In looking over the upcoming DA560, I couldn't get it out of my head how "Telescope" the lens appeared to me. I have an old Pentax telescope, and with a little searching around the web, I found out some interesting things about a company called BORG Oasis studio.
Hutech Astronomical Products - Borg Telescopes
Bo-enkyo- (telescope) - Do-gu (equipment)
It seems that a Mr. Nakagawa is responsible for the design of the 125SD and his philosophy is..
"Photo-visual design with no compromises was a primary concern of the system designer at Borg, an accomplished photographer with decades of experience. Borg scopes fully cover the 6x7 cm frame of the popular medium format Pentax 67 series cameras, and include photographer's extras such as a precise, indexed, lockable (two lockscrews) helical focuser and a full range of field flatteners and teleconverters. Also available are a full line of 35mm camera accessories and visual adapters. "
So the 125SD?
Hutech Astronomical Products - Borg 125SD
That telescope - is VERY similar to the upcoming DA560mm. Even on the BORG web site they say - "Featuring a collaboration between Borg and Pentax on a new objective design. "
So it appears that the 125SD and Mr. Nakagawa have a serious Pentax connection, and if the BORG Oasis Studio is going to make the new DA560mm it would appear that the new lens will be made in Japan, as the 125SD is.
I wonder if Mr. Nakagawa was one of the engineers Hoya fired/laid off?
