I have not used the pro-shade with my H which is why I did not comment on that part. I have used the pro-shade with my V, frankly I found it a PITA to use. On the V, the shade was already almost useless with my 60mm. I also had to constantly check where it was otherwise I might end up photographing part of the shade. The thing also has a size that did not fit really well in most of my bags. I guess I simply did not like it and did not feel like exploring fully how to optimally use it.
I rather take of the shades of my lenses and use the Lee filters directly over the lens than use the pro-shade.
Maybe I should check one of these days whether it makes a real difference, using the shade or not.
If I have time this weekend I see if I can dig up the pro-shade from the rubbish pile and see if I can get it to work.
I just realized, you might want to know whether it fits sizewise? I will dig the thing up later this afternoon and have a look.
