I wrote about one of my favorite little quirky technological in-between eras.
I love awkward little in-between moments in technology. One of the funniest was a two-year period (about 2006-2008) when all filmmakers used these things called “35mm adapters” mounted on camcorders. Here’s a picture of one setup that I used to use. 👇 
That little metal monstrosity in the middle with the M on it has a 9 volt battery spinning a piece of ground glass inside. You can attach old Nikon lenses to it. The back of it is a macro adapter that screws on to the camcorder. 
This let us actually get larger image circles into our tiny-sensor camcorders literally by making a tiny movie theatre inside a black metal box and filming it with the camcorder. The results were beautiful though. 
So we kept using these goofy adapters until Canon stopped being idiots and this brief awkward moment in history was over.
Still, there’s something I like about the 35mm adapter over the 5D. Something analog about that ground glass (but losing 3 stops of light was a bit much 🙂).
