How about the Opteka 420-800, http://opteka.com/420800.aspx , a bit lacking at the short end, but only 520 g, definitively hand-holdable, no carriage needed.

 

Or the Opteka 650-1300 a tad heavier with 2kg, near hand-holdable. <_<

oops, here is the link: [url=http://opteka.com/6501300.aspx%C2][/url] -

I think this is made by acclaimed lens producer Samyang, though for some unknown reason they don't want to show that anymore on their new Samyang web site.... maybe they are a bit shy.
