This is true. The 10-18 has a rather close focus distance at the wide end compared to the prime. Don't know TDP's testing methods enough to know if this is a factor. Christopher Frost's and Gordon Lang's reviews were more favorable of the prime at the edges.
Edit: I compared a couple more Sigma primes with closer focusing, if slower, counterparts and noticed the same behavior. Perhaps TDP is not the best tool for these lenses. I'll add though that I compared the Sony version and it seemed to perform much better. It the R7 too much for it? I have no doubt that all these Sigma lenses are very good.
