Tack för tipset, Johan. Jag börjar med det då.

Hi, I'm writing this in English because otherwise it'll take me all day to try to get the Swedish right. Feel free to reply in Swedish though. I have a Canon 6D with some quite new Sigma lenses (Art 50/1,4, 35/1,4 and 85/1,4). I had some focus problems a while ago so I sent everything away...
