hi -- have been using dorff 8/10 with 4/5 reducing back for a number of years, primarily in order to get good bellows extension for long lenses (love using the 450 nikkor at relatively close distances, etc). however, the camera is heavy to say the least. have a technika but really feel limited with the bellows amd so don't use it as much. also find superwides easier to deal with on the deardorff used with the 8/10 back than the technika at 4/5. it is great how stable and easy to use the camera is at both extremes. but, again, the weight is an issue, and i just can't take the camera everywhere i'd like to go.
my question is this, is there a 4/5 or 5/7 alternative that would be much lighter, but that would still give me big bellows extension (over 22 inches), be stable at the long extensions, and be easy to use in the superwide range (say 65mm, not 47mm)??
thanks for your input.
