I left my 85mm f/1.4 at a clients house, on the lawn, for two weeks or so. Awesome! It still works, but its really hazy and I can see water spots inside on the glass.. its just not clear to look through. I have received trusted advice from Bjorn Rorslett (anyone know better than him?) that it needs professional cleaning... but I am dreading the Nikon $500 estimate that I assume I am going to receive. I emailed an estimate request to phototech (I live near NYC) but I was wondering if anyone had any thoughts on who should do the cleaning and if a third party is worth the risk. Any similar experiences out there?
