Originally posted by tonyzoc I think the EC, which followed the S line, was an improved camera, though it still used the split mirror system. Bonica did have a leaf shutter lens but it was awkward to use. With the success of the ETR system, they eventually produced the SQ 6x6, which is a camera I've always wanted. They also put out the GS 6x7. I just have the EC with the 75/2.8 PC Nikkor, a 50mm Nikkor and a 150mm Zenzanon. I got the whole kit for under $600. I use it once in a while but it is a boat anchor to carry around.
I really liked the SQ... good ergonomics, good lenses...
I want to say the model I used was a SQai? with TTL flash...
They're a bit larger than a Hasselblad as I recall, especially with the grip (which is on the right and winds the film with a thumb lever) and eye-level finder, but not obnoxiously so.
