Let me have a take on the matters
- First and foremost, forget about the digital back. Simply put, a digital back does not make sense in a 6X7 format. The technogy had different application adn there is a depreciation of return with size advantage. the current Digital back and future extreme high resolution models ( say like the 39MP Phase one P45 ) are all 36X48. There is a limit on the chip and sensor both for practical and technical reason. If Digital back is a concern, stay 645 and think of investing in better Lens
- If you routinely need large print, do your own post processing ( wet or digital ) and can afford the size advantage. the 6X7 ( or rather 6X8 ) is preferably a better advantage. But You got to live with the size disadvantage also. Handliing a 6X7 is not like 645. 645 is very much grown up from 35mm, but 67 is very much a slimmed down large format. Don't even think of doing handheld in most cases.
- Large Format is not about darkrooming. Its about getting the most out of the media. I use 35mm, 645 & 6X6, but beyond that I will not go for a 6X7 or 6X8 personally. They are really catered for commercial application. Any decent large format can easily adepted to take roll film back, and with the capbility of the field camera which offer far more control over any 6X7 or 6X8 SLR. It dwells on the fact that unless one are using tthose SLR for need. No reason can sway me from notgoing the large format route. Especially something like a 5X7 which allow reduced back to 4X5 or roll film back up to 617 ( without needing extension frame and thus allow true ultra wide ). Tell you what, one don't know larger format until one tried out a 8X10 ( talk about contact print or viewing )
So in the end, I think just thinking of the 6X7 as a step up from 645 is IMHO a grossly unjusted idea. If one cannot realize the fact in operational difference. One cannot appreciate how such a system is so differed from 645. Especially as the stated position of not using Waist Level ( Care to guess how big, heavy and dark such prism as was on the 6X7 or so ) ..... That aside, the Pentax 6X7 is far more suitable to 645/35mm user with preference fro Prism than anything else.
FR,
the first part about large format makes sense to me, that's why i do not consider trying it out and asked about 6x7 instead, what u referred to as a trimmed down large format - since i am very much interested in seeing frame size larger than 645.
i asked a bit about the horseman earlier on because it is of a larger frame size and i like panorama. but this guess work about focusing beats me. So, it's a "forget it".
no, i don't do my own printing and i do not intend to, not at this stage anyway.
yes, shopping and playing with / getting to know different cameras is an integral part of my interest in photography.
i like pentax because i am very used to composing through a prism as opposed to a waist level finder, but the build in bellow focusing (more than the prospect about the use of a digital back) of the rz interests me.
about your latter part, u think it's a good idea to try out the pentax if i want to look at something bigger than 645 ? is that what u mean ?
