Chosen Solution
I get an Err 30 while taking photos. I can shoot 100 or more photos, then Err 30 starts popping up every few tries. I take out the battery, replace it and restart. Usually camera will work for 10-100 more photos.
Problem has gone away. I blew out the camera with a can of compressed air for cleaning PCs. I am planning on sending camera to Canon for a thorough cleaning and recon. Have a MK II ordered.
Working solution: Go to Menu and select the Clean Sensor Manually. It really worked for me!
I just had this problem. Your shutter is failing, and will eventually stop working altogether. I had to send my camera body to Canon for them to replace it. Not an inexpensive repair, but it is a GREAT camera well worth repairing.
I fixed this. just take the lens off, manually move the shutter up and out of the way. Look to see if there is anything blocking the path of the shutter (behind the shutter) (I found a little piece of something that was blocking my shutter… I removed it and voila, the camera works again.
I bought a EOS50D in 2009 and recently, maybe about 6 months, she started with this error 30. When this error appears I turn off and turn on the machine and it solves the problem. As I have already taken more than 50,000 photos with this Canon, I believe that this problem is acceptable and even expected.
I had the same issue with my 1100D. I tried all the solutions mentioned in various forums. One of which was the manual cleaning of the sensor. And that is when I noticed that the shutter curtain was stuck and did not expose the sensor at all. The only options I had were to take my camera to dor repair, where I would have been made to pay whatever amount. Or try the repair myself. I opted for latter. I searched for youtube videos on how to disassemble the camera and operate the shutter curtain manually (there is a motor and gear assembly that you can turn or rotate with your thumb). I noticed the curtain would not open still. A closer look revealed a small rubber piece stuck on the upper edge of the curtain. After removing it with a pair of tweezers the shutter curtain started to operate again. Now I again have a working camera and two offspring screws which were left behind and I absolute can’t remember which part were they securing. Well, those have carefully stored just in case I remember where they originally came from.
I also have the same problem with my 5d mark iii error 30 keeps popping out even if I replace the battery. So I removed the lens and raised the camera mirror up, I found that the sensor cover was squeezed. I straightened it. Buh the upper one is not as tight as it was. So every 3-4 clicks then error pops out again..
i had a similar issue on canon 1300D .. I tried replacing the battery. it did not work. I took it to a repair guy in Bangalore .. it cost me 5950 rupees to change the sensor, which is quite expensive.
Hello, I have this prob when I reassembled canon to fix other issue. My plug [red square] was not clipped correctly.
