0.7x Triplet Super Reducer

This is the prototype of part #[7870] – 0.7x triplet super reducer, which is expected to work from 300mm f.l. to 1000mm f.l. But the design looks more optimized for shorter focal length such as FL71(400mm) or shorter.

0.66x super reducer was unfortunately discontinued although it was still demanded. This is the successor to that. Moreover, it covers 35mm full frame sensor while 0.66x wasn’t.  So this should create further wider-field of view when the full frame sensor cameras are used with.  This is 1st reducer which covers full frame sensors with Mini Borg series. Originally it was expected to get available this spring. But due to the earthquake, the production is totally re-scheduled. I hope it will be this summer. We have part # 7878 – another 0.7x triplet super reducer, which works with 500mm fl.l. or longer. I will keep you updated on this including test shots.
