Ah, this is my kind of camera - Paramender and all!
I figure that with an SLR, you lock up the mirror. With a Mamiya TLR, you employ the Paramender (to correct for parallax) when shooting up close. (With a Minolta Autocord, you employ a Paradjuster 😎 .)
Of course, this principle involves a number of caveats, but my point is that I find a Paramender or Paradjuster to be a dandy device and I experience no inconvenience using it. Others may see it differently, as I'm forced to accept that not everyone loves TLRs as I do!
