Wow, Back Alley! Really interesting link!

Anyone know of any similar articles about lens haze or fungus? How bad does haze or fungus have to be before it'll show up on a photos?

Fungi on your lens ? Have a look here

I have a Summar and Summitar that both have their fair share of cleaning marks and probably a little haze; with C41 black/white film they perform wonderfully, but I tried (once) C41 color film and the contrast was extremely low. Reminds me I need to sell them, though I fear trying to ebay these things...

I won`t even allow cleaning marks on my car

My car has no cleaning marks, as it never gets cleaned...
