How serious is dust in lenses and what is the approx cost (if any member has any idea) to have it removed- if possible? I am referring to rear element dust.
I am asking this as I am now missing my 300mm f4 IS USM lens and have recently been offered a 300mmf4 non IS lens at a very reasonable price. The only problem is that (a) the manual focus doesn't work- must get it repaired for my own comfort (b) the rear element has got some dust. Apart from that, the lens works perfectly and the AF is a peach- no problem. The dust doesn't affect the pictures.
Many thanks
Nathaniel
