I get the feeling it was made before the advent of those.
If you're referring to my comment about the summit ridge then it's true that a wide angle lens would make it appear sharper than reality - indeed there was a helmet cam clip of the Nadelgrat recently where this was certainly the case. However, in this case I was remarking that it looked a lot LESS sharp in the film than my memory of it. I suspect that it just tends to form differently from year to year. I do remember it being uncomfortably steep on the Whymper side so after a distance I crossed over to the Argentière side expecting it to be much more friendly, but to my dismay, it wasn't!
