missing something. He says "I loved OM" but might not mean he has any OM lenses at all. If that's the case than I agree, it is irrelevant
Then why post?
that Nikon, Pentax and Sony has better support for old lenses than Olympus has for the OM.

Again, no emotion here. Just facts.
...isn't it better to use a lens without adapters than with adapters?
...isn't it better to have IBIS with any old lens than not to have it?
Red herring fallacy. Nobody was talking about lenses in this thread before you.
...just think for a moment without emotions.
I am. Are you? The reason I wrote this is that over the years I have been here, you seem emotionally charged against 4/3 and Olympus. The comments in this thread - about a stuck pixel - would seem to support this. You have sidetracked and pushed the idea that anything is better than Olympus.
There is nothing in what I said which indicates that FT users can not happily use their OM lenses. If you know anything about history you should know that I was a huge fan of legacy lenses and other OM gear long before you entered the scene,
I recall your many, many posts and dissatisfaction with Olympus. You are one dissatisfied user. There are others. There are many, many happy users.
but fact is a fact, and there is a huge room for improvement and we all know by now that there will be no improvement in that department.
May be true, but irrelevant to the thread.

Likewise for many wireless triggering and many other options any camera system may have.

Ad hominem attack - anyone who disagrees with you is narrow minded/biased/stupid.

No. Only you mentioned them.

But you have bashed Olympus on this thread and are entirely off-topic.

Well, there you go again. Is Olympus "Special"? Many people think so. You don't.
Too much emotions in your post... ;) but that's OK, after all this time on this forum, I am not surprised.
Again, with the ad hominem attacks. I disagree with you, so I'm emotional.

The reason I wrote in this thread is that it was a perfectly normal request from a user about a hot pixel problem. The user was probably delighted to find that the manufacturer had built in a function to resolve the issue. I guess he was happy. (I don't know, as I haven't asked him: I think it's a fair assumption.)

Then, you enter the thread and bring up unrelated issues and, it would seem, try to promote Olympus as a poor system and many others systems as better.

There is no rational reason I can deduce for your comments on this thread other than a lingering dislike for a brand you no longer own.

I also know from your history that you don't like to let go when challenged. So, please re-read the entire thread and ask yourself why you wrote what you wrote as a rational and informative response to the OP with his stuck pixel question, or the poster who mentioned he liked his previous OM camera(s).

My E-1 has also reset once the hotpixel mapping database when I've forgotten to switch it off in view mode and left it with flat batteries for a week. Then I've found quite a few hotpixels on shots following this date. Then I've found a forum here on dpreview which exactly confirmed the same behavior due to a flat internal battery which holds this info. Since then I am cautious not to store my E-1 for longer duration with exhausted battery.

Regarding other brands, Canon does have a non documented but user reported feature, which practically initiates the hotpixel mapping function upon starting the sensor cleaning mode (open shutter & mirror-up) from the menu. Some report this happen and some do not see it, but surely there is a FW-version linked feature like that.
 
...they are just machines, be that Nikon, Canon, Pentax, Sony or (sorry to say) even Olympus. We are obviously not on the same wave length, not even near, so it is pointless to carry on. Either you don't want to understand what I am saying, or deliberately misinterpreting just for the sake of arguments. Your interpretation of my messages is totally differently from what I meant or said. Ripping apart my posts into small parts to fit your agenda is very annoying and not even worth trying to re-make them into some sensible messages.

Have a good day.

[Looks at two battery-less E-1s.] Ah, cr*p.

Oh well, good to know that I'm not completely mad.

Yet.

Muahahahaha!

You'd assume that other manufacturers would see such a function as a "good idea". It's a PITA to not be able to fix these yourself.
