LOL...yeah it amounts to almost the same thing.....I only have up to 450 mm and I have plenty of bellows left, for landscape you should not have a problem. if your choice is to shoot wideangle in 35 mm then you definitly wont have a problem. With a bellows draw of 30 inches you can go up to 600 mm and still have a comfortable margin for closer objects so this should not be an issue for landscape.
As I said the Gandolfi for the price is a good camera, Canham, Wisner, Ebony, toyo, etc are all also good.
