So after fixing the focus on my 85mm (+7) this lens has been glued to the 7D. It's sharp as crap and super fast focusing which means it keeps up with my running around kids great. I now take it to 1.8 without any worries and the 7D AF nails the focus like you wouldn't believe. I have been learning alot with the my new 7D and how the AF works and I'm super impressed, however, now that I'm having such fun it makes me wanna ditch the Tamron and get the sig 30 1.4 or the canon 28 1.8. Maybe because I haven't dialed in my zoom's yet but it's just so reassuring that no matter what I throw at the 85mm that it just works. I want that for a normal range lens and I really want the 28/30.
I only have budget for one right now so I'm really thinking of selling the Tamron and going to a prime only main lens. am I committing suicide?
