This is ridiculous. Panavision lenses certainly have many advantages for film production, but calling Canon glass unsuitable for a large projection makes zero sense.Comment from Shane on his Blog: I have stopped using all Canon lenses because I feel that they are too soft when it comes to projecting the image on a 60 foot screen, this is why the Panavision Primos primes are my go to lenses of choice.
Even a 4K digital projection doesn't have anywhere near the 20+ megapixels that these lenses have to resolve in still photography. I wouldn't be surprised if Canon L whooped Panavision's butt in a direct 24 megapixel comparison.
