I'm curious, Alan -- when you take off the hood on the 400, how much longer is the 400mm + 2x than the Sigma (with no hood)?
I've wondered how critical the hood is and have pondered making another that is maybe 1/2??

The dimensions can be found in TDP, imaging-resources etc. The 400mm DO II is 233mm long, vs 267mm for the Sigma unextended (I have checked). With a 1.4xTC on the 400mm, they are the same length. Without the hood, the 400mm DO is quite short. I value that front element too much to use the lens without the hood.
You do not lose much. The lens weight as well as its center of gravity remain practically the same since the hood does not weigh much. I always use the hood and it is still a pleasure to use (at least comparing with the 500II ;D )gruhl28 said:AlanF said:Jack Douglas said:Talys said:AlanF said:Jack, I don't fear theft.

I can certainly understand not wanting to walk around without the protection of the hood, but I can't help wondering if Canon had to make the hood so big - it almost doubles the size of the lens. I guess it reverses for storage, but it still seems a bit of a shame to have to lose the smallness of the lens while using it.
Edit: Not that I'd mind having a fantastic lens like that.

AlanF said:That's a very fine shot, and in my many sightings of a kestrel I have never seen one with a kill. The quality is superb. Is it a 100% crop or is down-resolved?
My guess is either black-tailed or blue-grey gnatcatcher. Do you have a pic showing underside of its tail?clbayley said:I have another Mexican bird to show, but I can't ID it...I hope the collective here can help. It has very tiny, hanging in scrub bush, and had a very pretty voice...any ideas?
