@Vitaliy_Kiselev Yeah, Cokin filters seem to be the way to go if you're on a budget. Plus you can get mattebox-like rectangles which clip on if you want some cover :)
Pretty useless if you can't put any filters in! You then have no control over shutter speed/aperture. You'd think it wouldn't cost much to add a couple of slits in it...
I bought it yesterday for the FF and Cheap rig also posted here, so review coming with that as well. And the 5" monitor. Stop posting cheap deals please VK , can't help myself. ...haha :-)
I think more people have been interested in my case full of lenses rather than my matteboxes. I always get suggestions such as "why do you have so many lenses? You do know you can get a lens like my _______ camera came with and it's a zoom and can do from ______ to ______ and it's the best (only) lens I've ever had! blah blah blah blah"
or
"hey, those lenses look expensive.. If you were to sell them on ebay, how much do you think they'd be worth....?" *looks around suspiciously*
The one thing about a mattebox . . . it makes the clients think you know what you're doing. A mattebox combined with spewing some random technical jargon about the firmware hack will keep them out of your hair.
