IDAS UV filter (part # UV372-80) is now available.
Response curve (actually measured)
Optical density (actually measured)
This filter should be very useful for enhancing the visibility of Mars’s atmospheric water vapor clouds as well as increasing the contrast of Venus’s lower atmosphere cloud structures. Keep in mind, this filter is well designed to minimize transmission leak in VIS and IR very much. Surprisingly OD 8 to 9 in VIS region!! Probably I can say virtually no leak. As a result, it creates extremely high contrast image.
This UV filter also works for special scientific imaging such as plants, insects and human skins as well as forensic research.
Two sizes – M52 and M28.6 are available.
UV372-80-286 : $309.00
UV372-80-52 : $309.00
As always, IDAS filters are all well made. I believe this should be the best UV filter currently available in the market.

Gakken, a giant of educational kit provider in Japan has introduced the unique spherical projector, called “WorldEye”.
When projected in the dark room, the Jupiter and the moon look like floating around the air. It’s very cool. I’m so impressed. So I wanted to try to share with you. My PV doesn’t look like professional grade like Gakken’s though.
WorldEye will be available worldwide soon. USB and HDMI interfaces are very nice, which allow to enjoy user’s original video and time lapse movie.
I will show more movie at this blog.

Japanese people enjoy the party under blossom, especially plum(or Japanese apricot?) and cherry. These are taken with BORG 50/F2.8 and Sony Alpha 7R. All are not cropped.

This lens is expected to be released this summer. Looking very good color contrast entire full frame sensor.
67FL + Fuji X-T1
All are taken in X-T1 Velvia mode
Mejiro – Japanese white-eye and Ume(Japanese apricot) are the typical combination from long-time ago.

During CP+ (largest photographic show in Japan), BORG announced following new products scheduled to come up 2014.
1) 2014×1 – 90FL, 500mm/F5.6 fluorite telephoto lens
This was informed at this blog several days ago. But first public show-up.
2) 2014×2 – 55FL, 250mm/F4.5 fluorite telephoto lens
250mm focal length is same as 50Ach. So it should be very compact. This will be super finder, guider and imager. It should be wonderful scope for wide-field astrophotography.
3) 50mm/F2.8 wide-angle lens
This is originally designed as enlarging lens and will be shortest focal length in BORG optics. It should be used with M42 helical focuser and back focus is optimized for short flange back camera such as mirrorless bodies. This lens will be great for macro as well as wide-field astrophoto one too.
BTW, BORG is now an official member for micro four thirds group.
4) Super reducers for 90FL, 71FL and 67FL
Unlike current universal optical design, these are individually optimized for each 90FL, 71FL and 67FL and cover full frame sensors.
5) And finally BORG plans to release the mount adapter for Leica M camera. This is 1st collaboration with Leica.
I was told so many people stopped by BORG booth.

BORG 67FL – 300mm fluorite telephoto lens is quite compact and light weight. Super fast – F4.5 (feel like F3.3 or faster) allows for higher shutter speed and create beautiful “Bokeh”. See some photos recently taken by Noboru Nakagawa.
67FL + Olympus E-P5
Only 2-elements lens creates very clean and high contrast result.
