Hi Astro-lianos,
Im thinking of replaceing this lens as it has kinda seen bettera days !
I bought it relitively cheap many thousands moons ago as it already had some coating damage and has worsened considerably since.
Or maybe Lenses like these can be recoated

I havent even checked if its a double are triple lens system and if need replacing or coating - id assume it be done to only the front lens ?
Any insight/weblinks appreaciated muchies
