Arriving late to this thread, I have to say that "evil SLRs" sounds to me like a joke and nothing else, as most of us in the RFF forum have both types of cameras and most important, use them for what they were designed for, it is taking pictures, pictures as good as the man behind can do.
I got to admit that since 2003 I´m using mostly RF cameras just because that I found that for the pictures I like to take, the ol´n´trusty RFs are well (would I say almost) perfectly suited.
Nevertheless I do not dislike neither SLRs nor TLRs because they are excellent cameras and I feel great pleasure using them. I use (not too often) field and view cameras which are not suited for street photo nor are "fast", but the pleasure of using this old style cameras is something I would strongly recommend to any one involved in photography, as the are the same type of cameras that started this endless illness.
So I take the phrase "evil SLRs" as nothing more than a joke, not (obviously) to be seriously taken (even for RFs users!).
BTW, I´m starting on August a workshop of Pinhole cameras...
Cheers
