Cooke Telepanchro – Taylor Hobson 317mm T4 Prime
The Taylor Hobson 317mm T4 is the perfect complement to our Cooke Speed Panchros. This 12 and a half inch prime lens offers unparalleled quality with warm image tones and a circular iris opening for a rounded bokeh.
Other similar qualities to the Cooke Speed Panchros include the characteristic breathing and outer third drop-off. This lens is so versatile that you can shoot wide open at T4 for a slight warm halo or stop down to T5.6 for a sharper rendition for that classic “Cooke look.”
