RULES: CONSIDERING SIZE/WEIGHT... vs. QUALITY -- NOT ECONOMY!!! Has anyone directly compared an "optimized" 6x12cm "full system" (camera/lenses/size/weight) compared to an "optimized" 5x10in (camera/lenses/size/weight) system? It seems to me that a mini 6x12cm system is really no smaller/lighter than a 5x10in system. Has anyone actually measured the "smaller system" to the "larger" one? What I'm proposing is a 5x10in system taking TWO 5x7in images stiched to complete a 5x10" image (shift/stitch). A 5x10in image stitched is far superior to a 6x12cm image, IMO. If you want to compare a "6x12cm image to a stitched 5x10in image that's okay. I've been observing the differences and it seems that a 6x12cm system is not that much smaller than a 5x7in system stitched to 5x10in. What are your thoughts?? Yes, I know there is a difference in film/processing costs.
