LF and MF are indeed separate, but in the same place!
Once we get enough in each, we'll split them up if people want.
It all depends on how much the LF is used with Digital Backs or else, with film, the old fashioned but tried and true way!
Today, architecture photography might use a variety of camera platforms but the same digital back with adaptors. So in that sense, MF and LF belong together.
Rainer, for example uses a multishot Sinar back with a specialized LF camera so he has very precise movements and can use modern digital lenses. He has the possiblitlity of using that back on other bodies.
With film as the recording medium, it did make much more sense to separate camera platforms. But today, digital backs are the common expensive denominator with the platform being that tihng between the seonsor and the special lenses.
Wil Thompson and Erik DeBill are each active with LF, but use film. We want people to pull out their LF cameras, and prove that it is yet possible to work with film and do magic.
