A stuck lens happened to me twice - I dropped it twice!
After the first time I found a Sony service depot that told me it wasn't worth repairing, a $200 camera at the time (mine is a DSC-S600). I wasn't about to toss a Christmas gift from my kids!
I don't remember how I found them but twice now I've had the stuck lens fixed by "Home Electronics & Comm" at the Yorkgate Mall, northwest corner at Finch & Jane in Toronto, (416)665-5126. They repaired it for under $75 each time! Ask for Gohar.
