I think the answer is "it depends" but if you have a camera body already that is 100% compatible with this lens then the lens is easily where I would go first with my money.
*This is not a complaint about anything, just stating my position*: If I could use this new lens with my K-5 II I would definitely spend the money on the lens and use it on that camera. As I cannot my plan is to get the K-3 III and a Sigma 17-50 at some point as a much lower cost alternative lens. Eventually the new 16-50 is what I would want to pair with that camera body.
