I have seen a nice Rolleiflex today with very clean lenses. But I have been told they have been cleaned to get some haze remove. Does anyone know if I should expect this haze to come back? Is such cleanup really efficient and permanent? I know all lenses will eventually get hazy, but will this happen again sooner than average... Also, do you think this treatment may have affected the coating? There is still the purple shine on it.
Thanks!
