Lens polisher

[JJLoke]

I would like to ask where I can buy lens polisher. I have an old Canon SLR lens which is very blur (light scratches and stuff like that), wanna polish it till clear again.

Thanks

Lenses typically have a coating. I think polishing it will affect that.
You can bring it to The Camera Workshop in Peninsula. They may be able to help.
cheers

hmm .. the coating has wear out completely (tint of yellow left)

since its old, i dun mind rubbing off the coating, jus for fun and experience

Was this len's coating yellow previously?
Back in the old days before new technology in coatings was available, some manufacturers like Pentax OEM use a low level radioactive substance to give the lens anti CA properties. However, with time, this material turns yellow.
The treatment is to leave the lens in the sun for a few days. Direct sunlight changes the yellow back to clear.

will try it out when the sun is not covered by rain clouds

meanwhile wanna get some glass polisher for fine scratches

Probably Spectacles shops can help you.

as far as i know.. polishing lenses need a constant flow of clean water. They also have a curved 'polishing block' in the shape of the lens and it's a highly specialised job.
