At the bottom he mentions the newer current 40-150 model, which he says is somewhat better than the Sigma optically.Myself, I have the Oly 40-150. Very nice lens, and I think if you shop around, you can get it as cheap or cheaper than the Sigma. I got my 40-150 for $115 from Amazon about 3 months ago.</blockquote>
