Originally posted by pentaxman The item pictured in the ad is the Sigma 400mm F5.6 APO Tele Macro. The 72mm filter is an error, or the photo is an error. The filter size should be 77mm as several people have posted. I have one and I like it a lot. What other lens can you take a 1:3 macro shot from 1.6M away! The focus is fast and accurate although it can tend to hunt in poor light.
Thanks for that input. It confirms what I thought - they must have the filter size wrong. The lens pictured is the 77mm version, and the 'APO Tele-Macro' name also only belongs to the 77mm version.
From what you say, the lens sounds better the more I hear of it...
It's also interesting that the store is only advertising it as available for Pentax mount - not Canikon/Sony. That's gotta be a first
I retain a degree of scepticism about the real availability of the lens though. I fully expect an email from the store any day now saying 'sorry, we got it wrong, the lens is not available any more. We need to cancel your order'.
