Leica Summicron-R 2.0/50mm on Leica SL3

Sean Reid just published a review of this lens/camera combo, and I believe it is fair to state that lens perfomance is far below what one could expect.

While I normally enjoy reading his reviews, this one is in my opinion completely meaningsless. He states in the beginning and also later in the text, that the lens was dirty and full of fungus. Why bother to test a lens which is damaged? No wonder performance is bad. It would have been nice to know how a clean Summicron-R 2.0/50mm performs on an SL3.

I wouldn't even have a fungus ridden lens in my house, let alone on one of my cameras.

The "infection" is a bit of a myth. Fungus spores are everywhere, in your house as well, regardless of the presence -or not- of a fungus-ridden lens. Still, I can imagine that one feels uncomfortable by the proximity.

Yes, I understand that this is correct, but testing a fungus infected lens still does not make much sense.

Jaap, indeed so - it's the uncomfortable feeling, however needless the worrying may be!

Fungus spores are everywhere, but doesn't it make sense that the kind of fungus spores that thrive in lenses would be greater in proximity to a lens that already has fungus? Perhaps the fungus in the lens itself is giving off the spores? I wouldn't really go crazy over it, but it does seem reasonable to consider it at least. 

As for the review, I no longer have a subscription, but it is a bit odd to review a dirty lens with fungus...
