Ok, if someone can please help me. I'm very new to all this, and I'm just really more a director than cinematographer, but I just bought an HV20, and the only thing I hated about it was I can't really pull focus and get as nice shots as with this 35mm Brevis lens! The footage looks fabulous for such a cheap little camera.
BUT, I went to the cinevate site, and the front page shows a small lens, I click it, and it takes me to a diffuser. Is that the lens? I looked over the whole site, and I can't find the lens, but diffuser doesn't sound right.
However, what would be a huge help, if someone could, is give me links to all the things attached to the camera shown in the pictures above. The lens, the battery pack thing where the XLR cables seem to plug in, the tripod, the mattebox, any filters (if any) etc. I just want to know where and what I can purchase for this little HD camera to make the shots look that much better.
I know these sound like really stupid questions, but any help would be so awesome. Thank you

I really want to buy this lens and some of those attachments so I can produce some nice stuff.
Edit: Just to add some more questions. I also don't know what some things do and why they're required. A step up ring? What's that do, and why do I need it? What's a 72mm achromat? I went to another thread linked from here with a list of links, but I don't understand what each thing does.
I want the setup shown above but without the HD monitor and I'm not even sure if I'd need the battery in the front then if I have no HD monitor, but correct me if I'm wrong.
