    quality

    5 ppm and 5500 ppm are both ppm amounts. Just because you say you have it down to the "part per million amount" doesnt mean anything. 5500 ppm is roughly 5mg/g, which is a shit ton of interfering product.

    And before you go off on some rant of why do I care or I am bs'ing, I am a chemical engineer and I do material testing. We have contracts with quite a few lens manufactures to independently test their lenses for composition. I have dissolved and run quite a few Canon lens by ICP. Their composition varies. A lot really.

    Fucking cool.

    No wonder they cost so much, so many precisionly designed pieces of glass and a lot of hands-on assembly.

    well good for you, would you like a cookie? :ugh2:

    I'm sure they had the chemical engineer crowd in mind when they made the video. Actually, I think there is a chemical engineer sub-forum on dpreview that you might enjoy measurebating to.

    In your rush to "own" me you completely overlooked the point that was apparently too subtle for you. It doesn't matter if the lens has 1ppm, 7ppm or 50ppm of whatever in them. The lens they were talking about produces damn fine images, regardless. Caring what the chemical composition is of the first lens element has exactly fuck all to do with photography, I think you may be in the wrong forum. Go photograph some bench test charts and STFU.

    you know I always wonder why stuff like that costs so much untill I see how much work goes into it

    And thats completely wrong. If it didnt matter, the manufacturer wouldnt meantion it at all, much less in passing in a video release to the general public. You stick 50 ppm of an zinc/iron alloy in any of your lenses, your pictures will not be as sharp. End of story. That why I care and thats why Canon cares enough to meantion that they try to control the composition to an nondescript removal "to the ppm" and thats why my company get contracts to test the lenses independently.

    And, well, the rest of what you said was basically :ughj:
