[QUOTE="AC016, post: 144333, member: 9619"] I have looked on the interweb concerning this subject once before. I did not find any hard evidence that said any one particular lens contained plastic elements. When i say "lens", i mean an interchangeable lens. It is well known that aspherical plastic lenses are used in inexpensive conusmer cameras (P&S), mobile phones, etc. Hey, not to many people i know have actual glass lenses for their glasses - safety reasons. Therefore, if Canon states that they use plastic lenses for their optics, i would imagine they are talking about their consumer P&S cameras or even maybe their cheapo DSLR lenses - if they put them in their L lenses, i think people would have a heart attack, lol. I really think that you would have to be somewhat of an expert to really debate in technical lingo, about the presence of plastic elements in lenses and whether or not they are compatible optically with glass elements, etc etc. None of us hear are optical experts with any sort of degrees in the field - if any of you are, pls raise your hand... Just ask yourself this: does your lens perform as advertised? If so, who the hell cares what the elements are made of. I highly doubt that anyone here could tell the difference anyhow. [/QUOTE]
