Hi all. I'm looking to upgrade/change/renew/etc some of my equipment later in the year or early next year. I would like to get a wide angle prime for my 5D (or hopefully 6D at the end of the year), somewhere in the range 14-17mm. I can't afford the Canon 14mm, so I'm wondering what other options I might have. It will be for landscapes, so manual focus is ok, but I would prefer it to be able to meter through the camera/lens. So essentially, it doesn't matter what brand or age it is, as long as it can fit the EOS digital (via adapter if necessary). I'm after the best quality I can afford (aren't we all? ), so I'd like something that is sharp across the frame either wide open or, more likely, within a stop or 2 of wide. Any good lenses you can recommend?
