I think using a zoom is harder than a prime lens. It adds yet another variable to the whole process. Some day I might be good enough a photographer to effectively employ a zoom for concerts, for example. Otherwise, I prefer primes. I’m no prime snob but there are several reasons why I like them better in general.
But, really, it was the second part of the quote that made me post this. Thin depth of field is often a dodge, as Stella says. Not always and sometimes it’s an effective tool but to me it’s sometimes simply an unwanted side effect.
