I also have DSC-P100 camera And i don-t know why but the other day it gave me E:61:00 error I thought thats it, i need a new camera, other then the error, camera was completely out of focus. So i searched on google and came across this...and ACTUALLY hitting the side, where the lens is, couple of times with my hand, and then turning it off and on and it fixed the problem...HAHAHAHAH I cant believe this...thanks guys....hahaha

hello ihave the same probleme with my camera sony syber-shot dsc-p100 (e:61:00 error)plaese if you can help me to resolve this probleme send me an email thank you very much

Beleive it or not banging the side of the camera a couple of times on the side (next to the lens) worked for me and apparantly many others. Three slight bangs on a table top and.....no more error message & welcome back auto focus.

I had to drop my T1 12 times at 3 feet. it works now. sony offered to fix it for $171.00
