A friend of mine recently acquired a Nikon 35~70mm f2.8 AF zoom (the earlier version, not the AFS type). Anyway, noticing that his pics weren't as clear and sharp as they should be, he examined the lens and noticed that one of the inner elements appeared 'cloudy'. I checked it over myself and it does indeed look like some kind of crap uniformly covering one of the elements. I suggested that he send it away for a CLA, which he did. When he spoke to the repair bloke, he was told that this was a not uncommon fault with this particular lens and that the element in question had 'deteriorated' (sic). I don't want to impugn this guys reputation without first asking you lads 'n lasses what you think. To me, it sounds a bit odd. I could understand this on a really old lens, but this one isn't that old. Are Nikon pro lenses (or any pro lens for that matter) subject to this kind of failure? As ever, your opinions are greatly valued. Regards, B.
