I dont know much about the Sony line up but, its pretty likely for the budget that's implied that a mid length prime might be available capable of producing quality shots and something that could be grown with. Quality lenses that cover wide focal lengths are very expensive and not terribly common. I think people sometimes get frustrated that they can't create things that meet their expectations with these compromise lenses. I think maybe it's more fulfilling to give up some reach but, be capable of producing quality work within those limitations.
