For what it is worth, the Kinoptik Tegea T2 5.7mm lens for 16mm film cameras, is sweetest on the sharpness numbers on the SI2K at aperture a trace under T2.8, one millimetre under the mark on the small aperture ring. It comes up to about 80% of the real world sharpness of the best of my CP Ultras.
The Kinoptik Tegea T2.3 9.8mm is sweetest on the numbers at about T3. As far as sharpness goes, it is not so good across a Super16mm frame, at best about half as crisp as the 9mm CP UltraT*. This is understandable as it is a 35mm film lens. The CP is a purposed 16mm film camera lens.
My conclusion is not a competent technical assessment against Putora charts with controlled lighting but perhaps more of an indicator of performance under realworld conditions.
My usual caveat on my comments applies. Please heed the info from more competent people than I.
