Thank you for showing the Hoodman. If I get one I'll have to find a source of large elastic bands!
As you mentioned the Sigma ring-flash I thought you'd like to see a picture of it on my Sigma DP3M. You can't see much of the DP3M!
Like all Sigma kit it is very nicely put together and even comes with a handy case (which you need 'cos it is large!).
I posted some results elsewhere in the thread. I am not entirely convinced it is a worthwhile purchase but on the other hand I have probably not invested enough time in really trying to get the best out of it.
I can just about hand hold the DP3M with the flash and have transferred my Milich grip to the camera in order to get a bit more control over the weight/bulk.
