cymatty, as your in sheffield i would pop to harrisons on London road they will be able to help you out im sure! helped me out a few times
It's not all that hard todo, Just make sure you lock the Sensor in the options of the camera while you clean it, Just buy a small kit from a Photo shopand watch some Utube videos
.
Make sure you have a full batt when you start also, And a blower, If you're unsure just get a Pro todo it, As the kit will prob cost you more anyways.
so which kit did you go for in the end?
mine really needs a clean too!, have had a quick go with blower got rid of some.
thanks i will have google for kit
