When I bought a 500CM body off KEH, it came with the cross reference screen and that thing was just terrible. Then, I ended up buying a split-image screen, and its helped a lot, but I'm still not satisfied. So, now I'm actually considering selling my hasselblad instead of buying an acute matte screen. I'd rather buy a bunch of film.

I ended up spending a lot on a late A12 back, the one with the leatherette on the button and a dark slide holder, and have had no problems even though one of the hooks on my CM body is slightly bent too.

Other than the focusing problems it's a great camera. I just can't understand why the plastic screen in the Bronica SQ was so much easier to focus for me.
