Only BTZS prints I have ever see an photo magazine article , first result when you searched and everything was awful , other source was their forum where there were awful pictures. John Sexton prints are amazing , I havent an idea he used the system , IMHO japanese optics are the enemy of good photography , if you want a good print , you must be 4 times luckier than german optics user. They always trace a wrong doing in the photograph , I want to talk about optics , if you change the distances between elements , you can get over corrected , high contrast images , this is for nikon and mamiya users , they dont design perfect lenses , they manufacture over corrected lenses and everything gets blown , colors goes ugly , high light details lost , ugly noise apeears and whats not.
At classifieds a nikon em goes for 10 dollars and lens goes for 10 dollars. Real photographers only pay that price to them. I always discusted from nikon since I was 14. There were hundreds of chromatic not corrected pictures at photo technique and amateur photographer.
I did not hear that Ansel and Edward Weston ever used japanese optics , in 1924 there were 3000 optics manufacturer at Germany and since that time they published highly technical 3500 books.
If I was young and still working , own a Leica and money for film and travel , I would show you how German optics work. There are few pictures from that time at gallery and they speak for themselves.
