Are Lenses Holding Back Megapixel Cameras?

I saw the discussion about the lens limitations and it reminded me of a discussion I had with a lens manufacturer about 4 or 5 years ago. This manufacturer stated the megapixel camera's imager chips are out pacing the technology for lenses. The lenses are glass and cannot keep pace with the chips. He said megapixel lenses were in reality limited to 3 megapixels due to the physical properties of glass.

Since there were 5 megapixel cameras out on the market, I wondered about their truthfulness in advertising. I looked at the websites of these camera manufacturers and compared their stock photos taken with their cameras. In my opinion, the 3 megapixel was better than the five in almost every photo I saw.

I remember talking to a FLIR rep and he said essentially the same thing but their breakthrough was using Germanium lenses for their thermal imagers.

Today, a short Google search brought up interesting results. There are still limitations but no one can agree with each other as to the megapixel count. I have seen claims to 3, 5, in the CCTV industry and 21, 24, in photography.

Has lens technology been outpaced by megapixel imaging chips?
