Would any cable release work such as available for 35mm SLR's or is there a special size I need for the Hasselblads? Am playing with macro and Acros so I am going to order a release when I order more fixer from B&H. What type of locks on the cable (disc, T type) are preferable? Is there a limit on length of cable that one would not go beyond? I am thinking about the Linholf releases but are they made for large format only or does it matter?
