  1. ever wondered what leica or cooke taylor hobson could do if they made something like the tokina achromatic diopter.   well in about 3 weeks i should have the finest close up ever. 82mm doublet +0.25 classic single coated optics using ohara and schott germany glass. way superior than the tokina +0.4 optimised for 5d size sensor using iscorama,cooke speed panchro and leica r as the set up. this close up will be a fine match for the finest most expensive high end new or old optics.     anyone who thinks these new generation anamorphics from letus and slr magic will not need a double element close optics is clearly not very sharp : ) a simple test on those 2 new china lens shot at f1.8 or even f2.8  with an achromatic doublet and without should make things clear. these new anamorphics are single element  optics just like the century and the panasonic optics. maybe revised and improved  but still single element.. sometin got a give somewhere in the system.   as we all understand stopping optics down to f4-5.6 clears up the image and makes even poor optics look sweet. achromatic correction is kind of cool and if you like the new anamorphic lens concepts coming sticking a decent bit of double element glass in front of bad single element can only help A 3 cheers for Chester Moore Hall the man that came up with the concept of bending light ray achromatic correction.

  2. it has been designed around the best optics i have cooke speed panchro,leica noctilux,nikon noct imaging onto a 5d sensor size. i took the best designs i could find realised most achromats are design for long and zoom lens so started from scratch again. so although the tokina is the best of it's type in terms of light ray path my new ones have better correction hitting the film plane. the quality of my glass is better and more exotic than the tokina and fully configured for the job. no price at the moment but you can test it when i get time to machine a mount for it : )
