randombro: worked for me! got a used 40d for under $100 "shutter button dead, everything else ok". poured some lighter fuel in and now it's 100% perfectly functional again.
Filip Sałapa: Thanks for making the effort showing it to all of us - much obliged
Ivo Orellana: Hi..!! I think I'm having the same issue with my canon 70D but also the touch screen and any other buttons on my camera are not working is it because the shutter button is not working right ??????? (the shutter button only takes pictures but it doesn't focus)
has anybody had the same issue or would this work for my canon 70D ??
Ronnie Guzman: My Nikon D300s will not fire instantly using the shutter button so I tried this method last night and it works brilliantly... thank you for posting... save me some $$$$
kaiyum kureshi: Hi, i am having some problem with my Canon 600d. suddenly my camera showing some error "Err 30 :Shooting is not possible due to an error. Turn the camera off and on again or re-install the battery." display working fine but live view is not working,sensor cleaning working. can u suggest me any solution??
Tim Garr: This is a great tip, but try changing the CMOS battery first. I changed the battery because my flash wasn't syncing with my camera as well, interestingly, that fixed both issues.
Trần Anh Vũ: It works perfect on my 40D, tks very much, I 'm from Viet Nam
