    Pawel,

    Is this the "on-axis" MTF. What about off axis? I also expect a very decent difference at 2.8 and 4.5. At 4.5, these lenses should have a 4.5/2.8 larger airy disk. When slowed down so...

    S4's

    One of the reason Cooke's look warmer is that they are using 15 year old glass. There have been many developments in high blue transmission glasses and a modern lens design should look whiter since...

    Tecentric

    Pawel,

    There is object side and image side telecentricity. Machine vision lenses are object side. You are correct that the subject has to be smaller than the front lens in that case. They are...

    Telecentric

    Telecentric has field illumination advantages (not straight cos4 loss). However, there are mechanical size requirements for such a lens. In large format S35 and higher cine lenses, the limitation...

    Image Circle

    You would measure the image circle by determining the relative illumination you could live with in the corners. Rule of thumb is anything under 40% you will perceive. 50%-60% will look very...
