Water Spots on Sensors
 

I saw some spots when I was messing around with shallow focus, that look like water spots on the chips... as the lense and filters are as clean as I can get them.... and I do not see anything in the lense.. very similar to my Nikon D100 when shooting in the Caribbean where condensation could form. Anyone else have this problem? I shot 10 days in Hawaii and had the camera overhalled at Sony.

Under normal shooting the focus would not be shallow enough to see this, but it still bothers me...

Confirmation
 

I can confirm that indeed, my EX1 also had the same issue. I would equate the spots, however, to dust on the sensors, similar to something you would see with a digital SLR.

I was still within the return period from the retailer, and will receive my replacement EX1 tomorrow.

Until I read about yoru camera, Greg, I thought this would be a one-time isolated issue, but it seems like this could be on ongoing problem.

I sent Sony engineers test footage from my EX1, and they confirmed that it did look like dust on the sensor. Considering that the EX1 is a closed lens system, one would wonder how this could happen. I just hope the replacement camera is dust free.

The same thing happened to me Carl. I had big chunks of junk on my sensor. It was visible only at full wide angle position and when the lens was stopped down. I'm now on my third lens with my EX1. Good luck with yours.

I just bought an EX3 recently and am very pleased with it except that I also have what appears to be a speck of dust (or water spot) on the sensor (or maybe lens?). Noticeable only in darker areas of the picture and at stopped down, wide angles as well.

Being that the lens is removable on the EX3, I was wondering if it was wise to blow compressed air in there to maybe remove it. Hopefully this isn't something I have to send in for repair.

Otherwise it's an awesome camera.

Do not blow compressed air into the camera... you could end up with moisture,oil or damaged parts...

There are sensor cleaning kits available on the net, you should also get a good bulb blower
for blowing off the sensor... I keep mine in a plastic bag so the blower won't get dust in it.

Here's a popular sight amongst the SLR folks for cleaning sensors....

This page also shows the rocket blower.. there are tutorials also on this site...
