I think everyone has given quite positive advice so far on this, which I am pleasantly surprised. I originally thought of a 6x12 but that is not a big enough step up from my Mamiya 7ii. So a 6x17 or 6x24 became the choice, I blame Lee Frost and his book “Panoramic Photography” which I drooled over for months.
I Must admit I’m still worried about how well the 90/5.6 Super Angulon XL lense will work as it is near its maximum of 259mm on the 6x24
