Hello again, Having considered my options, I'm tending towards getting one of the lighter monorails, like the Sinar F or A, given long lens use, weight, and price considerations. Basically the only field cam that allows some long lens use under $1000, the Shen HAo, is almost as heavy as a light monorail (6lbs SH vs 7lbs Sinar A/F). Since I don't backpack, because of back problems, but rather carry my gear using a little cart, I'm wondering whether it doesn't make more sense for me to go w a monorail. So I was curious if there are any photographers out there using monorails in the field, and what you can report from such use. I especially want to be able to use lenses in the 400mm range, and the price difference is also tempting. Thanks in advance.
