Just wanted to say thanks for the guide and the detailed info. Having the same issues with 5000, but considering I bought it for 3 pounds I think I cannot complain.
I first thought that the lens was defective (it had drop damage on it), so I jammed it to be always open. Got a new one hours ago and same problem - so thank you. I'll see to fix it in the next few days by cleaning.
