Right now I got the 18-55/4.5-5.6 IS II kitlens but I don't like the quality of the picture if gives me. I did own a 70-200/f4 non-IS before and I liked it but got dizzy because of the missing IS in the viewfinder. I have ruled that one out because I will not always shoot with good light.
What is the best prime choice for me? Like I said in the title I like to take portraits and some action shots, I stay rather close to my dog so a zoom will not be necessary.
