hey, my 50-250mm lens have the same problem. How much do you think a shop would take to fix my lens ?

[checkmate3001]

@IFlatlineStudios I think you mean 55-250? I don't know without seeing it. It could be several things (main pcb, is unit, aperture unit). Maybe $100-$200.

Can you fix my Canon G7? Dropped it. Are you local?

[checkmate3001]

@villarte I work for a private company. I recommend searching online for camera repair in your area.
