<p>Thanks for the info, Mark. I guess that means UV filters are pretty much useless in that respect? Or do they manage to block certain wavelengths of UV that DO make it through the glass? <br> In any case, I've been shooting with the fungus-infected lens and, despite the large amount of visible fungus in the rear element (as you can see in the picture I uploaded), the image quality appears to be just fine. Here's an example if you're interested: https://www.flickr.com/gp/123858405@N08/32942P<br> Initially I was planning on getting the lens repaired, so I went back to Mamiya's service centre in Tokyo. However, it turns out the cost for repair (since the 50mm is quite a complicated lens with a floating element) would be about 260 dollars. I could probably find a good replacement on KEH for the same price, roughly. And besides I'm happy with the lens as it is at the moment. <br> Thanks!</p>
