first of all,there is a lot of useful information here.thanks for that! since i am very interested in the cambo actus,maybe even more so. but on the other hand,the thread has gone in a direction wich has nothing to do with the actus any more (or at least not more than with any camera you can mount a digital back and large format lenses to.) and too much with not named dealers that might not be perfectly knowledgable or honest. of course there are dealers like that. but on the other hand,for everyone investing 50k into a system,getting information,and as much as possible,is not only recommended but a must. for me this whole crosstalk thing is completely new since i am not a digi-back shooter. i am using a mirorrless camera,and not even a full frame one but for me,the actus makes perfect sense. so i appreciate what you are telling us torger,but on one point specifically i have to disagree wholeheartedly: the actus does not only have the possibility to use digi-backs and lf lenses. my intended use is to use my fuji camera and m645 lenses,wich are retrofocus and go down to 35mm, for landscape with the ability to use tilt and swing in combination with the tilt and shift mostly to get more resolution and a broader angle of view. i donīt know yet how much movement will be possible,of course i hope it will be as much as the image circle allows,but just to test that i will check the combination for myself. i was contacting calumet in germany,they gave my number to their specialist for cambo and he will be visiting me at home probably next week to get the chance to try the camera out myself. i think of this as really really good service,and since there are quite some experiences with these leses and many different kinds of cameras with the use of adapters by mirex or kipon,wich offer tilt and shift as well i think and hope i will not face to many problems. maybe i can not use all movements to their extremes and still get perfect results,but this is pretty unlikely to do in every-day use anyway. what this means for me is that i am absolutely super glad that cambo decided to get the actus to the market! for me this is a dream come true. i sincerely hope that problems like crosstalk will get addressed in future digi back designs,and i really think this is mostly up to the producers of those and not to the companies wich build the cameras in between the backs and the lenses. there are so many possibilities to combine different kinds of equipment that you can always find something that will not work,they could all just as well simply stop producing anything then! but of course,if someone tells you that you could just use back x with camera y and lens z,takes 50grand and you find out yourself that the results are garbage, i would be pissed too! but as long as this has not happened,and even on the contrary,dealers are trying to help with solutions that will work,we are really not in the position to complain i think! i do hope that there will be a really good live-view capable digital back that has no problem with crosstalk,cause you never know... in the future i might be tempted to get one for the actus that if not total junk (wich i do not think it is..) i will be a proud owner in a week or two!
