I was just wondering if anyone has this lense in particular. I've been talking about getting the 50mm 1.8 for some time now, but im starting to second guess myself on the mark 1 or the mark II. The mark 1 is a little bit more expensive than the mark II and apparently is more durable than the mark II. This link has all the details about both.

Any help is appreciated.
