Again, that will depend on how big the difference. Digital SLRs tend to have the same lens mounts as their 35mm film cousins. You can use 35mm Nikon SLR lenses on digital Nikon SLRs, for example, even though the digital Nikon has an APS-size sensor. And that works quite well, according to the reports I've read. So as long as TV cameras use APX or similar sized sensors, in favor of the tiny sensors of the old days, lens costs should not be an issue for 1080/60p cameras, I don't think. We can quibble about 24 X 36 mm vs 18 X 24 mm, but lenses for these formats are affordable and easily capable of handling 2 Mpels, I do believe.

Also, there is no excuse for rudeness. None. You will note, the rudest posts are ALWAYS wrong on this list. This has been true from day 1. Rudeness does not mask cluelessness. Quite the opposite.
Once again, Bert has demonstrated his willingness to engage in a discussion about which he is clueless.
May I suggest that Bert read a very good series on HD lenses written by Larry Thorpe and Gordon Tubbs.
