Black spot for every photo

[sanath444]

I get a black spot on every photo I shoot with EPM2 at high f numbers. It appears on the sky. Is it sensor dust?











Would Olympus fix it under warranty or would it charge for sensor cleaning (although camera is still under warranty)? Doesn't EPM2 have a Supersonic Wave system that vibrate the dust off? Is the sensor, the rectangle I see when I remove the lens? Is low pass filter and the sensor the same?

Yeah, looks like sensor dust. It could be stuck on which is why the vibration system isn't working. If you take the lens off, are you able to see anything on the sensor? You should try using one of those rocket air blowers first. That'll work if it's a dry piece of dust. If it's stuck on, you could risk doing it yourself or take it into a camera shop for cleaning. I doubt Olympus would clean it under warranty, since it's not really a manufacturer defect or anything.

I actually had something similar happen on my E-PL1 and I didn't feel like forking over big bucks to get it professionally cleaned, so I took the risk and tried cleaning it myself. I had a lens tip pen that I used very carefully and I managed to get it off. It was stuck on good too, probably a wet piece of dust that dried and stuck to the sensor. Took a few rubs to get off. I'm amazed I didn't damage anything [I DO NOT RECOMMEND DOING WHAT I DID]

Olympus should clean it for you under warranty, but you're responsible for shipping.

Thats NOT sensor dust, it is on the back element of your lens. It varies, as you said , with F stop. Clean the lens. In the old days,remember what dust on a negative looked like? It was never a blob like, out of focus image. If it were on the sensor, it would be sharper in focus. I highly doubt the dust is on the sensor, how do I know? BTDT

Dennis may be right. I can almost imagine seeing the blades of the aperture in that spot.

If it is from the lens, try a different lens and see if the spot persists. If it is on the sensor, it could be sticky dust, such as pollen.

Last time I attempted to clean a sensor myself, I made things worse, but that's just me. I'd be inclined to live with one or two sports on the sensor, cloning them out in post. Of course, if you afford the inconvenience, Olympus can sort it out for you.

It is dust on the bottom center part of the sensor.

The simples way to confirm is to switch the camera off, remove the lens and point a bright led torchlight on the sensor. You should be able to see the dust when you move the light around. Just be carefull not to breath on to the sensor.

Depending on the type of dust you may be able to remove it with a blower. Turn the camera with the sensor pointing down, use a few blows into the sensor opening to try to remove the dust. Next use the torch to confirm that the dust has been removed.

If this does not help then are several options like sensor pen or wet cleaning but in your case it maybe better to send in the camera for a service.

I personally have used the blower and LensPen SensorKlear to clean the sensor on my Panasonic cameras successfully.

Just curious: what do you folks in England call this item? This what is known as a torch (or blowtorch) in North America. It would certainly get rid of the dust spot, LOL!

I think this product may work to remove the dust, but it may do some more unintended damage.

This product is more suitable:

Usually call that either a Blow lamp or a Blow torch

I think both words come from the times when Light came from lighted fuel lamps/Torches before Electricity and got carried over to the new fangled Electrickery ;-)

I believe over the other side of the pond the word used for an Electric Torch is a Flashlite ????

"Blow lamp"? Now that's just silly! 'Almost like they got caught in a quandary and didn't want to switch labels midstream.

Not that "flashlight" gives a perfectly clear meaning, either — but "blow lamp" takes the cake, here.
