<p>I have a K-5II and have had the opportunity to compare my HD DA Limited's and DF A 100 Macro WR on a friend's K-3II during indoor shooting in an arena. The AF on the K-5II was a big leap from my previous K-100 D Super. The AF with the K-3II was a very noticeable improvement over the K-5II. The Ltd pancakes are blazing fast on a my K-5II so I was quite surprised. As a result I will be searching for Black Friday, Cyber Monday or Boxing Day deals on a K-3II.</p>
