Only because they are shooting with someone else's money, and being paid to do so!

The real guys
 

Charles, I'm thinking og "guys" such as Eric Rohmer who's past 80, has been shooting one or two movies a year on tight budgets...what a lesson in dedication to movie making! And think Rohmer has always limited himself to 35mm-50mm and very seldom used 80 or 95mm lenses. No telephoto, no zooms (except a couple of time), no fish eye, no steadycam, no trendy rack focus (I feel sick of all these rack focuses for the sake of rack-focusing), alot of imperfection in sound (he says he is insisting on no frills intelligibility), and simple choices of dominant colours. It does not matter if some of his movies are sometimes as soft as a Letus35 smeared with vaseline. It's still great art. And look, Rohmer's movies are selling like pain au chocolat on DVD.
Conclusion: too many lenses (too many tools) might kill artistic expressive power. A few well chosen good lenses used carefully could make the difference.

Chocolate covered bread sells well?

Bill, not bread covered with chocolate, but chocolate covered with bread.

or as babelfish translator would say: "bread with the chocolate"
but up here in french canada we know it to be a French bakery favorite, chocolate wrapped in pastry.

Weighing in a bit late here on the multiple lenses, but...

The scene I shot from "the letter" used canon fl 50mm, 85mm, 35mm, 28mm, and a macro attachment which was great for the real close-ups. Works with all lenses above as an attachment. The overhead shot is the 35mm lens.

Dude that music is some of the most melancholy shit ever composed. I can't watch the Elephant Man without balling like a baby when that music kicks in at the end as he lays down....I hate you Brian...you've given me the weepys!

Greg - put it on mute - just think about the lenses, man, the lenses! :)
