    taking apart a Nikon ED50 (fungus inside)

    Time for an update! A friend of mine needed a small scope for travelling, and I allowed him to try and open it, as I deemed it 'written off'. What he found was not fungus, no oxidation, but... grease! Some grease / oil seemed to have been leaking, coming from the focuser. In order to open the...

    taking apart a Nikon ED50 (fungus inside)

    Thanks but that's not good news indeed. I recently found the Nikon contact info. I will either bring it to the Nikon repair centre (and they will, according to the website, give me a quote before repairing), or either try to find a second hand ED50 for a good price. I'll keep you all updated...

    taking apart a Nikon ED50 (fungus inside)

    Hi John, I thought about that, but with a buying price of 330 euro back in the days, I would rather opt for a quick opening / inspection, and only if that doesn't work, to contact a Nikon dealer. Nikon isn't known for great customer service, and I can imagine the cost of repair being rather...

It was present for some years but stayed at around 1/3-1/4 of the total surface, and thus it didn't bother me at all as I didn't even notice...

    Thank you gentlemen, I will make better photos tonight (photos above were take with my phone, but I have better equipment available). Meanwhile, after Hermann's reply I searched a bit, and found this: Nikon Fieldscope ED50 Separates Probably, what I see, when looking through the objective...

    taking apart a Nikon ED50 (fungus inside)

    Hi all, contrary to what some may think when reading the title, I haven't taken the scope apart (yet), but I'm planning to do so. ;) After 14 years of duty, the fungus has decided to grow just a bit too hard, and has now covered almost 100% of one internal lens surface. The problem is that...
