Thank for your response Denis,
What are you using to convert the Raw files the Leaf software or Adobe Camera Raw?
Good to hear that the Mamiya is working out for you? The lack of WLF was a big turn off for me but so is cables hanging out of the camera on a Hassy 503. I don't care for the H1 and very expensive as well.
Everyone seems to say that the A65 is a cropped A75 sensor and that the P30 is cropped from the P45, yet the at the same time they mention wide angle behavior on the smaller sensors is different because of the micro lenses in the sensor. It is very confusing and the only way is to try it for myself.
I seek the opinions of the users in this forum since I have not been able to get a hold of an Aptus 65 and perhaps someone might have or is doing the same homework. I reached my limit of patience with the Canon 1DsMK2 and the countless hours of post processing is crazy.
