Rob, I enjoy my health care so I think I will stay slightly to the left, if you don't mind. But seriously, my observation with you 6x6 guys is that you tend to like what you worked with for many years. FWIW, I did a wee bit of 6x6 slides and simply adapted. Did the same with 4x5 and cell phone 2x5. Now I tend to like 4x6 having worked with it for so many years, though I agree with many that 4x5 is probably the ideal format. So here is square fix for you from the industrial establishment, so to speak.

That's why I love both the square
and the standard 135 format of 2x3.
Both have their uses and moments; in my case, the 6x6 camera was always a tripod-mounted device except for the Rollei TLR which had no mirror bounce [being heavy(ish), and with a Synchro Compur shutter, it was very handheld-friendly]. If it did have mirror bounce, you had a serious problem with your viewfinder!
