Anyone out there heard of this? I just had two of my L lenses appraised for trade-in: 1. My Canon EF 85mm f/1.2L II USM (which I LOVE but don't use enough to justify the capital tied up in it) 2. My 1st-gen Canon EF 70-200 mm F/2.8 L IS, which I was contemplating trading to the new version (in part using the proceeds from 1). Weirdest thing. The appraiser - who I do trust - came back saying that, whilst they were both "mint" from a cosmetic and IQ perspective, both lenses showed signs of slight moisture ingress between elements i.e. mid-lens. I am mystified. Despite owning this lovely glass, I pretty much shoot all the time with my 24-70. Both the 85 and the 70-200 live indoors, in my study... it's in a centrally-heated house which is always warm and dry... they live inside their protective case (70-200) / pouch (85), respectively inside a closed office cupboard... the cupboard is nowhere near an outside wall... bone dry and dust free. To be fair, I took the 70-200 out once in the last two months - to photograph a game of rugby - but the weather that day too was dry, warm, sunny... the lens went to the match in my Tenba bag, came out for fifteen minutes, then went back into my Tenba bag (which I promptly zipped tightly shut - even though it was warm and dry). On the other hand, the 85 has not been out of the cupboard, let alone out of the pouch or out of the house, for probably a year or more... and prior to that, it has never been used outdoors and certainly never in the rain or even in the damp or cold. Has anyone ever even heard of such a thing? I have an engineering / science background and I know water can't just come from nowhere. Added to which, these are L-series lenses so even if they had been exposed to dampness or humidity or light rain (which they have not!), surely they are designed to shrug this off without a blink? Would value opinions on this since the assessment is probably going to cost me the best part of $1000 by the time they are shipped to the specialist for inspection, repaired, reassembled and returned. And I wouldn't mind if I'd dropped them, bashed them or hurled them around in the mud - but lenses don't get nicer, warmer, drier life than they get with me (because these days I find it hard to get out and take pictures due to other pressures). So... how???!! Thanks in advance, A
