Too Cool! A true Milestone in 4x5 Polaroid 110B tecnology.
You are the Zen Master of the Big, Big Xenotar!
I have customers that want a 150mm Xenotar conversion, they will be in touch with you soon, Xenotar Mania Lives!
Myself, Noah, Dean and Nate have beaten down the Grinch in New York! So Glad he has not bothered you, he must know his arse is beat!
Now if I could just get a few more of those 135mm f3.5 Xenotars.........
First I'd just like to say you do beautiful work, some of the best back and rail systems I've seen, super clean and smooth. The info here was very informative as I'm having a small issue coupling the rangefinder on my 900. I'm using a 150mm Calumet Caltar Type-S f/5,6 on a home made standard from hard woods. I'm still working to get the 150mm into infinity due to the stop won't reach far enough back. I've installed a 600SE release for removable backs and this is what( I truly believe) has caused the problems as it to far off to reach because the 900s infinity stop only goes back to the focus wheel. All I need is about 5mm more but have not found a way around this due to there is a need for the standard to clip into the bracket from all the weight up there. I've been trying to come up with some sort of other clip for the Mamiya backs (these are my favorite films, cheap, easy to find on trips and I get 120, cut film, small wet plates and Impossible films as well) but nothing that's stable enough so far to trust out in the field. As i'm sure you know the bracket for the film backs is fairly thick and if there was another way to not use piece I would. I've tried my 210mm but of coarse this is way to much. I've been looking for some time now to find a better way, It was all put together and out taking beautiful shots with it but of coarse I was dependent on the ground glass till this issue is resolved, so it has been disassembled until a way is found but as you could guess I'm really excited to get it back together to go out and play. If you have any suggestions i'd be open to anything, all I have is limited tools and most the work is done by hand so I'm limited by this.
