While the 2" diagonal dwarfs the C90 it is still light enough to work well on a photo tripod fluid head. -------------------- 'these things stand like stone - kindness in another's troubles, courage in your own' Gordon Post Extras       Entire thread Subject Posted by Posted on orange c-90 question bobbyt 08/06/08 06:12 PM Re: orange c-90 question BRisley   08/06/08 10:30 PM Re: orange c-90 question albert1   08/06/08 11:34 PM Re: orange c-90 question Dubboy   11/03/08 07:33 AM Re: orange c-90 question Jay_Bird   08/10/08 03:48 AM Re: orange c-90 question clang   08/26/08 02:02 PM Re: orange c-90 question Jay_Bird   11/03/08 04:23 AM Extra information 3 registered and 7 anonymous users are browsing this forum.
