I've got the K 400/5.6, Tokina SD 400/5.6, and the Sigma APO Macro 400/5.6. I've been very happy with the Sigma, which seems to be significantly sharper than either of the other two. I had a problem with mine, apparently after a hard knock, where it wouldn't focus to infinity. It was about six months out of warranty, but they fixed it at no cost anyway. TTYL, DougF KG4LMZ
